What is Vitamin D?
Vitamin D is a fat-soluble vitamin that is critical for maintaining healthy bones and teeth. It also plays an essential role in immune system function. There are two main forms of vitamin D in supplements and fortified foods: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D3 is typically derived from animal sources, whereas vitamin D2 can be derived from plant sources, making it suitable for vegans.

Why People Avoid Vitamin D
People following a vegan diet may avoid vitamin D3 since it is commonly derived from animal sources such as fish liver oil and lanolin (from sheep's wool). Without clear labeling, it can be difficult to determine the source of vitamin D in a product, so it is often recommended to contact the manufacturer for more information. Vitamin D2 is considered a vegan-friendly alternative as it is derived from plant sources like yeast or fungi.
