Brewer's yeast is one of the best-known nutritional supplements. It is obtained from cereal fermentation, such as barley. It tends to have a bitter aftertaste, so it is processed into de-bitterised yeast. It is available as a powder or in flakes, that can be added directly to food, or in tablet or capsule form.
It is very high in fibre and proteins of high biological value, especially rich in the amino acid lysine, and it contains glutathione, a tripeptide with antioxidant properties. It also contains B vitamins and several minerals, such as selenium, calcium, zinc and iron.
As a source of vitamins, minerals and amino acids, supplementation with brewer's yeast supports hair, skin and nail care. Minerals such as zinc and selenium support proper immune system function and fibre supports bowel movement.
It is advisable to consult with a healthcare professional or nutrition expert if you have any questions about this nutritional supplement, such as how much to take or for how long.
