A completely natural primary Brewer's Yeast (Saccharomyces cerevisiae) that provides a source of amino acids, B-complex vitamins and minerals. Most Brewer's Yeasts are derived from the fermentation of beer: Such fermentation involves using grain (rice, wheat, etc.) malt, active yeast and the dried flowers of hops. Solgar's Brewer's Yeast is produced from beet molasses under carefully controlled conditions. After fermentation, the yeast is collected and dried, using special techniques to preserve its protein, vitamin and mineral content.
