- and lack of nutrients is an overlooked problem

According to the statistics, far too many patients contract an infection while being hospitalized in a Danish hospital. This has enormous human and economic costs that need to be addressed. Hospital infections are not only a consequence of poor hygiene, it actually turns out that 40 percent of the patients are malnourished to some degree, which impairs their immune system and makes them an easier target for infections. Lack of vitamin C, vitamin D, selenium, zinc, and iron seem to be the big and overlooked problem.

- or are you wasting money on the wrong supplements?

It is only natural to expect a nutritional supplement to be absorbed and deliver an effect. However, for this to happen, you must look for products with documentation. Countless multivitamin products and supplements with Q10, selenium, chromium, magnesium, and iron have very poor quality and are not properly absorbed. Our ageing process alone impairs the uptake of vitamins and minerals, and the same is the case if we lack essential fats, have too high calcium levels, or use antacids and other types of medicine – so this also needs to be taken into account.

- but researchers warn against reduced intake levels

Even if you eat a healthy and balanced diet, it can be difficult to get enough selenium because of climate changes and nutrient depletion of the soil, especially in Europe. This was shown in a study conducted by Swiss scientists. Selenium is very important for the immune system, but how much do we need to be optimally protected against infections? There also appears to be a connection between widespread selenium deficiency and the increased rate of cancer.

- which many people lack

It is not the actual COVID-19 virus that can become lethal. It is the immune system’s overreaction with hyperinflammation and a storm of cytokines that destroys healthy tissue in the lungs, the cardiovascular system, and other places in the body, according to a new article that is published in The Lancet. The capacity of the immune system determines if an infection like COVID-19 is either harmless or life-threatening. For that reason, hygienic measures, masks, isolation, and delayed vaccines are not sufficient. We also need to bolster our immune system against COVID-19 and other pandemics that may occur in the future. Let’s look closer at vitamin C, vitamin D, selenium and zinc, all of which are essential for preventing a well-functioning immune system from going off its rails. What is also worth mentioning is that many people lack these nutrients, especially older people and other exposed groups.

The number of older people is constantly increasing, and more and more people suffer from Alzheimer’s disease and other types of dementia. Apparently, seniors who take a daily multivitamin can improve their memory and slow down their cognitive decline, according to a meta-analysis that is published in Journal of Clinical Nutrition. Older people generally have increased need for certain vitamins and minerals because of poor nutrient absorption in the digestive system, impaired enzyme functions, oxidative stress, and regular use of medical drugs that can interact with the nutrients. But how do different vitamins and minerals affect brain health?

Around one in six pregnancies results in spontaneous abortion. Although there can be different reasons for this, scientists have found that eating a healthy diet with lots of vegetables, fruit, fish, shellfish, eggs, and grains can lower the risk by over 50 percent. This was shown in a meta-analysis from the University of Birmingham in England. Earlier research shows that selenium, a trace element that many people are deficient in, plays a particularly important role.

According to Bruce Ames, an American biochemist, ageing processes are largely due to lack of nutrients. One important contributing factor is the fact that our uptake and utilization of vitamins and minerals decrease with age. In addition, a lot of different types of medicine block our ability to utilize different nutrients. As a result of this, many of our enzyme processes slow down, making our cells increasingly vulnerable and that increases our risk of disease. Nonetheless, there is a lot we can do to optimize our intake and utilization of nutrients, particularly with respect to vitamin B12, vitamin D, calcium, iron, selenium, and zinc. It is also worth taking a look at Q10 for energy turnover and melatonin for healthy sleep. Our endogenous synthesis of both compounds decreases with age.

Supplementing with strong antioxidants such as beta-carotene, vitamin E, selenium, and coenzyme Q10 may help patients with cystic fibrosis by reducing a number of the respiratory infections that come with the disease. This was seen in a study by researchers at the Children’s Hospital Colorado and the University of Colorado, United States.

Impaired sperm quality if one of the major reasons for involuntary infertility. Studies show that oxidative stress, an imbalance between harmful free radicals and protective antioxidants, causes damage to sperm cells. In a review article that is published in Reproductive Sciences, a group of researchers look closer at different molecular mechanisms and how vitamins C, E, selenium, zinc, and coenzyme Q10 plus other antioxidants protect the vulnerable sperm cells.

Veganism is on the rise, and experts have different views on whether or not plant-diets are suited for children. A team of Polish scientists has now discovered that children on vegan diets have low stature and lower bone density than children who eat meat and dairy products. Children on vegan diets also are also more likely to lack amino acids, vitamin B12, vitamin D, vitamin A, iron, selenium, iodine, and the omega-3 fattyacid DHA (docosahexaenoic acid). It is particularly important for growing children to get enough nutrients to support their muscles, bones, brain, and a variety of enzyme processes. Also, children on vegan diets should be given relevant supplements to compensate for their shortcomings.

It is estimated that one billion people worldwide lack selenium. This has fatal consequences for public health because it increases the risk of virus infections, thyroid disorders, cardiovascular diseases, cancer, neurological disorders, and involuntary infertility. Adding to that problem is the fact that mercury, a known environmental toxin, throws a wrench into selenium’s different functions. In the following, we have compiled a long list of studies that look closer at the consequences of selenium deficiency and the advantage of optimizing the body’s selenium status with help from supplements.

The widespread selenium deficiency in Europe increases the risk of infections, inflammatory bowel disorders, and abnormal cell development. In a new review article published in Nutrients, the authors look at selenium’s role in the highly developed immune defense. This includes the immune defense’s communication, which is vital for our ability to fight off viruses and germs swiftly and directly, and for avoiding unwanted inflammation that can become potentially life-threatening. Seleniumalso serves as a very effective antioxidant that protects cells and their DNA against oxidative damage. In addition, selenium has a number of anti-cancer mechanisms.

We all need loads of energy to help us through the day feeling on top of the world. Needless to say, this requires stable blood sugar levels, daylight, exercise, and a good night’s sleep. But what are the energy-providing substances in our food? And why are Q10 and particular vitamins and minerals so essential for our energy metabolism and our physical and mental well-being? An article recently published in Medical News Today looks at this and explains that being deficient of a single nutrient can affect our metabolism, energy levels, and weight regulation. Luckily, this can be compensated for so we get the necessary energy boost.

