- 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.

A lot of sports and fitness disciplines are indoor activities. According to a new American study, this increases the risk of becoming vitamin D-deficient. Not only can a vitamin D deficiency hamper your performance, it can also increase your risk of acute infections, chronic inflammation, osteoporosis, cancer, and a number of other health problems. To make matters worse, people living at northern latitudes can only synthesize vitamin D in their skin during the summer period where the sun sits high in the sky, and the body’s vitamin D stores are limited during the winter period.

If you have a large waist circumference, you are more likely to have low blood levels of vitamin D, according to a study that was presented at the annual meeting of the European Society of Endocrinology (ESE) in Barcelona in 2018. The researchers therefore suggest that overweight individuals with a large waist circumference have their vitamin D levels measured, as this may help prevent many of the health problems that are linked to low vitamin D levels, including such things as an increased risk of infections, cardiovascular disease, osteoporosis, winter depression, blood sugar irregularities, diabetes, autoimmune diseases, and 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.

It is no coincidence that sclerosis is more prevalent at the northern latitudes. A major factor is lack of vitamin D, a nutrient that we only synthesize from sunlight during the summer. A new study published in the scientific journal Neurology shows that the risk increases even more if people are overweight, and children are particularly vulnerable. As part of the strategy for preventing sclerosis, we must pay more attention to weight management and make sure to get plenty of vitamin D all year round and throughout life. Furthermore, various campaigns that warn against sun exposure and recommend the use of sunscreen should at the same time advise children and adults how to get enough vitamin D from other sources.

Taking a supplement of vitamin D in combination with your prescription asthma medicine may halve your risk of an asthma attack that would require hospitalization, according to a new meta-analysis from Queen Mary University in London (QMUL). A vitamin D deficiency alone, which is rather common at northern latitudes, can increase the risk of asthma. Therefore, it is vital to make sure to have sufficiently high levels of this nutrient all year round to protect your respiratory tract.

According to a new study from Johns Hopkins University in the United States, vitamin D is able to protect overweight children against asthma caused by urban air pollution. Sunshine during the summer period is the main source of vitamin D, but due to our modern lifestyles, many people, including children, fail to get enough of the nutrient. This may have widespread consequences, as lack of vitamin D also increases the risk of overweight.

Most cells in the human body need vitamin D. The nutrient also has an important role in preventing symptoms and diseases that may occur after menopause – including osteoporosis, muscle weakness, dry mucosa, mood swings, cardiovascular disease, type 2 diabetes, and cancer. In an article that is published in Frontiers in Physiology, the authors address the widespread vitamin D deficiency that is an overlooked problem in post-menopausal women, and they suggest striving to have optimal vitamin D levels in the blood throughout life.

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?

It has been known for a long time that a lack of vitamin D increases your risk of overweight. Now, an Italian study gives a whole new view on low vitamin D and how it is linked to elevated levels of TMAO (Trimethylamine N-oxide), a metabolite that increases the risk of non-alcoholic fatty liver and accompanying complications such as insulin resistance, diabetes, and cardiovascular disease. The scientists also looked at the gut flora’s and the liver’s roles in TMAO production and the fact that low vitamin D levels and overweight are a vicious cycle. It appears that overweight people need more vitamin D than the recommended level. In terms of non-alcoholic fatty liver, we will also be looking at the controversial delicacy, foie gras, and the fact that carbohydrate overconsumption burdens your liver.

A new British study that is published in British Journal of Nutrition shows that getting too little vitamin D during pregnancy has a negative effect on the social development and motor skills of the toddler. Vitamin D is believed to play a role in brain development. It is vital for the pregnant mother to pay careful attention to getting enough vitamin D all year round, as our modern lifestyle with indoor activities, our frequent use of sunscreen with high sun factor, being overweight, and having dark skin contribute to the widespread deficiency of this nutrient.

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.

- which your brain, nervous system, and liver need

A cold beer with lunch or a glass of red wine to go with your steak may be tempting. In fact, alcohol in limited amounts can be relaxing and it provides beneficial antioxidants. However, Danes drink too much, and our excessive alcohol consumption is one of the worst threats to public health. Many alcoholics suffer from unstable blood sugar levels, which can have a rather bad impact on their willpower. In addition, the empty calories deplete the body’s levels of vitamins, minerals, and essential fatty acids, on which the nervous system, the brain, and the liver depend. This can easily turn into a vicious cycle. Therefore, having stable blood sugar and making sure to get plenty of vital nutrients is important for preventing and treating alcohol abuse.

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.

Lack of vitamin D is rather common and taking large quantities of the nutrient can not only protect against virus infections like COVID-19 but even counteract the life-threatening complications in those affected with the disease, according to a new, comprehensive, Irish report (TILDA) from Trinity College Dublin (University of Dublin in Ireland). The TILDA report supports many other published studies showing that the immune system is unable to function without vitamin D. The main focus in the battle against COVID-19 is hygiene, isolation, and delayed immunization with vaccines. However, it is also essential to bolster the immune defense, as this determines the difference between being able to ward off the infection, suffer mild symptoms only, or succumb. The scientists recommend that all adults take a high-dosed vitamin D supplement, especially older people, nursing home residents, chronically ill people, hospital patients, health professionals and other exposed groups. That way, we are better protected against future epidemics.

