This yeast is grown on enriched purified cane and beet molasses under carefully controlled conditions. This is a primary grown yeast and is therefore not a brewery by-product as is brewer's yeast. This ensures freedom from Candida albicans yeast. NOW Foods' Nutritional Yeast Flakes are a vegan/vegetarian dietary supplement. Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients.
