- atherosclerosis, and early death
Cholesterol is an essential compound with many different functions. However, it can also turn into a potentially dangerous substance if it oxidizes and is embedded in the blood vessel walls. This oxidative process is what eventually leads to atherosclerosis. The trace element selenium protects against atherosclerosis because of its antioxidant properties and because of other mechanisms, according to a review article published in Biomedicine. This is highly relevant in our part of the world where cardiovascular disease is the leading cause of death, and where seleniumdeficiency is so widespread.
Professor Maret Traber from the Linus Pauling Institute in the United States has studied vitamin E for a number of years. Traber, in a review article, looked at the most recent science concerning this important, lipid-soluble nutrient. Judging from her work, it looks as if we only need the form of vitamin E called alfa-tocopherol.
Alcohol has a greater negative impact on public health than most other things. It is commonly known that alcohol abuse burdens the liver and depletes the body of B vitamins. Now, scientists have also demonstrated that overconsumption of alcohol leaches vitamin Cfrom the body, and they call for further studies to show that vitamin C supplements may help improve the health of alcoholics. It is also possible that vitamin C supplementation can limit the damage of short-term excessive drinking. Their new review article is published in BMJ Nutrition, Prevention & Health.
Antioxidants such as vitamin C are able to counteract chromium-6 poisoning, according to a new study that is published in Experimental Biology. Chromium-6 (hexavalent chromium) is used for many industrial purposes, and the different signs of poisoning such as cancer were described in the movie “Erin Brockovich” that is based on a true story. Now, Danish scientists even claim that the threshold level for chromium-6 is far too high and gives a false sense of security. It is vital to avoid exposure to chromium-6 and to get plenty of protective antioxidants. However, we depend on chromium-3 (trivalent chromium) for controlling our blood sugar levels.
Yes, according to a new study published in Free Radical Biology & Medicine, lack of seleniumlowers the kidneys’ sodium excretion via different mechanisms, and that leads to elevated blood pressure. The study results are highly relevant because hypertension and subsequent premature death is a growing global problem. Selenium deficiency is also a widespread problem. One billion people worldwide are believed to be lack this essential nutrient, primarily because of the selenium-depleted agricultural soil in large parts of China, Europe, and other places.
COVID-19 represents a serious global threat against public health and the economy because we still lack a vaccine and effective therapies. When COVID-19 becomes life-threatening it is primarily because the immune defense overreacts with a cytokine storm and hyperinflammation that destroys healthy tissue in the lungs, the circulatory system, and other places. Older people and heart failure patients already suffer from chronic low-grade, uncontrolled inflammation, to which nutrient deficiencies contribute and make the patients increasingly vulnerable. This also applies to people with metabolic syndrome and diabetes, many of which are overweight. For that reason, scientists affiliated with universities and research centers in Norway, Sweden, and Russia have searched the scientific literature to find studies that focus on whether supplementation with vitamin D, selenium, and zinc can help prevent a COVID-19 infection from escalating and becoming life-threatening.
This almost sounds too good to be true, but scientists from Germany and the United States have discovered that zinccombined with a compound found in cocoa beans, coffee beans, tea leaves, and grapes is able to activate a particular molecule that protects against oxidative stress. In ageing, oxidative stress holds a key role. It is caused by an imbalance between harmful free radicals and protective antioxidants. Although anti-ageing is normally conceived as something that can delay the exterior signs of ageing, it is really more important to slow down internal ageing such as atherosclerosis, fatigue, dementia, and early death in worst case. Many people lack zinc, and deficiencies of this nutrient are widespread and typically observed among vegetarians, vegans, older people, and pregnant and breastfeeding women. What the scientists are telling us now is that it is good for us to enjoy a little dark chocolate, coffee or tea in order to benefit even more from the zinc we get.