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.

All the different awareness campaigns for sustainability and eating plant-based diets have inspired more and more people to become vegetarians or vegans. However, there are health aspects that need attention. Vegetarians and vegans in particular have lower intakes of protein, vitamin D, and many other essential nutrients, according to a new Spanish study that is published in Nutrients. It is therefore recommended that adult vegetarians and vegans take vitamin D supplements to counter their risk of osteoporosis and other diseases related to vitamin D deficiencies.

Melanoma is a type of malignant skin cancer that spreads rapidly. Being vitamin D-deficient doubles the risk of dying of the disease, according to a Spanish study that was presented at the European Academy of Dermatology and Venereology congress. It is commonly known that sunburns, which one should generally avoid, increase the risk of contracting skin cancer. But we must not forget that the summer sun is our main source of vitamin Dand at our latitude, it necessary to take a vitamin D supplement in the wintertime. People who avoid the sun or have difficulty with synthesizing vitamin D in their skin should take a supplement all year round.

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.

Blood levels of vitamin D serve as an early indicator of future health problems such as cardiovascular disease, osteoporosis, and cancer, according to a review article that was presented recently to the European Society of Endocrinology. Lack of vitamin D is rather common and a threat to public health, which is why the scientists suggest measuring levels of total vitamin D and free vitamin D in the blood. By optimizing levels of the nutrient in the blood it is possible to prevent a host of different lifestyle diseases as well as early death. It is not enough just to take any random vitamin D supplement. It must contain the right dose and have good absorption in order to be able to optimize vitamin D levels in the blood.

Type 2 diabetes is spreading like a bushfire. An alarmingly many people have metabolic syndrome – or pre-diabetes – which is characterized by insulin resistance, hypertension, elevated cholesterol levels and abdominal obesity (apple-shaped body). Type 2 diabetes and metabolic syndrome are associated with enormous human and socio-economic costs. In this article, we will look closer at chromium, vitamin D, magnesium, and coenzyme Q10 plus relevant diet changes to see how they can positively affect blood sugar levels, cholesterol balance, and weight control. We will also take a closer look at supplements that are able to prevent diabetic neuropathy, a disorder that can lead to amputations.

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.

Allergic diseases such as asthma, hay fever, food allergies and contact dermatitis are becoming increasingly common. It makes a big difference to breastfeed for at least six months because breast milk contains various compounds that strengthen the child’s gut flora and immune defense. Vitamin D supplements are also important, and Icelandic research suggests that is pays off to continue giving them to children until the age of six years. Unfortunately, many parents forget to give their children vitamin D until the age of two, as recommended. Also, many children get too little sunlight during the summer period and don’t get vitamin D supplements when it is winter, and that is something we all need at these latitudes.

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.

According to a British population study, this seems to be the case. At the same time, it’s alarming that vitamin D deficiency is such a widespread problem and that Alzheimer’s disease and other typers of dementia are on the rise, because there is most likely a connection. How does vitamin D affect brain health, and how much vitamin D do we need to help nerve cells and cells in general function optimally?

Around 25 percent of adults have had canker sores, also referred to as recurrent aphthous stomatitis (RAS). The condition is characterized by painful, superficial sores, and we don’t know all that much about what causes it or how to treat it. However, according to a meta-analysis that is published in Frontiers in Nutrition, a possible cause may be low blood levels of vitamin D, a nutrient with a key role in oral health and immune defense.

Children and youngsters who are exposed to lots of sunlight and have plenty of vitamin D in their blood are much less likely to develop sclerosis later in life, according to a new study. In fact, there is a reason why sclerosis is more prevalent at northern latitudes. During the winter, the sun sits too low in the sky for us humans to be able to synthesize vitamin D in the skin. However, one must also realize that the intensified use of sunscreen can block the skin’s production of vitamin D. It is therefore essential to get plenty of vitamin D from sun exposure or to take a vitamin D supplement, as this may help prevent diseases such as sclerosis that take years to develop.

The quality of the diet plays a particularly great role in the first years of a child’s life. The different nutrients help prevent obesity, diabetes, and other chronic diseases later in life. However, modern diet and lifestyle have resulted in widespread deficiency of vitamin D, iodine, iron, calcium, and magnesium among children, and that has had serious consequences for their physical and mental health, according to a large German study published in Frontiers in Nutrition. The scientists therefore recommend increased focus on the nutritional status of children and supplementation throughout childhood, if necessary.

A chronic cough often follows in the wake of virus infections such as colds, influenza, and COVID-19. Lack of vitamin D seems to be a major contributor, coupled with the fact that a vitamin D deficiency often increases during the disease period. Vitamin D is of vital importance to a strong immune defense and also helps to regulate inflammation. Therefore, supplementation with vitamin D may be worth considering as a way of preventing virus infections and treating complications such as chronic cough, according to two studies that are published in European Respiratory Journal.

