- 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.
Vitamin C is essential for the immune defense for a number of reasons. According to a review of 12 recent studies, vitamin C administered in sufficiently high doses can prevent severe COVID-19 infections and save lives. The problem is that most people fail to follow the official dietary guidelines for fruit and vegetable consumption, which is why so many people lack vitamin C. Another thing is that health authorities in general are unaware of the health benefits of vitamin C in therapeutic doses, even after 80 years of international research.
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.
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 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?
If you lose your sense of smell all of a sudden, it is most likely a sign that you have been infected with the coronavirus, according two large, international studies published in the science journal Chemical Senses. Many COVID-19 patients also lose their sense of taste and even if there are no other complications, it can affect their quality of life. The big question is if there is a link between zinc deficiency, corona infection, and these symptoms. It is already an established fact that zinc is important for our immune defense, for our sense of taste and smell, and as an antioxidant that protects our cells. Also, it is known that zinc deficiencies are rather common and people with unhealthy eating habits, vegetarians, vegans, older people, and diabetics are at increased risk. Birth control pills and certain types of medicine also increase the risk of lacking zinc.
- 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.
According to a pilot study from Los Angeles, patients with higher blood levels of omega-3fatty acids in their blood are 75 percent less likely to die from a COVID-19 infection. The scientists behind the study assume it is because of the anti-inflammatory properties of the omega-3 fatty acids and their ability to regulate the immune defense, which is often completely derailed in serious cases of COVID-19. The scientists also mention other nutrients with anti-inflammatory properties.
Magnesium is involved in hundreds of chemical reactions in the body, including the activation of vitamin D that we synthesize from sun exposure or take in supplement form. For that reason, magnesium is essential for the immune defense and its ability to fight COVID-19. Moreover, low magnesium levels in the body can foreshadow complications in connection with a COVID-19 infection, according to a study that is published in Nutrients. The scientists therefore say that it is relevant to measure hospitalized patients’ magnesium levels and correct any deficiencies. Many people, especially older individuals, get too little magnesium from their diets, and several types of medicine can impair the uptake and utilization of the nutrient.
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.
The COVID-19 pandemic is continuing and we are currently being threatened by B117 and other mutated versions of the virus. Some people are immune, some get mild infections, and some develop life-threatening complications. A team of international scientists has tried to find out why people react so differently. It appears vitamin D deficiency plays a major role. According to a new study that is published in the science journal Endocrine in January 2021, low blood levels of vitamin D are linked to an increased risk of being hospitalized. The scientists behind the new study point to vitamin D supplements as an inexpensive and fast way to improve patients’ health.
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?
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.
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.
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.
HIV, the virus that causes AIDS, is potentially life-threatening because it attacks central cells in the immune defense. It has also been documented that HIV patients have an increased risk of lacking vitamin D. This can be because of the disease itself, the combination therapy, lack of sun exposure, or other factors. Vitamin D is important for the immune defense, the bones, our mood, and numerous other functions. According to a new article published in MedicalNews Today, it is important to measure HIV patients’ blood levels of vitamin D and possibly give them high-dosed supplements to optimize levels of the nutrient. Earlier studies point to a link between the course of an HIV infections and the body’s selenium status.
Chronic fatigue commonly follows in the wake of influenza, herpes, COVID-19, and other infections. The immune system does not function optimally, and the tiredness is caused by oxidative stress and inflammation. The condition is often accompanied by poor concentration, depression, and sleep disturbances. Oxidative stress is an imbalance between pro-inflammatory free radicals and protective antioxidants. Vitamin Chappens to be one of the most potent antioxidants, and intravenous vitamin C therapy has been shown to reduce tiredness that follows after different types of virus infections, according to a review article in the scientific journal Nutrients. Here, the scientists also write about intravenous vitamin C therapy in connection with chronic fatigue syndrome following COVID-19 infections.
