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.

In a matter of four months only, large doses of vitamin D were able to reduce arterial stiffness in young, overweight but otherwise healthy Afro-Americans, according to a study from Georgia, the United States. The study also showed that those participants, who only took the officially recommended quantities of vitamin D, had increased arterial stiffness. This suggests that the official vitamin D recommendations are too low to prevent stiff arteries and atherosclerosis. Another thing is that dark-skinned people living at northern latitudes, overweight individuals, older people diabetics, and those who overuse sun screen are at increased risk of synthesizing too little vitamin D.

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.

Danish researchers have found a link between low levels of vitamin D in the blood and increased risk of early death. The alarming finding is published in the British Medical Journal.

American scientists have demonstrated that measurements of vitamin D levels in patients with early stages of sclerosis may predict how fast the disease will progress. If levels are low it may be a sign of faster disease progression and also a sign that this development may be slowed down if the patients increase their vitamin D intake.

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.

More than 25 percent of people older than 65 years have low levels of vitamin D in their blood. Deficiencies in vitamin B12, folic acid, and iron are also common. This is the conclusion of a large study that was conducted by scientists from Helmholtz Zentrum in Munich, Germany. The widespread lack of vitamins and minerals among older people is critical, especially because this population group is increasing. The lack of essential nutrients affects the calcium uptake, immune defense, and nervous system among other things, leaving older people increasingly vulnerable to osteoporosis, influenza, dementia, and a host of other diseases that impair quality of life and burden the entire public health sector.

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.

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?

Migraine is one of the most widespread neurological diseases, and it turns out that diet and lifestyle play a significant role. Supplementation with magnesium, vitamin D, Q10, vitamin B2, alpha-lipoic acid, and probiotics may relieve migraines or reduce the number of migraine days, according to a new meta-analysis published in Neurological Sciences. It is also essential to identify which nutrients the individual migraine patient lacks and aim at taking supplements that optimize blood levels of these substances.

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.

The carotid artery supplies the brain with blood, and narrowing can lead to debilitating and life-threatening strokes. According to a study on middle-aged participants with high blood pressure, a deficiency in vitamin D increases the risk of calcification and narrowing of the carotid artery.

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.

- and there is focus on nutrient deficiencies

The whole climate debate has made it increasingly popular to become a vegetarian or a vegan. However, according to a new and comprehensive study from Oxford, this choice of lifestyle may have grave health consequences and can increase your risk of apoplexy, also known as stroke, cerebral hemorrhage or cerebral thrombosis. The study is published in British Medical Journal. Earlier studies also give rise to concern, as a plant-based diet often lacks protein, vitamin D, vitamin B12, iodine, selenium, iron, and omega-3 fatty acids, and that can increase the risk of thyroid disorders, neurological disorders, infections, chronic inflammation, impaired fertility, growth disturbances in children etc. Some of these deficiencies are insidious and difficult to link to the diet.

- 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.

- and lacking responsibility contributes to the complicated COVID-19 infections

Health authorities worldwide recommend supplements of vitamin D to older people, nursing home residents, and people who get too little sun. However, most old people are not familiar with these recommendations, and vitamin D supplements are not handed out routinely in old age homes. Because of the widespread problems with vitamin D deficiency in these vulnerable groups, their risk of disease is increased. Also, they risk that a COVID-19 infection becomes complicated and life-threatening. A new British study set out to investigate the current practical guidelines for administering vitamin D supplements to nursing home residents and the responsibility for making sure this happens. The investigators believe that we desperately need a solution to this serious problem right now, considering the scope of the pandemic.

Strong bones require minerals such as calcium and magnesium. It is also known that vitamin D plays a role in calcium absorption, and deficiencies are common among the elderly. Furthermore, deficiencies in vitamin A, folic acid, and vitamin K appear to be much more widespread among elderly patients with bone fractures compared to healthy control groups. This is highlighted in a new study published in Frontiers in Nutrition, where the researchers take a closer look at the importance of vitamins for bone health.

Early stages of psychotic diseases such as schizophrenia are associated with deficiencies of specific nutrients like vitamin D and folic acid, according to a new Australian study. The researchers also point to new ways of preventing and treating psychotic disease, which affect millions of people worldwide.

Ovarian cancer is one of the deadliest cancer forms because it metastasizes in a very special way. It appears, however, that vitamin D is able to counteract one of the mechanisms through which this cancer spreads, according to a new Japanese study that is published in Matrix Biology. It is a problem that vitamin D deficiencies are so common because the vitamin supports several anti-cancer mechanisms.

