I’m iron deficient. Which supplements will work best for me and how should I take them?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/alannah-mckay-1548258">Alannah McKay</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a></em></p> <p>Iron deficiency is common and can be debilitating. It mainly affects women. One in three premenopausal women <a href="https://static1.squarespace.com/static/57bfc0498419c24a01318ae2/t/607fc2e06ace2f22d5ca9a43/1618985699483/20210421+-+IDC+-+economic+impact+of+iron+deficiency+-+FINAL.pdf">are low in iron</a> compared to just 5% of Australian men. Iron deficiency particularly affects teenage girls, women who do a lot of exercise and those who are pregnant.</p> <p>The <a href="https://pubmed.ncbi.nlm.nih.gov/11160590/">body needs iron</a> to make new red blood cells, and to support energy production, the immune system and cognitive function. If you’re low, you may experience a range of symptoms including fatigue, weakness, shortness of breath, headache, irregular heartbeat and reduced concentration.</p> <p>If a blood test shows you’re iron deficient, your doctor may recommend you start taking an oral iron supplement. But should you take a tablet or a liquid? With food or not? And when is the best time of day?</p> <p>Here are some tips to help you work out how, when and what iron supplement to take.</p> <h2>How do I pick the right iron supplement?</h2> <p>The iron in your body is called “elemental iron”. Choosing the right oral supplement and dose will depend on how much elemental iron it has – your doctor will advise exactly how much you need.</p> <p>The sweet spot is between <a href="https://www.sciencedirect.com/science/article/pii/S0098299720300364?via%3Dihub">60-120 mg of elemental iron</a>. Any less and the supplement won’t be effective in topping up your iron levels. Any higher and you risk gastrointestinal symptoms such as diarrhoea, cramping and stomach pain.</p> <p>In Australia, iron salts are the most common oral supplements because they are cheap, effective and come in different delivery methods (tablets, capsules, liquid formulas). <a href="https://www.ncbi.nlm.nih.gov/books/NBK557376/">The iron salts</a> you are most likely to find in your local chemist are ferrous sulfate (~20% elemental iron), ferrous gluconate (~12%) and ferrous fumarate (~33%).</p> <p>These formulations <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3867244/">all work similarly</a>, so your choice should come down to dose and cost.</p> <p>Many multivitamins may look like an iron supplement, but it’s important to note they usually have too little iron – usually less than 20 mg – to correct an iron deficiency.</p> <h2>Should I take tablets or liquid formulas?</h2> <p>Iron contained within a tablet is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3867244/">just as well absorbed</a> as iron found in a liquid supplement. Choosing the right one usually comes down to personal preference.</p> <p>The main difference is that liquid formulas tend to contain less iron than tablets. That means you might need to take more of the product to get the right dose, so using a liquid supplement could work out to be more expensive in the long term.</p> <h2>What should I eat with my iron supplement?</h2> <p>Research <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1002/ajh.26987">has shown</a> you will absorb more of the iron in your supplement if you take it on an empty stomach. But this can cause more gastrointestinal issues, so might not be practical for everyone.</p> <p>If you do take your supplement with meals, it’s important to think about what types of food will boost – rather than limit – iron absorption. For example, taking the supplement alongside vitamin C improves your body’s ability to absorb it.</p> <p>Some supplements already contain vitamin C. Otherwise you could take the supplement along with a glass of orange juice, or other <a href="https://ods.od.nih.gov/factsheets/VitaminC-HealthProfessional/">vitamin C-rich foods</a>.</p> <p>On the other hand, tea, coffee and calcium all <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1002/ajh.26987">decrease the body’s ability to absorb iron</a>. So you should try to limit these close to the time you take your supplement.</p> <h2>Should I take my supplement in the morning or evening?</h2> <p>The best time of day to take your supplement is in the morning. The body can <a href="https://journals.lww.com/acsm-msse/fulltext/2019/10000/the_impact_of_morning_versus_afternoon_exercise_on.20.aspx">absorb significantly more</a> iron earlier in the day, when concentrations of hepcidin (the main hormone that regulates iron) are at their lowest.</p> <p>Exercise also affects the hormone that regulates iron. That means taking your iron supplement after exercising can <a href="https://journals.humankinetics.com/view/journals/ijsnem/32/5/article-p359.xml">limit your ability to absorb it</a>. Taking your supplement in the hours following exercise will mean significantly poorer absorption, especially if you take it between two and five hours after you stop.</p> <p><a href="https://journals.lww.com/acsm-msse/fulltext/2024/01000/iron_absorption_in_highly_trained_male_runners_.14.aspx">Our research</a> has shown if you exercise every day, the best time to take your supplement is in the morning before training, or immediately after (within 30 minutes).</p> <h2>My supplements are upsetting my stomach. What should I do?</h2> <p>If you experience gastrointestinal side effects such as diarrhoea or cramps when you take iron supplements, you may want to consider taking your supplement every second day, rather than daily.</p> <p>Taking a supplement every day is still the fastest way to restore your iron levels. But a recent study <a href="https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(23)00463-7/fulltext#%20">has shown</a> taking the same total dose can be just as effective when it’s taken on alternate days. For example, taking a supplement every day for three months works as well as every second day for six months. This results in fewer side effects.</p> <p>Oral iron supplements can be a cheap and easy way to correct an iron deficiency. But ensuring you are taking the right product, under the right conditions, is crucial for their success.</p> <p>It’s also important to check your iron levels prior to commencing iron supplementation and do so only under medical advice. In large amounts, <a href="https://www.ncbi.nlm.nih.gov/books/NBK430862/">iron can be toxic</a>, so you don’t want to be consuming additional iron if your body doesn’t need it.</p> <p>If you think you may be low on iron, talk to your GP to find out your best options.<!-- Below is The Conversation's page counter tag.

Vitamins and supplements: what you need to know before taking them

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/neelaveni-padayachee-1018709">Neelaveni Padayachee</a>, <a href="https://theconversation.com/institutions/university-of-the-witwatersrand-894">University of the Witwatersrand</a> and <a href="https://theconversation.com/profiles/varsha-bangalee-1253468">Varsha Bangalee</a>, <a href="https://theconversation.com/institutions/university-of-kwazulu-natal-1941">University of KwaZulu-Natal</a></em></p> <p>If you were to open your medicine cabinet right now, there’s a fair chance that you’d find at least one bottle of vitamins alongside the painkillers, plasters and cough syrup.</p> <p>After all, people are definitely buying vitamins: in 2020, the global market for complementary and alternative medicines, which includes multivitamin supplements, had an estimated value of <a href="https://www.grandviewresearch.com/industry-analysis/complementary-alternative-medicine-market">US$82.27 billion</a>. The use of natural health products such as minerals and amino acids has <a href="https://journals.lww.com/nutritiontodayonline/Abstract/2007/03000/Why_People_Use_Vitamin_and_Mineral_Supplements.4.aspx">increased</a> – and continues to rise, partly driven by consumers’ buying habits during the COVID-19 pandemic.</p> <p>People <a href="https://www.businesslive.co.za/bd/companies/healthcare/2021-02-08-native-sales-of-sas-vitamins-and-nutritional-supplements-boom/">sought out</a> vitamins C and D, as well as zinc supplements, as potential preventive measures against the virus – even though the <a href="https://www.health.harvard.edu/blog/do-vitamin-d-zinc-and-other-supplements-help-prevent-covid-19-or-hasten-healing-2021040522310">evidence</a> for their efficacy was, and <a href="https://pubmed.ncbi.nlm.nih.gov/35888660/#:%7E:text=Concluding%2C%20available%20data%20on%20the,trials%20(RCTs)%20are%20inconsistent">remains</a>, inconclusive.</p> <p>Multivitamins and mineral supplements are easily accessible to consumers. They are often marketed for their health claims and benefits – sometimes unsubstantiated. But their potential adverse effects are not always stated on the packaging.</p> <p>Collectively, vitamins and minerals are known as micronutrients. They are essential elements needed for our bodies to function properly. Our bodies can only produce micronutrients in small amounts or not at all. We get the bulk of these nutrients <a href="https://www.iprjb.org/journals/index.php/IJF/article/view/1024">from our diets</a>.</p> <p>People usually buy micronutrients to protect against disease or as dietary “insurance”, in case they are not getting sufficient quantities from their diets.</p> <p>There’s a common perception that these supplements are harmless. But they can be dangerous at incorrect dosages. They provide a false sense of hope, pose a risk of drug interactions – and can delay more effective treatment.</p> <h2>Benefits</h2> <p>Vitamins are beneficial if taken for the correct reasons and as prescribed by your doctor. For example, folic acid supplementation in pregnant women has been shown to prevent neural tube defects. And individuals who reduce their intake of red meat without increasing legume consumption require a vitamin B6 supplement.</p> <p>But a worrying trend is increasing among consumers: intravenous vitamin therapy, which is often punted by celebrities and social media marketing. Intravenous vitamins, nutrients and fluids are administered at pharmacies as well as beauty spas, and more recently “<a href="https://www.health.harvard.edu/blog/drip-bar-should-you-get-an-iv-on-demand-2018092814899">IV bars</a>”. Users believe these treatments can quell a cold, slow the effects of ageing, brighten skin, fix a hangover or just make them feel well.</p> <p>Intravenous vitamin therapy was previously only used in medical settings to help patients who could not swallow, needed fluid replacements or had an electrolyte imbalance.</p> <p>However, the evidence to support other benefits of intravenous vitamin therapy is limited. No matter how you choose to get additional vitamins, there are risks.</p> <h2>Warning bells</h2> <p>Most consumers use multivitamins. But others take large doses of single nutrients, especially vitamin C, iron and calcium.</p> <p>As lecturers in pharmacy practice, we think it’s important to highlight the potential adverse effects of commonly used vitamins and minerals:</p> <ul> <li> <p><a href="https://www.hsph.harvard.edu/nutritionsource/vitamin-a/">Vitamin A/retinol</a> is beneficial in maintaining good eye health. But it can cause toxicity if more than 300,000IU (units) is ingested. Chronic toxicity (hypervitaminosis) has been <a href="https://www.ncbi.nlm.nih.gov/books/NBK532916/">associated</a> with doses higher than 10,000IU a day. Symptoms include liver impairment, loss of vision and intracranial hypertension. It can cause birth defects in pregnant women.</p> </li> <li> <p><a href="https://www.hsph.harvard.edu/nutritionsource/niacin-vitamin-b3/">Vitamin B3</a> is beneficial for nervous and digestive system health. At moderate to high doses it can cause peripheral vasodilation (widening or dilating of the blood vessels at the extremities, such as the legs and arms), resulting in skin flushing, burning sensation, pruritis (itchiness of the skin) and hypotension (low blood pressure).</p> </li> <li> <p><a href="https://www.hsph.harvard.edu/nutritionsource/vitamin-b6/">Vitamin B6</a> is essential for brain development and in ensuring that the immune system remains healthy. But it can result in damage to the peripheral nerves, such as those in the hands and feet (causing a sensation of numbness and often referred to as pins and needles) at doses over 200mg/daily.</p> </li> <li> <p><a href="https://www.hsph.harvard.edu/nutritionsource/vitamin-c/">Vitamin C</a> is an antioxidant and assists in the repair of body tissue. Taken in high doses it can cause kidney stones and interactions with drugs, such as the oncology drugs doxorubicin, methotrexate, cisplatin and vincristine.</p> </li> <li> <p><a href="https://www.hsph.harvard.edu/nutritionsource/vitamin-d/">Vitamin D</a> is essential for bone and teeth development. At high doses it can cause hypercalcaemia (calcium level in the blood is above normal) that results in thirst, excessive urination, seizures, coma and death.</p> </li> <li> <p><a href="https://www.hsph.harvard.edu/nutritionsource/calcium/#:%7E:text=Calcium%20is%20a%20mineral%20most,heart%20rhythms%20and%20nerve%20functions">Calcium</a> is essential for bone health, but can cause constipation and gastric reflux. High doses can cause hypercalciuria (increased calcium in the urine), kidney stones and secondary hypoparathyroidism (underactive parathyroid gland). It can have drug interactions with zinc, magnesium and iron.</p> </li> <li> <p><a href="https://www.hsph.harvard.edu/nutritionsource/magnesium/">Magnesium</a> is important for muscle and nerve functioning. At high doses it can cause diarrhoea, nausea and abdominal cramping, and can interact with tetracyclines (antibiotics).</p> </li> <li> <p>Zinc <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7781367/">can impair</a> taste and smell, and doses over 80mg daily have been <a href="https://link.springer.com/article/10.1007/s10654-022-00922-0#:%7E:text=Zinc%20supplementation%20of%20more%20than,zinc%20supplements%20among%20adult%20men.">shown</a> to have adverse prostate effects.</p> </li> <li> <p><a href="https://www.hsph.harvard.edu/nutritionsource/selenium/">Selenium</a> can cause hair and nail loss or brittleness, lesions of the skin and nervous system, skin rashes, fatigue and mood irritability at high doses.</p> </li> <li> <p><a href="https://www.sciencedirect.com/science/article/pii/S0098299720300364#:%7E:text=Expert%20guidelines%20for%20oral%20iron%20supplementation&amp;text=Traditionally%2C%20the%20recommended%20daily%20dose,iron%20(Brittenham%2C%202018).">Iron</a> at 100-200mg/day can cause constipation, black faeces, black discoloration of teeth and abdominal pain.</p> </li> </ul> <h2>Recommendations</h2> <p>People need to make <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8377299/">informed decisions</a> based on evidence before consuming health products.</p> <p>Regular exercise and a well-balanced diet are more likely to do us good, as well as being lighter on the pocket.</p> <p>Seeking advice from a healthcare professional before consuming supplements can reduce the risk of adverse effects.</p> <p>Be aware of the potential adverse effects of vitamins and seek a healthcare professional’s guidance if you have symptoms.<!-- Below is The Conversation's page counter tag.