Headache, aching joints, and other types of chronic pain are typically caused by myofascial pain syndrome, which is characterized by localized pain. There can be many underlying causes of this condition, but according to a Thai study published in BMC Nutrition, lack of sunshine and too little vitamin D are quite common among patients. Magnesium therapy may also have an effect, according to a study published in BMC Oral Health.

The number of seniors is on the rise and so is the number of older people with cognitive decline and dementia. It is a huge health burden and not enough is done to prevent it. According to a large population study published in Frontiers in Nutrition, widespread problems with vitamin D deficiency combined with too little physical activity contribute significantly to an increased risk of cognitive decline and dementia in old age. The authors describe the important interaction between vitamin D and exercise, which is vital for brain health and cognitive health.

According to a new study based on a number of systematic reviews and meta-analyses, the widespread lack of vitamin D increases the risk of being infected with COVID-19. It also increases the risk of complications and death as the result of a derailed immune defense. At the same time, supplementation with vitamin D appears to reduce both disease severity and death among COVID-19 patients, provided blood levels of the nutrient are optimal.

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.

- an overlooked connection

When it comes to battling COVID-19, the main focus is on hygiene, face masks, lockdown, and delayed vaccines. For several months, scientists have urged people to take vitamin D supplements during the winter period as a way of preventing new waves of COVID-19. This is because vitamin D is of vital importance for a well-functioning immune system and it is known that deficiencies of this nutrient contribute to the spread of seasonal virus infections. We also see that groups of people that are most likely to be vitamin D-deficient – including seniors, nursing home residents, people with dark skin, overweight individuals, diabetics, and those with chronic diseases – are most vulnerable towards COVID-19. The British government is already handing out vitamin D supplements to exposed groups, according to an article in Daily Mail and a review article that is published in British Medical Journal. But why is vitamin D so important for the immune defense, why are some people more likely to become deficient, and how much vitamin D do we actually need? Also, will vaccines cut the mustard if COVID-19 mutates?

- so make sure to get enough of the nutrient during the winter period

COVID-19 is highly unpredictable and be either totally harmless or life-threatening. Scientists from Oak Ridge National Laboratory in Tennessee recently made a comprehensive genetic analysis that reveals a new hypothesis – the bradykinin hypothesis – which shows why COVID-19 attacks the way it does, why symptoms vary, and why some groups of people are more vulnerable than others. The hypothesis also underpins the importance of getting enough vitamin D to prevent or possibly treat the disease. Vitamin D deficiency in the winter period is quite common and that may pave the road for new rounds of COVID-19 and an increased risk of complications.

It has already been documented that the widespread problems with vitamin D deficiency increase the risk of being infected with COVID-19 and developing life-threatening complications. In a new study, a team of Turkish scientists has demonstrated that swift treatment with vitamin D can shorten the length of hospital stays plus reduce mortality risk by 50 percent. What’s more, it even has a positive effect on comorbidity. Vitamin D deficiencies are especially common during the winter period and among seniors, people of color, overweight individuals, diabetics, and other vulnerable groups. This makes the study results very relevant, especially when you consider the fact that vaccines only have a limited effect.

Since December of 2021, two large meta-analyses have revealed that having low levels of vitamin D in your blood increases the risk of COVID-19 infections, severe disease, admission to intensive care, and death. A third meta-analysis has shown that only 12 percent of COVID-19 patients who took supplements of vitamin D were admitted to intensive care, compared to 26 percent of the non-supplemented. Finally, a fourth meta-analysis shows that supplementation with vitamin D significantly lowers the risk of life-threatening COVID-19 infections. This is particularly relevant during the winter period and among people at risk of being vitamin D-deficient, including groups such as seniors, people with dark skin, overweight people, and the chronically ill. There is an alarming need for increased focus on vitamin D supplements to prevent and treat COVID-19 and other virus infections by optimizing blood levels of the nutrient. It is also important to get plenty of magnesium, a nutrient the body needs to activate vitamin D.

Vitamin Dis important for a swift and effective immune response. Once COVID-19 infections become complicated and life-threatening, it is not the virus that is the threat but the fact that the immune defense reacts too slowly and then causes hyperinflammation that damages healthy tissues in the respiratory system and circulatory system.
French scientists have made a meta-analysis where they looked at the relation between vitamin D levels in the elderly and COVID-19. Their review revealed that lack of vitamin D increases the infection risk and makes it more likely that the infections become complicated and life-threatening. Vitamin D deficiency is common among older people and for that reason, the researchers recommend vitamin D supplements as an inexpensive strategy for prevention and as a supplementary source of treatment.

According to a retrospective study of older COVID-19 patients, lack of vitamin D is linked to serious lung symptoms, longer disease duration, and increased risk of death. The problem is made worse by the fact that vitamin D deficiencies are so common among older people, nursing home residents, and exposed population groups. According to a new study published in Nutrients, doctors and scientists advise governments worldwide to include vitamin D supplementation in their campaigns and strategies for fighting COVID-19 and mutations of the virus. The study supports earlier research showing that lack of vitamin D is a risk factor for all age groups. The question is how much vitamin D does one need to have optimal levels of the nutrient in the blood?