Vitamin D is important for multiple metabolic processes. However, overweight individuals have difficulty with activating the form of vitamin D that we get from supplements, and that impairs their utilization of the nutrient. Therefore, vitamin D supplements work differently on those who take them to prevent diseases like cancer, diabetes, and autoimmune diseases, according to a large American study called VITAL. A group of scientists looked closer at the study and found that overweight people may have an increased need for vitamin D.

Vitamin D is important for our bones, cardiovascular system, immune defense, and for preventing cancer. Still, vitamin D supplements are less effective if you are overweight and that may lead to a variety of problems, according to a new study that is published in Journal of Bone and Mineral Research. In other words, being overweight means that you have an increased need for vitamin D. Other studies even show that overweight individuals have an increased need for magnesium, which activates vitamin D in the liver and kidneys with help from different enzymes.

- even in the case of COVID-19

Vitamin D is important for a well-functioning immune defense and a number of other functions. A team of scientists from Purdue University and National Institutes of Health in the United States has recently uncovered mechanisms that enable vitamin D to reduce hyperinflammation in severe COVID-19 cases. The scientists refer to a particularly active vitamin D metabolite that is formed in immune cells, in the lungs, and various other places. It is important to have adequate levels of vitamin D at all times, and it is equally vital for the body to be able to activate vitamin D, a process that requires the presence of magnesium.

Vitamin D protects against infections, cancer, and many different diseases, but there is a widespread deficiency problem. Also, the official recommendations for vitamin D intake are very low and are no guarantee of having optimal blood levels of the nutrient. A new British study that is published in Clinical Nutrition sheds light on the problems involved with helping an entire population to reach optimal vitamin D status. Apparently, there is no one-size-fits-all because age, gender, skin color, BMI, diabetes, and other factors can affect our ability to synthesize vitamin D and utilize the nutrient.

Phosphorous was discovered in the 1600s by an alchemist, who manage to make it from large quantities of urine. Ever since, phosphorous and similar compounds have been used to make matches, fireworks, nerve gas, bombs, manure, and pesticides. We hardly ever read or hear about phosphorous and its role in human health, but it is actually one of the most vital minerals, and it is important that we make sure to balance our levels of this mineral with calcium.

Impaired fertility and involuntary childlessness are common in the Nordic countries and there can be a number of reasons for these serious problems. However, according to a large Finnish study that is published in Nutrients, vitamin Ddeficiency, which is a widespread problem, may increase women’s risk of fertility problems and cause them to have a miscarriage.

Ageing is a complex process that increases your risk of chronic disease. Also, menopause is linked to an increased risk of metabolic syndrome, osteoporosis, and cardiovascular disease. Diet and lifestyle play a key role, and according to a review article published in Nutrients, combined therapy with vitamin D and K2 has a significant and positive effect on bone health, the heart, and the cardiovascular system in postmenopausal women.

Yet another example of how vitamin D affects more than strong bones. A study has shown that babies whose mothers took vitamin D during pregnancy had a stronger hand grip and greater muscle mass. This improved muscle strength may also be able to improve their health later in life.

It is important for the health of the unborn child that the expecting mother keeps her vitamin D levels high during her entire pregnancy. According to a study from Southampton University, vitamin D supplementation is less effective, if a pregnant woman starts with low levels of vitamin D in the early stage of her pregnancy, has major and sudden weight gain, and gives birth during winter.

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.

One in nine Danish women gets breast cancer, and the situation is not improving, on the contrary. One of the reasons why breast cancer is so widespread is that so many women lack vitamin D, and it looks as if the official recommendations for this nutrient are too low. A new American study has shown that those with higher amounts of vitamin D in the blood have a lower risk of the dreaded disease. The question is how much vitamin D do we need for optimal disease prevention, and what role does the nutrient play for those who have already been diagnosed with breast cancer?

Vitamin D is important for our bones, immune defense, muscles, hormone balance, blood sugar levels, nervous system, and for preventing cancer. According to a Polish study of elderly people hospitalized in geriatric wards, lack of vitamin D may trigger a host of different diseases and possibly be a useful marker of comorbidities and length of hospital stay. This study is highly relevant as the widespread problems with vitamin D deficiency have serious health-related and socioeconomic consequences, which could otherwise be avoided conveniently and at low cost with supplementation.

Psoriasis patients are generally interested in their diet and how it affects their disease. So far, there has not been much data so far to support a connection, but a new American study has mapped out the exact effects of regular diet habits and various supplements.

