Vitamin D3

Vitamin D, also known as cholecalciferol or the “sunshine vitamin”, is a fat-soluble vitamin produced by the body when skin is exposed to sunlight. Its two forms are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol).

Vitamin D3 is produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis. It can also be found in some foods and is available as a food supplement.