Everyone is affected by electromagnetic radiation from cell phones, device screens, the electricity supply and other electric systems. The brain’s neurons are particularly vulnerable, especially because electromagnetic radiation can increase the neuronal uptake of calcium ions, which makes the neurons overactive and may even cause them to perish. A study published in News Medical Life Sciences shows that too much calcium in the brain increases the risk of Alzheimer’s disease and digital dementia in young individuals. The increased electromagnetic radiation also generates loads of free radicals in the body that can cause oxidative stress and cellular damage because it outperforms the body’s different antioxidants. This was described in an article published in The Journal of Microscopy & Ultrastructure that also mentions how electromagnetic radiation can cause stress, headaches, fatigue, anxiety, and other symptoms.
- and 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.
The majority of sexually active people contract HPV (human papilloma virus), of which there are several types. Normally, the infection goes away by itself but in some cases it becomes chronic. This increases the risk of serious cell changes in the cervix which, in worst case, can result in cervical cancer. An American study has found that having adequate levels of five different antioxidants – albumin plus vitamins A, B2, E, and folic acid – may lower papilloma virus infections that are linked to cervical cancer.
- and some good dietary advice
AMD (Age-related Macular Degeneration) is a common eye disease that impairs your reading vision in particular. High-dosed supplementation with vitamin C, vitamin E, zinc and other antioxidants has been shown to help. The recommendation of these nutrients is based on documentation from a large American research project and demonstrate that normal recommendations (DRI = Daily Reference Intake) are inadequate as treatment for various disorders. There are also different foods that are highly relevant for preventing AMD or as part of a treatment against the condition.
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.
Critically ill patients often suffer from inflammation and oxidative stress, which is an imbalance between harmful free radicals and protective antioxidants. In worst case, this may result in tissue damage and organ failure. It turns out vitamin C is a powerful antioxidant with a therapeutic potential. According to a new systematic review article and meta-analysis, therapy with large quantities of intravenous vitamin C helps shorten the duration of the hospital stay for critically ill patients without any side effects.
Vitamin C is important for the immune system, the nervous system, energy turnover, connective tissue, hormone production, and numerous biochemical processes. Vitamin C is also an important antioxidant that protects cells and tissues against oxidative stress and hyperinflammation that cause virus infections to become dangerous. According to a new review article that is published in Nutrients, lack of vitamin C is widespread in underdeveloped, low-income countries but also occurs in industrialized countries with higher income levels. Also, the majority of Danes fail to consume the recommended amount of fruit and vegetables that are rich in vitamin C, plus a number of factors can increase the need for the nutrient.
Kidney stones is a painful and quite common problem. The diet plays a major role and according to a large American population study published in Nutrients, selenium may help prevent the condition. The authors mention that selenium-containing proteins and antioxidants have preventative mechanisms and due to the widespread problems with selenium-depleted farmland, they say that selenium supplementation may be a good way to prevent and manage kidney stones and other pathological changes.
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.
Millions of people take painkillers such as Panadol or Calpol that contain paracetamol, and an estimated one billion people or so lack selenium due to nutrient-depleted farmland. This is an unfortunate cocktail because being deficient of selenium increases the risk of using paracetamol, so even the recommended dosage burdens the liver to such an extent that it causes toxicity and increase the risk of side effects. This was demonstrated in a collaborative study carried out by Bath University in England and Southwest University in China.
– and could even make them more dangerous
Selenium is of vital importance to a strong immune defense. Still, selenium deficiency is a common problem and it increases the risk of viral infections such as influenza and the coronavirus from China, which is feared to turn into a global pandemic. It is a problem that selenium deficiency in infected animals and humans causes the virus to mutate and become more aggressive. Because of selenium’s important role as a powerful antioxidant, being deficient of this micronutrient may leave the body vulnerable to oxidative stress, which can cause tissue damage and complicate the virus infection. It is therefore important to get enough selenium at all times, as it also increases our resistance towards other viral infections such as herpes, HIV, and hepatitis, according to an article published in Nutrients.
It is commonly known that pregnant diabetics have an increased risk of developing an eye disease called diabetic retinopathy. The diet plays a major role and it appears that a vitamin C deficiency increases the risk, according to a Danish study of pregnant type 1 diabetics that is published in the journal Antioxidants. The authors also mention that vitamin C is a vital antioxidant that protects cells and tissues against oxidative stress caused by free radicals.