Red hair is thought to be a natural part of human evolution in the northern regions, where there is less sunshine. According to a Czech study that is published in Experimental Dermatology, redheads produce more vitamin D than people with other hair colors. Also, redhaired women live longer than women with other hair colors, according to a Swedish study that is published in PLoS One.

More and more people boost their immune with help from Echinacea, ginger, smoothies, and juices packed with vitamin C, antioxidants and secondary immune-strengthening compounds. Nonetheless, none of these otherwise useful strategies can compensate for the widespread lack of vitamin D that is the underlying reason why so many of us contract virus infections during the winter period.

An only six-month-old baby died of heart failure and the following complications. The tragedy was a result of severe vitamin D deficiency, which, according to researchers at the University of Birmingham, could have been avoided with better control. They now demand that the health authorities change their policy regarding vitamin D supplements, so that they take into account the special needs of babies, pregnant women, dark-skinned individuals, and population groups that are more likely to be vitamin D-deficient. With this tragic death, which does not stand alone, we are only seeing the tip of the iceberg. Having too little vitamin D can also increase your risk of weak bones, infections, asthma, autism, and many other diseases.

Vitamin D deficiency is a common problem among patients with rheumatoid arthritis. However, if their blood levels of vitamin D are high before they start on methotrexate therapy, it lowers their mortality. This was shown in a study published in Nutrients, where the authors looked at vitamin D’s therapeutic properties. Note that the official vitamin D recommendations are too low to optimize blood levels of the nutrient.

A growing number of children and teenagers suffer from anxiety, depression, and behavioral problems. Although there may be a number of underlying causes, it appears that vitamin D deficiency may be a contributing factor, according to a study that is published in the Journal of Nutrition. The problem is only made worse by the fact that many youngsters get too little sunlight during the summer period and that sun awareness campaigns warn against sun exposure without informing people about alternative ways of getting vitamin D. Vitamin D is important for bones but also for the brain, the nervous system, the immune defense, and many other physiological processes.

The condition of our skin means a lot to our appearance and health, and being deficient in one or several nutrients can cause premature skin ageing. Also, things like poor wound healing, acne, herpes infections, yeast infections, eczema, psoriasis, and other skin disorders may occur. In a review article published in Medicina, scientists have looked at the role of vitamins A, C, E, D, and biotin plus omega-3 fatty acids in skin health. Studies suggest that selenium and zinc may also be important for healthy skin and anti-ageing. If you don’t get enough of these nutrients or if you simply have an increased need for them, you may consider taking a supplement.

Vitamin D is important for the hormone system and our sleep, but certain environmental toxins like phthalates, bisphenol A, and triclosan can disrupt our hormone balance and sleep quality. Lack of vitamin D can even exacerbate the harmful effect of the hormone disruptors and, according to a study published in Nutrients, this may have a negative impact on our sleep.

A substantial number of people suffer from Hashimoto’s disease, a condition that causes hypothyroidism (slow metabolism), extreme fatigue, cold sensitivity, weight gain, and numerous other symptoms because the cells lack energy. Quite a few people suffering from this disease receive treatment, but the results are often unsatisfactory, and most people have not been given the correct diagnosis or do not receive proper help.

The low spring sun and bright sunlight can trigger a migraine attack. According to a new report, migraines may also be caused by a lack of vitamin D, which are common during the spring period. The combination of both is therefore rather unfortunate. Earlier and more recent studies show that lack of Q10, magnesium, and B vitamins can also trigger migraines, a condition that makes life miserable for millions of people. What is important is to detect and avoid the things that seem to cause these attacks and, at the same time, make sure to compensate for the nutrients, which the cells are lacking, in order to help the nervous system, the hormone system, and the cardiovascular system function properly.

In 2012 a Danish study was published in order to determine a possible correlation between, among others blood levels of vitamin D and deaths from all causes. This study has unnecessarily scared some from taking supplements of vitamin D, despite the fact that it showed that more than half of the participants suffered from vitamin D deficiency, and that only a minority had a very high vitamin D level, which not necessarily is the course of increased mortality.

It is common knowledge that too much sun exposure can cause skin cancer. On the other hand, lack of sunlight is also a problem. If you expose yourself to plenty of sunlight during your childhood years it lowers your risk of developing multiple sclerosis later in life, according to a study from University of California and Australian National University. The reason why sunlight protects against multiple sclerosis and a number of other illnesses is that the sun is our most important source of vitamin D a nutrient with multiple functions in the body. Therefore, it is essential to get plenty of sun as long as you avoid getting a sunburn. For people living at northern latitudes, it’s important to follow the official guidelines for vitamin D supplementation to make sure that we have enough vitamin D in our body at all times.

