Vitamin D is a group of structurally related, fat-soluble compounds responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, along with numerous other biological functions. [1] [2] In humans, the most important compounds within this group are vitamin D 3 (cholecalciferol) and vitamin D 2 (ergocalciferol). [2] [3]
Because the newly discovered substance was the fourth vitamin identified, it was called vitamin D. [92] The 1928 Nobel Prize in Chemistry was awarded to Adolf Windaus, who discovered the steroid 7-dehydrocholesterol, the precursor of vitamin D. Potential anticancer roles of the vitamin D metabolite calcifediol were observed epidemiologically by ...
22-Dihydroergocalciferol is a form of vitamin D, also known as vitamin D 4. [2] It has the systematic name (5Z,7E)-(3S)-9,10-seco-5,7,10(19)-ergostatrien-3-ol. [1]

Ergocalciferol, also known as vitamin D 2 and nonspecifically calciferol, is a type of vitamin D found in food. It is used as a dietary supplement [3] to prevent and treat vitamin D deficiency [4] due to poor absorption by the intestines or liver disease. [5]
Vitamins have diverse biochemical functions. Vitamin A acts as a regulator of cell and tissue growth and differentiation. Vitamin D provides a hormone-like function, regulating mineral metabolism for bones and other organs. The B complex vitamins function as enzyme cofactors (coenzymes) or the precursors for them. Vitamins C and E function as ...
The Institute of Medicine in 2010 recommended a maximum uptake of vitamin D of 4000 IU/d, finding that the dose for lowest observed adverse effect level is 40,000 IU daily for at least 12 weeks, [25] and that there was a single case of toxicity above 10 000 IU after more than seven years of daily intake; this case of toxicity occurred in ...