Vitamin D supplements can keep bones strong – but they may also have other benefits to your health

<p><em><a href="https://theconversation.com/profiles/martin-hewison-1494746">Martin Hewison</a>, <a href="https://theconversation.com/institutions/university-of-birmingham-1138">University of Birmingham</a></em></p> <p>Most of us don’t worry about getting vitamin D when the weather’s warm and the sun is shining. But as winter approaches, accompanied by overcast days and long nights, you may be wondering if it could be useful to take a vitamin D supplement – and what benefit it might have.</p> <p>During the summer, the best way to get vitamin D is by getting a bit of sunshine. Ultraviolet rays (specifically UVB, which have a shorter wavelength) interact with a form of cholesterol called <a href="https://www.ncbi.nlm.nih.gov/books/NBK278935/">7-dehydrocholesterol</a> in the skin, which is then converted into vitamin D.</p> <p>Because vitamin D production is dependent on UVB, this means our ability to make it <a href="https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-d/#:%7E:text=From%20about%20late%20March%2Fearly,enough%20vitamin%20D%20from%20sunlight.">declines in the winter months</a>. Vitamin D production also <a href="https://pubmed.ncbi.nlm.nih.gov/24494042/">depends on where you live</a>, with people living nearer to the equator making more vitamin D than those living nearer the poles.</p> <p>Vitamin D deficiency is a <a href="https://assets.publishing.service.gov.uk/media/5a804e36ed915d74e622dafa/SACN_Vitamin_D_and_Health_report.pdf">problem in the UK</a> during the winter months. This is due to its northerly position and cloudy weather, and lack of time spent outdoors.</p> <p>One study of over 440,000 people in the UK found that <a href="https://pubmed.ncbi.nlm.nih.gov/33309415/">18% were vitamin D deficient</a> during the winter months. Vitamin D deficiency was even higher in certain ethnic groups – with the data showing 57% of Asian participants and 38% of black participants were vitamin D deficient. This is because the melanin content of skin determines a person’s ability to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5946242/#:%7E:text=Skin%20pigmentation%2C%20i.e.%2C%20melanin%2C,%5B7%5D%20and%20more%20generally.">make UVB into vitamin D</a>.</p> <p>Given the prevalence of vitamin D deficiency in the UK, and the importance it has for our health, in 2016 the UK’s Science Advisory Council on Nutrition outlined recommendations for the <a href="https://www.gov.uk/government/publications/sacn-vitamin-d-and-health-report#:%7E:text=In%20a%20change%20to%20previous,aged%204%20years%20and%20older">amount of vitamin D</a> people should aim to get in the winter.</p> <p>They recommend people aim to get ten micrograms (or 400 IU – international units) of vitamin D per day. This would help people avoid severe deficiency. This can be achieved either by taking a supplement, or eating <a href="https://www.bhf.org.uk/informationsupport/heart-matters-magazine/nutrition/ask-the-expert/foods-high-in-vitamin-d">certain foods</a> that are rich in vitamin D – including fatty fish such as herring, mackerel and wild salmon. A 100 gram serving of fresh herring, for example, would have approximately five micrograms of vitamin D.</p> <p>The clearest benefit of taking a vitamin D supplement is for <a href="https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-d/">bone health</a>. In fact, vitamin D was <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3899558/">first discovered</a> 100 years ago because of its ability to prevent the disease rickets, which causes weak bones that bend.</p> <p>Although rickets <a href="https://www.nhs.uk/conditions/rickets-and-osteomalacia/#:%7E:text=The%20number%20of%20rickets%20cases,from%20sunlight%2C%20can%20develop%20rickets.">isn’t very common</a> in the UK today, it can still occur in children if they lack vitamin D. In adults, vitamin D deficiency can cause bone pain, tenderness and muscles weakness, as well as increased risk of osteomalacia – often called “soft bone disease” – which leads to weakening or softening bones.</p> <p>The reason a lack of vitamin D can have such an effect on bone health is due to the vitamin’s relationship with <a href="https://pubmed.ncbi.nlm.nih.gov/18844850/">calcium and phosphate</a>. Both of these minerals help keep our bones strong – but they require vitamin D in order to be able to reinforce and strengthen bones.</p> <h2>Other health benefits</h2> <p>In addition to its effects on the skeleton, a growing body of research is beginning to indicate that vitamin D supplements may have additional benefits to our health.</p> <p>For example, <a href="https://ar.iiarjournals.org/content/42/10/5009.long">research shows</a> there’s a link between vitamin D deficiency and increased risk of catching certain viral illnesses, including the <a href="https://pubmed.ncbi.nlm.nih.gov/19237723/">common cold</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7231123/">flu</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7385774/">COVID</a>.</p> <p>Similarly, several studies – <a href="https://pubmed.ncbi.nlm.nih.gov/32904944/">including my own</a> – have demonstrated in cell models that vitamin D promotes immunity against microbes, such as the bacteria which causes tuberculosis. This means vitamin D may potentially prevent some types of infections.</p> <p>Vitamin D may also dampen inflammatory immune responses, which could potentially protect against autoimmune diseases, such as <a href="https://pubmed.ncbi.nlm.nih.gov/29243029/">multiple sclerosis</a> and <a href="https://www.frontiersin.org/articles/10.3389/fmed.2020.596007/full">rheumatoid arthritis</a>.</p> <p>One 2022 trial, which looked at over 25,000 people over the age of 50, found taking a 2,000 IU (50 micrograms) vitamin D supplement each day was associated with an <a href="https://www.bmj.com/content/376/bmj-2021-066452">18% lower risk</a> of autoimmune disease – notably rheumatoid arthritis.</p> <p>Vitamin D supplements may also be linked with lower risk of cardiovascular disease. A <a href="https://www.bmj.com/content/381/bmj-2023-075230">major Australian study</a>, which looked at over 21,000 people aged 60-84, found that participants who took a 2,000 IU vitamin D supplement a day for five years had a lower risk of suffering a major cardiovascular event (such as stroke or heart attack) compared to those who didn’t take a supplement.</p> <p>It’s currently not known why vitamin D may have these benefits on these other areas of our health. It’s also worth noting that in many of these trials, very few of the participants were actually vitamin D deficient. While we might speculate the observed health benefits may be even greater in people with vitamin D deficiency, it will be important for future research to study these factors.</p> <p>While it’s too early to say whether vitamin D supplements have broad health benefits, it’s clear it’s beneficial for bone health. It may be worthwhile to take a supplement in the winter months, especially if you’re over 65, have darker skin or spent a lot of time indoors as these factors can put you at <a href="https://www.mayoclinic.org/healthy-lifestyle/nutrition-and-healthy-eating/expert-answers/vitamin-d-deficiency/faq-20058397#:%7E:text=However%2C%20some%20groups%20%E2%80%94%20particularly%20people,sun%20exposure%20or%20other%20factors.">increased risk of vitamin D deficiency</a>.</p> <p>The research also shows us that we should be rethinking vitamin D supplementation advice. While in the UK it’s recommended people get 400 IU of vitamin D a day, many trials have shown 2,000 IU a day is associated with health benefits.<!-- Below is The Conversation's page counter tag.

How much protein do I need as I get older? And do I need supplements to get enough?