Several studies have shown a direct link between depression and lack of vitamin D, both of which are common problems. Vitamin D has numerous functions in the brain and nervous system and it helps counteract local inflammation that is often seen in connection with depression. According to a new Finish meta-analysis, high-dosed vitamin D supplementation can even ameliorate symptoms of depression. The question is how to optimize blood levels of the nutrient in order to prevent the disease.

- and you also need magnesium for your bones

It has been discussed whether it is calcium or vitamin D that improves women’s cholesterol balance. Earlier studies of women who use combined supplements have not been able to determine whether the positive effect is due to calcium or vitamin D. However, a study from Women’s Health Initiative (WHI) reveals that the effect is down to vitamin D. If you want strong bones and a healthy cardiovascular system, it is a good idea to combine both calcium and vitamin D with magnesium.

Autoimmune diseases occur in the wake of chronic inflammation and are the result of the immune defense erroneously attacking the body’s own tissues. Rheumatoid arthritis, psoriasis, sclerosis, and Hashimoto’s disease (that causes hypothyroidism) are all examples of autoimmune diseases that primarily affect women and older people. The diet plays a significant role and according to a study published in The British Medical Journal, supplements of vitamin D and fish oil taken for extended periods can lower the rate of autoimmune diseases. This is useful knowledge because these diseases are on the rise and the medicine that is used to treat them often comes with serious side effects.

Menstrual pain can be quite severe, especially among teenagers and young women, but supplementation with vitamin Dseems to reduce the pain, according to a new meta-analysis that is published in Nutrients. Earlier research has shown that fish oil supplements can do the same. Vitamin D and fish oil primarily work by lowering levels of hormone-like compounds called prostaglandins that cause inflammation and are responsible for the painful cramps in the uterus.

A recently published study shows promising results of giving daily supplements of vitamin D to sufferers of Crohn's disease. Apparently, the vitamin improves the intestinal barrier dysfunction associated with the ailment.

There is worldwide focus on finding better ways to prevent and treat COVID-19 because of the limited effect of vaccines. It is important to understand why the infections are harmless in most cases and why only a small number of people are affected by ARDS (acute respiratory distress syndrome), which is complicated and involves hyperinflammation. What represents the real problem here and what makes these infections life-threatening is a derailed and overactive immune defense. Multiple studies have already demonstrated that lack of vitamin D increases the risk of being infected with COVID-19 ending up in intensive care, and the studies also show that vitamin D supplements have a therapeutic potential. In a new review article that is published in Clinical and Molecular Allergy, researchers look closer at the synergy between vitamin D, magnesium, and zinc in relation to their ability to regulate the immune system and as potential therapeutic agents. It is also vital to have enough selenium, a nutrient that many people lack.

More and more people experience despair and depression. There can be several underlying factors but according to a large German population study, lack of vitamin D increases the risk of depressive symptoms. The scientists explain how vitamin reduces local inflammation in the brain, which increases the risk of developing a depression. That is why it is so important to get plenty of vitamin D all year round because the nutrient affects our mood and energy level in a variety of ways.

Considerably fewer cases of melanoma are found among people who take vitamin D supplements regularly compared with those who don’t. This was demonstrated in a new Finnish study that is published in Melanoma Research. The study supports earlier research that shows that lack of vitamin D doubles your risk of dying of melanoma.

An abundance of international science links widespread vitamin D deficiency to impaired immune defense, a problem that has contributed to new COVID-19 waves and tends to make the infections life-threatening. The British government has therefore decided to give free vitamin D supplements to 2.2 million seniors, nursing home residents, chronically ill, and other vulnerable people to help combat COVID-19. The whole purpose of this is to slow down the epidemic and put an end to the numerous shutdowns of society, according to an article in the Daily Mail.

Patients with chronic kidney disease (CKD) have an increased risk of both vitamin D deficiency and developing depression. According to a population study published in Frontiers in Nutrition, maintaining optimal vitamin D levels in the blood may reduce the risk of severe depression in these patients.

A woman’s estrogen balance is of vital importance to her fertility, mucosa, mood, libido, bones, cancer preventions, and many other things. There are also many myths about estrogen, which is merely a common term for the three types of estrogen – estradiol, estrone, and estriol – that have widely different functions. Like progesterone, stress hormones, and testosterone, estrogen belongs to the group of steroid hormones, where one hormone is built from another with help from enzymes. These enzymes depend on various nutrients such as iodine, vitamin D, magnesium, and selenium. If we lack these nutrients it may increase our risk of hormone imbalances, hot flushes, dry mucosa, bladder problems, and breast cancer. You can also read more about hormone-disrupting substances, hormone therapy, and bioidentical hormones.