Chronic heart failure is a potentially life-threatening condition that affects millions of people worldwide. A group of scientists recently looked at the relation between chronic heart failure and zincdeficiency and how zinc supplementation can improve heart health by various accounts. The scientists also investigated why zinc deficiencies are so common. Their study is published in the Journal of Cardiac Failure.
Vitamin C is of vital importance to our immune defense, and it serves as a powerful antioxidant to protect cells and tissues. Large quantities of vitamin C are able to improve lung function in patients with chronic obstructive pulmonary disease (COPD) and other chronic lung disorders. This was demonstrated in a large meta-analysis published in International Journal of Chronic Obstructive Pulmonary Disease.
Heart failure is when the heart loses power and is no longer able to deliver blood to the different parts of the body. Typical symptoms are shortness of breath and physical exhaustion. There may also be symptoms like fluid retention, persistent coughing, chest tightness, increased sweating, or cold sensitivity. Chronic heart failure may be caused by different things, and it is a life-threatening condition. However, according to a study that is published in Journal of Clinical Investigation, magnesium supplementation can improve a type of heart failure called diastolic dysfunction. Previous studies have demonstrated that supplements of Q10 can also improve cardiac function in patients with heart failure.
Magnesium is required for a well-functioning immune defense and for controlling inflammatory processes that are vital to our health. Magnesium also appears to protect against COVID-19 and other infections and the development of cancer, according to a review article published in Journal of Health, Population, and Nutrition. Our modern, refined diet, stress, ageing, stimulant abuse, and different types of medicine also contribute to the widespread problems with magnesium deficiency.
Type 2 diabetes and early stages of the disease such as insulin resistance are spreading like a bushfire. The good news is that if you consume many antioxidants from fruit, vegetables, berries, tea, and dark chocolate and limit your intake of alcohol, you can lower your risk diabetes risk. This was shown in a new study that is published in the European journal Diabetologia, which focuses on diabetes research.
Elevated blood pressure is the main cause of stroke, cardiovascular disease and early death. For quite some time, there has been evidence that intake of fruit and vegetables affects the risk of developing elevated blood pressure. Science has not yet studied if this is due to the antioxidants in our diets, but a team of French scientists has looked closer at this. The researchers found that the total amount of antioxidants in our diet may lower by 15 percent the risk of elevated blood pressure. The potassium in fruit and vegetables also play a determining role in blood pressure management, and the same goes for Q10 – provided you take quality supplements with proper absorption.
Cardiovascular diseases are widespread and one of the major causes of death. The risk is increased by factors such as ageing, diabetes, and overweight. One of the underlying causes is oxidative stress, which is an imbalance between free radicals and antioxidants. Q10, which is involved in cellular energy turnover, happens to be one of the most powerful antioxidants. According to a review article that is published in the scientific journal Antioxidants, supplementation with Q10 can reduce oxidative stress and cardiovascular mortality. It can also improve quality of life and increase the chances of survival. Generally speaking, Q10 has a huge potential for anyone with a desire to remain healthy, and it is important to choose a supplement with documented quality and bioavailability.
- and oxidative stress
The body uses inflammation as part of its normal immune response to infections and tissue damage. If inflammation becomes chronic, however, it can be extremely dangerous. What happens is that it bombards the body with free radicals. This leads to oxidative stress and increases the risk of cell damage, overweight, and chronic diseases like type 2 diabetes, cardiovascular disease, autoimmune diseases, and different cancer forms. Diet and lifestyle play a major role, and according to a meta-analysis published in Frontiers in Pharmacology, Q10 supplementation can lower several markers of inflammation and oxidative stress.
Q10 is a unique and wonderful coenzyme with a key function in energy turnover and a role as a powerful antioxidant. The body produces the lion’s share Q10 for its own needs but the endogenous synthesis of the compound decreases with age. Moreover, cholesterol-lowering statins and bisphosphonates used to treat osteoporosis disrupt the body’s Q10 synthesis. Over the past decades, numerous studies have shown that Q10 supplementation can slow down the ageing process. Q10 is also useful in connection with heart failure and several other chronic ailments that typically occur in old age. This is described in a review article that is published in Mechanisms of Ageing and Development. With Q10 supplements, it’s important to choose pharmaceutical-grade products with documented quality and bioavailability.