Birth control pills are commonly used as a source of prevention. Most women seem to tolerate the pills rather well, but there are known side effects such as headaches, mood swings, and a slightly increased risk of blood clots and breast cancer. The different side effects are a result of the birth control pills and their disturbing impact on various enzyme processes, which depend on most B vitamins, vitamin C, magnesium, selenium, and zinc. Vitamin C, zinc, and selenium also serve as effective antioxidants that protect our cells and cardiovascular system against oxidative stress. It is therefore essential to get plenty of these nutrients in order to lower the risk of side effects.

According to Danish research, more than one in three women suspect that their birth control pills cause side effects. Other studies show that birth control pills affect the body’s ability to utilize several different B vitamins, vitamin C, vitamin E, magnesium, selenium, and zinc. The lack of these essential nutrients contributes to a number of common side effects such as fluid retention, blood clots, cancer, and depression.

Breast cancer is very common in the Western world and modern society. The disease is thought to be associated with lifestyle factors and lack of essential nutrients. For instance, it has been known for a long time that lack of vitamin D increases the risk of breast cancer. According to a new study that is published in the science journal Endocrinology, there is also a link between lack of vitamin D and the development of metastases in the lungs. Previous research also shows that the widespread deficiency of selenium, iodine, omega-3 fatty acids, and melatonin can increase the risk of breast cancer but supplements can help prevent the disease and possibly be used as add-on therapy.

Breast cancer is the leading cancer form among women. Even though treatments have gotten a lot better the disease still has a high death toll. A Swedish-German study shows that having low levels of seleniumin the blood worsens the prognosis, whereas having a higher selenium content in the blood can increase the odds of surviving breast cancer. Unfortunately, selenium deficiency is rather common in Europe. According to the scientists behind the new study, measurements of selenium status can be used to optimize blood levels of the nutrient, thereby improving treatment correspondingly.

Having higher blood levels of selenium, an essential trace element, increases a breast cancer patient’s chances of 10-year survival, according to a Polish population study that is published in the science journal Nutrients. Also, earlier research has shown that supplementation with selenium yeast can lower the risk of contracting a variety of different cancer forms. The agricultural soil in Europe is very low in selenium and that is one of the reasons why selenium deficiencies are so common. The question is how much selenium we need to optimize levels in the blood.

Yes, according to a new study published in Free Radical Biology & Medicine, lack of seleniumlowers the kidneys’ sodium excretion via different mechanisms, and that leads to elevated blood pressure. The study results are highly relevant because hypertension and subsequent premature death is a growing global problem. Selenium deficiency is also a widespread problem. One billion people worldwide are believed to be lack this essential nutrient, primarily because of the selenium-depleted agricultural soil in large parts of China, Europe, and other places.

COVID-19 represents a serious global threat against public health and the economy because we still lack a vaccine and effective therapies. When COVID-19 becomes life-threatening it is primarily because the immune defense overreacts with a cytokine storm and hyperinflammation that destroys healthy tissue in the lungs, the circulatory system, and other places. Older people and heart failure patients already suffer from chronic low-grade, uncontrolled inflammation, to which nutrient deficiencies contribute and make the patients increasingly vulnerable. This also applies to people with metabolic syndrome and diabetes, many of which are overweight. For that reason, scientists affiliated with universities and research centers in Norway, Sweden, and Russia have searched the scientific literature to find studies that focus on whether supplementation with vitamin D, selenium, and zinc can help prevent a COVID-19 infection from escalating and becoming life-threatening.

Everyone is affected by electromagnetic radiation from cell phones, device screens, the electricity supply and other electric systems. The brain’s neurons are particularly vulnerable, especially because electromagnetic radiation can increase the neuronal uptake of calcium ions, which makes the neurons overactive and may even cause them to perish. A study published in News Medical Life Sciences shows that too much calcium in the brain increases the risk of Alzheimer’s disease and digital dementia in young individuals. The increased electromagnetic radiation also generates loads of free radicals in the body that can cause oxidative stress and cellular damage because it outperforms the body’s different antioxidants. This was described in an article published in The Journal of Microscopy & Ultrastructure that also mentions how electromagnetic radiation can cause stress, headaches, fatigue, anxiety, and other symptoms.

- and a common trait in most chronic diseases

Although chronic inflammation is not something that you feel as such, it sets the stage for a number of symptoms and a host of different diseases including fatigue, overweight, diabetes, cardiovascular disease, rheumatism, metabolic disorders, asthma, periodontal disease, bowel infections, depression, Alzheimer’s disease, sclerosis, and cancer. Not surprisingly, people are more and more hooked on the anti-inflammatory lifestyle, and we will take a closer look at studies showing how fish oil, vitamin D, selenium, magnesium, and zinc contribute to preventing and fighting inflammation, related diseases and premature death. Any nutritional supplements must be of a proper quality that the body can absorb, and they should contain therapeutic dosages.

- that are a threat to public health

Climate changes and soil depletion increase the risk of selenium deficiency, especially in Europe as shown by Swiss scientists. Selenium is an essential nutrient, and existing studies clearly show that low selenium intake increases the risk of cancer, metabolic disorders, impaired immunity, poor sperm quality, and atherosclerosis. Selenium deficiencies are therefore to be taken seriously and should be prevented one way or another. A good way to get enough of the nutrient is by taking a high-quality selenium supplement.

The coronavirus has spread from Wuhan in China to a number of continents, where it has caused massive fear and affected daily life and the global economy. Although most people that get the infection experience a mild course of events, the greatest fear is the potentially life-threatening complications in the respiratory system caused by oxidative stress, which have already taken thousands of human lives. Chinese scientists now call for early intravenous therapy with large doses of vitamin C to prevent oxidative stress and the life-threatening complications that follow in the wake of a derailed immune system. Many researchers also claim that higher intake of vitamin C from dietary sources or supplements help prevent by boosting and regulating the immune system in the upper respiratory tract. The same goes for vitamin D and selenium.

A new study links thyroid disorders to female infertility. At the same time, it is known that selenium, an essential micronutrient, is required for normal functioning of the thyroid gland. Modern diets are depleted of selenium and the question is: Could selenium supplements be a good place to begin for infertile couples before embarking on expensive IVF therapy?

- and antioxidants like selenium, Q10, and melatonin play a role in prevention and treatment

There is a link between depression, dementia and Alzheimer’s disease. Also, it appears that chronic stress contributes to oxidative stress and brain cell damage. In a review article that is published in the science journal Antioxidants, researchers look closer at how oxidative stress affects the brain. They also study how antioxidants can be included in the prevention and treatment of Alzheimer’s disease, and why the most promising results are seen with selenium, Q10, melatonin, vitamin E, turmeric, and polyphenols. With regard to depression, selenium, zinc, vitamin E, turmeric, and saffron have demonstrated the greatest potential.