- from the first trimester

A pregnant woman's vitamin D level in the first trimester is relevant for the development and growth of the fetus. According to a study published in The American Journal of Clinical Nutrition, being vitamin D-deficient during the first trimester can increase the risk of preterm birth and decreased birth length.

There are countless reasons why an expecting mother must make sure to get plenty of vitamin D to support the health of her child. Neonates that lack vitamin D are 44% more likely to develop schizophrenia later in life compared with neonates that do not have a vitamin D deficiency. This was demonstrated by Danish and Australian researchers in a recent study. This vital knowledge may help prevent schizophrenia in the future, and the scientists therefore recommend more focus on the importance of having adequate vitamin D levels during pregnancy.

Vitamin D is important for cellular calcium uptake, bone health, and a number of other functions. There is also a direct link between the widespread vitamin D deficiency problem and brittle bones and osteoporosis among post-menopausal women, according to a large Chinese study that is published in Frontiers in Nutrition. It is important to include magnesium and vitamin K2, as they also contribute to bone health.

There is a link between low blood levels of vitamin Dand low levels of testosterone in overweight, young men, according to a study that is published in the scientific journal Frontiers in Endocrinology. It is also well known that vitamin D deficiency is more widespread among overweight people and this can affect your resistance, blood sugar levels, and a number of other functions. In fact, overweight individuals should make sure to get enough vitamin D. For men, it’s vital to produce sufficient quantities of testosterone, a hormone that is important for muscle mass, bones, vitality, fertility, and libido.

Vitamin D is of vital importance to the unborn child’s development of teeth, bones, immune defense, and various other things. The fetus is highly dependent on the mother’s vitamin D levels and that the nutrient can be transferred to the fetus and activated. A team of scientists has looked closer at the placenta and its role in helping the fetus utilize vitamin D. They hope their work can contribute to healthier pregnancies in the future.

Type 2 diabetes is spreading like a bushfire and is the major cause of vision loss, kidney failure, heart attacks, strokes, and leg amputations. Many people have insulin resistance, the early stage of type diabetes that is associated with fatigue, untimely hunger, and increasing weight. The diet plays a major role and according to a new review article that is published in Human Nutrition and Metabolism, various B vitamins, vitamin D, vitamin K, vitamin E, and zinc influence insulin resistance and diabetes treatment. Previous research has also shown that chromium and magnesium play a role in insulin resistance and blood sugar regulation.

We are constantly being warned about sun exposure and skin cancer. Still, it is important that we get plenty of vitamin D from sunshine - as long as we avoid getting burned. Vitamin D prevents and cures many diseases, and it may not only be the Mediterranean diet alone but the increased sun exposure and higher vitamin D levels that help people in Southern Europe avoid cardiovascular disease and other ailments.

It is mainly older people and those with chronic illnesses that are vulnerable to COVID-19 and other respiratory infections. Also, it’s a fact that lack of essential nutrients impairs your immune defense and may have serious health consequences, whether you are vaccinated or not. A large study of 19 European countries reveals that low blood levels of vitamin D increases the risk of complicated COVID-19 infections, hospitalization, and death. According to the scientists, it is necessary to discuss and optimize people’s vitamin D status to help them resist future pandemics.

Elevated blood pressure is one of the most widespread, life-threatening cardiovascular diseases. Anti-hypertensive drugs don’t address the underlying cause and are even associated with side effects. Lack of vitamin D, which can cause different cardiovascular diseases, is also quite common. According to a large Spanish population study, having higher levels of vitamin D in the blood can lower the risk of hypertension. In their research paper, the scientists address the mechanisms through which vitamin D is thought to control blood pressure.

A growing number of people suffer from overweight and type 2 diabetes, both of which are problems that come at a cost both to society and to the individual. The traditional dietary guidelines are not of much use, and many people find themselves in a hopeless battle because they also suffer from insulin resistance with impaired cellular glucose uptake. Countless epidemiological studies have demonstrated that the widespread lack of vitamin D contributes to the problem. In a review article that is published in Nutrients, the scientists address vitamin D’s many functions with relation to blood glucose regulation, satiety, body weight, and prevention of type 2 diabetes. It should be noted that overweight people and type 2 diabetics may have an increased need for vitamin D, and magnesium is also required for activating the vitamin.