- how to find the best alternatives for strong bones

Many people avoid dairy products because they are lactose intolerant, are vegan, or for other reasons. Milk is a good source of nutrients, especially calcium, but you can easily get enough calcium from other food sources. What is more, it appears that vitamin D, vitamin K2, and the calcium/magnesium ratio is even more important than calcium alone for the structure and maintenance of strong bones. Another thing to remember is that sugar, soft drinks, stimulants, and certain types of medicine can disrupt the bone-building processes. Therefore, having strong bones is about a lot more than dairy products and calcium alone. Finally, don’t forget that daily weight-bearing exercise stimulates bone density.

The summer sun is our most important source of vitamin D but people dark-skinned people living at northern latitudes have difficulty when it comes to producing enough of the nutrient. This makes them much more likely to become vitamin D-deficient and that can have serious health consequences, which may be life-threatening in worst case according to several studies.

Vitamin D is of vital importance to a well-functioning immune defense and it protects against virus infections. This has been confirmed by Denmark’s infection control agency, Statens Serum Institut, and researchers from Harvard University in Boston, USA. In a study, the Danish and American scientists found that having low levels of vitamin D in the blood is associated with a greater risk of severe disease outcome in patients with COVID-19.

- 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.

Diabetes is spreading like a bushfire across the globe, but even if governments, doctors, and health authorities have tried desperately to bend the curve, they have not succeeded so far. On the contrary. Today, diabetes is controlled with help from different medical drugs that do not address the underlying cause and actually affect or organ systems. Because of this, diabetics often have impaired quality of life and shorter lifespans than healthy individuals. What is more, diabetics have widespread vitamin B12 and vitamin D deficiencies, which are associated with diabetic neuropathy, which is a serious complication. Cholesterol-lowering drugs (statins) are also linked to reduced levels of Q10, a compound that is necessary for energy turnover, the heart, and the cardiovascular system.

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.

- with non-alcoholic fatty liver disease

Weight-challenged children and teenagers have grown to become a global health threat, and the problem became even worse during the corona pandemic. Overweight is linked to a number of health problems, including non-alcoholic fatty liver disease that sets the stage for type 2 diabetes and other serious ailments. In a new review article that is published in Nutrients, researchers look closer at how a carbohydrate-restricted diet or the traditional Mediterranean diet can help to counteract the development of overweight and non-alcoholic fatty liver disease. Also, supplementation with vitamin E, vitamin D, fish oil, and probiotics can block the development of non-alcoholic fatty liver via different metabolic parameters.

Many men suffer from erectile dysfunction, a problem that often foreshadows cardiovascular disorders. It appears that vitamin D plays a preventive role by way of several mechanisms that can even benefit diabetics, according to a new meta-analysis published in Clinical Nutrition. An earlier study that is published in Clinical Endocrinology shows that vitamin D is involved in the production of male testosterone, which is essential for the ability to obtain and maintain an erection. A man’s sexual performance is therefore highly dependent on his vitamin D levels throughout life.

- that increases your risk of different diseases and premature death

Approximately one billion people worldwide lack vitamin D because they get too little sunlight, they overuse suncream, or they have chronic diseases that prevent proper utilization of the nutrient. This was shown in a new study that is published in The Journal of the American Osteopathic Association. During the summer period, health authorities and organizations issue warnings against the sun and recommend the use of suncream. These campaigns, however, should ideally be accompanied by recommendations on how to get enough vitamin D from other sources. Otherwise, the campaigns may do more harm than good, as all cells in the body need this essential nutrient, and the sun is the single best vitamin D source.

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.

Research conducted over the past decades reveals that vitamin D plays a major role in the brain and nervous system. Now, a Finnish study published in Scientific Reports links vitamin D deficiencies to chronic headaches. Vitamin D deficiencies are becoming increasingly common because we spend too much time indoors. Even during the summer period, it seems that we are unable to produce enough vitamin D because of our exaggerated use of sun cream. Sunlight is the best source of vitamin D and it is therefore important that you expose yourself to enough sunlight to ensure adequate vitamin D synthesis (without getting burned.)

Most people have experienced a normal headache, while migraines are far more complex. Although the pain can be caused by a number of factors, essential nutrients such as B vitamins, vitamin D, magnesium, fish oil, and coenzyme Q10 may play a vital role according to a review article that is published in Current Pain and Headache Reports. The authors describe how certain nutrients affect underlying mechanisms that may prevent or mitigate different types of headaches.

Having sufficient vitamin D in your blood protects you against several cancer forms, according to a new review article that is published in Seminars in Cancer Biology. The summer sun is our primary source of the vitamin, but we can only store a limited amount in the liver for the winter period. The problem is made worse by the fact that we spend too much time indoors, and ageing even increases the risk of chronic vitamin D deficiency. The question is how much vitamin D do we need to protect us against cancer?

The interplay between vitamin D, magnesium, and calcium is vital for bone health and a number of other things, including cancer prevention. According to a new study that is published in American Journal of Clinical Nutrition, high blood levels of vitamin D and magnesium may lower colon cancer patients’ risk of dying of their disease. However, the current recommendations for vitamin D are not enough to reach optimal blood levels of the nutrient. Moreover, it is of vital importance that magnesium is properly balanced with calcium.

