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.

Several B-vitamins need to be converted into other forms before they are activated for a wide range of functions. However, enzyme defects, alcohol, medication, and aging processes can make this difficult. The form of vitamin D that we produce from the sun or get from supplements is also inactive, and factors like obesity, aging processes, and a lack of certain minerals can make it difficult to make the active form. Conversion of vitamin K1 into vitamin K2 requires a well-functioning gut flora. Optimal utilization of Q10 requires a specific selenium compound. This means that an inability to activate vitamins and Q10 can result in chronic fatigue, many serious diseases, and in the worst case, early death.

Several studies have shown that optimizing your blood vitamin D levels with supplementation reduces the risk of contracting respiratory infections such as COVID-19. A new Hungarian study, published in Nutrients, has also found that very high doses of vitamin D given to hospitalized COVID-19 patients can reduce the risk of prolonged hospital stays and death due to severe complications.

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.

According to a University of Zurich study published in Nature Aging, daily intake of just one gram of omega-3 from supplements or a serving of fish can slow down the aging processes and extend lifespan. The effect can even be improved by combining omega-3 fatty acids with larger doses of vitamin D supplements and strength training.

There is a lot of evidence to suggest this. Selenium is involved in some unique selenium-containing antioxidants that protect our cells from free radicals, aging processes, and premature cell death. This is highlighted in a new study from Osaka University in Japan, which was conducted on stem cells.

Diet, smoking, and aging processes increase the risk of developing chronic obstructive pulmonary disease (COPD), a condition that causes millions of deaths worldwide. According to a meta-analysis published in Nutrients, vitamin D supplementation seems to improve lung function.

- 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.

An increasing number of people are being diagnosed with ADHD, which affects neurological development, learning, and social interactions. There is growing evidence that the brain and nervous system often lack nutrients that are necessary for several vital functions, or that they are exposed to harmful substances. A review article published in Cureus shows that supplements of vitamin D, magnesium, and fish oil can improve symptoms.