<p><em><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>If you are a woman around 50, you might have seen advice on social media or <a href="https://www.instagram.com/p/CyVwOSzucnh">from influencers</a> telling you protein requirements increase dramatically in midlife. Such recommendations suggest a 70 kilogram woman needs around 150 grams of protein each day. That’s the equivalent of 25 boiled eggs at 6 grams of protein each.</p> <p>Can that be right? Firstly let’s have a look at what protein is and where you get it.</p> <p><a href="https://www.betterhealth.vic.gov.au/health/healthyliving/protein">Protein</a> is an essential macro-nutrient in our diet. It provides us with energy and is used to repair and make muscle, bones, soft tissues and hormones and enzymes. Mostly we associate animal foods (dairy, meat and eggs) as being rich in protein. Plant foods such as bread, grains and legumes provide valuable sources of protein too.</p> <p>But what happens to our requirements as we get older?</p> <h2>Ages and stages</h2> <p>Protein requirements change <a href="https://www.eatforhealth.gov.au/nutrient-reference-values/nutrients/protein">through different life stages</a>. This reflects changes in growth, especially from babies through to young adulthood. The estimated average requirements by age are:</p> <ul> <li> <p>1.43g protein per kg of body weight at birth</p> </li> <li> <p>1.6g per kg of body weight at 6–12 months (when protein requirements are at their highest point)</p> </li> <li> <p>protein needs decline from 0.92g down to 0.62g per kg of body weight from 6–18 years.</p> </li> </ul> <p>When we reach adulthood, protein requirements differ for men and women, which reflects the higher muscle mass in men compared to women:</p> <ul> <li> <p>0.68g per kg of body weight for men</p> </li> <li> <p>0.6g per kg of body weight for women.</p> </li> </ul> <p>Australian recommendations for people over 70 reflect the increased need for tissue repair and muscle maintenance:</p> <ul> <li> <p>0.86g per kg of bodyweight for men</p> </li> <li> <p>0.75g per kg of bodyweight for women.</p> </li> </ul> <p>For a 70kg man this is a difference of 12.6g/protein per day. For a 70kg woman this is an increase of 10.5g per day. You can add 10g of protein by consuming an extra 300ml milk, 60g cheese, 35g chicken, 140g lentils, or 3–4 slices of bread.</p> <p>There is emerging evidence <a href="https://www.scopus.com/record/display.uri?eid=2-s2.0-85124835199&amp;origin=resultslist&amp;sort=plf-f&amp;cite=2-s2.0-84881254292&amp;src=s&amp;nlo=&amp;nlr=&amp;nls=&amp;imp=t&amp;sid=c07c9e014577c86ab8cf85c62d9764cd&amp;sot=cite&amp;sdt=a&amp;sl=0&amp;relpos=39&amp;citeCnt=6&amp;searchTerm=">higher intakes</a> for people over 70 (up to 0.94–1.3g per kg of bodyweight per day) might reduce age-related decline in muscle mass (known as sarcopenia). But this must be accompanied with increased resistance-based exercise, such as using weights or stretchy bands. As yet these have not been included in any national nutrient guidelines.</p> <h2>But what about in midlife?</h2> <p>So, part of a push for higher protein in midlife might be due to wanting to prevent age-related muscle loss. And it might also be part of a common desire to prevent weight gain that may come with <a href="https://obgyn.onlinelibrary.wiley.com/doi/10.1111/1471-0528.17290?af=R">hormonal changes</a>.</p> <p>There have been relatively few studies specifically looking at protein intake in middle-aged women. One large 2017 observational study (where researchers look for patterns in a population sample) of over 85,000 middle-aged nurses found higher intake of vegetable protein – but not animal protein or total protein – was linked to a <a href="https://academic.oup.com/aje/article/187/2/270/3886033">lower incidence of early menopause</a>.</p> <p>In the same group of women another study found higher intake of vegetable protein was linked to a <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/jcsm.12972">lower risk of frailty</a> (meaning a lower risk of falls, disability, hospitalisation and death). Higher intake of animal protein was linked to higher risk of frailty, but total intake of protein had no impact.</p> <p>Another <a href="https://journals.lww.com/menopausejournal/abstract/2017/05000/skeletal_muscle_mass_is_associated_with_higher.9.aspx">smaller observational study</a> of 103 postmenopausal women found higher lean muscle mass in middle-aged women with higher protein intake. Yet an <a href="https://journals.lww.com/menopausejournal/abstract/2021/03000/effects_of_high_protein,_low_glycemic_index_diet.11.aspx">intervention study</a> (where researchers test out a specific change) showed no effect of higher protein intake on lean body mass in late post-menopasual women.</p> <p><a href="https://obgyn.onlinelibrary.wiley.com/doi/10.1111/1471-0528.17290?af=R">Some researchers</a> are theorising that higher dietary protein intake, along with a reduction in kilojoules, could reduce weight gain in menopause. But this has not been tested in clinical trials.</p> <p>Increasing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7539343/">protein intake</a>, improves satiety (feeling full), which may be responsible for reducing body weight and maintaining muscle mass. The protein intake to improve satiety in studies has been about 1.0–1.6g per kg of bodyweight per day. However such studies have not been specific to middle-aged women, but across all ages and in both men and women.</p> <h2>What are we actually eating?</h2> <p>If we look at what the <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/australian-health-survey-usual-nutrient-intakes/latest-release">average daily intake of protein is</a>, we can see 99% of Australians under the age of 70 meet their protein requirements from food. So most adults won’t need supplements.</p> <p>Only 14% of men over 70 and 4% of women over 70 do not meet their estimated average protein requirements. This could be for many reasons, including a decline in overall health or an illness or injury which leads to reduced appetite, reduced ability to prepare foods for themselves and also the cost of animal sources of protein.</p> <p>While they may benefit from increased protein from supplements, opting for a food-first approach is preferable. As well as being more familiar and delicious, it comes with other essential nutrients. For example, red meat also has iron and zinc in it, fish has omega-3 fats, and eggs have vitamin A and D, some iron and omega-3 fats and dairy has calcium.</p> <h2>So what should I do?</h2> <p>Symptoms of <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/protein#getting-too-little-protein-protein-deficiency">protein deficiency</a> include muscle wasting, poor wound healing, oedema (fluid build-up) and anaemia (when blood doesn’t provide enough oxygen to cells). But the amount of protein in the average Australian diet means deficiency is rare. The <a href="https://www.eatforhealth.gov.au/guidelines/australian-guide-healthy-eating">Australian dietary guidelines</a> provide information on the number of serves you need from each food group to achieve a balanced diet that will meet your nutrient requirements.</p> <p>If you are concerned about your protein intake due to poor health, increased demand because of the sports you’re doing or because you are a vegan or vegetarian, talk to your GP or an accredited practising dietitian.<!-- Below is The Conversation's page counter tag.

Are fish oil supplements as healthy as we think? And is eating fish better?

<p><em><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Fish oil, which contains omega-3 fatty acids, is promoted for a number of health benefits – from boosting our heart health, protecting our brain from dementia, and easing the symptoms of rheumatoid arthritis.</p> <p>But what exactly are omega-3 fats and what does the evidence say about their benefits for keeping us healthy?</p> <p>And if they <em>are</em> good for us, does eating fish provide the same benefit as supplements?</p> <h2>What are omega-3 fats?</h2> <p>Omega-3 fatty acids are a type of polyunsaturated fatty acid. They are essential to consume in our diet because we can’t make them in our body.</p> <p>Three main types of omega-3 fats are important in our diet:</p> <ul> <li> <p>alpha-linolenic acid (ALA), which is found in plant foods such as green leafy vegetables, walnuts, flaxseed and chia seeds</p> </li> <li> <p>eicosapentanoic acid (EPA), which is only found in seafood, eggs (higher in free-range rather than cage eggs) and breast milk</p> </li> <li> <p>docosahexaenoic acid (DHA) is also only found in seafood, eggs (again, higher in free-range eggs) and breast milk.</p> </li> </ul> <p>Omega 3s are key to the structure of our cells, and help keep our heart, lungs, blood vessels, and immune system working.</p> <h2>Eating fish vs taking a supplement</h2> <p>The initial studies suggesting omega-3 fats may have health benefits came from <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/j.0954-6820.1976.tb08198.x">observational studies on people eating fish</a>, not from fish oil.</p> <p>So are the “active ingredients” from supplements – the EPA and DHA – absorbed into our body in the same way as fish?</p> <p>An <a href="https://www.sciencedirect.com/science/article/pii/S0002916523281484">intervention study</a> (where one group was given fish and one group fish oil supplements) found the levels of EPA and DHA in your body increase in a similar way when you consume equal amounts of them from either fish or fish oil.</p> <p>But this assumes it is just the omega-3 fats that provide health benefits. There are other <a href="https://www.foodstandards.gov.au/science/monitoringnutrients/afcd/pages/default.aspx">components of fish</a>, such as protein, vitamins A and D, iodine, and selenium that could be wholly or jointly responsible for the health benefits.</p> <p>The health benefits seen may also be partially due to the absence of certain nutrients that would have otherwise been consumed from other types of meat (red meat and processed meat) such as saturated fats and salt.</p> <h2>So what are the benefits of omega 3 fats? And does the source matter?</h2> <p>Let’s consider the evidence for heart disease, arthritis and dementia.</p> <p><strong>Heart disease</strong></p> <p>For cardiovascular disease (heart attacks and stroke), a <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD003177.pub3/full">meta-analysis</a>, which provides the highest quality evidence, has shown fish oil supplementation probably makes little or no difference.</p> <p>Another <a href="https://www.mdpi.com/2072-6643/12/8/2278">meta-analysis</a> found for every 20 grams per day of fish consumed it reduced the risk of coronary heart disease by 4%.</p> <p>The <a href="https://www.heartfoundation.org.au/getmedia/f1d22267-7381-4513-834b-df317bed9a40/Nutrition_Position_Statement_-_DIETARY_FAT_FINAL-4.pdf">National Heart Foundation</a> recommends, based on the scientific evidence, eating fish rich in omega-3 fats for optimal heart health. <a href="https://apjcn.nhri.org.tw/server/APJCN/17/3/385.pdf">Fish vary in their omega-3 levels</a> and generally the fishier they taste the more omega-3 fats they have – such as tuna, salmon, deep sea perch, trevally, mackeral and snook.</p> <p>The foundation says fish oil may be beneficial for people with heart failure or high triglycerides, a type of fat that circulates in the blood that increases the risk of heart disease and stroke. But it doesn’t recommend fish oil for reducing the risk of cardiovascular diseases (heart attack and stroke).</p> <p><strong>Arthritis</strong></p> <p>For rheumatoid arthritis, <a href="https://arthritis-research.biomedcentral.com/articles/10.1186/s13075-022-02781-2">studies</a> have shown fish oil supplements do provide benefits in reducing the severity and the progression of the disease.</p> <p>Eating fish also leads to these improvements, but as the level of EPA and DHA needed is high, often it’s difficult and expensive to consume that amount from fish alone.</p> <p><a href="https://arthritisaustralia.com.au/managing-arthritis/living-with-arthritis/complementary-treatments-and-therapies/fish-oils/">Arthritis Australia</a> recommends, based on the evidence, about 2.7 grams of EPA and DHA a day to reduce joint inflammation. Most supplements contain about 300-400mg of omega-3 fats.</p> <p>So depending on how much EPA and DHA is in each capsule, you may need nine to 14 capsules (or five to seven capsules of fish oil concentrate) a day. This is about 130g-140g of grilled salmon or mackeral, or 350g of canned tuna in brine (almost four small tins).</p> <p><strong>Dementia</strong></p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0952327807001421?via%3Dihub">Epidemiological studies</a> have shown a positive link between an increased DHA intake (from diet) and a lower risk of developing Alzheimer’s disease, a type of dementia.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0952327807001421?via%3Dihub">Animal studies</a> have shown DHA can alter markers that are used to assess brain function (such as accumulation of amyloid – a protein thought to be linked to dementia, and damage to tau protein, which helps stabilise nerve cells in the brain). But this hasn’t been shown in humans yet.</p> <p>A systematic review of <a href="http://betamedarts.gr/wp-content/uploads/2021/05/31Psychiatriki03_2020.pdf#page=58">multiple studies in people</a> has shown different results for omega-3 fats from supplements.</p> <p>In the two studies that gave omega-3 fats as supplements to people with dementia, there was no improvement. But when given to people with mild cognitive impairment, a condition associated with increased risk of progressing to dementia, there was an improvement.</p> <p>Another <a href="https://pubmed.ncbi.nlm.nih.gov/25446949/">meta-anlayses</a> (a study of studies) showed a higher intake of fish was linked to lower risk of Alzheimers, but this relationship was not observed with total dietary intake of omega-3 fats. This indicates there may be other protective benefits derived from eating fish.</p> <p>In line with the evidence, the <a href="https://www.alzheimers.org.uk/about-dementia/risk-factors-and-prevention/omega-3-and-dementia#:%7E:text=This%20could%20suggest%20that%20taking,its%20own%20may%20not%20be.">Alzheimer’s Society</a> recommends eating fish over taking fish oil supplements.</p> <h2>So what’s the bottom line?</h2> <p>The more people stick to a healthy, plant-based diet with fish and minimal intakes of ultra-processed foods, the better their health will be.</p> <p>At the moment, the evidence suggests fish oil is beneficial for rheumatoid arthritis, particularly if people find it difficult to eat large amounts of fish.</p> <p>For dementia and heart disease, it’s best to try to eat your omega-3 fats from your diet. While plant foods contain ALA, this will not be as efficient as increasing EPA and DHA levels in your body by eating seafood.</p> <p>Like any product that sits on the shop shelves, check the use-by date of the fish oil and make sure you will be able to consume it all by then. The chemical structure of EPA and DHA makes <a href="https://www.sciencedirect.com/science/article/pii/S0924224421005422">it susceptible to degradation</a>, which affects its nutritional value. Store it in cold conditions, preferably in the fridge, away from light.</p> <p>Fish oil can have some annoying side effects, such as fishy burps, but generally there are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3664575/">minimal serious side effects</a>. However, it’s important to discuss taking fish oil with all your treating doctors, particularly if you’re on other medication.<!-- Below is The Conversation's page counter tag.

How can I lower my cholesterol? Do supplements work? How about psyllium or probiotics?

