NOW&ampreg; pleasant tasting Nutritional Yeast Flakes are produced from a specially selected strain of Saccharomyces cerevisiae. This yeast is grown on enriched purified cane and beet molasses under carefully controlled conditions.&ampnbsp; This is a primary grown yeast and is therefore NOT a brewery by-product as is brewer's yeast.&ampnbsp; This ensures freedom from Candida albicans yeast.