Q10 is a unique compound with a key role in cellular energy turnover. It also serves as a powerful antioxidant. The body is able to synthesize most of the Q10 that it needs but as we grow older, our endogenous synthesis decreases, making us vulnerable in different ways. Cholesterol-lowering medicine and certain types of disease are also associated with lower levels of Q10 in the body. In a new review article, a group of scientists have scrutinized hundreds of Q10 studies that have been published in the years 2010-2020. They are able to conclude that Q10 is of particular importance to the heart, circulatory system, fertility, muscles, eyes and vision, and the ageing process. Things like migraines, chronic fatigue syndrome, and neurodegenerative diseases such as Parkinson’s and Alzheimer’s disease are also addressed. The body has difficulty with absorbing Q10 from food and supplements so it is recommendable to always choose a pharmaceutical-grade Q10 preparation with documented bioavailability.
- and there are no side effects
Rheumatism is the most widespread chronic disease in Denmark, and many people experience a worsening of the symptoms during the winter period. The majority of people take anti-inflammatory drugs for years, but this increases their risk of bleeding stomach ulcers and other side effects, not to mention premature death. The underlying cause is chronic inflammation and it is a problem that is not properly addressed. For decades, Nobel Prize-winners and other scientists have revealed what causes chronic inflammation and how the problem in many cases can be helped with various supplements that help cure the pain. In the following, we have summarized a lot of the research that has been conducted with vitamin D, fish oil, magnesium, selenium, zinc, and glucosamine, and we have looked at why the anti-inflammatory lifestyle has become such a health trend. It is essential to use supplements that contain the different ingredients in therapeutic doses and with a quality that allows the body to absorb and utilize the active compounds.
The cells in our body are constantly renewed but they can only divide a limited number of times. It all depends on the length of their telomeres, which one can compare to the protective plastic tips at the ends of shoelaces. Every time a cell divides, its telomeres are reduced in length, bringing the cell closer to its terminal phase. Now, a Chinese study has revealed that higher selenium intake is linked to increased telomere length. Put differently, a higher selenium intake contributes to protecting the cells and allowing them to replicate more times. This may likely postpone the ageing process and extend our lifespan, and there are other studies that suggest the same. It is worth making a note of the fact that selenium deficiency is widespread in Europe and throughout the world.
Cataracts is one of the leading causes of vision impairment and blindness. The risk is increased by old age and diabetes. According to a new study that is published in Frontiers in Nutrition, a relatively high selenium intake can protect against the disease. The scientists mention that because of selenium’s unique antioxidant properties this nutrient protects the cells in the eye and in other places against free radical damage and oxidative stress.
Selenium is a constituent of at least 25 essential proteins (selenoproteins), including several antioxidants that protect cells against oxidative stress and disease. A team of researchers from Munich in Germany has mapped out the mechanisms, which the selenium-containing antioxidants use to protect neurons in the brain against cell death. The scientists see a whole new potential with selenium because of its ability to protect against neurological disorders and cancer. It is problematic, however, that we have widespread selenium deficiency in our part of the world. Even if you stick with the official dietary guidelines, it is very difficult to get enough selenium to saturate all the different selenoproteins.
Everybody is exposed to heavy metals and other environmental toxins. They are present in the water, the air, our diet, in cosmetics, tobacco smoke, medicine, and countless other sources. These toxins increase our risk of cancer, neurological disorders, thyroid disease, autoimmune disease, and numerous other health problems. Also, the combination of different toxins causes a “cocktail effect” that we know very little about. According to a Spanish study of mice, which is published in Science of The Total Environment, a selenium-enriched diet has a protective effect.