<p><em><a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a></em></p> <p>Your GP says you have high cholesterol. You’ve six months to work on your diet to see if that’ll bring down your levels, then you’ll review your options.</p> <p>Could taking supplements over this time help?</p> <p>You can’t rely on supplements alone to control your cholesterol. But there’s some good evidence that taking particular supplements, while also eating a healthy diet, can make a difference.</p> <h2>Why are we so worried about cholesterol?</h2> <p>There are two main types of cholesterol, both affecting your risk of heart disease and stroke. Both types are carried in the bloodstream inside molecules called lipoproteins.</p> <p><strong>Low-density lipoprotein or LDL cholesterol</strong></p> <p>This is often called “bad” cholesterol. This lipoprotein carries cholesterol from the liver to cells throughout the body. High levels of LDL cholesterol in the blood can lead to the <a href="https://www.ahajournals.org/doi/full/10.1161/JAHA.118.011433">build-up of plaque</a> in arteries, which leads to an <em>increased</em> risk of heart disease and stroke.</p> <p><strong>High-density lipoprotein or HDL cholesterol</strong></p> <p>This is often called “good” cholesterol. This lipoprotein helps remove excess cholesterol from the bloodstream and transports it back to the liver for processing and excretion. Higher levels of HDL cholesterol are <a href="https://www.ahajournals.org/doi/full/10.1161/CIRCRESAHA.119.312617">linked to</a> a <em>reduced</em> risk of heart disease and stroke.</p> <p>Diet can play a key role in reducing blood cholesterol levels, especially LDL (“bad”) cholesterol. Healthy dietary choices are <a href="https://theconversation.com/got-high-cholesterol-here-are-five-foods-to-eat-and-avoid-63941">well recognised</a>. These include a focus on eating more unsaturated (“healthy”) fat (such as from olive oil or avocado), and eating less saturated (“unhealthy”) fat (such as animal fats) and trans fats (found in some shop-bought biscuits, pies and pizza bases).</p> <h2>Fibre is your friend</h2> <p>An additional way to significantly reduce your total cholesterol and LDL cholesterol levels through diet is by eating more <a href="https://theconversation.com/fiber-is-your-bodys-natural-guide-to-weight-management-rather-than-cutting-carbs-out-of-your-diet-eat-them-in-their-original-fiber-packaging-instead-205159">soluble fibre</a>.</p> <p>This is a type of fibre that dissolves in water to form a gel-like substance in your gut. The gel can bind to cholesterol molecules preventing them from being absorbed into the bloodstream and allows them to be eliminated from the body through your faeces.</p> <p>You can find soluble fibre in whole foods such as fruits, vegetables, oats, barley, beans and lentils.</p> <h2>Fibre supplements, such as psyllium</h2> <p>There are also many fibre supplements and food-based products on the market that may help lower cholesterol. These include:</p> <ul> <li> <p><strong>natural soluble fibres</strong>, such as inulin (for example, Benefiber) or psyllium (for example, Metamucil) or beta-glucan (for example, in ground oats)</p> </li> <li> <p><strong>synthetic soluble fibres</strong>, such as polydextrose (for example, STA-LITE), wheat dextrin (also found in Benefiber) or methylcellulose (such as Citrucel)</p> </li> <li> <p><strong>natural insoluble fibres</strong>, which bulk out your faeces, such as flax seeds.</p> </li> </ul> <p>Most of these supplements come as fibres you add to food or dissolve in water or drinks.</p> <p>Psyllium is the fibre supplement with the strongest evidence to support its use in improving cholesterol levels. It’s been <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5413815/">studied</a> in at least 24 high-quality randomised controlled trials.</p> <p>These trials show consuming about 10g of psyllium a day (1 tablespoon), as part of a healthy diet, <a href="https://www.sciencedirect.com/science/article/pii/S0002916523070107#:%7E:text=Conclusions%3A,mild%2Dto%2Dmoderate%20hypercholesterolemia.">can significantly lower</a> total cholesterol levels by 4% and LDL cholesterol levels by 7%.</p> <h2>Probiotics</h2> <p>Other cholesterol-lowering supplements, such as probiotics, are not based on fibre. Probiotics are thought to help lower cholesterol levels via a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3352670/">number of mechanisms</a>. These include helping to incorporate cholesterol into cells, and adjusting the microbiome of the gut to favour elimination of cholesterol via the faeces.</p> <p>Using probiotics to reduce cholesterol is an upcoming area of interest and the <a href="https://www.sciencedirect.com/science/article/abs/pii/S089990071500461X">research</a> is promising.</p> <p>In a <a href="https://pubmed.ncbi.nlm.nih.gov/29384846/">2018 study</a>, researchers pooled results from 32 studies and analysed them altogether in a type of study known as a meta-analysis. The people who took probiotics reduced their total cholesterol level by 13%.</p> <p><a href="https://www.tandfonline.com/doi/full/10.3109/07853890.2015.1071872">Other</a> <a href="https://link.springer.com/article/10.1007/s11906-020-01080-y">systematic reviews</a> support these findings.</p> <p>Most of these studies use probiotics containing <em>Lactobacillus acidophilus</em> and <em>Bifidobacterium lactis</em>, which come in capsules or powders and are consumed daily.</p> <p>Ultimately, probiotics could be worth a try. However, the effects will likely vary according to the probiotic strains used, whether you take the probiotic each day as indicated, as well as your health status and your diet.</p> <h2>Red yeast rice</h2> <p><a href="https://www.nccih.nih.gov/health/red-yeast-rice">Red yeast rice</a> is another non-fibre supplement that has gained attention for lowering cholesterol. It is often used in Asia and some European countries as a complementary therapy. It comes in capsule form and is thought to mimic the role of the cholesterol-lowering medications known as statins.</p> <p>A <a href="https://www.frontiersin.org/articles/10.3389/fphar.2021.819482/full">2022 systematic review</a> analysed data from 15 randomised controlled trials. It found taking red yeast rice supplements (200-4,800mg a day) was more effective for lowering blood fats known as triglycerides but less effective at lowering total cholesterol compared with statins.</p> <p>However, these trials don’t tell us if red yeast rice works and is safe in the long term. The authors also said only one study in the review was registered in a major <a href="https://www.clinicaltrials.gov">database</a> of clinical trials. So we don’t know if the evidence base was complete or biased to only publish studies with positive results.</p> <h2>Diet and supplements may not be enough</h2> <p>Always speak to your GP and dietitian about your plan to take supplements to lower your cholesterol.</p> <p>But remember, dietary changes alone – with or without supplements – might not be enough to lower your cholesterol levels sufficiently. You still need to quit smoking, reduce stress, exercise regularly and get enough sleep. Genetics can also play a role.</p> <p>Even then, depending on your cholesterol levels and other risk factors, you may still be recommended cholesterol-lowering medications, such as <a href="https://jamanetwork.com/journals/jama/fullarticle/2795522">statins</a>. Your GP will discuss your options at your six-month review.<!-- Below is The Conversation's page counter tag.

Why you may need supplements

<p>While most of us look well-nourished in the western world, the reality tells a very different story.</p> <p>At least 55 per cent of Aussies have some form of nutrient deficiency, commonly caused by poor food choices, poor lifestyle choices, medications, poor quality ingredients, over-farmed soil, eating out of season and even from cold storage.</p> <p>Your body will share essential vitamins, minerals and fatty acids on a day-to-day basis to meet your immediate and fluctuating needs. While taking supplements is no replacement for a poor diet, as the name suggests, they may ‘supplement’ a healthy, balanced diet.</p> <p>Poor nutrition has been linked to an increased risk of many diseases, including cancer, heart disease, and diabetes.</p> <p>The human diet requires both macro-nutrients, which are the main source of energy, and micro-nutrients, required for all metabolic processes.</p> <p>Unfortunately, the most abundant source of dietary fuel in the Western diet is nutrient-poor, refined carbohydrates, which explains how most of the population are overweight and undernourished.</p> <p>Restrictive diets such as veganism can also lead to nutrient deficiencies. Animal and plant foods are complimentary, so for optimal nourishment, we need them both.  While some deficiencies can be mild, others can cause a lifelong impact.</p> <p>Some common deficiencies:</p> <p>- <strong>Vitamin B12</strong>. This deficiency is particularly common in aged care facilities where about 14 per cent of patients are low in Vitamin B12. It affects memory, balance, fatigue and usually goes hand in hand with iron deficiency.</p> <p>- <strong>Calcium</strong>. This deficiency can be caused by a lack of Vitamin D, and you may not have any symptoms other than muscle weakness and spasms, fatigue or pins and needles. It’s difficult to eat adequate calcium in the diet, needing 1300mg a day over the age of 50. One cup of milk provides only 300mg.</p> <p>- <strong>Iodine</strong>. Australia has very low iodine levels but it’s a crucial mineral to support thyroid function. It can cause constipation, fatigue and weight gain.</p> <p>- <strong>Vitamin D</strong>. More than a third of Australians have a severe deficiency. It plays a huge role in immunity, lowering in winter because we don’t get as much sun. A lack of Vitamin D causes weakened bones, muscle pain and weakness.</p> <p>- <strong>Zinc</strong>. 85 per cent of Australian women and 50 per cent of men don’t eat enough zinc. Oysters are the best source, along with seaweed. It’s crucial for supporting immunity and deficiency can cause hair loss, diarrhea, impotence, skin, and vision problems.</p> <p>- <strong>Magnesium</strong>. 85-95 per cent of people are deficient which can lead to osteoporosis, heart disease, muscle weakness, shakiness, cramps, sleeplessness, abnormal heart rhythm and migraine.</p> <p>You can discover if your body has a low level of these nutrients through a simple blood test when you next visit your doctor, who can advise whether you need a dietary supplement.</p> <p>As we get older, we may need to a little more help to keep our body running well, so remember, knowledge is power!</p> <p><em>This article was written by Donna Aston.