Coronary occlusion is the leading cause of death worldwide. Type 2 diabetes is spreading like a bushfire and this disease is characterized by atherosclerosis and early death. Diet and lifestyle are of vital importance and the same goes for vitamin D. According to a new American study that is published in Nutrients, people whose blood levels of vitamin D are above the official threshold levels have fewer biomarkers of cardiovascular disease, type 2 diabetes, and metabolic syndrome.

The immune system cannot function without vitamin D. In fact, blood levels of the nutrient should ideally be higher than the official threshold values for optimal protection against COVID-19 and other respiratory infections, according to a new study from the University of Chicago Medicine that is published in JAMA. An estimated 50 percent or so of the world’s population is believed to lack vitamin D, and people with dark skin are particularly vulnerable. It has been shown in previous studies that the majority of people who test positive for COVID-19 lack vitamin D. Therefore, scientists plan to look at whether daily vitamin D supplementation can help prevent COVID-19 infections or reduce serious symptoms. The researchers mention that it often takes high-dosed supplements to optimize levels of vitamin D in the blood.

- in people aged 60 and older

Cardiovascular disease is the leading cause of death worldwide, and our diet and lifestyle play a major role. According to an Australian study published in British Medical Journal, high-dosed vitamin D supplementation taken for several years lowers the risk of heart attacks or interventions such as angioplasty and by-pass surgery in people aged 60 years and older.

Scientists have discussed for quite some time to what extent vitamin D or omega-3 fatty acids from fish oil are able to lower the risk of a heart attack, stroke, and cancer. Although quite a lot of studies have been conducted in this area, there still is no large-scale clinical population study that includes different races. However, an American study has shown that fish oil supplements lower your risk of a heart attack, and large quantities of vitamin D have a long-term preventative effect on different cancer forms. The effect of these two different supplements is also affected by a person’s race.

Lack of vitamin D and selenium increases your risk of catching a cold or the flu or accompanying complications. Many people resort to Echinacea, ginger, and smoothies filled to the rim with vitamin C and secondary immune compounds, but these measures can never replace the two essential nutrients, selenium and vitamin D.

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.

- 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.

Atopic dermatitis is a common skin disease. Our modern lifestyle plays a role, and vitamin D deficiency in early childhood also seems to increase the risk of developing the disease later in life, according to a study that is published in World Allergy Organisation Journal. The health authorities recommend that pregnant women and small children take a vitamin Dsupplement.

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.

Inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis are becoming more and more common, even among young people. Diet, gut flora, and immune defense play a major role. Also, patients with inflammatory bowel disease seem to have lower blood levels of vitamin D, which is linked to the chronic inflammatory state and the progression of the disease. This was demonstrated in a study that was published recently in the science journal Medicine.

Insulin resistance is when the cells’ ability to take up glucose from the blood is impaired. It typically causes abnormal hunger and weight gain. Insulin resistance is also one of the symptoms of metabolic syndrome and type 2 diabetes. Previous studies have already demonstrated a link between vitamin D deficiency and the development of insulin resistance. The risk is even greater if you also lack magnesium, according to an American study. Here, the researchers look at interactions between vitamin D and magnesium and how this affects the blood sugar balance and health in general.

Irritable bowel is the most common intestinal disorder and affects around 15 percent of the population. The symptoms are typically unstable digestion, flatulence, constipation, diarrhea, stomach pain, and intestinal cramps. Several studies have shown that lack of vitamin D may cause the symptoms, and that taking a vitamin D supplement helps. This is because vitamin D is highly important for the intestinal immune defense and for controlling inflammation.

- and that is really bad for your health

Vitamin D comes in different forms that all need magnesium to be activated in order for the vitamin to be able to benefit all the cells and tissues in the body. Unfortunately, many people lack magnesium, and that makes vitamin D ineffective. Vitamin D also increases the uptake of calcium, but with too little magnesium in the organism, the risk of atherosclerosis increases, as does the risk of osteoporosis, impaired immune resistance, and metabolic syndrome (an early stage of type 2 diabetes.) All of this was observed in a study that is published in The Journal of the American Osteopathic Association.

Expecting mothers should pay careful attention to getting enough vitamin D all year round, especially because vitamin D deficiencies are so commonplace, to begin with. Lack of vitamin D at birth and the first years of life is associated with an increased risk of infant hypertension, and the problem can even continue to adulthood. This was shown in a study that is published in the science journal Hypertension. The researchers advise pregnant women to have their vitamin D levels measured, and they even recommend vitamin D supplements for pregnant women and children as a way of preventing elevated blood pressure later in life.

Scientists from Queensland in Australia have discovered that vitamin D is of vital importance to the structure and health of the brain. Also, deficiencies of the nutrient may lead to dysfunctions and loss of cognitive skills plus depression and schizophrenia. More than one billion people worldwide are believed to lack vitamin D. This may have widespread consequences for their health and may even be linked to the huge increase in mental illnesses.