Type 2 diabetes is spreading like a bushfire, and most people will be affected by periodontal disease at some point in their life. Now, science has discovered that lack of vitamin D, which is also increasingly common, enhances the risk of both diseases. Their observation is based on new study that sheds light, for the very first time, on vitamin D and its role in preventing and treating the two conditions.

During the winter period, many people catch a cold or are bed-ridden with a bout of the flu. They may consider this to be perfectly natural, but it is actually a sign of a weakened immune defense, and that makes them susceptible to contamination. What matters is to make sure to get plenty of vitamin D, vitamin C, selenium, and zinc, all of which are nutrients that have different functions in the immune system. Some nutrients are also needed in larger quantities to tackle a beginning infection, and it is important to act quickly in order to nip the infection in the bud.
In fact, it is vital for us to be nutritionally bolstered during the winter period, where otherwise harmless virus infections can lead to complications such as herpes, bronchitis, and pneumonia, if the immune system is unable to work full throttle.

Lack of vitamin D can impair your muscle function because it causes muscle cells to produce less energy, according to a study that is published in Journal of Endocrinology. The scientists use their study to argue that one can improve muscle function and reduce age-related loss of muscle strength in seniors by making sure they get enough vitamin D. If your muscles feel weaker during the winter period, you may want to consider taking a supplement.

Clostridium difficile is a bacterium that causes diarrhea and intestinal infection. The infection may even be life-threatening. A new American study that is published in PLoS Pathogens shows that this bacterium can only thrive with an overload of calcium in the intestinal system. Such a calcium excess can be caused by overconsumption of calcium, lack of vitamin D, and regular use of antacids.

- and people are misguided

Unhealthy eating habits account for one in five deaths globally and are now considered the single most life-threatening risk factor. In most countries, people could reap a lot of health benefits and live longer by eating healthier diets, but it would be wrong to hold each individual responsible because there is an urgent need for international collaboration that involves politicians, agriculture, the food industry, and the health sector, according to a new study (The Global Burden of Disease) that is published in The Lancet. An earlier and larger Czech study published in the science journal Nutrients calls for a paradigm shift with regard to diet recommendations, claiming that the scaremongering about saturated fat and cholesterol should never have been introduced.

Sun awareness campaigns have scared people away from sun exposure because of the risk of skin cancer. Still, it is essential to get enough vitamin D from the sun during the summer period, as long as we avoid getting sunburned. Vitamin D is vital for our immune defense, mood, bone health, cancer prevention, and many other things. A Swedish study has revealed that lack of sunshine is every bit as dangerous as smoking, and according to a British study, vitamin D inhibits cellular ageing. A Danish study has even shown that lack of vitamin D increases the risk of early death. The big questions are how much vitamin D do we get from sun exposure during the summer period, when do we need to take vitamin D supplements, and why should old people, dark-skinned individuals, and certain other population groups take vitamin D all year round?

– and that may harm your fertility, metabolism, nervous system, and the growth of your child

Everyone is talking about the climate, and meat has lost popularity for a number of reasons. But let us keep our heads clear on the facts. There is a big difference between CO2 emissions, animal welfare, and the quality or quantity of meat on one hand and the nutritional aspects of meat on the other hand. Humans have been eating meat (including fish) for around two million years, and animal food sources have contributed to our large brains and development in general. Nonetheless, more and more people choose to become vegetarians, and the trend is especially popular among women. This gives rise for concern, as lack of protein, vitamin D, vitamin B12, iodine, selenium, iron, zinc and omega-3 fatty acids not only impairs fertility but even increases the risk of metabolic disorders, serious growth disturbances in children and a lot more. Some of these symptoms are insidious and therefore difficult to link to the diet.

If you are vegetarian or vegan you need keen insight in order to know how to get enough protein, vitamins, minerals, fatty acids, and certain amino acids. Lack of essential nutrients can cause anemia and fatigue but may also increase your risk of serious diseases.

Neurologists agree that the brain’s neurons constantly change in relation to stimuli from the inside and outside environment. That is how we learn new skills and develop our memory. The brain’s ability to adapt and change is called neuroplasticity and doctors have suspected for a long time that it takes place in the synapses. A team of scientists from the University of Freiburg in Germany has discovered that a vitamin A-like compound affects the neurons and their ability to adapt to structure and function. The scientists hope that their discovery can contribute to the development of new therapies for treating brain disorders. Earlier studies have shown that omega-3 fatty acids, vitamin D, and lifestyle in general also affect the brain’s neuroplasticity and development.

