Brewer’s Yeast is from the Saccharomyces cerevisiae species, a one-celled fungus, which is naturally found on the skin of grapes and other fruits. This yeast is a favorite among vegans, vegetarians and nursing mothers. Just remember, it is not to be confused with baker’s, nutritional or torula yeasts as it is inactive and will not make bread rise! Use Anthony’s Brewer’s Yeast Powder on cereals, salads, baked goods, soups, sauces, or by blending it into smoothies. This yeast is derived from molasses and is in its purest form, causing it to be naturally bitter.
