Is vitamin-d vegan?

Vitamin D is a fat-soluble micronutrient frequently added to foods and dietary supplements. On ingredient labels, it typically appears in fortified products such as plant-based milks, breakfast cereals, fruit juices, and spreads. Manufacturers produce it synthetically, harvest it from wild-grown lichens, or generate it by exposing yeast and mushrooms to ultraviolet light, which converts natural sterols into the active vitamin.

This ingredient is classified as vegan because it is derived exclusively from plant, microbial, or synthetic origins rather than animal sources. While conventional vitamin D can be extracted from sheep wool grease, this entry covers versions produced through animal-free pathways, including ergocalciferol from yeast fermentation and cholecalciferol sourced from lichen. These processing methods yield a final compound that contains no animal tissues, secretions, or byproducts.