COVID concerns drive supplement and vitamin use

<div> <p><em>Image: Getty </em></p> <p><span>Sales of complementary medicines have been driven up by COVID fears, but immune boosting claims for them are doing more harm than good. </span></p> <div class="copy"> <p>In an <a rel="noopener" href="https://www.nps.org.au/australian-prescriber/articles/the-safety-of-commonly-used-vitamins-and-minerals" target="_blank">article</a> published today in <em>Australian Prescriber, </em>University of Queensland Adjunct Associate Professor of Pharmacology Geraldine Moses has warned of major potential harms associated with the use of dietary supplements.</p> <p>“One reason for the persistent popularity of vitamins and minerals is the perception that they are harmless,” says Moses. But that perception masks a troublesome reality.</p> <p>“When it comes to complementary medicines, most consumers are only given information about the possible benefits of these products, and little if anything about risk – and there’s always potential risk.”</p> <p>The advice comes as supplement use is soaring. In July, a US survey claimed that nearly 30% of Americans are now taking more supplements than they were before the COVID-19 pandemic. Commissioned by the US health non-profit <a rel="noopener" href="https://www.samueli.org/" target="_blank">Samueli Foundation</a>, the <a rel="noopener" href="https://theharrispoll.com/" target="_blank">Harris Poll</a> concluded that 76% of US citizens were taking supplements.</p> <p>The article in <em>Australian Prescriber</em> discusses six potential harms of using dietary supplements:</p> <ul> <li>They can have <strong>adverse effects</strong>, particularly at high doses.</li> <li>They can <strong>interact with other medicines</strong>.</li> <li>They <strong>cost money</strong>, which may be better spent on other things.</li> <li>Time spent taking dietary supplements may delay <strong>more effective treatments</strong>.</li> <li>They may <strong>bring false hope</strong> and disappointment.</li> <li>By taking dietary supplements, people <strong>add to the number of medicines they are taking</strong>, increasing the risk of medication error, interactions and adverse effects.</li> </ul> <p>The US survey was small and not based on a probability sample, so more research is required to build an accurate picture. But the trend it highlights is supported by evidence globally of an upturn in supplement use.</p> <p>Accurate figures for Australia are hard to obtain, but market researchers <a rel="noopener" href="https://www.ibisworld.com/au/industry/online-vitamin-supplement-sales/4091/" target="_blank">report</a> that sales of vitamins and supplements soared during the pandemic. </p> <p>The trend suggests that pandemic-related fear may be driving the use of these products, which some experts say are not regulated or evidenced as rigorously as <a rel="noopener" href="https://www.tga.gov.au/registered-medicines" target="_blank">registered medicines</a>. And while the pandemic may have bolstered supplement sales, the scale of their use has always been profound: in 2018, around <a rel="noopener" href="http://www.roymorgan.com/findings/7956-australian-vitamin-market-december-2018-201904260734" target="_blank">a third of Australians</a> – 8.3 million people – reported buying supplements, according to Roy Morgan.</p> <h4><strong>Supplementary harms?</strong></h4> <p>Supplements can be benign and are critical for people with particular conditions or deficiencies, but there are notable cases in which they’ve been shown to cause long-term damage.</p> <p>Just last week, doctors at a Sydney liver transplant centre <a rel="noopener" href="https://insightplus.mja.com.au/2021/27/drug-related-liver-injury-call-for-better-regulation-of-supplements/" target="_blank">went public with concerns</a> that drug-induced liver injuries linked to dietary and herbal supplements were on the rise. </p> <p>Their <a rel="noopener" href="https://www.mja.com.au/journal/2021/215/6/drug-induced-liver-injury-australia-2009-2020-increasing-proportion-non" target="_blank">study</a>, which spanned 2009 to 2020, found that the proportion of drug-induced liver injuries that were caused by supplements (as opposed to things such as paracetamol and other medications) rose from 15% in 2009–11 to 47% in 2018–20. </p> <p>“We observed a link to bodybuilding and weight-loss supplements as has been seen in reports internationally, but also a link to traditional Chinese medicines,” says co-author Simone Strasser, president of the Gastroenterological Society. “Both groups of supplements are rising in popularity in Australia.”</p> <p>Strasser says that in many cases supplement-related drug-induced liver injuries (DILIs) were potentially severe: while 90-day transplant-free survival was 74% for liver injuries caused by paracetamol, it was 59% for those caused by supplements. </p> <p>“There’s an old saying that the difference between a drug and a poison is the dose,” says Moses. “What many people don’t realise is that high doses of some supplements can be dangerous.”</p> <p>Moses says that because consumers aren’t aware of the potential toxicity of supplements, they may be skirting perilously close to the line without even knowing.</p> <p>“Vitamin B6 is the classic one,” Moses says. “In Australia, the toxic dose is considered to be 200mg a day or more, and lots of people that I see now in hospital will be on four products with 50mg in each one, so they’re at the toxic dose, but they’re completely unaware of that.”</p> <p>The authors of the liver-damage study have expressed concern that so many supplements are escaping regulatory oversight by the Therapeutic Goods Administration (TGA), not least, Strasser says, because “not infrequently these compounds were purchased online, bypassing the Australian regulatory system”.</p> <p>Strasser adds that because reporting adverse events associated with supplements to the TGA is voluntary, many severe adverse reactions go unreported.</p> <h4><strong>Health anxiety drives demand</strong></h4> <p>As the pandemic progresses, reports of health anxiety <a rel="noopener" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7239023/" target="_blank">naturally rise</a>. A July 2020 <a rel="noopener" href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0236562" target="_blank">study</a> among 5,070 adult Australians of varying ages and from various locations found that 25% were very or extremely worried about contracting COVID-19, and around half (52%) were worried about family and friends contracting the disease.</p> <p>“When people are fearful, especially now with COVID, they will reach out and do whatever they can to assuage their anxiety, including taking natural health products,” Moses says. </p> <div class="newsletter-box"> <p class="h2"><strong>But do supplements work as promised?</strong></p> </div> <p>Ken Harvey, a professor at Bond University’s school of Health Sciences and Medicine and an outspoken critic of pharmaceutical marketing, says that supplements can be helpful in specific cases. For example, pregnant women are encouraged to take folic acid to reduce the risk of foetal defects, and older people may need certain nutritional supplements to make up for deficiencies caused by poor diet, lack of activity and a lack of sunlight. </p> <p>But Harvey says most Australians can get enough of what they need from a reasonably healthy diet, so any vitamin they take will simply be filtered out by the kidneys and excreted in urine, because the body already has enough. </p> <p>Meanwhile, social media and wellness ‘influencers’ are patently contributing to the problem. A 2020 <a rel="noopener" href="https://aacijournal.biomedcentral.com/articles/10.1186/s13223-020-00474-6" target="_blank">study</a> in <em>BMC Allergy, Ashthma and Clinical Immunology </em>found that use of the popular Instagram hashtag #immunebooster increased by over 46% between 15 April and 15 May 2020.</p> <h4><strong>The myth of “immune-boosting” products</strong></h4> <p>One of the most touted phrases by both wellness influencers and supplement brands is ‘immune-boosting’, a term that had become synonymous with “wellness” even before the global pandemic. But how accurate is the term ‘immune-boosting’?</p> <p>Well, not very. According to Harvey, the immune-boosting myth is based on the fact that a lack of vitamins and minerals is known to<em> </em>weaken immunity, for example among malnourished populations. But Harvey says that in Australia, “there is no good evidence of widespread vitamin deficiencies in the population”.</p> <p>In fact, the idea of immune-boosting is based on a misconception about how the immune system works. The immune system is <a rel="noopener" href="https://www.cedars-sinai.org/blog/boosting-your-immune-system.html" target="_blank">better off balanced</a> than boosted – if it could be boosted by supplements (<a rel="noopener" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6673706/#B7" target="_blank">which it can’t</a>), users would experience symptoms of an immune response, such as fever and a runny nose, and in extreme cases would end up very sick.</p> <p>“To ‘boost’ your immune system against specific diseases, you’ve got to either catch one, or you’ve got to be vaccinated,” Harvey says, adding that consumers often buy supplements under the mistaken belief – promoted by some brands – that they will offer immunological benefits.</p> <p>Even more alarming, there is <a rel="noopener" href="https://pubmed.ncbi.nlm.nih.gov/28911953/" target="_blank">evidence</a> that some people may use ‘immune-boosting’ natural remedies as an alternative to vaccinations against viral conditions such as the flu, meaning the immune-boosting myth could hamper the fight against disease.</p> <p>Harvey says the TGA has regulated against advertising that promotes immune-boosting products by reference to the pandemic – but there’s a major loophole, because products can still be marketed as ‘immune-boosting’, provided they don’t mention COVID-19. </p> <h4><strong>So, how <em>are</em> supplements regulated?</strong></h4> <p>Under the TGA’s classification process, there are two major categories of medicines. Registered medicines include all prescription medications and most over-the-counter (OTC) medicines. Prescription medications are considered higher risk, and OTC medicines a lower but still palpable risk, so all registered medicines are assessed by the TGA for quality, safety <em>and </em>efficacy.</p> <p>Efficacy, in pharmacological terms, refers to the ability of a drug to provide the benefits to which it claims, including establishing the dosage required to provide that benefit. <a rel="noopener" href="https://www.nps.org.au/australian-prescriber/articles/efficacy-effectiveness-efficiency" target="_blank">Efficacy is established during clinical trials</a>.</p> <p>Complementary medicines such as supplements fall into the category of <a rel="noopener" href="https://www.tga.gov.au/listed-medicines" target="_blank">listed medicines</a>, which generally contain well-known, low-risk ingredients with long histories of use, such as vitamin and mineral products and sunscreens. These medicines are those that the TGA considers to be generally benign or low risk, so, “listed medicines do not undergo a full pre-market assessment of safety, quality and efficacy,” according to the TGA.</p> <p>The TGA <em>does</em> do yearly post-marketing surveillance on around 150 of the thousands of listed medicines on the Australian market, the results of which can be found in its <a rel="noopener" href="https://www.tga.gov.au/annual-performance-statistics-reports" target="_blank">annual performance statistics reports</a>. </p> <p>A review of the performance statistics over the five years from 2015 to 2020 reveals that around 75% to 80% of the listed medicines tested are found to breach compliance in some way, which would appear to point to what Harvey refers to as a “light-touch regulatory process” for listed medicines.</p> <h4><strong>Where to now?</strong></h4> <p>Approached for comment, the TGA informed <em>Cosmos </em>that enhancements to the listed medicines post-market compliance scheme are coming. </p> <p>But the supplement sector has always been resilient, offering an alluring alternative to Western medicine, whether because the supplements are perceived as low risk, or because of an inherent distrust of public-health messaging.</p> <p>“They [the TGA] have a pretty tough job to do, trying to cover every possible pharmaceutical product throughout Australia,” Moses says. “But I certainly think that with complementary medicines we could do a better job if we required manufacturers to provide consumers with information about potential risks.”</p> <p>Strasser says that a lack of public education is hampering both the TGA and the medical profession’s ability to clamp down on unsafe supplement use.</p> <p>“There is still a perception that supplements are natural and therefore healthy,” she says. “Time after time, patients who experience severe DILI are incredibly surprised that something they purchase over the counter or online with the aim of improving their health could have harmed them.”</p> <!-- Start of tracking content syndication.

Six immunity and healthy ageing benefits of taking a daily arctic cod liver oil supplement