The corona crisis has shed new light on the importance of having a strong immune defense, one that protects us against virus infections in the long run. Selenium plays a vital role for a number of different reasons but, unfortunately, there is widespread deficiency which increases the risk of infections and related complications. In a new review article that is published in International Journal of Molecular Sciences, the authors look closer at selenium’s role in connection with different types of virus infections such as influenza, HIV, and hepatitis with particular focus on COVID-19. The purpose of their article is to inform about new nutritional strategies that may contribute to a strong and well-functioning immune defense – mainly when it comes to COVID-19 and virus types that tend to mutate all the time.
Selenium is a trace element that supports over 30 essential selenoproteins, which have numerous functions. For the first time ever, a study of Mexican children reveals that lack of selenium delays the growth of pubic hairs and the development of sex organs in boys. It is a known fact that the agricultural soil in Mexico is low in selenium and that affects the entire food chain. The same is the case in Europe, for which reason farmers for decades have supplemented livestock with selenium as a way of improving fertility and preventing a number of deficiency problems. The big question is to what extent can selenium deficiency problems explain the impaired sperm quality that has been observed among young men? An estimated 500 million to one billon people worldwide get too little selenium from their diet.
Everyone knows that exercise and sports activities are good for you, but overtraining and high-performance sport may increase your risk of oxidative stress, which is associated with acute injuries, inflammation and later risk of neurodegenerative disease such as Alzheimer’s disease and ALS (amyotrophic lateral sclerosis). It is therefore a good idea to take antioxidant supplements, as this may help prevent both acute and chronic injuries. A comprehensive article published in the science journal Nutrients looks closer at the relation between free radicals and antioxidants, which have different functions in connection with various types of physical activity. This is especially the case with vitamins A, C, and E plus selenium and zinc. It is also important to make sure to get enough vitamin D and omega-3 fatty acids for counteracting inflammation and oxidative stress.
Regular sport is good for you, whereas arduous training and high-performance sport can result in physical injuries, infections, chronic inflammation, and serious diseases due to oxidative stress. This phenomenon occurs as a result of the increased energy turnover, which produces an excess of free radicals that cause damage to cells and tissues. Oxidative stress is also associated with impaired performance, poor restitution, and faster ageing. Our only natural defense against free radicals is the presence of antioxidants, and it is especially things like vitamin C, vitamin E, selenium, zinc, Q10, omega-3 fatty acids, and turmeric that protect against oxidative damage and improve recovery time. According to a review article published in Nutrients, supplements with the right doses of different nutrients can also help boost your physical and mental performance.
The kidneys cleanse our blood. Well-functioning kidneys are vital for the circulatory system and good health in general. Normal functioning of cells, including kidney cells, hinges on a host of different selenium-containing proteins and coenzyme Q10. Studies show that older people in many parts of the world, Europe included, have deficiencies of both substances. Therefore, a team of Swedish scientists conducted a study where they looked at selenium status and kidney function in a group of seniors. They gave selenium yeast and coenzyme Q10 or placebo to the participants for a period of four years. The results showed that the supplemented group as compared with the placebo group had improved kidney function according to several parameters. The positive effect on cellular energy metabolism, inflammation, and oxidative stress was attributed to the two supplements. The study is published in the science journal Nutrients.
Both physical traumas and critical illnesses are associated with inflammation and oxidative stress where free radicals can cause potentially life-threatening damage to cells and tissues. Traumas are estimated to be the cause of one in ten deaths. New research suggests that early intervention with selenium may shorten the hospital stay including the days spent in intensive care and reduce total mortality. This was shown in a study published in Frontiers in Nutrition where the researchers looked closer at selenium’s unique antioxidant properties and anti-inflammatory effect.
– and many other things
Vitamin B2, also know as riboflavin, is found in different foods and in supplements containing multivitamins and strong B-vitamins. Most people are unaware that the vitamin has a host of important functions, which are especially relevant for energy levels, the nervous system, the psyche, the body’s iron metabolism, vision, skin, and lips. A study that is published in Neurology also shows that taking large amounts of vitamin B2 can help prevent migraine headaches. It appears that vitamin B2 deficiency is a common problem because of stress, ageing processes, unhealthy diets, the use of birth control pills, medicine, and certain other causes. In the following, you can read more about this exciting yet overlooked vitamin and find out how best to utilize vitamin B2 from your diet or from supplements.
