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). Also, Vitamin D contributes to the normal functioning of immune system.