<div id="primary" class="contentAreaLeft"> <div class="Maincontent"> <p><strong>Cod liver oil has been used for centuries in Scandinavian societies to help people, young and old, stay healthy throughout the year.</strong></p> <p>Fresh cod liver oil is an excellent source of the omega-3 fatty acids EPA and DHA. Unlike most fish oil products, cod liver oil is unique in that it naturally contains a higher ratio of DHA to EPA, and typically delivers omega-3s in the triglyceride molecular form, the best form for their absorption by the body. Both EPA and DHA play vital roles in aspects of healthy ageing and immune function by influencing muscle and bone mass, mobility, energy, immune responses, and cognitive performance.</p> <p>Ensuring adequate intake of omega-3s with cod liver oil is an easy lifestyle change that can have a positive effect on many aspects of health. Here are some of the most notable omega-3 benefits of cod liver oil (a.k.a. CLO).</p> <p><strong>1. Omega-3s in CLO can support immune health via the gut</strong></p> <p>Having an overabundance of unhealthy gut bacteria can impair the immune system and accelerate the ageing process. Diet and lifestyle choices—including omega-3 consumption—are key factors for helping to establish a favourable environment for beneficial gut bacteria. Some studies have shown that increased consumption of omega-3s helps promote the growth of “good bacteria” in your gut, while other studies have shown a positive connection between adequate amounts of beneficial gut bacteria and a healthier immune response.</p> <p><strong>2. Omega-3 intake may influence muscle and bone strength</strong></p> <p>As we age, our immune system produces higher blood levels of inflammatory proteins that may impair muscle and bone health. Omega-3s supplements may support healthier blood levels of these age-associated proteins. Several studies report that people with higher dietary intake of omega-3s tend to have stronger muscles, increased exercise capacity, and denser bones. So consider a cod liver oil (especially one with vitamin D) for musculoskeletal health.</p> <p><strong>3. Omega-3s may help counter the effects of stress</strong></p> <p>Chronic stress increases the hormone cortisol, which can negatively impact immune health, especially if it remains elevated over a period of time. Some research studies have shown that omega-3 supplements may reduce the body’s production of cortisol. Furthermore, people who are “stressed out” tend to already have lower blood levels of the omega-3s EPA and DHA, potentially making it even more important for these individuals to consume supplemental omega-3s in order to keep from getting sick.</p> <p><strong>4. Omega-3s in CLO provide the building blocks for lasting, healthy skin</strong></p> <p>The skin is the largest organ in the body that also contains significant amounts of omega-3s. Due to years of exposure to ultraviolet light, toxins, and various irritants, the skin requires nutrients like omega-3s to help counter these stresses at the cellular level. The skin barrier is an important structure that protects the body and helps maintain a youthful appearance. Adequate intake of omega-3s supports skin cell functions, promotes the skin barrier, and increases the skin’s ability to retain water—a primary component of healthy skin. Because a portion of the omega-3s we consume eventually makes its way into the skin, these essential fats are vital for skin health.</p> <p><strong>5. Omega-3s in CLO support cardiovascular health</strong></p> <p>As we age, blood vessels stiffen, and blood pressure tends to increase, which places additional stress on the heart. Studies suggest that diets rich in omega-3s support healthy blood vessels, and several have reported that omega-3 supplements promote positive blood vessel health scores. Additionally, preliminary research suggests that omega-3 fatty acids may also help reduce oxidative stress within the blood vessels, promoting an optimal environment for the vasculature.</p> <p><strong>6. Higher intake of omega-3s is beneficial for eye moisture</strong></p> <p>People with higher dietary intake of omega-3s are less likely to experience symptoms of dry eyes, and they also tend to have healthier eye glands. Research has shown that omega-3 supplements can help stimulate the tear gland’s production of fatty oils on the eye surface. As ageing, and the use of digital devices like phones, tablets, and computers remain primary risk factors for eye dryness, consuming adequate amounts of omega-3s is a smart investment in long-term eye health.</p> <p><strong>Choosing the right cod liver oil</strong></p> <p>It’s a good idea to select a CLO product that’s from wild-caught sustainable cod, and that does not contain synthetic additives. Arctic Cod Liver Oil products are a good choice. Sustainable species like Arctic cod have several advantages. Arctic cod from Norway are often sourced using small boats owned and operated by independent cod fishermen, so demand for Arctic cod supports local fishing communities. Also, these boats leave and return daily which means they have a much shorter transport time from catch to processing than larger trawling vessels. This short time helps maximise fish oil freshness, and the efficacy of the omega-3 fats in Arctic Cod Liver Oil.</p> <p>By Warren Maginn, BHSc. (Nutr. Med.), GradCert. (Hum. Nutr.)<br /><em>Functional Nutritional Medicine Practitioner and Educator</em></p> <hr /> <p><strong>Nordic Naturals Arctic Cod Liver Oil™ is made from 100% wild Arctic cod. Unlike other “cod liver oils” on the market, no fish body oils or synthetic vitamins or additives are ever used.</strong></p> <p>Nordic Naturals award-winning Arctic Cod Liver Oil™ is made exclusively from wild Arctic cod, and is an ideal choice to help boost immune system health during the colder months. Vertically integrated from catch to finished product, Arctic Cod Liver Oil far surpasses the strict European Pharmacopoeia Standard for fish oil purity and freshness.

How losing energy as you age impacts your mind and body

<p>If you’ve lost the spring in your step as of late, don’t blame your diet or your sleeping habits, but your cells.</p> <p>As you get older, both your genetics and your environment cause change to happen at a cellular level that can impact your health.</p> <p>These changes result in your muscles losing mass and strength, your skin losing elasticity and your immune system not having the resources to fight off infections like it once did.</p> <p>As well as the noticeable physical changes, there are also major changes occurring at the cellular level that aren’t as obvious.</p> <p>Nicotinamide adenine dinucleotide (NAD+) is the critical coenzyme that enables the mitochondria, which is the energy powerhouse of the cell, to produce energy that sustains all of our bodily functions.</p> <p><img style="width: 407px; height: 407px; display: block; margin-left: auto; margin-right: auto;" src="https://oversixtydev.blob.core.windows.net/media/7836151/mitochondria.jpg" alt="" data-udi="umb://media/47884a1046b94ecfb1a8827a5b4fd533" /></p> <p style="text-align: center;"><em>Mitochondria, the energy powerhouse of the cell</em></p> <p>This coenzyme plays a crucial role in co-ordinating many important cell functions, such as converting food into energy and co-ordinating cellular function, repair and regeneration.</p> <p>NAD+ is said to be the little molecule that holds the key to maintaining health on a cellular level, but this coenzyme can drop by as much as 50 per cent by the time you reach your 60s, despite being plentiful in your youth.</p> <p>Many scientists believe that maintaining healthy NAD+ levels is a key part of supporting our “health span”, which is a relatively new term that describes the amount of time we spend in good health during our lifespan.</p> <p><strong>What causes my NAD+ levels to decline?</strong></p> <p>Even if you were young and in relatively good health, your NAD+ stores can be depleted any time your body is placed under excessive metabolic stress.</p> <p>Along with ageing, some of the biggest causes of NAD+ depletion are overeating, drinking too much alcohol, not getting enough sleep, leading a sedentary lifestyle and getting sick.</p> <p>NAD+ levels can impact the way you feel, the way you look and the way you act as all of your cells are dependent on NAD+ to function properly.</p> <p><strong>How to restore NAD+ levels</strong></p> <p>If you’re wanting to support your resiliency and health as you age, there are ways you can boost your NAD+ levels through exercising, intermittent fasting or taking an NAD+ boosting supplement.</p> <p>Dr Charles Brenner, professor of biochemistry and director of the Obesity Initiative at the University of Iowa, made an important breakthrough in the field of NAD+ metabolism in 2004 after he unexpectedly discovered a new use for a rare form of vitamin B3 known as nicotinamide riboside (NR).</p> <p>“I was working on an enzyme that makes NAD in yeast,” Professor Brenner tells Over60.</p> <p>“NAD+ is a coenzyme that is the central regulator of metabolism in all forms of life. Received wisdom said that there would be no way to make NAD+ if we knocked out this enzyme, but I found that NR could bypass the known pathways to NAD+ in yeast – and I found the NR kinase genes that perform the first step in converting NR to NAD in yeast, mice and humans.</p> <p>“NR was a known compound, but it was not previously known to be a vitamin for humans until I found this pathway in 2004.”</p> <p>Brenner found that NR raised NAD+ levels by converting NR to NAD+ if taken orally and was able to boost the level of NAD+ within cells.</p> <p>“NAD+ is consumed in conditions of metabolic stress,” explains Professor Brenner, “and NR is the most effective NAD+ precursor to restore healthful NAD+ levels.”</p> <p><strong>How Tru Niagen® helps</strong></p> <p>Tru Niagen® is the branded dietary supplement containing the rare form of vitamin B3, nicotinomide riboside (NR) which has been proven to boost NAD+ levels in humans.</p> <p><img style="width: 0px; height: 0px;" src="https://oversixtydev.blob.core.windows.net/media/7836142/body-tru.jpg" alt="" data-udi="umb://media/721477a0075c4a0b876072f8d0be678d" /></p> <p>“We need NAD+ to power our bodies, but we also need NAD+ to deal with all of these common metabolic stresses. When NAD+ is committed to these defensive processes, less NAD+ coenzymes are available to convert our fuel into energy and to catalyse all of our bodily functions.”</p> <p>Australia is one of the first countries in the world to have access to the cutting-edge dietary supplement Tru Niagen® which can support energy levels, cellular repair and general health by boosting NAD+ levels.</p> <p>For more information about Tru Niagen® which was launched in Australia in April 2020, visit <strong><a rel="noopener" href="http://www.truniagen.com.au" target="_blank">www.truniagen.com.au</a></strong></p> <p><strong><em>This is a sponsored post produced in partnership with <a rel="noopener" href="https://www.truniagen.com.au/" target="_blank">Tru Niagen®</a>.</em></strong></p>

Coronavirus supplement: your guide to the Australian payments that will go to the extra million on welfare