Vitamin B3 has a therapeutic effect in the treatment of progressive muscle diseases, including mitochondrial myopathy that is caused by a defective cellular energy metabolism and which has no cure, according to a study from Helsinki University.
Most people think of vitamin C in connection with the immune defense, but as it turns out, the largest concentration of vitamin C is actually found in the brain. This is because vitamin C is enormously important for the energy turnover, the nervous system, and the cognitive skills, and this is described in a new review article. There is also evidence of widespread vitamin C deficiency, which may eventually impair cognitive skills and increase the risk of dementia and Alzheimer’s disease. If a pregnant woman lacks vitamin C, it can disrupt the development of the baby’s brain. There is a number of factors that increase our need for the nutrient, so the big question is how much do we need to secure optimal brain function throughout life?
Air pollution is a serious health threat that affects the entire world. Previous studies show that it increases the risk of cardiovascular disease, among other things. We need new strategies for protection, and a recent Chinese study conveniently reveals that supplementation with vitamin Ccan protect the cardiovascular system against oxidative stress and other harmful impacts from air pollution. What we need to find out is how much vitamin C it takes to obtain a therapeutic effect.
Telomeres are protective caps at the end of our DNA strands. You can compare them to the small plastic aglets that prevent shoelaces from unraveling. For each time a cell divides, the telomeres become shorter. The length of telomeres conveniently indicates our biological age. Diet plays a role and according to a large population study, vitamin C intake is linked to telomere length. The same is the case with Q10 and selenium, according to Swedish research. Vitamin C, Q10, and selenium serve as unique antioxidants that protect the telomeres and the cells against damage caused by oxidative stress.
Many critically ill patients lack vitamin D to an extent that can be life-threatening. This also goes for patients hospitalized with COVID-19. A large meta-analysis concludes that supplementation with vitamin D can lower all-cause mortality and reduce the duration of patients’ stay in intensive care. In the meta-analysis, the researchers look at the mechanisms that enable vitamin D to regulate inflammation and oxidative stress, which can lead to organ failure in critically ill patients.
PMS (premenstrual syndrome) is quite common among women of childbearing age and can easily make their lives miserable for years, causing both physical and mental discomfort several days a month. A possible cause can be lack of vitamin D, and it looks as if high-dosed supplementation with the nutrient can relieve PMS by controlling inflammation markers and influencing the body’s antioxidant capacity. This was shown in an Iranian study that is published in Scientific Reports. It is worth noting that we need magnesium to activate vitamin D in order for the body to be able to use it optimally.
- even in smokers
It has been known for long that vitamin K2 is important for circulation and bone health. According to a new study, vitamin K2 also lowers the risk of cardiovascular disease in smokers and other nicotine users. This is because vitamin K2 counteracts oxidative stress and atherosclerosis. The scientists stress how important vitamin K2 is for public health, including otherwise unhealthy groups such as smokers.
- that is the common thread in most chronic diseases
Lack of dietary zinc may disrupt the immune defense and increase your risk of inflammation, which is the common thread in most diseases such as eczema, rheumatism, diabetes, and cancer. Zinc’s underlying mechanisms used to be relatively unknown, but a new study published in the science journal Immunology shows that zinc regulates the white blood cells of the immune system plus the formation of various proteins that are important for controlling inflammatory processes. Unfortunately, zinc deficiencies are widespread for a number of reasons.
We have relatively large quantities of zinc in our central nervous system where it plays a vital role in various physiological and pathological processes. Zinc is also important for brain development, various gene activities, the formation of new neurons, and the immune defense. What is more, zinc is a vital antioxidant that protects the brain against calcification and cell damage caused by oxidative stress. Zinc deficiency is a global problem and may be involved in a number of different neurological diseases – including stroke, cognitive impairment, Alzheimer’s disease, and depression, according to a new review article that is published in Biomolecules.