According to a large American study, a high dietary intake of vitamin D and calcium is associated with a lower risk of early-onset menopause, where the menstrual periods cease before a woman reaches 45 years of age. Premature menopause affects around 10 percent of women, and the condition increases the risk of impaired fertility, osteoporosis, cardiovascular disease, and earlier cognitive impairment. The prevention of these diseases is also a matter of getting enough sunshine, magnesium, and omega-3.

More vitamin D may contribute to better blood sugar regulation in type 2 diabetes. Eggs are a good source of vitamin D, but in the winter period it may be a good idea to take a high-dosed supplement.

Babies and small children are less likely to develop croup if their mothers have taken high-dosed vitamin D and fish oil during their pregnancy, according to a Danish study, where scientists have studied this relation for the very first time. Vitamin D and fish oil also benefit the child’s immune defense and counteract the inflammation in the respiratory system that triggers croup. The two supplements even have a positive impact on the child’s bone health and nervous system, and they also help prevent asthma.

Lack of vitamin D is rather common and is associated with a host of diseases that affect the teeth and gums. In children, a vitamin D deficiency may result in fragile teeth with weak enamel and an increased risk of cavities. Later in life, the vitamin deficiency may also increase the risk of periodontal disease and certain types of oral cancer, according to an article that is published in the scientific journal Nutrients. The authors refer to a number of clinical studies that point to vitamin D’s different functions with regard to dental health. Also, they mention that vitamin D deficiencies are widespread and write that it may be necessary to take a supplement for proper dental health.

Low blood levels of vitamin D are associated with an increased risk of breast cancer. Also, breast cancer patients with optimal levels of vitamin D in their blood can expect to live longer than breast cancer patients with low blood levels of the nutrient. But how much vitamin D is needed to prevent the dreaded disease?

Researchers have found that individuals who are genetically prone to low vitamin D status have an increased risk of multiple sclerosis.

A team of researchers from McGill University, Canada, has found a link between decreased vitamin D status and increased risk of multiple sclerosis (MS). In their study, which is published in PLOS Medicine, they compared data from thousands of participants with and without MS. As part of their research they looked at how genetic factors affected vitamin D levels in the participants. The researchers found that those people who were genetically prone to low vitamin D status were at least twice as likely to have MS. To explain their observations in more simple terms, when you increase a person's circulating levels of 25OHD (biologically active vitamin D) by 1.5-fold, it decreases their risk of developing MS by 50%.

Recent studies reveal that vitamin D and omega-3 fatty acids are able to prevent and ameliorate a number of neurological ailments such as depression, ADHD, bipolar disorder, autism, and schizophrenia. There is evidence suggesting that vitamin D and omega-3 fatty acids work by controlling the synthesis of serotonin in the brain. The listed neurological conditions are all characterized by defects in the body’s synthesis of this important neurotransmitter. It is therefore vital to get plenty of sunshine, vitamin D, and omega-3 fatty acids, as widespread deficiencies in all three most likely contribute to the increasing rate of different neurological disorders.

There is a link between the widespread problems with vitamin D deficiency and the growing prevalence of Parkinson’s disease. In a review article that is published in the science journal Nutrients, a group of scientists look at vitamin D’s role in the nervous system and the brain. It is relevant to use supplements that optimize blood levels of vitamin D as part of the prevention and treatment of this disease.

Schizophrenia is known to impair quality of life and reduce life expectancy. Diet, lack of nutrients, and digestion are all important for the progression of the disease, according to an Iranian study of schizophrenics who were given supplements of vitamin D plus lactic acid bacteria and bifidobacteria. The study is published in Neuropsychopharmacology Reports and reveals that these supplements were able to significantly improve the cognitive skills of the patients. The researchers also mention that these supplements have a role in regulating the body’s production of dopamine, controlling inflammatory processes, and controlling the gut-brain-axis that is important for the communication between the gut and the brain.

Vitamin D is essential for the immune defense but many of us are deficient of the nutrient during the dark winter period. The Danish Veterinary and Food Administration therefore recommends for everyone to take a vitamin D supplement in the winter months and that vulnerable population groups supplement all year round. Many people are unaware that being vitamin D-deficient contributes to new waves of COVID-19 and other types of viruses while increasing the risk of infections becoming complicated and life-threatening. This was demonstrated in multiple studies that have been published over the past 18 months. Leading scientists call for immediate action in terms of optimizing vitamin D levels in the population to help fight COVID-19 and other virus infections, simply because vaccines only have limited effect.

