Does yeast contain an allergen?

Yeast is not one of the allergens that food labels must declare in the US, the UK, Europe or the Gulf. Open Food Facts does not link it to an allergen, and Bravoora’s label checker does not read the name as one.

Is yeast vegan?

Yes. Yeast is vegan and vegetarian: Open Food Facts records nothing from an animal in it.

Sources

An allergen is stated only when two of three checks agree: the Open Food Facts record, Bravoora’s label checker, and the ingredient’s own name or family (oat flour is oats, a cheese is milk). Every name where they disagree waits for a person to review it.
