Recently we were asked where most vitamin D3 supplements come from. Most actually come from two animal sources: fish oils (from the skin of fatty fish) or sheep lanolin (the waxy substance secreted by the glands in sheep skin). Common vegetarian vitamin D supplements are vitamin D2 (ergocalciferol)-a derivative of ergosterol. The majority of the scientific community believes D3 (cholecalciferol) is superior to the vitamin D2 form.