A panel of physicians and professors collaborating with the Swiss Society for Nutrition (SSN) recently reviewed the scientific evidence on the role of micronutrients in supporting a well-functioning immune defense for optimal health with particular focus on viral infections related to COVID-19. They conclude that there is widespread lack of vitamin C, vitamin D, selenium, zinc, and omega-3 fatty acids, all of which are crucial nutrients for the immune system. These deficiencies contribute to new waves of COVID-19 and can cause the infections to become life-threatening. The panel calls for immediate action with relevant focus on diet and supplements.

Infertility affects around one in seven couples. WHO considers it a global health problem. One of the leading causes is impaired semen quality, and Danish, Norwegian, and German men have lower sperm quality than any other male populations. Impaired sperm quality may be a result of an unhealthy lifestyle with stress, tobacco, stimulants, and hormone-disrupting compounds. On the other hand, scientists from Mexico have found that supplements of zinc, selenium, Q10, and omega-3 have an effect on the number of sperm cells and their quality. Other studies show that zinc and selenium protect sperm cells and are important for testosterone levels.

It appears so. Iodine is an essential trace element that is vital for metabolism and estrogen balance. Iodine also helps the body get rid of environmental toxins. In fact, exposure to these toxins increases our need for iodine, and many experts believe that the official recommendations for iodine are too low.

- and what else does it do?

The Russian invasion of Ukraine has increased the fear of nuclear warfare or radioactive leaks from local nuclear power plants. For that reason, many people have purchased iodine tablets to protect themselves from radioactive contamination. Being relatively close to a radioactive leak creates a sudden need for very large intake of iodine. It is important to realize, however, that the thyroid gland can only store iodine for a limited period of time and it can be dangerous to take extreme doses of iodine. Therefore, it makes no sense to take mega-doses as a preventive measure. On the other hand, it looks as if iodine deficiencies are rather common. Furthermore, we do need a certain amount of iodine to support the thyroid function, estrogen balance, and a number of other things. The question is how much iodine do we need on a day-to-day basis and how much do we need in the case of being exposed to radioactive radiation?

Extreme fatigue, unsuccessful attempts to lose weight, mood swings, dry skin, constipation, swollen throat, and many other symptoms may be a sign of Hashimoto’s disease that slows down the metabolic rate. This thyroid disorder that develops slowly is increasing at a rapid rate. Other thyroid disorders like Graves’ disease that cause hyperthyroidism are also a problem. In a review article published in Nutrients, researchers have looked at how nutrients such as iodine, selenium, iron, zinc, and vitamin D support the thyroid gland, the body’s production of thyroid hormones, and the regulation of chronic inflammation of the thyroid gland. Millions of people around the world lack one or several nutrients that are needed to prevent and treat these common thyroid disorders. Lack of nutrients can also explain why many people receiving medical therapy for their condition aren’t helped. The digestive system and food intolerance may also play a role.

The need for the trace element selenium is increased in pregnant and breastfeeding women because it supports a host of different proteins that are particularly important for tissue growth. Also, selenium supports different antioxidants that protect the unborn baby’s organs and tissues. A new review article published in Nutrients shows that lack of selenium during pregnancy may result in oxidative stress, stunted growth, and low birth weight. This may eventually have consequences for the baby’s development, cognitive skills, and health in general. The authors also mention that an expecting mother’s alcohol abuse may have a more negative health impact if she is selenium-deficient. It is a problem that selenium deficiency is such a widespread problem in Europe and other parts of the world.

In ancient times when our ancestors hunted, they consumed every inch of the animal – from one end to another. Organ meat such as the liver, the heart, and the kidneys were delicacies that contained far more essential nutrients than other parts of the animal. In Western countries, we primarily consume muscle meat. In addition, animals often get unnatural fodder with suboptimal nutrient content. This results in deficiencies and an imbalance between amino acids and fatty acids. In the following article, you can read more about organ meats (also known as offal), bone marrow, and bone broth and their high content of essential amino acids, vitamin B12, iron, selenium, Q10, calcium, magnesium, collagen, glucosamine, CLA, and other vital nutrients. Also, you can read more about why it makes sense to choose meat from free-range livestock.

- which is important for your metabolism and estrogen balance

We humans are exposed to many toxic fluoride compounds from toothpaste, mouth rinses, tap water and mineral water, Teflon pans, cookie sheets, rain clothes, waterproofing agents etc. Fluoride poisoning may increase your risk of thyroid disorders, breast cancer, kidney diseases, ADHD, and birth defects. In addition, the need for iodine is increased, and it is also important to mention that the symptoms of a fluoride poisoning are often similar to the symptoms of an iodine deficiency.

Having healthy-looking hair means a lot to most people. Hair that splits at the ends, hair loss, and other hair problems may be caused by stress, hormone changes, and numerous other factors. In this article, we will take a closer look at the diet and its impact on hair health, and we will look at available studies of protein, iron, zinc, selenium, silica, B vitamins, vitamin D and vitamin A. The fact is, we need plenty of these nutrients in a form that the body can absorb and utilize. On the other hand, getting too much can do more harm than good, according to an article in Dermatology Practical & Conceptual, in which the author has analyzed the available research.

Lack of selenium increases the risk of impaired fertility and complications in connection with pregnancy and birth. Because selenium deficiencies are rather common, both men and women should ideally make sure that they get enough of this essential trace element that is involved in various functions - right from conception to delivery.

-and many chronically ill people do not get the proper diagnosis or treatment

The most harmful heavy metals are mercury, cadmium, lead, nickel, and cobber, but aluminum, fluoride, iron, and calcium can also be toxic. Poisoning with heavy metals and minerals blocks other minerals such as selenium, iodine, magnesium, and zinc, all of which support numerous essential enzyme processes. At the same time, if you lack these important minerals, heavy metals are able to cause unhindered damage and increase your risk of impaired immunity, impaired fertility, autoimmune diseases, thyroid diseases, brain damage, neurological diseases, depression, hypersensitivity, etc. Chronic heavy metal toxicity is an overlooked problem, but in this article, you can read more about the subject and find out how to deal with it.

