Brewer's Yeast is a type of fungus, specifically a strain of Saccharomyces cerevisiae, commonly used in the production of beer and bread. It ferments sugars, converting them into alcohol and carbon dioxide, which helps dough rise and gives beer its bubbles. This yeast is rich in nutrients, including B vitamins, protein, and minerals. In addition to its culinary uses, Brewer's Yeast is often taken as a dietary supplement for its potential health benefits. It may support digestive health, boost the immune system, and provide energy. However, individuals should consult a healthcare professional before starting any new supplement.
