Is Biotin (B7) vegan?
Depends
Biotin is microbially fermented or synthesized — usually vegan, but some 'natural' brands use egg yolk extract.
What it is
A B-vitamin essential for hair, skin and nail health.
Why depends
Most commercial biotin is synthetic or fermentation-derived. A handful of 'whole-food' supplements list 'egg yolk biotin' — avoid those.