Selenium deficiency is widespread in Europe and many other parts of the world, negatively impacting public health. On the other hand, adequate selenium intake through diet and supplements can reduce the risk of cardiovascular diseases, diabetes, metabolic disorders, cancer, and early death. A study published in Frontiers in Nutrition suggests that older individuals have an increased need for selenium.

HIV, the virus that causes AIDS, is potentially life-threatening because it attacks central cells in the immune defense. It has also been documented that HIV patients have an increased risk of lacking vitamin D. This can be because of the disease itself, the combination therapy, lack of sun exposure, or other factors. Vitamin D is important for the immune defense, the bones, our mood, and numerous other functions. According to a new article published in MedicalNews Today, it is important to measure HIV patients’ blood levels of vitamin D and possibly give them high-dosed supplements to optimize levels of the nutrient. Earlier studies point to a link between the course of an HIV infections and the body’s selenium status.

Sales of plant-based meat, also known as meat analogue, has increased for environmental reasons and a number of other reasons. However, even if meat analogue does resemble regular animal meat it has an entirely different nutritional value. According to a study from Duke University in the United States, real meat contains 22 different nutrients and metabolites that you do not get from meat analogue. On the other hand, meat based on vegetarian sources contains 31 nutrients and metabolites that are not found in normal meat. The largest difference between the two, according to the scientists, lies in their content of amino acids, peptides, vitamins, phenols, and fatty acids. The researchers also mention that a diet based on vegetable and animal products is complementary because it contains more nutrients.

Hashimoto’s thyroiditis is the most common underlying cause of hypothyroidism. It is characterized by extreme fatigue, weight gain, and a number of other symptoms. Hashimoto’s is an autoimmune condition where antibodies attack the thyroid gland. Many people who get treatment for their disease don’t improve, on the contrary. According to a meta-analysis published in Medicine, however, selenium supplementation appears to be able to reduce the autoimmune reactions and the body’s production of the different antibodies. Selenium helps control the thyroid function but also serves as an antioxidant that protects the thyroid gland against oxidative stress.

- with links to cancer, Parkinson’s disease, and other neurological disorders

The mitochondria are the powerhouses of our cells that churn out energy in a process that involves oxygen, Q10, selenium, and other nutrients. Around 100 years ago, the German Nobel Prize winner, Professor Otto Warburg, demonstrated that even if cancer can be caused by a number of secondary factors, there is only one primary cause: alterations in the mitochondrial oxygen turnover. In his recent book, Tripping over the Truth, molecular biologist Travis Christoffersen describes how contemporary scientists confirm Warburg’s theories and says that we need to look at prevention and cancer treatment from an entirely different angle. Other studies show that Parkinson’s disease, migraine, senility, chronic fatigue, fibromyalgia, epilepsy, and other neurological disorders may be rooted in defects of the mitochondria that have many other functions besides delivering energy. It is therefore vital to take care of the mitochondria throughout life. You can read more about the ketogenic diet that optimizes mitochondrial energy turnover in different mitochondrial diseases.

Ageing is linked to uncontrolled, low-grade inflammation, also known as inflammaging, according to articles published in the journals Nature Medicine and Ageing and Disease. Although chronic inflammation is not felt directly it may set the stage for cardiovascular disease, rheumatism, Alzheimer’s disease, and cancer. Chronic inflammation may also cause virus infections like influenza and COVID-19 to become life-threatening because the immune defense suddenly overreacts and attacks healthy tissue. It is therefore vital for ageing people to protect themselves against chronic inflammation, which means getting plenty of vitamin D, selenium, coenzyme Q10, zinc, omega-3, and melatonin. These are all things that many older people often lack.

- plus thyroid disorders, poisoning, and a lot more

Iodine is the only mineral, which is compulsorily added to foods because it is can prevent goiter. Studies show that iodine also plays a role in the metabolism, the energy levels, estrogen balance and even helps prevent breast cancer. What is more, iodine can help the body get rid of environmental toxins such as fluoride compounds. Many experts believe that the official iodine recommendations are too low, and it is important to make a note of the fact that refined table salt often contains anti-caking agents like aluminum, and that sea salt is not enriched with iodine.

Selenium supports a host of different metabolic processes and serves as an antioxidant that protects our cells. According to recent studies, selenium also has anti-ageing properties that protect us against cardiovascular disease, cancer, dementia, and other age-related diseases. According to a review article published in Medical News Today, selenium also helps against impaired immunity and counteracts chronic inflammation, which is typically seen in connection with ageing processes. A Swedish study of healthy seniors has even showed that supplementation with selenium and Q10 has a positive effect on heart function, quality of life, and life expectancy.

Minerals are involved in countless functions of vital importance to the immune defense. That is why lack of one or several minerals can increase your risk of infections or perhaps trigger unwanted inflammation that can damage healthy tissue. In a new review article that is published in Nutrients, a group of scientists look at magnesium, selenium, zinc, iron, and copper and their role in the immune system. They also look at the fact that vegans, older people, chronically ill, pregnant women, and elite athletes often have nutrient deficiencies that call for supplementation. The agricultural soil in Europe and many other parts of the world is selenium-depleted, which makes it challenging to get enough selenium from our diets. But it is also important not to overdose on minerals. In this article, you can read more about how to optimize your nutrient intake for your immune health.

Kidney stones is a painful and quite common problem. The diet plays a major role and according to a large American population study published in Nutrients, selenium may help prevent the condition. The authors mention that selenium-containing proteins and antioxidants have preventative mechanisms and due to the widespread problems with selenium-depleted farmland, they say that selenium supplementation may be a good way to prevent and manage kidney stones and other pathological changes.

- and increases the risk of degenerative disease and early death

It is commonly known that degenerative diseases such as cardiovascular disease, diabetes, kidney ailments, and liver diseases are often linked to poor quality of life and shorter lifespan. Supplementing with Q10, possibly in combination with selenium yeast, may have a positive influence on the mentioned conditions and lower your risk of premature death by as much as 50 percent or more. In fact, Q10 can help delay the ageing processes by protecting the heart, cardiovascular system, and cells, according to a large review article published online by NCBI (National Center for Biotechnology Information). As mentioned in this article, it is essential to use supplements that are pharmaceutical-grade in order to ensure proper absorption in blood and tissue.

