Yeast

The B vitamins thiamine, riboflavin, niacin, pantothenic acid, pyridoxine, folate, and biotin are particularly abundant in brewer's yeast. Brewer's yeast and nutritional yeast both contain biotin, but the levels differ depending on the type.

Beer production and bread leavening both use brewer's yeast, commonly known as dry active yeast. On the other hand, nutritional yeast, an inactive type of yeast, is frequently used to make non-dairy cheese. Up to 21 mcg of biotin, or 69% of the DV, may be found in 2 tablespoons of nutritional yeast (16 grams). The amount of biotin in a typical 2.25 teaspoon (7-gram) packet of active dry yeast for baking, on the other hand, is 1.4 mcg, or 5% of the DV.