All cells in the body depend on vitamin D. Unfortunately, many people lack the nutrient, and the list of diseases caused by too little vitamin D is growing. A new study from Trinity College in Dublin shows that it is possible to measure vitamin D levels in hair, and this can reveal the large fluctuations that occur in the course of a year, and which an ordinary blood test fails to show. The scientists can see a huge potential with this new type of measurement, which can even be used on historical populations such as the ancient Egyptians or on prehistoric animals such as the mammoths.

Danish scientists from Aalborg University have published a study of mice in which they demonstrate that vitamin D prevents cancer by affecting a particular kind of gut bacteria. A subsequent analysis of 1.5 million Danes shows a similar relation between low vitamin D levels in the blood and an increased risk of several cancer types. What is also worth mentioning is that the official vitamin D recommendations appear to be too low to be able optimize blood levels of the nutrient.

Women who get sufficient vitamin D is approximately one-third less likely to develop fibroids in the wall of the uterus, according to a U.S. study published in the journal Epidemiology. This study is the first to relate uterine fibroids to the level of vitamin D.

Vitamin D is essential for the immune defense. Because deficiencies of the nutrient are becoming increasingly common and vaccines only have limited effect, we can expect new waves of COVID-19 during the winter period. Vitamin D counteracts chronic inflammation which is seen in rheumatoid arthritis, diabetes, and other chronic diseases. Multiple studies have shown a link between low blood levels of vitamin D and the occurrence of these diseases. In a new meta-analysis that is published in Molecular and Cellular Biochemistry, scientists look closer at the scientific data for risk factors involved with vitamin D deficiencies and the advantages of taking vitamin D supplements in connection with COVID-19, rheumatoid arthritis, and other inflammatory diseases.

Metabolic syndrome, which is the early stage of type 2 diabetes, is associated with overweight, insulin resistance, hypertension, and other metabolic disturbances. Low blood levels of vitamin D also appear to significantly increase the risk of metabolic syndrome, according to a large population study of young and middle-aged Chinese people. The researchers mention that vitamin D is important for blood sugar levels, lipid metabolism, and weight regulation. It is worth making a note of the fact that official guidelines for vitamin D supplementation are no guarantee of optimal blood levels of the nutrient.

Patients admitted to the intensive care unit often lack vitamin D, resulting in more complications, prolonged ICU stay, and increased mortality compared with patients who have adequate vitamin D levels in their blood. This was demonstrated in an Iranian study from three hospitals. The study is published in BMJ Nutrition. Many older people and individuals with chronic diseases generally lack vitamin D, which is a problem.

Dementia is on the rise across the globe but according to a study from University of South Australia, vitamin D may have the potential to pull the brake on the degenerative processes. The scientists have observed a direct link between the widespread problems with vitamin D deficiency and the increasing rate of dementia. At the same time, they assume that optimizing people’s vitamin D status in the blood may help prevent millions of dementia cases worldwide. The need for vitamin D varies from person to person, it should be noted, and many people have a higher need for the vitamin than what is officially recommended.

According to WHO, the number of overweight children has reached epidemic proportions. Overweight children risk being overweight as adults and develop hypertension, cardiovascular disease, type 2 diabetes, chronic inflammation, and other metabolic disturbances. Apparently, overweight individuals often lack vitamin D, a nutrient that is important for regulating weight, inflammation, and many metabolic processes. This was pointed out in an Italian study published in Nutrients, where the authors address vitamin D’s role in health and explain why so many overweight people are vitamin D-deficient.

The body’s vitamin D status can be used to predict the risk of contracting COVID-19, developing serious symptoms in the acute disease phase, and dying of its complications. This was demonstrated in a large Chinese study, where majmost of the hospitalized COVID-19 patients lacked vitamin D.

- especially babies of color

Vitamin D is vital for normal development of the baby’s bones, cognitive skills, IQ, immune defense, and a number of other things. According to a new British study, however, a third of white infants lack vitamin D. The problem is even more pronounced in dark-skinned babies. Here, around half of them lack vitamin D. More focus is needed on pregnant women from exposed groups to help ensure that they get adequate amounts of the nutrient.

Vitamin D deficiencies are widespread among people who are overweight or have type-2 diabetes. However, researchers have not been able to explain the exact link. A study done by researchers from Baylor College of Medicine, Houston, Texas, suggests that it has something to do with vitamin D’s role in the brain, where the nutrient helps control both weight and blood sugar levels.