When it comes to COVID-19 and other seasonal virus infections most of the focus is concentrated on vitamin D deficiency. According to a Belgian study, however, lack of selenium and zinc additionally increases the risk of infections, complications, and death, especially among patients who already suffer from chronic diseases. The scientists conclude that supplementation with selenium and zinc may help improve treatments. Selenium and zinc deficiencies are rather common and that is a problem for public health. Even with a healthy diet, it is practically impossible for Europeans to get enough selenium because of the nutrient-depleted farmland. There are also many people with zinc deficiencies due to unhealthy diets, ageing, chronic diseases, and other contributing factors. We must be much more focused on getting enough selenium and zinc, not least for the sake of preventing virus infections and other problems.

- and become increasingly dangerous

Around one billion people worldwide are believed to lack selenium, mainly due to nutrient-depleted farmland. Selenium deficiency makes us more vulnerable to infections and increases the risk of a virus mutating and becoming more dangerous. This was shown in previous studies of RNA virus that can cause influenza, hepatitis, HIV, and Keshan disease. Coronavirus that causes the common cold and COVID-19 infections also belongs to the group of RNA virus and has a unique ability to mutate. Three new mutated virus types have been found in mink and stand in the way of a future vaccine. Therefore, we are forced to bolster our immune defense, which is designed to attack virus from different angles. Still, even if we eat a healthy diet it can be challenging to get enough selenium, and that is why an increasing number of international researchers now recommend selenium supplements to help fight coronavirus.

Millions of people take painkillers such as Panadol or Calpol that contain paracetamol, and an estimated one billion people or so lack selenium due to nutrient-depleted farmland. This is an unfortunate cocktail because being deficient of selenium increases the risk of using paracetamol, so even the recommended dosage burdens the liver to such an extent that it causes toxicity and increase the risk of side effects. This was demonstrated in a collaborative study carried out by Bath University in England and Southwest University in China.

– and could even make them more dangerous

Selenium is of vital importance to a strong immune defense. Still, selenium deficiency is a common problem and it increases the risk of viral infections such as influenza and the coronavirus from China, which is feared to turn into a global pandemic. It is a problem that selenium deficiency in infected animals and humans causes the virus to mutate and become more aggressive. Because of selenium’s important role as a powerful antioxidant, being deficient of this micronutrient may leave the body vulnerable to oxidative stress, which can cause tissue damage and complicate the virus infection. It is therefore important to get enough selenium at all times, as it also increases our resistance towards other viral infections such as herpes, HIV, and hepatitis, according to an article published in Nutrients.

Hashimoto’s disease (Hashimoto’s thyroiditis) is an overlooked scourge that leads to hypothyroidism and is particularly widespread among women. Postpartum thyroiditis that also slows down your metabolism follows in the wake of pregnancy. Graves’ disease where the metabolism speeds up (hyperthyroidism) is less common. These three thyroid disorders belong to the group of autoimmune disorders where the immune defense attacks the body’s tissues, and it appears that lack of vitamin D increases the risk, as it controls the immune defense in a number of ways. According to a new review article that is published in Nutrients, taking larger quantities of vitamin D may have a positive impact on these thyroid disorders.

Having too little selenoprotein P in your blood increases the risk of heart failure, according to a Swedish population study, in which the authors look closer at selenoprotein P’s role as a marker of the body’s selenium status and as a precursor of other selenoproteins. We need more than 100 micrograms of selenium daily to properly saturate selenoprotein P, but because the European soil is low in selenium it is difficult to get enough from the diet.

Congenital heart defects are the most common birth defect on a global scale. The condition is associated with a number of different complications and even comes with an increased risk of infant death. Maternal nutritional status is vital for the development of the fetus, and a team of Chinese scientists has looked closer at how selenium, zinc, and copper affect the development of the disease. They found that a relatively high intake of selenium and zinc lowers the risk of congenital heart defects. Therefore, the scientists call for increased focus on these two minerals during pregnancy and advocate the use of supplements.

Earlier studies have found a link between low selenium and overweight, but only few and limited studies have investigated this connection in children. Therefore, Chinese researchers wanted to take a closer look, and selenium levels in nail clippings give a rather accurate picture of the body’s general selenium status. Selenium deficiency is common in many parts of the world, including parts of China and Europe.

An international science team from the University of Surrey in England has found a link between low selenium levels in the soil and the risk od COVID-19 infections becoming lethal. Professor Margaret Rayman, who headed the study, has spent decades studying the global lack of selenium that is known to impair the ability of the immune system to tackle virus infections and new epidemics. The farmlands in large parts of the world, including Europe and China, are low in selenium, and it is vital to have more focus on this essential nutrient.

There are around 750,000 people in Denmark who take several medical drugs per day, and the number of users is on the rise. What many people are unaware of is that different drugs can disrupt the body’s ability to absorb or utilize one or several nutrients, especially things like B vitamins, vitamin C, vitamin D, vitamin K2, magnesium, potassium, calcium, zinc, iron, and coenzyme Q10. It is therefore vital to get sufficient amounts of the mentioned nutrients to reduce the risk of adverse effects.

- and that increases the need for selenium

Selenium is necessary for ensuring proper functioning of around 25 different enzymes – also known as selenoproteins – that are essential for energy turnover, metabolism, immune defense, fertility, and for antioxidant protection to help prevent cells and DNA from being damaged by oxidative stress. Selenium is also a so-called mercury antagonist that works by attaching itself to mercury, thereby preventing mercury’s harmful impact on the brain and nervous system. Once selenium has attached to mercury, however, it is no longer available to carry out all of its essential functions in the body. Because we are all exposed to mercury in some degree, this may cause a relative selenium deficiency that leaves our brain and nervous system particularly vulnerable to oxidative damage. In a new review article based on published research, Professor Nicholas V.C. Ralston and Dr. Laura J. Raymond explain why the toxic damage to the brain and nervous system is primarily a result of mercury’s inhibiting impact on the selenium metabolism. Selenium deficiencies are rather common, and mercury poisoning is an insidious problem, so the combination of these two problems deserves a lot more attention.

The majority of supplements with vitamins and minerals fails to extend life or protect against cardiovascular disease, although fish oil does seem to have a good effect, according to a large review from John Hopkins University. On the other hand, a Danish study shows that blood levels of vitamin D are crucial for a person’s expected lifespan, and a groundbreaking Swedish study shows that patented supplements with Q10 and selenium benefit older people by improving their cardiac health and reducing cardiovascular mortality by 50%. What matters is to use supplements that contain nutrients in the right quantity, which have a proper quality and can be absorbed by the body. In the following, you can read more about the different studies and learn how you can improve your heart health and increase your chances of a longer life.

