Used as a nutritional supplement for many years, brewer's yeast is a form of fungus that is a by-product of the beer-brewing process. Brewer's yeast supplements are available in many forms, with powder and tablets being the most common. Brewer's yeast has a wide range of benefits, from repelling insects to controlling diarrhoea. Although brewer's yeast is essentially beneficial to health, contact a medical practitioner before using it.

B Complex Vitamins

Brewer's yeast is an excellent source of all of the B complex vitamins except vitamin B12. B complex is essential for maintaining proper bodily functions and ensuring proper health. According to Cancer.org, the official website for the American Cancer Society, vitamin B9, also known as folic acid, has been linked to cancer prevention. Vitamins B1 and B3 are vital in assisting cells in energy production, while vitamin B7 helps the body make use of the foods we eat, and assists in hormone production. When using brewer's yeast on foods, sprinkle it on your food after preparation, as cooking process destroys B vitamins.

Selenium and Chromium

Brewer's yeast is a rich source of two key minerals, selenium and chromium. According to the Mayo Clinic, promising research has linked selenium to prostate cancer prevention. The results, however, are not conclusive, and more research is needed. Selenium also provides a boost to the immune system. Chromium is needed by the body to regulate blood sugar levels. The cells require chromium to transport insulin through the cell membranes. Chromium is particularly high in Glucose Tolerance Factor, an organic compound that prevents imbalances between glucose and insulin, which can lead to hypoglycaemia and diabetes.

Essential Amino Acids

An excellent source of protein, brewer's yeast contains the nine essential amino acids required to make a complete protein molecule. It actually yields much more protein by weight than whole wheat flour. Protein is essential for proper tissue maintenance and repair. In addition, brewer's yeast makes an excellent alternative source of protein for vegetarians.


Brewer's yeast is considered a probiotic, which helps maintain the body's optimum microbial balance. While not confirmed by conclusive research, brewer's yeast may raise high density lipoprotein, or HDL, which is the "good" form of cholesterol.
