calciferol

(kăl-sĭf′ə-rôl′, -rōl′)

calciferol

A vitamin D derived from steroids by breaking the B ring’s 9-10 bond (e.g., cholecalciferol and ergocalciferol), which is produced by the body when exposed to UV light. Supplemental vitamin D3 reduces all-cause mortality, especially in elderly women, an effect not seen with vitamin D2, alfacalcidol or calcitriol (intrinsic vitamin D). However, too much or too little vitamin D is associated with increased mortality in a U-shaped risk curve.