<p>On Sunday, the government announced a <a href="https://treasury.gov.au/coronavirus">second</a> coronavirus economic package.</p> <p>In addition to further one-off payments, the package includes some of the most significant changes to social security payments Australia has ever seen, even if only on a temporary basis.</p> <p>The <a href="https://twitter.com/AlboMP/status/1242242080400793600">amendments</a> passed by parliament on Monday night expand them further.</p> <p>The package effectively doubles rates of JobSeeker Payment for most people without children.</p> <p>The maximum rate for a single recipient without dependants is currently A$565.70 per fortnight. Lone parents and those over 60 who have been on benefit for nine months or more currently get more, while members of couples each get somewhat less.</p> <p>For the six months from April 27 the government will boost it by A$550 per fortnight through a special time-limited <a href="https://treasury.gov.au/sites/default/files/2020-03/Fact_sheet-Income_Support_for_Individuals.pdf">Coronavirus Supplement</a>.</p> <p>Importantly, the extra $550 will go to all current recipients, including those who get less than $565.70 because they have assets or are in part-time work.</p> <p>It will also go to both existing and new recipients of the Youth Allowance JobSeeker Payment, Parenting Payment, Farm Household Allowance and Special Benefit.</p> <p>Thanks to Monday night’s <a href="https://www.smh.com.au/politics/federal/federal-parliament-passes-coronavirus-economic-stimulus-package-20200323-p54d73.html">amendments</a>, it will now also go to <a href="https://www.anneruston.com.au/supporting_students_through_the_effects_of_coronavirus">full-time students receiving Abstudy, Austudy and Youth Allowance for Students</a>.</p> <p>There are also <a href="https://www.theaustralian.com.au/nation/politics/coronavirus-stranded-visa-hold%20ers-thrown-welfare-lifeline-and-extended-stay/news-story/5697ef9768c61255afa9330adcb10994">reports</a> that special payments (and the Coronavirus Supplement) will be made available to temporary visa holders who lose their jobs or suffer significant financial hardship because of the coronavirus.</p> <p>In addition, the government will no longer need legislation to make further changes to settings, giving the Social Services minister unprecedented powers.</p> <p>This will give the government the ability to respond flexibly as circumstances change.</p> <p><strong>One million now, an extra million soon</strong></p> <p>Roughly 1.3 million existing recipients will receive the supplement, including the 200,000 or so students added on Monday.</p> <p>To them will be added as many as <a href="https://www.aph.gov.au/Parliamentary_Business/Hansard/Hansard_Display?bid=chamber/hansardr/bead2837-76c9-4ce9-952b-eafe8e2d614f/&amp;sid=0045">one million more</a>, who are not currently receiving the JobSeeker or any other payment.</p> <p>Among them will be permanent employees who are stood down or lose their jobs, sole traders, the self-employed, casual workers and contract workers who find themselves meeting the benefit income tests as a result of the coronavirus.</p> <p>Included are people required to care for people who are affected by the coronavirus.</p> <p><strong>Accelerated processing</strong></p> <p>The assets test for JobSeeker Payment, Youth Allowance Jobseeker and Parenting Payment will be waived for the duration of the Coronavirus Supplement.</p> <p>In addition, the normal one week waiting period will be waived, as will the liquid assets test waiting period (which can be up to 13 weeks).</p> <p>People already in this waiting period will be given immediate access to payments.</p> <p>It is also important that the Coronavirus Supplement will be paid automatically. Current recipients will receive the full $550 on top of their regular payment without asking for it.</p> <p>Services Australia is putting on an extra 5,000 staff to deal with the inflow of new claimants and <a href="https://treasury.gov.au/sites/default/files/2020-03/Fact_sheet-Income_Support_for_Individuals.pdf">accelerating claim process</a>.</p> <p><strong>Australia moves up the ranks</strong></p> <p>These changes will significantly boost the adequacy of working age social security payments in Australia – at least temporarily.</p> <p>This chart shows where Australia sat in 2019 compared to other members of the Organisation for Economic Co-operation and Development on replacement rates – the percentage of previous after-tax earnings that an unemployment payment provided to a single unemployed worker who had previously been on two-thirds of the average wage.</p> <p>Australia is coloured red, and is at the bottom of the pack.</p> <p>A <a href="https://insidestory.org.au/social-protection-and-the-viral-recession/">number of countries</a> have boosted their payments, at least temporarily, in response to the coronavirus.</p> <p>The chart below shows where Australia and New Zealand and France sit now, compared to the 2019 replacement rates of other countries.</p> <p>Australia is again coloured red, but has climbed toward the middle of the pack.</p> <p>The charts show that Australia’ short-term earnings replacement rate climbs from 38% to 68%, because the base rate nearly doubles while rent assistance stays the same.</p> <p>Replacement rates will be lower for higher income workers who lose their jobs and higher for part-time workers and casuals.</p> <p>It is worth noting that other countries are adopting approaches that differ in where support is being targeted. Denmark, for example, is providing a direct wage supplement to employers of 75% of wages up to a ceiling, on the condition that they do not lay off workers.</p> <p>This is actually less than the current replacement rate of 84% in Denmark, but if it is successful it would effectively mean that Danish workers would continue to receive their normal salary (a 100% “replacement rate”).</p> <p>It remains to be seen whether that strategy works.</p> <p><strong>Improvements on delivery</strong></p> <p>The government has indicated that the stimulus package is “scalable”, meaning that it is possible to increase the amounts even further and to extend their duration.</p> <p>And the government has already fixed some gaps in its initial plan relating to students and newly arrived residents and temporary visa holders. Permanent residents will be eligible for assistance immediately and not subject to current waiting periods - which can be up to four years.</p> <p>Without extending benefits to temporary visa holders we would have had what academics <a href="https://insidestory.org.au/of-visas-and-viruses/">Henry Sherrell and Peter Mares</a> warned would be</p> <p><em>hundreds of thousands of people who are suddenly unemployed, without access to welfare, and without a method to return to their country of citizenship.</em></p> <p>The provisions of the special benefit that will be available to temporary visa holders <a href="https://www.servicesaustralia.gov.au/individuals/services/centrelink/special-benefit/who-can-get-it#a1">define</a> severe financial hardship as earning less than the highest special benefit fortnightly payment, being unable to improve that financial position and having limited savings.</p> <p>There is another group whose status should be clarified urgently - that is people who have applied for permanent residence and are still in that application process. There is a case for treating them as if they had already become permanent residents rather than temporary workers.</p> <p><strong>The ‘benefit cliff’ remains</strong></p> <p>A remaining downside with potentially big unintended consequences is the legislated proposal doesn’t yet adjust the spouse income test, excluding many couples where one earner loses their job and leading to a perverse and undesirable “benefit cliff”.</p> <p>If the recipient’s spouse is working and not receiving a Jobseeker or equivalent payment, then the JobSeeker payment will be reduced by <a href="https://www.servicesaustralia.gov.au/individuals/topics/income-test-jobseeker-payment-partner-allowance-and-widow-allowance/29411">60 cents for every dollar the partner earns over $994 per fortnight</a>.</p> <p>This means that the recipient can receive some JobSeekers Payment – and hence the full $550 per fortnight Coronavirus supplement - until the working partner’s income reaches $1,844 per fortnight. At that point they face the <a href="https://theconversation.com/getting-poorer-while-working-harder-the-cliff-effect-113422">“benefit cliff”</a>.</p> <p>If the working partner has an income of $1840 per fortnight, the recipient gets the full supplement of $550 per fortnight, but if the worker has an income of $1850 a fortnight, the recipient gets nothing. The same cliff faces single people, as well.</p> <p>But this partner income threshold of $1850 per fortnight ($925/week) is right in the middle of the Australian income distribution.</p> <p>We calculate that, among two-earner couples aged 25-54, of the primary earners who lose their job, about half will get the Coronavirus Supplement, while of the secondary earners, only somewhere between a quarter and a third will get it.</p> <p>(These are rough estimates based on Bureau of Statistics income survey estimates of the personal income distributions).</p> <p>Given that in most couples the secondary earner is female, the different treatment has the potential to discriminate against women.</p> <p>One way to eliminate the cliff would be to integrate the Coronavirus Supplement more properly into the income support system, so that people with spouse income above these cutoffs would continue to receive a reduced payment.</p> <p>The government has asked for power to fix this issue via regulation, but has not yet announced how it will address it.</p> <p><strong>The scale of the challenge</strong></p> <p>An extra <a href="https://www.aph.gov.au/Parliamentary_Business/Hansard/Hansard_Display?bid=chamber/hansardr/bead2837-76c9-4ce9-952b-eafe8e2d614f/&amp;sid=0045">one million</a> recipients (the treasurer’s estimate) would mean that the share of the working age population receiving income support climbed from 14.2% to 18.7%, an increase of 4.5 percentage points, which is bigger than the 3.5 and 3.8 percentage point increases during Australia’s two previous post-war recessions in the early 1980s and early 1990s.</p> <p>In both of these earlier recessions, the unemployment rate shot up from under 7% to near 10% or higher within a year. The current increase will take place in the next six months, rather than over a full year.</p> <p>Not all the effect will directly be in the unemployment rate. Some will be in the non-participation rate as people decide to neither work nor look for work.</p> <p>The best measure to watch to track the labour market will be the reduction in hours worked.</p> <p>International experience also suggests that it will be substantial. <a href="https://www.bloomberg.com/news/articles/2020-03-20/canada-sees-500-000-employment-insurance-applications-this-week">Service Canada</a> is reported to have received more than 500,000 applications for Employment Insurance in the past week, 20 times the number recorded in the same week a year ago and equivalent to about 2.5% of the labour force. Similar trends have appeared in the <a href="https://www.theguardian.com/business/grogonomics/2020/mar/24/when-it-comes-to-unemployment-in-australia-definitions-have-been-broken">United States</a>.</p> <p>In Australia, we are already seeing the payment system struggling under <a href="https://twitter.com/ServicesGovAU/status/1242225599835516929?s=20">the load of new applications</a>.</p> <p>Ultimately, the key goal of our economic response to the coronavirus must be to share the economic costs.</p> <p>The government has made an excellent start in the package announced on Sunday and extended on Monday.</p> <p>But we have to be prepared to ramp it up and expand support so that everyone living in Australia is adequately supported and the burden of the crisis is shared fairly.</p> <p><em>Written by Peter Whiteford and Bruce Bradbury.

Coronavirus Supplement: What is it and are you eligible?

<p>COVID-19 is impacting the economy and its people significantly. But the Australian government has announced they will be giving more money to welfare recipients in an effort to soften the disastrous blow.</p> <p>Australian Prime Minister Scott Morrison also said he is also helping more people access welfare payments by waiving some asset tests and waiting periods.</p> <p>"We will be supercharging our safety net," Mr Morrison said on Sunday.</p> <p>"This is focusing on those who are going to feel the first blows."</p> <p>The Coronavirus Supplement has caused great interest since it was first revealed to the public in Sunday’s press conference.</p> <p>In short, it is an additional payment that is added on top of the income people on welfare already receive.</p> <p>The supplement is $40 a fornight ($275 a week), meaning the JobSeeker Payment will almost double.</p> <p>Those that are eligible for the Supplement include:</p> <ul> <li>JobSeeker Payment (formerly known as the Newstart Allowance)</li> <li>Sickness Allowance</li> <li>Youth Allowance for jobseekers</li> <li>Parenting Payment Partnered</li> <li>Parenting Payment Single</li> <li>Partner Allowance</li> <li>Farm Household Allowance</li> </ul> <p>Those already receiving one of the welfare payments listed above don't actually have to do anything.</p> <p>Services Australia will automatically pay the Coronavirus Supplement to eligible recipients each fortnight.</p> <p>Those who are not currently receiving welfare will need to apply.</p> <p>Payments for the Coronavirus supplement will begin on April 27 and will be available for at least six months.</p> <p>It has been announced small business owners and casual workers will also be eligible for the payment if they find themselves earning less than $1,075 a fortnight.</p> <p>Are small business owners and casual workers eligible?</p> <p>Treasurer Josh Frydenberg said the Government will go to lengths to ensure the Australian people who have found their business is closed, or that their customers have disappeared, or who have had causal shifts cut may be able to have access to the Coronavirus Supplement.  </p> <p>“We have waived the assets tests and waived the waiting period but there is still the income test so if you earn $1,075 a fortnight you will get that full $550 Coronavirus Supplement,” Mr Frydenberg said.</p> <p>“This is good news for a sole trader who is still in work but has seen the income reduce.</p> <p>“If you are a casual and you still have some hours but your income has fallen below that $1,075 a fortnight you will get the supplement.”</p> <p>It is important to remember the Australian Government has temporarily expanded eligibility for the JobSeeker and Youth Allowance payments, meaning you may be eligible if you're:</p> <ul> <li>A permanent employee who has been stood down or lost your job</li> <li>A sole trader, self-employed, a casual or contract worker whose income has reduced</li> <li>Caring for someone who's affected by coronavirus</li> </ul> <p>Income testing will still apply but if you're earning less than $1,075 a fortnight, Centrelink should approve your claim, meaning you would get the supplement.</p> <p>How do I apply for JobSeeker or Youth Allowance?</p> <p>Those wanting to apply for a Jobseeker or Youth Allowance must do so<span> </span><a rel="noopener noreferrer" href="https://my.gov.au/LoginServices/main/login?execution=e2s1" target="_blank">online through myGov using a Centrelink account</a>, or <a rel="noopener noreferrer" href="https://www.servicesaustralia.gov.au/individuals/contact-us/phone-us" target="_blank">contact Services Australia by phone for more details</a>.</p> <p>But the <a rel="noopener noreferrer" href="https://www.abc.net.au/news/2020-03-23/mygov-website-down-centrelink-massive-queues-coronavirus/12080558" target="_blank">myGov system is experiencing overwhelming demand, causing the website to crash</a> and creating long queues on both the phone hotline and in-person at service centres.</p> <p>Centrelink issued a statement warning people “it will take a little longer than usual” to get help due to the MyGov website currently crashing as it is experiencing overwhelming demand.</p> <p>“Please consider the health and safety of our customers and staff and do not visit our service centres unless there's a critical need for you to be there,” the statement read.</p> <p>The Government plans to hire an additional 5,000 staff for Services Australia — the agency responsible for Centrelink payments — to help deliver the new measures</p> <p>Centrelink and the Government has also announced the ordinary waiting period has been waived.</p> <p>They also said they will are waiving the liquid asset test waiting period, newly arrived residents waiting period, and seasonal work preclusion period if you are eligible for the Coronavirus Supplement.</p> <p>Income maintenance and compensation preclusion periods will continue to apply.</p> <p>Worth noting for those wanting to know if they can access employer entitlements including annual leave or sick leave - the answer is no. The government is not currently allowing people to receive these entitlements while on Job Seeker or Youth Allowances.</p> <p>You also can't receive the payments if you're accessing income protection insurance.</p> <p>The Prime Minister said in his Sunday press conference that the economic stimulus measures implemented so far were “unprecedented”.</p> <p>They are worth $189 billion and account for around 9.7 per cent of the nation’s GDP in total.</p> <p>However, he went on to say: “This will not be the Treasurer and my last visit to these podiums to make announcements on these measures,” Mr Morrison said.</p> <p>“This is focusing on those who are going to feel the first blows. There will be more packages and more support.”</p>