The number of children and adolescents with ADHD has skyrocketed in the past decade, and the human and socioeconomic costs are enormous. A major cause may be the widespread problems with vitamin D deficiency, according to a study from Turku University in Finland. It does not make things any easier that sun awareness campaigns fail to give people an alternative way of getting enough vitamin D all year around, and it is also a problem that many pregnant women don’t take their supplements as recommended.

- especially among boys

Vitamin D controls a variety of processes in the brain and that is important for the child in a number of different ways. According to a new study from University of Queensland, Australia, there is an increased risk of autism – especially among boys – if the mother lacks vitamin D during her pregnancy. The explanation lies in the fact that the vitamin deficiency can affect levels of sex hormones in the brain. Several studies link vitamin D deficiency to autism and show that vitamin D supplements can improve hyperactivity and other signs of impaired functioning in children with autism.

- for longer periods

Vitamin D’s role in maintaining proper health is well documented. Still, many older people lack the nutrient and that increases their risk of bone fractures, blood poisoning, and disease complications that can eventually lead to hospitalization. Also, they risk prolonged hospitalization according to a new Irish study published in the scientific journal Nutrients. The scientists recommend giving vitamin D supplements to seniors to increase their blood levels of vitamin D. Other studies even suggest that this can protect against COVID-19, as low vitamin D status is associated with an increased risk of being hospitalized with the disease.

Vitamin D-deficient experimental animals are more likely to become dependent on opioids such as morphine, but their addiction decreases once their blood levels of vitamin D are restored. This was shown in an American study that is published in Science Advances. The scientists assume that low vitamin D levels also increase humans’ risk of growing dependent on opioids following medical pain treatment or other forms of exposure to addictive drugs. Both the legal and illegal opioid abuse in the United States is currently that extensive, experts refer to the problem as an epidemic. One potential way to deal with opioid dependence is to use vitamin D as a supplement, according to the researchers.

Atrial fibrillation is a rhythm disturbance in the electrical system of the heart. It is also one of the most common heart disorders and can be both harmless and potentially life-threatening. Lack of vitamin D increases the risk of normal atrial fibrillation and postoperative atrial fibrillation, according to a meta-analysis that is published in the scientific journal Nutrition. Vitamin D deficiencies are rather common so it is important to make sure to get enough of the nutrient for preventing and treating this disorder.

Vitamin D plays an overlooked role in the immune defense. Being deficient of the nutrient increases your risk of bacterial pneumonia by up to 60 percent, according to a large Danish study of 116,000 participants that was carried out by scientists from Herlev Hospital, Gentofte Hospital, and the University of Copenhagen.
Because many older people, cancer patients, and other chronically ill individuals are at increased risk of respiratory infections and because bacterial pneumonia can be potentially lethal, the scientists see a huge potential in using vitamin D supplements to prevent the disease.

- and worsens the odds for women who have the disease

Decades of research show that there is a link between lack of vitamin D and an increased risk of breast cancer. Vitamin D deficiencies are especially common at the northern latitudes because the sun sits too low in the sky for humans to be able to synthesize the vitamin during the winter. However, even in the southern hemisphere, many women have too little vitamin D because of spending too much time indoors, using too much suncream, or veiling themselves. Vitamin D has many anti-cancer properties, and postmenopausal women with too little vitamin D in their blood, who are diagnosed with breast cancer, have worse odds, according to a study of Brazilian women. In other words, it is not enough to treat breast cancer with surgery, chemotherapy, and radiation. You also need to optimize your blood levels of vitamin D and other nutrients, which the body needs in order to function optimally.

- and supplements save lives

Vitamin D deficiencies are widespread and result in an increased risk of atherosclerosis, heart disease, and hypertension, according to a new study from University of South Australia. Because cardiovascular diseases are the leading cause of death globally, scientists see a huge potential in vitamin D, a nutrient that may be able to save millions of lives.

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.

A large Irish study has shown for the first time ever that people from 50 years of age and older, who are vitamin D-deficient, are more likely to develop depression.
The study also showed that vitamin D deficiencies are more widespread among seniors, and that taking a vitamin D supplement can make a significant difference. The study supports earlier studies that also link vitamin D deficiency to an increased risk of depression, including winter depression. It is essential to get enough vitamin D all year round, as the nutrient is important for many different processes in the brain and even helps protect against local inflammation that is associated with depression.

It is hardly a coincidence that sore throats, colds, flus, and related complications such as sinus infections and pneumonia typically circulate during the winter period. They are primarily a result of having low vitamin Dlevels. During the winter, the sun sits too low in the sky to enable vitamin D synthesis in our skin, and we only have a limited amount of the nutrient stored in the liver. Good hand hygiene, warm soup, garlic, echinacea and other immune-boosting herbs alone will not deal with the problem, as they can never compensate for our lack of essential vitamin D, which the white blood cells of our immune system need in order to silently kill of virus. But how much vitamin D do we need, is it possible to get too much, and which mineral is necessary for activating the vitamin?

