Derived from the yeast Saccharomyces cerevisiae, brewer?s yeast was originally extracted from the top layer in beer vats. Brewer?s yeast is a rich source of important nutrients, including Niacin, Riboflavin, Pantothenic Acid, Thiamin, Pyridoxine, Folic Acid, para-amino benzoic acid (PABA), Biotin, Copper, Iron, and Amino Acids. It is not a complete source of B vitamins, as is commonly mistaken, for it does not contain vitamin B-12. Its nutritional content may vary due with different products and methods of storage. Brewer?s yeast may be a beneficial source of proteins for people following strict vegetarian diets.
Tablets, 4-5 g daily.
Brewer?s yeast is regarded as generally non-toxic.
There are no known drug interactions or contra-indications for brewer?s yeast.
