Vitamin D3 (also known as Cholecalciferol) is actually a Secosteroid (very similar in structure to a steroid).
The supplemental form is most commonly derived from the oil of sheep's wool (lanolin). It can also be made from fish liver oil.
Most vitamins are made out of parts of several varieties of fish like cod. However, some companies make vegan vitamins, which are made of various plants like soy.
