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 Q10 and 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.

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

Over the past decades, numerous studies have linked low selenium levels in the blood to cardiovascular disease, cancer, increased risk of infection, thyroid disorders, and several other diseases. Due to the widespread problems with selenium deficiency, supplementation with this nutrient is of potential value to our general health. In a review article that is published in Oxidative Medicine and Cellular Longevity, the authors look at selenium’s role in connection with a host of different diseases and metabolic disorders.

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

Q10 is a key element in the cellular energy turnover and also serves as a protective antioxidant. The human body is able to make most of its own Q10 but as we grow older, our endogenous Q10 synthesis decreases, and this is also the case with certain diseases and as a result of using specific types of medicine. A large meta-analysis has shown that Q10 supplementation is able to reduce chronic fatigue in healthy individuals as well as in people with diseases. Apparently, taking larger doses for longer periods of time works best for energy levels. It is important to choose a Q10 supplement that has the right quality and comes with documentation to ensure that the Q10 molecules are absorbed properly in the blood and reach the energy-producing powerhouses of the cells.

Photodynamic therapy is a kind of light therapy that is used to treat skin cancer, psoriasis, and other skin diseases. According to a review article published in Nutrients, vitamin D supplementation can improve the outcome of the treatment. In fact, vitamin D appears to have several positive effects on skin health. Taken in large doses, the vitamin can even repair skin damage caused by sunburns.

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.

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.

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.

Fish contains vitamin D, omega-3 fatty acids, selenium, and iodine, all of which are important for the fetus’ brain and development. However, fish also contains mercury and that discourages many pregnant women from eating fish. According to a new study that is published in NeuroToxicology, eating fish during pregnancy is actually not harmful at all, on the contrary, and the scientists behind the study argue that the precautionary guidelines need to be revised. Apparently, the selenium content in fish and seafood determines if mercury is dangerous or not.

Selenium is a trace element that supports well over 25 different selenoproteins, which are important for our energy turnover, blood sugar balance, metabolism, cell protection, and a host of other essential functions. A group of scientists from Rutgers University in New Jersey, USA, has just uncovered the mechanisms involved in getting selenium into the “engine room” of the cells, from where it is metabolized into the different selenoproteins. According to the scientists, this new insight into the metabolism of selenium may lead to new therapies that can treat a variety of diseases such as diabetes, metabolic disorders, and cancer.

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