- with four key nutrients

Your birth attest reveals your actual age but your biological age gives a more accurate picture of your health and life expectancy. Our biological age and cardiovascular health are closely connected, with atherosclerosis and arterial stiffness representing a progressive process that eventually leads to the majority of deaths. Nonetheless, you can do a lot yourself by making sure to get sufficient amounts the nutrients that are most vital for good cardiovascular health. In this article, we will look closer at some current studies of vitamin K2, Q10, selenium, and omega-3, all of which are essential nutrients that prevent, each in their own way, atherosclerosis, arterial stiffness, and premature death as a result of having high heart age.

Although the course of disease for most people with COVID-19 is rather mild, the greatest concern is the life-threatening complications in the respiratory tract caused by oxidative stress and cytokine storm where the immune system attacks healthy tissue. Scientists are busy looking for new therapies such as intravenous vitamin C that is about to be tested in a new Chinese placebo-controlled study, according to an article that is published in Critical Care. Several researchers say that vitamin C from dietary sources and supplements has a preventive effect because it strengthens and regulates the immune defense in the respiratory tract. The same is the case with vitamin D and selenium.

- but specific nutrients protect you

People, who eat nutrient-depleted diets, have an increased risk of contracting cancer, according to a French study that is published in PLoS Medicine. The scientists therefore recommend labeling food to help consumers make healthier choices. In the Nordic countries, we already have the “Keyhole label” on certain healthy food items, but even if you follow the official dietary guidelines, it may be difficult to get enough vitamin D and selenium, both of which are nutrients with several anti-cancer mechanisms.

- that you can correct with diet changes and supplements

PCOS – or polycystic ovary syndrome – is a problem that occurs in 5-10 percent of women of childbearing age. It is the most common cause of involuntary infertility. Related symptoms include tiredness, hirsutism (male hair growth), acne, and irregular menstrual periods. PCOS is often linked to instable blood sugar, increased risk of insulin resistance, overweight, cardiovascular disease, type 2 diabetes, and autoimmune diseases like Hashimoto’s thyroiditis that causes slow metabolism. Diet and exercise mean a lot in terms of prevention and treatment. The same is the case with different vitamins and minerals. We will be looking closer at B vitamins, vitamin D, vitamin E, and coenzyme Q10, plus magnesium, zinc, selenium, chromium, iodine, and fish oil. We will also be looking at how relevant supplements, according to science, can help control blood sugar levels and the hormone balance.

During pregnancy, the unborn child needs different nutrients for proper development of its brain and nervous system. Even if the mother eats a balanced diet, it can be difficult to get enough selenium for a number of reasons. In a new Italian animal study that is published in Nutrients, scientists have looked closer at selenium’s role during pregnancy and lactation. They observed that even minor selenium deficiencies can have a negative effect on the offspring’s brain development and behavior. This study supports earlier human studies showing how vital it is for the mother to get plenty of selenium during pregnancy and breastfeeding.

Most people thrive on the idea of staying physically active throughout life, but as we grow older, our skeletal muscle slowly vanishes and our figure changes. This is known as sarcopenia and is one of the main reasons why older people become more fragile and perhaps even disabled. Exercise and diet play a major role, and it seems that the official dietary guidelines are not optimal and should focus more on increased intake of protein as well as lysine, vitamin D, and omega-3 according to a new Canadian study. Earlier research shows that magnesium, selenium, and Q10 are also important for muscle mass and strength.

A previous study has demonstrated that daily supplementation with coenzyme Q10 and selenium increases heart muscle strength in seniors and reduces their cardiovascular mortality by over 50 percent. Now, a team of Swedish and Norwegian scientists has found that these two nutrients are also able to slow down the age-related shortening of cellular telomeres, which are attached to the ends of all DNA strands. You can compare telomeres to the small aglets that prevent our shoelaces from fraying and tangling. Like aglets, telomeres protect the DNA strands, but they are exposed to attrition and eventually wear out. The more worn our telomeres become, the more exposed the cellular DNA becomes, until it reaches the point where the cell finally perishes. Q10 and selenium appear to preserve telomere length, thereby keeping us in good health for longer time.

- but only when taken in optimal amounts

Q10 is a popular supplement for boosting energy levels and supporting circulatory health. According to a new meta-analysis that is published in Molecular Nutrition Food Research, the compound is also able to inhibit inflammation, which is the common thread in most chronic diseases. This requires sufficiently high doses of the compound, and it is also important to take high-quality supplements with documented absorption.

Cardiovascular diseases are widespread and one of the major causes of death. The risk is increased by factors such as ageing, diabetes, and overweight. One of the underlying causes is oxidative stress, which is an imbalance between free radicals and antioxidants. Q10, which is involved in cellular energy turnover, happens to be one of the most powerful antioxidants. According to a review article that is published in the scientific journal Antioxidants, supplementation with Q10 can reduce oxidative stress and cardiovascular mortality. It can also improve quality of life and increase the chances of survival. Generally speaking, Q10 has a huge potential for anyone with a desire to remain healthy, and it is important to choose a supplement with documented quality and bioavailability.

The immune system needs selenium every single day. Lack of this nutrient increases your risk of virus infections, inflammation, and cancer. It is a huge problem that many of us get too little selenium because of factors such as nutrient-depleted soil and unhealthy eating habits.

- and there are no side effects

Rheumatism is the most widespread chronic disease in Denmark, and many people experience a worsening of the symptoms during the winter period. The majority of people take anti-inflammatory drugs for years, but this increases their risk of bleeding stomach ulcers and other side effects, not to mention premature death. The underlying cause is chronic inflammation and it is a problem that is not properly addressed. For decades, Nobel Prize-winners and other scientists have revealed what causes chronic inflammation and how the problem in many cases can be helped with various supplements that help cure the pain. In the following, we have summarized a lot of the research that has been conducted with vitamin D, fish oil, magnesium, selenium, zinc, and glucosamine, and we have looked at why the anti-inflammatory lifestyle has become such a health trend. It is essential to use supplements that contain the different ingredients in therapeutic doses and with a quality that allows the body to absorb and utilize the active compounds.

The cells in our body are constantly renewed but they can only divide a limited number of times. It all depends on the length of their telomeres, which one can compare to the protective plastic tips at the ends of shoelaces. Every time a cell divides, its telomeres are reduced in length, bringing the cell closer to its terminal phase. Now, a Chinese study has revealed that higher selenium intake is linked to increased telomere length. Put differently, a higher selenium intake contributes to protecting the cells and allowing them to replicate more times. This may likely postpone the ageing process and extend our lifespan, and there are other studies that suggest the same. It is worth making a note of the fact that selenium deficiency is widespread in Europe and throughout the world.