How to get the most out of food supplements

<p><em><strong>Dr Libby is a nutritional biochemist, best-selling author and speaker.</strong></em></p> <p>Nutritional supplements are very common these days.</p> <p>For some people, supplements are necessary to cover nutritional gaps that can arise from excluding certain foods from their diet, regardless of whether this is by choice or necessity. For others, supplementation is something they view as an insurance policy, to ensure their nutrient intake is adequate if they don't always eat as well as they know they should.</p> <p>Perhaps you choose to take a multivitamin to top up your intake of a range of nutrients, or maybe you take a specific vitamin or mineral that is lacking in your diet. Or you might take an omega-3 fatty acid supplement, or use a greens powder as a convenient way to increase your vegetable intake.</p> <p>Good quality nutritional supplements are a financial investment, so you definitely want to be sure you are getting the maximum benefit from what you are taking.</p> <p>If you're not effectively absorbing the nutrients from your supplements, you're not going to be getting all of the potential benefits from these. The old adage that you are what you eat isn't quite correct. You are what you eat, absorb and assimilate, and this is something to consider when it comes to supplementation, too.</p> <p>Let's consider some common nutritional supplements and how you can get the most out of these.</p> <p><strong>1. Iron</strong></p> <p>Iron deficiency is the most common nutritional deficiency in the world, and it can be difficult to restore depleted iron levels without a supplement. Many iron supplements lead to constipation, but most people find this does not happen with liquid iron supplements.</p> <p>If you take an iron supplement, avoiding tea, coffee or red wine within at least an hour of taking your supplement is essential, as the tannins inhibit iron absorption. Consuming calcium-rich foods away from iron-rich foods and iron supplements can also make a difference to iron absorption, as iron and calcium compete for absorption in the gut.</p> <p>If you take a calcium supplement, it's important that this is taken at a different time to your iron supplement. The same goes for zinc supplements – to maximise absorption, they should be taken at a different time to iron supplements.</p> <p>Vitamin C, however, significantly enhances the absorption of iron. So if you take an iron supplement, you might like to check the label to ensure it also contains vitamin C.</p> <p><strong>2. Zinc</strong></p> <p>To maximize absorption, zinc supplements are best taken away from food (before bed is a good time) and away from any iron, calcium and folic acid supplements. Tannins in tea, coffee and red wine can also inhibit zinc absorption, as can fibre, so these are best avoided for at least an hour either side of taking zinc.</p> <p><strong>3. Vitamin D</strong></p> <p>Vitamin D is a fat-soluble vitamin, so absorption of vitamin D supplements will be enhanced when taken with a source of dietary fat. This means it's best to take your vitamin D supplement with a meal that includes nourishing fats from foods like avocado, nuts, seeds, extra virgin olive oil or oily fish such as salmon. There are two different forms of vitamin D – they are vitamin D2 and vitamin D3. Vitamin D3 is the more bioavailable form.</p> <p><strong>4. Multivitamin</strong></p> <p>Multivitamin supplements are best taken with a meal. When you eat, stomach acid is produced to help digest your food properly, and this will also enhance absorption of some of the nutrients in your multivitamin. The fats that are present in the meal will also help your body to absorb the fat-soluble vitamins (vitamins A, D, E and K). It's also best to avoid drinking coffee, tea and red wine within an hour of taking your multivitamin to get the most out of it.</p> <p>While nutritional supplements can help to bridge any nutritional gaps or to address nutrient deficiencies, please be aware that they cannot replace a highly nutritious way of eating. Nothing in this world can.</p> <p><em>Written by Dr Libby Weaver.

What supplements really matter over 60

<p><em><strong><img width="186" height="184" src="https://oversixtydev.blob.core.windows.net/media/44990/image__186x184.jpg" alt="Image_ (36)" style="float: left;"/>Dr Vincent is a world-renowned clinical nutritionist, food scientist and expert on antioxidants.</strong></em></p> <p>With proper care for your physical and mental health, people over 60 can be as active as they want – and importantly, now have the time available to participate in all of the activities they want.</p> <p>While each of us ages differently, what we all have in common is that what we did during our younger years plays a major role in our life as we get older. So while we all need to take extra care of our health and wellbeing while we get older, some of us are going to have to deal with some extra challenges as a result of some not-so-good decisions earlier in life.</p> <p><strong>What type of changes can you expect to happen to the body after 60</strong></p> <p>Both males and females will experience impossible-to-miss changes in their health, both physically and mentally.</p> <p>One of the very first things that people start to notice is the slowing down of the body’s metabolism. This, combined with less physical activity, means it’s much easier to put on weight.</p> <p>It is important to carefully select the types of food you eat to make sure that the nutrient intake is sufficient, without consuming excessive calories. This is especially important for people with conditions such as diabetes, high cholesterol or high blood pressure.</p> <p>At the cellular level, as we age, our cells are more prone towards becoming inflamed. Cellular inflammations may manifest in conditions like osteoarthritis, IBS, dermatitis and other skin issues. </p> <p>Maintaining a good circulatory system is also paramount, not for your physical health, but also for the mind. Making sure that our brain receives enough blood flow and oxygen helps with maintaining alertness, memory and concentration.</p> <p>I always believe that the best way to get our nutrients is from wide range of fresh foods, however it is almost impossible to have the perfect diet every day. With advancements in science and technology, many of these nutritional needs that are not fulfilled from our daily diet can be supplemented.</p> <p>The most important thing in selecting health supplements is that we only take what our body needs.  More doesn’t always mean better, as a matter of fact, in this case, more can potentially be harmful.</p> <p>As we age, our digestive system and our body’s ability to metabolise nutrients is no longer its peak, therefore taking unnecessary or non-absorbable supplements will over load the work and functions of our organs such as kidney and liver.</p> <p>Omega 3 fish oil is a very basic but important supplement as it helps with circulation as well as reducing inflammation. Most people do not eat fish often, and even when they do, the risk of heavy metal contaminations from seafood is quite frightening. Fish oil is derived from the tissues of oily fish and unfortunately fish absorb lots of bad things, including chemicals. This is why many people opt to consume omega 3 fish oil in tablet form instead of eating a lot of fish.</p> <p>A good, potent antioxidant – which is 100 per cent natural – is activated phenolics, which is derived from Australian apples. This supplement keeps the body healthy at the cellular level, which is essential because healthy cells means a healthy body. Activated phenolics has a high absorption rate, because what counts is not what is measured and stated on the label, but what our body can actually absorb and utilise. As an expert in antioxidants, I strongly believe everyone should take antioxidants every day because they help to mop up free radicals around the body. Free radicals cause cell damage which causes cancer, inflammation and other chronic diseases. Anything we can take that keeps our cells healthy is an important part of our diet and helps to keep healthy.</p> <p>Fibre supplements such as oligospectine are also very useful to maintain a healthy digestive system. Not only does it help to optimise nutrient absorption, but it helps with regularity as well as overall health – after all, around 70 per cent of your body’s immune system is from the digestive system.</p> <p>Those who have specific diets such as vegetarianism or veganism may need supplements such as B12 or an amino acid complex. Similarly, people with health conditions or who are on certain medications may need more specialised supplements, so it’s best for you to discuss this with your health professionals.</p> <p>Health may not be the MOST important thing in life, but being healthy enables us to attend to all the important things in life, such as our family, our loved ones and living life.</p>

Can herbal supplements treat mental health issues?

<p>Stress, anxiety, and depression. Three mental health issues that are widely felt amongst amongst New Zealanders, yet often go unchecked.</p> <p>For anybody who suffers with their mental health, herbal and off-the-shelf remedies and supplements are often the first thing they seek out before discussing their needs with a professional healthcare provider.</p> <p>But is there any science proving that any of these herbal treatments actually work?</p> <p>It's essential to know that just because a product is natural, herbal, or available without a prescription, doesn't mean it's safe. Some products can also cause negative interactions when used with other drugs.</p> <p>You must also be aware that no herbal or natural supplement will address the underlying cause of any kind of mental illness. You may be provided with a temporary solution, but it's value will likely be short-term.</p> <p><strong>Lemon balm</strong></p> <p>Use of Melissa officinalis, or lemon balm, dates back to the Middle Ages for stress and anxiety relief.</p> <p>This herb is part of the mint family and <strong><span style="text-decoration: underline;"><a href="http://umm.edu/health/medical/altmed/herb/lemon-balm" target="_blank">some small scientific studies</a></span></strong> have shown consumption of it can produce slight feelings of calmness for several hours.</p> <p>Positive effects are only felt when consuming a lot of this herb (1600mg has been linked to six hours of calmness), but luckily, no scientific studies have shown adverse effects of lemon balm even in high doses.</p> <p><strong>St. John's wort</strong></p> <p>Commonly found as a tea or in pill supplement form, St. John's wort has been proven in some clinical trials to help with some types of depression because it can raise serotonin levels. However, <span style="text-decoration: underline;"><strong><a href="https://nccih.nih.gov/health/stjohnswort/sjw-and-depression.htm" target="_blank">it's potentially very dangerous</a></strong></span>, too.</p> <p>St. John's wort interacts with many prescription medications, and should never be taken without your doctor's consent if you're being prescribed anything.</p> <p>Particularly, if combined with selective serotonin reuptake inhibitor (SSRI) drugs such as fluoxetine (Prozac), paroxetine, and other antidepressants, St. John's wort can trigger psychotic events, autonomic dysfunction (sweating, increased blood pressure), and motor effects, because your body struggles with such an increased level of serotonin.</p> <p><strong>Vitamin B</strong></p> <p>Many vitamin B supplements are marketed for stress relief in New Zealand. Fatigue and low energy are scientifically linked with a vitamin B deficiency, but it is plentiful in the average diet and only usually recommended for vegetarians, vegans, and other vulnerable groups.</p> <p>There's very little scientific evidence that stress increases a person's need for vitamin B, or that a big dose of it is required to "get through" times of stress.</p> <p>However, <span style="text-decoration: underline;"><strong><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4290459/" target="_blank">one promising Australian study</a></strong></span> from 2014, which looked specifically at work-related stress, saw reductions in it between weeks four and 12 when taking a regular vitamin B supplement.</p> <p><strong>Probiotics</strong></p> <p>Though the link between the gut and mental health is an emerging issue in the health industry, there's no clear evidence that probiotics (e.g. as a pill supplement form) reduce symptoms of stress or anxiety.</p> <p>However, <strong><span style="text-decoration: underline;"><a href="http://newsroom.ucla.edu/releases/changing-gut-bacteria-through-245617" target="_blank">one University of California Los Angeles study has found</a></span></strong> that it found people that consumed two cups of probiotic yoghurt per day (which contained four types of live bacteria: Bifidobacterium, Streptococcus, Lactococcus, and Lactobacillus) had calmer reactions to stressful situations than those who didn't eat the yoghurt. What constitutes a "calmer reaction", however, is subjective so we can't take this as conclusive evidence.</p> <p>The only known side effects of probiotics are bloating and digestive gas.</p> <p><strong>Valerian root</strong></p> <p><span style="text-decoration: underline;"><strong><a href="http://umm.edu/health/medical/altmed/herb/valerian" target="_blank">There's not enough evidence to show that valerian root</a></strong></span> – a common ingredient in natural sleeping medications – actually works.</p> <p>Limited research shows it can reduce heart rate and feelings of stress when put under pressure, and there's even one study that showed it was more effective that diazepam for anxiety during a two-week period, when used alongside St. John's wort.</p> <p>Low doses are considered to be safe, but high doses can result in blurred vision, headaches, and lethargy.</p> <p><strong>Kava</strong></p> <p>Kava, a plant (and mild intoxicant) that grows in some Pacific nations, is supposedly useful in treating anxiety.</p> <p>It can bring about feeling of relaxation, and sometimes even euphoria, as it causes the body's dopamine levels to rise. There is also <span style="text-decoration: underline;"><strong><a href="https://trialsjournal.biomedcentral.com/articles/10.1186/s13063-015-0986-5" target="_blank">some clinical evidence</a></strong></span> that it helps with stress, insomnia, and depression and is generally considered safe in when consumed occasionally.</p> <p>However, it's potential to interact with other drugs is high. It can be addictive, and can't be combined with alcohol, dopamine, haloperidol, acetaminophen, and benzodiazepines. It can cause excessive drowsiness when used alongside SSRIs, and it can injure the liver in healthy people.</p> <p><em>Written by Lee Suckling.