Vitamin B6 is important for our energy levels, immune defense, nervous system, and a host of other functions. Vitamin B6 may even be able to reduce the severity of COVID-19 infections, according to an article written by Japanese, Chinese, and Thai scientists and published in Frontiers in Nutrition. The researchers refer to several clinical studies that show how vitamin C, vitamin D, magnesium, and zinc are able to reduce serious symptoms in COVID-19 patients, and they call for more studies of vitamin B6, simply because patients that are severely affected by COVID-19 often suffer from traumatic diseases and lack of several essential nutrients.
When it comes to COVID-19 and other seasonal virus infections most of the focus is concentrated on vitamin D deficiency. According to a Belgian study, however, lack of selenium and zinc additionally increases the risk of infections, complications, and death, especially among patients who already suffer from chronic diseases. The scientists conclude that supplementation with selenium and zinc may help improve treatments. Selenium and zinc deficiencies are rather common and that is a problem for public health. Even with a healthy diet, it is practically impossible for Europeans to get enough selenium because of the nutrient-depleted farmland. There are also many people with zinc deficiencies due to unhealthy diets, ageing, chronic diseases, and other contributing factors. We must be much more focused on getting enough selenium and zinc, not least for the sake of preventing virus infections and other problems.
- and become increasingly dangerous
Around one billion people worldwide are believed to lack selenium, mainly due to nutrient-depleted farmland. Selenium deficiency makes us more vulnerable to infections and increases the risk of a virus mutating and becoming more dangerous. This was shown in previous studies of RNA virus that can cause influenza, hepatitis, HIV, and Keshan disease. Coronavirus that causes the common cold and COVID-19 infections also belongs to the group of RNA virus and has a unique ability to mutate. Three new mutated virus types have been found in mink and stand in the way of a future vaccine. Therefore, we are forced to bolster our immune defense, which is designed to attack virus from different angles. Still, even if we eat a healthy diet it can be challenging to get enough selenium, and that is why an increasing number of international researchers now recommend selenium supplements to help fight coronavirus.
– and could even make them more dangerous
Selenium is of vital importance to a strong immune defense. Still, selenium deficiency is a common problem and it increases the risk of viral infections such as influenza and the coronavirus from China, which is feared to turn into a global pandemic. It is a problem that selenium deficiency in infected animals and humans causes the virus to mutate and become more aggressive. Because of selenium’s important role as a powerful antioxidant, being deficient of this micronutrient may leave the body vulnerable to oxidative stress, which can cause tissue damage and complicate the virus infection. It is therefore important to get enough selenium at all times, as it also increases our resistance towards other viral infections such as herpes, HIV, and hepatitis, according to an article published in Nutrients.
Vitamin C has a vital role in our immune defense, and having low blood levels of the nutrient can affect the severity of infections such as COVID-19 and influenza, according to a review article published in Aging and Disease. The scientists behind the study also refer to other studies that have looked at large doses of intravenous vitamin C given to patients with sepsis and life-threatening COVID-19 infections. Vitamin C deficiency is a widespread problem for various reasons and that only adds to the problem.
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 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.
An international science team from the University of Surrey in England has found a link between low selenium levels in the soil and the risk od COVID-19 infections becoming lethal. Professor Margaret Rayman, who headed the study, has spent decades studying the global lack of selenium that is known to impair the ability of the immune system to tackle virus infections and new epidemics. The farmlands in large parts of the world, including Europe and China, are low in selenium, and it is vital to have more focus on this essential nutrient.
Magnesium plays a vital role in the immune defense by regulating inflammation, which is a property that determines the body’s ability to tackle COVID-19 and other infections. People who lack magnesium have an increased risk of being infected with COVID-19 and also that the infection becomes life-threatening. This was shown in a large American population study that also revealed how widespread a problem magnesium deficiency is. The scientists therefore assume that an optimization of people’s magnesium status in the future can contribute to the protection against COVID-19 and similar respiratory infections. It is also important to get enough vitamin D because the two nutrients interact with each other.
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?
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.
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.
