The vitamin D endocrine systems plays a critical role in calcium and phosphate homeostasis. The active form of vitamin D, 1,25-dihydroxyvitamin D3[1,25(OH)2D3], binds with high affinity to a specific cellular receptor that acts as a ligand-activated transcription factor.

Sources of vitamin D for humans.
International journal for vitamin and nutrition research. Internationale Zeitschrift fur Vitamin- und Ernahrungsforschung. Journal international de vitaminologie et de nutrition, 2021Both vitamin D insufficiency and deficiency are now well-documented worldwide in relation to human health, and this has raised interest in vitamin D research. The aim of this article is therefore to review the literature on sources of vitamin D.

Vitamin D deficiency aggravates COVID-19: systematic review and meta-analysis
Critical reviews in food science and nutrition, 2020There is still limited evidence regarding the influence of vitamin D in people with COVID-19. In this systematic review and meta-analysis, we analyze the association between vitamin D deficiency and COVID-19 severity, via an analysis of the prevalence of

Vitamin D and Vitamin D Dependency
2015Administration of large doses of vitamin D2 brought about a marked increase of 25-hydroxyvitamin D in both the patients with vitamin D dependency and hypophosphatemic vitamin D-resistant rickets. During the administration of vitamin D2, increment of 1,25-dihydroxyvitamin D was marked in hypophosphatemic vitamin D-resistant rickets, but far smaller in ...

The primary source of vitamin D is the skin, following exposure to ultraviolet radiation. Vitamin D is well known for its effects on stimulating calcium absorption and is thus essential for maintenance of normal bone. It is also important for muscle function and has more recently been implicated in protection against several diseases including diabetes.

SUMMARYDuring the past decade, an explosion of information has become avdable on the metabolism and function of vitamin D whch is of great importance to clinicians in the treatment of metabolic bone disease. We have learned that vitamin D is the precursor of at least one hormone and that ths hormone carries out functions in calcium and phosphorus ...
