Vitamin D is 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.

Selenium has an overlooked role in sperm quality and healthy pregnancies. A team of scientists from Romania has looked closer at blood levels of different selenium-containing antioxidants and found that low levels are significantly correlated with poor sperm quality. The scientists also explain that lack of selenium increases the risk of pregnancy-related complications, miscarriage, and preterm delivery. Both selenium deficiencies and infertility are common problems so selenium supplementation may be worth considering. For decades, Danish farmers have added selenium to animal fodder as a way of improving the fertility and general health of the animals.

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?

Diabetes damages the circulatory system in a number of ways that are linked to impaired quality of life and early death. A meta-analysis shows that if type 2 diabetics take supplements of Q10 it lowers their risk of cardiovascular disease by reducing levels of total cholesterol and LDL cholesterol. Another positive effect of Q10 is that it serves as a unique antioxidant that counteracts oxidative stress, which is a major cause of atherosclerosis and cardiovascular damage. One of the problems of using cholesterol-lowering statins is that it inhibits the body’s endogenous Q10 synthesis, but this is something one can compensate for. According to Danish research, it is also a good idea to limit your carbohydrate intake and follow the new dietary guidelines that help stabilize blood sugar levels.

Benign paroxysmal positional vertigo (BPPV) impairs many people’s quality of life and ability to work. The dizzy spells typically occur when they shift position. According to a study from Korea which is published in Neurology, supplementing with vitamin D and calcium may lower the risk of recurring spells of dizziness. It is important to balance your calcium intake with magnesium.

Selenium is involved in a number of different metabolic processes and works as an antioxidant, which protects the heart and cardiovascular system, but it is difficult to get enough of the nutrient from the diet. According to a new American mouse study, selenium supplementation can speed up the metabolic processes and protect against overweight. A Swedish study of seniors published some time ago showed that supplements of selenium and Q10 has a positive effect on quality of life and lifespan.

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.

Magnesium plays a role in a variety of enzyme processes that are involved in 80 percent of the body’s metabolic functions, and a magnesium deficiency can affect different genes and diseases. Such deficiencies are very common, especially among women. A Russian study of pregnant women and women with different types of hormonal imbalances shows that four weeks of magnesium supplementation can improve health and quality of life by several parameters.

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 C happens 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.
