Although some people use the terms interchangeably, brewer’s yeast and nutritional yeast are different substances and both are different from common baker’s yeast. Brewer's yeast is often taken as a nutritional supplement due to its rich supply of protein, B vitamins, chromium and selenium.
Brewer's yeast stimulates the body's immune function and contributes to overall health by supporting the regeneration of cells. People who take brewer’s yeast in addition to a healthy diet and exercise program usually show lower blood glucose levels, reduced total cholesterol and low density lipoproteins ("bad" cholesterol).
