According to the University of Maryland Medical Center, brewer’s yeast is made of dried cells of the organism Saccharomyces cereisiae--the same organism used to make bread and beer. Technically a fungus, yeast converts sugar to alcohol when used in food preparation. Because it’s a living organism, however, it’s also a rich source of many nutrients and is a probiotic.


Mother Nature, a compendium of information about natural remedies, cites Dr. Richard Anderson regarding the nutritional benefits of brewer’s yeast. According to Anderson, brewer's yeast is a rich source of chromium, a mineral used to transport sugar across cell membranes. He notes that because of this, some people use brewer's yeast to reduce the symptoms of (or even prevent) diabetes.

B Vitamins

Brewer’s yeast is a rich source of B vitamins, according to Herbal Home Remedies. These vitamins perform various functions in the body. Many B vitamins are involved in metabolism and therefore help cells produce energy from consumed nutrients. Herbal Home Remedies says supplementation with brewer’s yeast supplies vitamins B1, B2, B5, B6 and B9. “These vitamins help in breaking down fats, carbohydrates, as well as proteins, which provide [the body] with … energy,” the site says.


Vegan Health lists another important vitamin found in brewer’s yeast: cyanocobalamin. This vitamin is essential to normal body function; a deficiency results in pernicious anemia, a severe blood disorder. There are many sources of cyanocobalamin, but it’s nearly impossible to find outside of animal products, meaning vegans generally have to take supplements. Brewer’s yeast, however, is a rich, vegan source of this essential nutrient.