- a disabling and potentially life-threatening complication

Type 2 diabetes is currently treated with a number of different medical drugs. However, the medicine is not able to deal with the underlying causes of the disease that affects most organ systems. A Chinese study has demonstrated that vitamin Ddeficiency is linked to diabetic neuropathy, which is an insidious condition and is associated with inflammation, pain, amputation, circulatory failure, and early death.
It is important to get plenty of vitamin D at all times in order to prevent and treat the early phases of diabetic neuropathy.

PCOS or polycystic ovary syndrome is a hormone imbalance and the most common cause of involuntary female infertility. The disease brings on symptoms such as tiredness, sugar cravings, overweight, hirsutism, and an increased risk of type 2 diabetes. It turns out that women with PCOS also have lower levels of vitamin D in their blood and that can affect the development of the disease. Therefore, all women with PCOS should have their vitamin D levels checked and take supplements if necessary, according to a study from Saudi Arabia. In terms of PCOS prevention, it is also relevant to take a vitamin D supplement if you avoid the sun, wear full-body clothing, or live at northern latitudes.

Get lots of sunlight. It is the richest source of vitamin D. Also make sure to take a vitamin D supplement if, for some reason or other, you are unable to get enough sun exposure – and most certainly during the winter period. Studies show that lack of vitamin D may lead to heart failure due to insulin resistance, which is an early stage of diabetes. In other words, having too little vitamin D in your blood may impair the heart’s ability to take up blood sugar and that can cause a morbid enlargement of the cardiac muscle. This was seen in an Indian study that is published in the journal Molecular Nutrition and Food Research. The scientists see vitamin D as having huge potential in the prevention and treatment of cardiac failure plus insulin resistance and diabetes that is spreading like a bushfire.

The most common inflammatory bowel diseases are Crohn’s disease and ulcerative colitis. Lack of certain nutrients can contribute to the development of these conditions. On the other hand, the diseases and the therapies used to treat them may also impair the body’s ability to absorb or utilize certain nutrients, thereby starting a vicious cycle that can make the disease worse. This was demonstrated in a new Greek study that is published in Nutrients. Chronic inflammatory bowel diseases primarily occur in the Western countries and especially at northern latitudes, which suggests that sun exposure and typically Western diets pay a major role in the development of these diseases.

A large Israeli population study of over 4.6 million people shows that lack of sunshine and vitamin D increases the risk of COVID-19 infections and new infection waves in the winter period. The study shows why seniors, those with chronic disease, overweight individuals, and certain ethnic groups such as orthodox male Jews and female Muslims are more vulnerable. The scientists recommend vitamin D supplementation throughout the winter period or even all year round for those who do not get enough sun exposure during the summer. You can also read about why face masks block the body’s vitamin D synthesis, why COVID-19 originates from bats, and other mysteries related to the spread of the infection.

Girls with high blood levels of vitamin D are generally stronger, while the same relation is not seen in boys, according to a cohort study from Odense University Hospital in Denmark. The study is published in the Journal of Clinical Endocrinology and Metabolism. Nonetheless, all humans need adequate levels of vitamin D, as the nutrient has a number of other important functions in the body.

Menopause is characterized by a host of completely natural physiological changes in the hormonal balance. However, many women experience hormonal imbalances that may lead to weight gain, redistribution of their fat mass, increased abdominal obesity and an elevated risk of osteoporosis, cardiovascular disease, type 2 diabetes, and cancer. The hormonal changes may also affect the nutritional status including nutrients like vitamin D and magnesium, both of which are essential for prevention of the mentioned diseases. Now, scientists have discovered that lack of vitamin D and magnesium is widespread among menopausal women and that magnesium supplementation optimizes both levels of and the effect of vitamin D. This was demonstrated by a Spanish study that is published in Nutrients.

We need plenty of vitamin D for our bones and immune defense, for preventing cancer and so on, but if we lack magnesium, vitamin D does not work as expected. This is because magnesium is needed for activating vitamin D and enabling it to benefit the body’s cells and tissues. Magnesium also regulates blood levels of vitamin D, more specifically by increasing them if they are too low and lowering them if they are too high. This was demonstrated in a recent study from Vanderbilt University, the United States. The scientists call this highly important information, as there has been conflicting results from studies that compared blood levels of vitamin D in relation to colon cancer and various other diseases. Because magnesium deficiency is a widespread and overlooked problem, there is reason to believe that many people have difficulty with regulating levels of vitamin D in their blood. Also, they risk that their vitamin D does not have the desired effect in terms of preventing a host of different diseases.

Vitamin D deficiencies are very common. They increase children's risk of developing weak bones, but they also make adults more prone to osteoporosis.

Despite official recommendations to give infants a daily vitamin D supplement, nearly 50% of parents forget to follow this advice according to a large new Danish study. Not only do the children risk weak bones, it also increases their risk of infections and autism, other studies suggest.

During pregnancy, the unborn child is totally dependent on the mother’s vitamin D status. Vitamin D is primarily known for its role in supporting bone development. However, the vitamin is also of vital importance to the child’s brain, cognitive skills, and intelligence. According to a new, American study that is published in The Journal of Nutrition, this is why it is so important for pregnant women to have optimal vitamin D levels in their blood. The researchers point to the fact that vitamin D deficiencies are rather common and mention that they observed significantly lower blood levels of the nutrient in pregnant women of color. They hope their study can contribute to increased focus on the benefits of vitamin D supplementation in pregnancy.

