- Dosing considerations for Brewer's Yeast.
Brewer's yeast is used for diarrhea, the common cold and other upper respiratory tract infections, influenza, swine flu, loss of appetite, acne, premenstrual syndrome (PMS), recurring boils on the skin (furunculosis), and type 2 diabetes. It has also been used as a source of B vitamins, chromium, and protein.
Possibly Effective for...
- Premenstrual syndrome (PMS). Taking a specific brewer's yeast preparation (Sillix Donna by Giuliani) that also contains vitamins and minerals by mouth might decrease symptoms of PMS.
Insufficient Evidence to Rate Effectiveness for...
- Swelling of the colon (colitis) due to the bacteria Clostridium difficile. There is a report that taking brewer's yeast by mouth for 4 months along with vancomycin for 30 days may help treat colitis caused by the bacteria Clostridium difficile and prevent recurrence.
- Diabetes. Early research suggests that taking brewer's yeast containing chromium by mouth for 8 weeks can reduce blood sugar levels in people with diabetes. It may also reduce the need to use certain diabetes medications.
- High cholesterol. Early research suggests that taking brewer's yeast containing chromium by mouth for 8 weeks can decrease blood levels of total cholesterol and increase levels of high-density lipoprotein (HDL or "good") cholesterol in people with high cholesterol.
- Upper respiratory tract infection, including the common cold and flu (influenza). Early research shows that taking a specific brewer's yeast product (EpiCor by Embria Health Sciences) reduces the risk of the common cold or flu in healthy people who recently received flu shots. This product also helps symptoms resolve faster.
- Loss of appetite.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