Colorectal cancer is one of the most common cancer types. Although the diet is of huge importance, the understanding of minerals and their interactions and preventative effect is limited. Earlier studies have shown that calcium and selenium have protective roles. It also looks as if having more selenium in the blood can improve the effect of calcium. This was demonstrated in a new Polish study that is published in BMC Nutrition. The scientists point out that there is widespread selenium deficiency in Europe and that supplementation may be needed.

The way in which selenium and iodine interact is determining for the thyroid gland and the metabolism. A deficiency of one or both nutrients coupled with exposure to environmental toxins may have grave consequences and contribute to some of the most commonly occurring metabolic disorders.

Prostate cancer is the most common cancer form among men. In terms of existing therapies, there is room for improvement. According to a Polish study that is published in Nutrients, higher levels of selenium and zinc in the blood can improve survival. The study authors mention that these two nutrients also protect against other cancer forms.

There is a growing interest among scientists in selenium’s role in the brain and nervous system, and a placebo-controlled study published in Frontiers in Nutrition shows that seleniumsupplementation is useful as an adjuvant in migraine therapy. The study authors describe that oxidative stress may involved in migraine attacks and mention that selenium has a protective effect due to its role as an antioxidant. Earlier studies have shown that other antioxidants like Q10 and magnesium also have a therapeutic value by way of other mechanisms that may work synergistically.

It’s commonly known that physical activity boosts the brain’s ability to form new brain cells – or neurons. Still, the underlying mechanisms have been a mystery to science. A team of Australian scientists, however, has recently discovered that, during exercise, mice produce a selenium-containing protein that helps the brain synthesize new brain cells. The scientists consider this to be a rather fantastic study, and it is assumed that selenium therapy may be used in the future to prevent and treat cognitive decline in people who are unable to carry out physical exercise or in those likely to be selenium-deficient. This is particularly relevant for Alzheimer’s patients and people who have suffered a stroke. It should be added that it can be quite a challenge to get enough selenium from an otherwise balanced diet in our part of the world.

- by way of different mechanisms

There seems to be a relation between ageing, Alzheimer’s disease, and the widespread problems with selenium deficiency. According to a new study that is published in Antioxidants, scientist have revealed how different selenium-containing proteins can affect pathological processes in the brain that are known to cause Alzheimer’s disease. They believe selenium may have therapeutical potential in the treatment of this disease, which is one of the greatest disease burdens and a leading cause of death among seniors. Selenium also helps in the prevention of the disease, which is extremely important because it is often difficult to diagnose Alzheimer’s disease in its early stages.

Graves’ disease, also known as Basedow’s disease, is caused by hyperthyroidism and is associated with a number of different symptoms. A lot of patients also develop Graves’ ophthalmology, a disorder that can result in bulging eyes and impaired vision in severe cases. Apparently, daily supplementation with 200 micrograms of selenium has a positive impact on the eyes and their appearance, according to a Thai study that is published in Orbit.

Although cancer treatments have improved drastically, science has still not managed to break the curve. On the contrary. A growing number of people contract cancer, and that is why we should focus more on the trace element, selenium, which possesses several mechanisms against cancer. However, it requires that we get enough selenium and that is in a form that the body is able to utilize optimally.

Selenium is an essential trace element of vital importance to our general health. The nutrient is also important for our gut flora, and being selenium-deficient may increase the risk of irritable bowel syndrome, inflammatory gut diseases like Crohn’s disease and ulcerous colitis, and even bowel cancer. Our intestine is also called our “third brain” because both our gut flora and digestion have a significant influence on our mental well-being, according to a review article published in Frontiers in Nutrition. The authors focus on selenium because selenium deficiencies are common in China, Europe, and many other places, and supplementation may be necessary.

Selenium is a trace element with a number of essential functions. An estimated one billion people worldwide get too little dietary selenium. The problem is mainly a result of nutrient-depleted farmland. Moreover, blood levels of selenium drop drastically in connection with COVID-19 infections, serious illness, and pregnancy because the body has an increased need for the nutrient. Altogether, selenium deficiency increases the risk of complicated COVID-19 infections, autoimmune diseases such as rheumatoid arthritis, Hashimoto’s thyroiditis, preterm delivery, and miscarriage. Supplementation may help optimize blood levels of selenium, which can be relevant for preventing and treating a number of common diseases, according to an article that is published in International Journal of Medical Sciences.

Lack of selenium, an essential trace element, may cause thyroid disorders, cardiovascular disease, virus infections, AIDS, infertility, neurological disturbances, and cancer. An estimated one billion people worldwide are selenium-deficient. This is mainly a result of nutrient-depleted soil, which is a real problem in places like Europe. For decades, scientists have been warning about this problem, and a lot suggests that we need more than the officially recommended intake to protect ourselves effectively against disease, according to a review article published in StatPearls.

Hypertension and other cardiovascular diseases account for the majority of deaths. Diet and lifestyle are highly relevant, and it also appears that there is a significant linear relation between selenium intake and the risk of developing hypertension, according to a population study published in Frontiers in Immunology. The authors also mention selenium’s role in relation to blood pressure, and because seleniumdeficiencies are quite common, we need to look closer at this relation.

Cataracts is one of the leading causes of vision impairment and blindness. The risk is increased by old age and diabetes. According to a new study that is published in Frontiers in Nutrition, a relatively high selenium intake can protect against the disease. The scientists mention that because of selenium’s unique antioxidant properties this nutrient protects the cells in the eye and in other places against free radical damage and oxidative stress.

Selenium is crucial for your thyroid function, immune system, cardiovascular system, and even for preventing cancer. Fish and shellfish are among the best selenium sources, but even 200 grams of fish and shellfish five days a week won’t do the trick, according to a Danish selenium study. What makes it even more difficult to obtain optimal amounts of this nutrient is that the agricultural soil in large parts of Europe is stripped of vital nutrients like selenium. Margaret P. Rayman, one of Europe’s leading experts on selenium, says that there is a direct link between the decreasing selenium intake and the increasing rate of cancers, rheumatism, infertility, and numerous other health problems. The question is, how do we humans get enough selenium?