Australian scientists are about to initiate the first clinical trial of intravenous zinc therapy for COVID-19 patients. Zinc is important for our immune capacity but it also helps counteract organ damage caused by an impaired oxygen supply to the cells and hyperinflammation. Zinc deficiencies are common, especially among older people, chronically ill, and other exposed groups.
- 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.
- 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.
After a COVID-19 infection many people experience chronic symptoms such as fatigue, muscle pain, depression, and sleep disturbances. According to a study that is published in Clinical and Experimental Medicine, supplementing with Q10and alpha-lipoic acid may help against tiredness and certain other symptoms. The authors describe how Q10 and alpha-lipoic acid support the cellular energy turnover in different ways and serve as antioxidants that protect cells against oxidative stress and cellular damage.
The corona crisis has shed new light on the importance of having a strong immune defense, one that protects us against virus infections in the long run. Selenium plays a vital role for a number of different reasons but, unfortunately, there is widespread deficiency which increases the risk of infections and related complications. In a new review article that is published in International Journal of Molecular Sciences, the authors look closer at selenium’s role in connection with different types of virus infections such as influenza, HIV, and hepatitis with particular focus on COVID-19. The purpose of their article is to inform about new nutritional strategies that may contribute to a strong and well-functioning immune defense – mainly when it comes to COVID-19 and virus types that tend to mutate all the time.
Our nutritional status is of vital importance to our health and our ability to handle infections. Seleniumhas several functions in the immune system, including its role as an antioxidant and in counteracting unwanted inflammation. Selenium is also able to prevent virus from mutating and becoming more virulent or creating new waves of disease. A team of Chinese scientists have reviewed a number of studies of selenium and its key role in the defense against influenza, HIV, and other types of RNA virus. They have found, among other things, that the risk of contracting a COVID-19 infection is 10 times lower in areas where the soil is rich in selenium. Therefore, it is a huge problem that selenium deficiency due to selenium-depleted farmland is so widespread in Europe, China, Africa, and many other places.
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.
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.
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.
Vitamin D-deficient patients are twice as likely to sustain life-threatening complications in the wake of a COVID-19 infection, according to a study from Northwestern University in the United States, where scientists collected data from 10 different countries. It is worth making a note of the fact that vitamin D deficiencies are particularly common among older people of color, nursing home residents, overweight people, and chronically ill individuals, all of which are well-known risk groups. In the future fight against COVID-19 and other epidemics, good hygiene, hand sanitizer, isolation, and delayed vaccines are not enough. We must take the right measures to regulate our immune system with vitamin D, which can determine whether we reject the virus, contract a mild infection, or die of the subsequent, life-threatening cytokine storm and organ failure.
It is already known that severely affected corona patients often lack vitamin D and selenium, both of which are nutrients that are important for the immune system. A team of Danish scientists has now confirmed a Dutch study showing that lack of vitamin K is also widespread among patients with severe cases of the coronavirus. Vitamin K is mainly found in dark, leafy greens. In the body, the nutrient occurs as vitamin K1 and vitamin K2 and they have different functions. Lack of vitamin K or poor utilization of the nutrient may be a result of a poor diet or using certain types of medicine. Although there is no evidence that vitamin K can prevent or mitigate corona infections, the scientists present several interesting hypotheses.
The trace element selenium has a vital yet overlooked role in ensuring a well-functioning immune system, and the widespread problems with selenium deficiency increase the risk of dying of COVID-19, according to a large German study that is published in the science journal Nutrients. The scientists therefore conclude that determining the patients’ blood selenium levels may provide vital diagnostic information. Also, the researchers conclude that it may be necessary to include selenium supplements in the treatment of COVID-19, especially with older people, diabetics, and those with chronic diseases that are at particular risk of life-threatening complications. The agricultural soil in Europe and other parts of the world contains relatively little selenium, which is why it is imperative to focus more on getting adequate amounts of this essential nutrient for the sake of preventing COVID-19 and other viral infections. It appears that the official recommendations – the so-called reference intake levels or RI – are not sufficient to meet the body’s actual requirements.
