What is brewers yeast?
Brewers yeast is a by-product of the beer brewing process. Brewers yeast is a single cell organism of the group Saccharomyces cerevisiae used by brewers to ferment raw beer and convert the carbohydrates to alcohol and carbon dioxide. During the fermentation process, the yeast absorbs many nutrients including several essential minerals. The yeast cell itself is almost a half, high-quality, single cell protein with an exceptional amino acid balance and contains an abundance of vitamins, especially B complex vitamins.