Everybody is exposed to heavy metals and other environmental toxins. They are present in the water, the air, our diet, in cosmetics, tobacco smoke, medicine, and countless other sources. These toxins increase our risk of cancer, neurological disorders, thyroid disease, autoimmune disease, and numerous other health problems. Also, the combination of different toxins causes a “cocktail effect” that we know very little about. According to a Spanish study of mice, which is published in Science of The Total Environment, a selenium-enriched diet has a protective effect.

We all get exposed to mercury, a neurotoxin that is found to a great extent in nature and in our environment. According to an EU report, mercury is a large economic burden to society because of the costs related to lowered IQ levels. For that reason alone, we should aim to limit our exposure to mercury and also take a closer look at how selenium protects against the harmful heavy metal – provided our selenium levels are adequately high.

Selenium is a constituent of at least 25 essential proteins (selenoproteins), including several antioxidants that protect cells against oxidative stress and disease. A team of researchers from Munich in Germany has mapped out the mechanisms, which the selenium-containing antioxidants use to protect neurons in the brain against cell death. The scientists see a whole new potential with selenium because of its ability to protect against neurological disorders and cancer. It is problematic, however, that we have widespread selenium deficiency in our part of the world. Even if you stick with the official dietary guidelines, it is very difficult to get enough selenium to saturate all the different selenoproteins.

The rate of inflammatory bowel diseases like ulcerous colitis is growing, and diet plays a major role. Even if you eat a healthy diet, it can be a challenge to get enough selenium because of the selenium-depleted soil in our part of the world. Apparently, selenium supplementation can lower the disease activity and improve quality of life in patients with ulcerous colitis.

Selenium is involved in a number of different metabolic processes and works as an antioxidant, which protects the heart and cardiovascular system, but it is difficult to get enough of the nutrient from the diet. According to a new American mouse study, selenium supplementation can speed up the metabolic processes and protect against overweight. A Swedish study of seniors published some time ago showed that supplements of selenium and Q10 has a positive effect on quality of life and lifespan.

The brain is particularly vulnerable towards oxidative stress and local inflammation that can set the stage for Alzheimer’s disease and other neurological conditions. However, it turns out that certain selenium-containing antioxidants are able to protect the brain neurons against damage. Also, selenium supplements can improve cognitive performance in patients suffering from mild cognitive impairment and Alzheimer’s disease, according to a meta-analysis that is published in Nutrients.

- and routine screening is not enough

Cancer in the colon and rectum is rather common. One in 20 Danes gets colon cancer at some point in life. Since 2014, the Danish Health Authority has recommended a screening program, offering middle-aged and older people a screening for colon cancer every other year. If the disease is discovered in its early stage, the chances of successful treatment increase. Supplementation with organic selenium yeast has been shown to lower the risk of colorectal cancer in the first place, and selenium even has a protective effect against other cancer forms, so the nutrient is an essential part of the prevention. The problem is that selenium deficiencies are so common as a result of our nutrient-depleted soil.

 – and why it is vital to get the exact right amount!

All our cells contain different selenium compounds that support a number of vital functions, and which have several cancer-fighting mechanisms. As an antioxidant, selenium prevents iron from developing some of the most harmful free radicals that can damage cellular DNA and lead to uncontrolled cell division. This is why a selenium deficiency combined with excess iron is a lethal cocktail. Although iron is essential, it is vital that we do not get too much. It is also important to get plenty of selenium from food and/or supplements and in a form that the body can absorb and utilize in each and every cell in order to be properly protected against cancerous substances.

Involuntary childlessness has become increasingly common. Many women find themselves in a race against time, and their biological clock keeps ticking louder and louder. Fertility therapies, miscarriages, preeclampsia, and other complications during pregnancy contribute to the physical and emotional burden. In a new Australian study that is published in Nutrients, the authors write about selenium and zinc and how these nutrients play an important role in fertility and a healthy pregnancy. They also address the problems with widespread selenium deficiency and point out that environmental toxins like mercury deplete levels of vital selenium-containing proteins in the body. The scientists point to supplements for fighting deficiencies, just like folic acid and iron are routinely recommended to pregnant women. It pays off to choose selenium yeast with multiple organic selenium compounds and organic zinc to help improve the bioavailability and utilization of the nutrients.

Cancer has become one of the leading causes of death, with rates going up every year. The diet plays a major role and there is a lot of focus on seleniumas an anti-cancer agent – both in the form of selenium-enriched functional foods and selenium supplements. Around one billion people worldwide are believed to lack selenium. According to a review article that is published in Foods, however, taking a daily supplement of 100-200 micrograms of selenium yeast can prevent deficiency and reduce some of the most common cancers by fifty percent.

Seleniumis an essential trace element that affects the rate and development of several cancer types, including cervical cancer that is one of the most common cancer forms. Cervical cancer is often treated with a combination of radiation and chemotherapy and the side effects are known to affect the bone marrow and the formation of blood platelets and blood cells. However, supplementation with selenium yeast appears to counteract these adverse effects without interfering with the treatment, according to a study that is published in Frontiers in Nutrition.

The corona crisis has shed new light on the importance of having a strong immune defense, one that protects us against virus infections in the long run. Selenium plays a vital role for a number of different reasons but, unfortunately, there is widespread deficiency which increases the risk of infections and related complications. In a new review article that is published in International Journal of Molecular Sciences, the authors look closer at selenium’s role in connection with different types of virus infections such as influenza, HIV, and hepatitis with particular focus on COVID-19. The purpose of their article is to inform about new nutritional strategies that may contribute to a strong and well-functioning immune defense – mainly when it comes to COVID-19 and virus types that tend to mutate all the time.

Selenium supports a variety of different selenoproteins and antioxidants that are important for our immune defense, circulatory system, cancer protection, metabolism, gut flora, fertility, nervous system, and general health. This is described in two meta-analyses that are published in Frontiers in Nutrition. The authors mention that there is widespread selenium deficiency in large parts of the world, Europe included, and that this is a public health problem. The big question is how much selenium we need to effectively prevent and treat many chronic illnesses.

Selenium has an overlooked role in sperm quality and healthy pregnancies. A team of scientists from Romania has looked closer at blood levels of different selenium-containing antioxidants and found that low levels are significantly correlated with poor sperm quality. The scientists also explain that lack of selenium increases the risk of pregnancy-related complications, miscarriage, and preterm delivery. Both selenium deficiencies and infertility are common problems so selenium supplementation may be worth considering. For decades, Danish farmers have added selenium to animal fodder as a way of improving the fertility and general health of the animals.
