Is vitamin D3 vegan?

Is vitamin D3 vegan?
Why
vitamin D3 is usually extracted from sheep's wool grease, so the standard version is an animal product; a lichen or algae version is vegan.
What to use instead
algae oil — It does exactly the same job in coffee, cooking and baking, with no change in method.
How to check a label
Ingredient lists are legally required to name allergens such as milk and egg in bold, which catches most hidden animal ingredients. E-numbers and processing aids are the gap: E120, E441, E542, E904 and E920 are animal-derived, and processing aids often go unlisted. When in doubt, look for a certified vegan mark or ask the manufacturer directly — most reply within a few days.
In depth
The longer answer
Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin essential for calcium absorption and bone health. It is naturally produced in human skin upon exposure to sunlight, but dietary sources are limited. Most commercial D3 is derived from lanolin, a waxy substance extracted from sheep's wool, which raises questions for those following a plant-based lifestyle.
The vegan status of vitamin D3 is not straightforward because the primary commercial source is lanolin from sheep's wool, making it unsuitable for vegans. While sheep are not killed for lanolin, the wool industry often involves animal exploitation. However, some brands now produce vegan D3 from lichen, a plant-like organism, offering a cruelty-free alternative that is chemically identical to animal-derived D3.
To ensure a supplement is vegan, check the label for 'vegan' certification or look for 'lichen-derived' or 'plant-based vitamin D3.' Avoid terms like 'lanolin' or 'cholecalciferol' without a vegan source listed. If in doubt, choose vitamin D2 (ergocalciferol), which is always vegan and derived from fungi, though it may be less effective at raising blood levels than D3.
