The term vitamin D refers to vitamin D2, vitamin D3 as well as to their metabolites and analogues. Vitamin D2 (ergocalciferol) is derived from fungal and plant sources; vitamin D3 (cholecalciferol) is derived from animal sources. Super D3 is derived from lanolin, from sheep’s wool. Vitamin D usually acts as a hormone precursor, requiring two stages of metabolism before reaching hormonal form. Following absorption or endogenous synthesis, it is metabolized to 25- hydroxycholecalciferol (25(OH)D) in the hepatocytes. 25(OH)D is the major circulating form of vitamin D, but is not biologically active. Then, the biologically active hormone form, 1 alpha, 25-dihydroxycholecalciferol (1,25(OH)2D) is produced in the kidneys. Vitamin D receptors exist in a wide variety of tissues and organs.