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.

In the summertime, we synthesize vitamin D in our skin when we expose ourselves to sunlight. Vitamin D is a nutrient that is of vital importance to mood and health in general. When it is dark outside, we produce melatonin, which is important for our sleep. In addition to that, melatonin has a number of other important functions. Over the past decades, science has focused on its potential in the prevention of cancer, Alzheimer’s disease, sclerosis, and several other diseases. Apparently, vitamin D and melatonin work as hormones day and night and are of vital importance to the immune system. Also, they regulate inflammation, protect cells, and have many other functions. In a new review article that is published in Nutrients, the scientists refer to melatonin as the “next vitamin D”. Also, they mention that many people get too little sunlight during the day and too little darkness at night, which results in a deficiency of both vitamin D and melatonin.

Women in modern society typically live more than a third of their life after menopause. Once they stop menstruating, different hormone changes and ageing processes occur that can potentially affect health and quality of life. Studies show that certain B vitamins, vitamin C, vitamin D, and vitamin K2 affect our mood, cognitive functions, circulatory system, mucous membranes, connective tissues, bones, anti-cancer mechanisms and other functions. It is therefore important to get plenty of these nutrients, especially after menopause where women are particularly vulnerable.

Vitamin D is important for our bones, mood, immune defense, blood sugar levels, for regulating inflammation, prevention of cancer, and many other functions. Most attention has been focused on vitamin D’s role in preventing brittle bones rather than its ability to prevent all the other deficiency diseases that are linked to poor well-being, disease, and early death. Vitamin D deficiency is a global problem, and science has not yet come to an agreement with regard to how much vitamin D we humans need. However, according to a new meta-analysis that is published in Nutrients, daily supplementation with 50 micrograms of vitamin D appears to be an adequate and safe dose for most adults.

The winter period is the time of year where we typically lack vitamin D, and this contributes to new waves of COVID-19 and other virus infections. Moreover, many older people, dark-skinned individuals, nursing home residents, and diabetics often suffer from chronic vitamin D deficiency which makes them much more vulnerable. Since the springe of 2020, numerous studies have demonstrated that lack of vitamin D increases the risk of COVID-19 infections, acute respiratory distress syndrome (ARDS), intensive care admission, and death. This is described in a new meta-analysis that is published in Frontiers in Public Health. Danish threshold levels for vitamin D in the blood are also too low, apparently. The question is: How much vitamin D do we really need?

For decades, we’ve been told how dangerous the sun is and how important it is to protect ourselves. Now, a large British population study of more than half a million participants reveals that getting more sun exposure – even using tanning beds – is linked to fewer deaths from cardiovascular disease, cancer, and other things. The explanation lies in the UVB rays, which are the best way to get essential vitamin D, but only when the sun sits sufficiently high in the sky. It appears that all the sun awareness campaigns have done more harm than good, because it is vital to get enough sunlight, as long as we don’t get burned. The British study supports an earlier Swedish population study that revealed that lack of sun is every bit as harmful as smoking. People should take a vitamin D supplement during the winter period, and those who don’t get enough sun or who have difficulty with synthesizing vitamin D should supplement all year round.

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.

Diabetes is spreading with epidemic proportions, and an alarmingly high number of people are affected by metabolic syndrome, an early stage of diabetes that causes insulin resistance, elevated cholesterol, hypertension, and enlarged waist circumference. Ever since the 1970s, diabetics have been advised to stick with a low-fat diet consisting of bread, potatoes, and other carbohydrate sources. However, a new Danish study reveals that it is best to cut back on your carbohydrate intake. The new message to diabetics supports research from other parts of the world. Diabetics and people with sensitive blood sugar should focus on eating a diet with fewer carbohydrates, more protein, and more healthy fats. They should also make sure to get enough chromium, vitamin D, and magnesium, all of which are nutrients that support the body’s blood sugar levels. Furthermore, vitamin B12 and Q10 are important for those, who take diabetes medication and cholesterol-lowering drugs (statins).

Vitamin D controls a host of different biochemical processes that are of importance to our health. Moderate vitamin D deficiency is rather common, and severe deficiency is one of the reasons why chronically ill cancer patients are put in intensive care and die within a year. Cancer patients who have been in intensive care can actually benefit from takin vitamin D supplements, according to an Austrian study that is published in Nutrients. The study supports earlier research that demonstrates different anti-cancer mechanisms in vitamin D.

Vitamin D is vital for a well-functioning immune defense, yet a stunning 80 percent of patients hospitalized with COVID-19 lack the nutrient, according to a study published in The Journal of Clinical Endocrinology & Metabolism. Earlier research has shown that having too little vitamin D in your system increases the risk of life-threatening complications. It is also a well-known fact that vitamin D deficiency is a problem that is more widespread during the winter period, especially among exposed groups like seniors, nursing home residents, chronically ill, and dark-skinned people.
