Is vitamin D3 vegan?
Short answer
Often no, if it is made from lanolin (sheep’s wool). Vegan D3 can come from lichen; D2 is plant-derived. Read the supplement label.
Most cheap D3 is lanolin. NIH describes D2 and D3 as vitamin D forms; veganism is about the source.
Winter D supplementation is often advised for the whole population in northern countries.
