Health Notes

Brewer's Yeast

Brewer's Yeast
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Type 2 Diabetes
Dose: 9 grams per day
Chromium-rich brewer's yeast has been shown to be useful in treating type 2 diabetes in several ways, including by improving glucose tolerance.(more)
Infectious Diarrhea
Dose: Three capsulesor tablets three times per day
Supplementing with brewer's yeast has been shown to improve immune function and change the flora living in the intestine, and may relieve infectious diarrhea.(more)
Type 2 Diabetes
Dose: 9 grams per day

Medical reports dating back to 1853, as well as modern research, indicate that chromium-rich brewer's yeast (9 grams per day) can be useful in treating type 2 diabetes.1, 2 In recent years, chromium has been shown to improve glucose levels and related variables in people with glucose intolerance and type 2, gestational, and steroid-induced diabetes.3, 4 Improved glucose tolerance with lower or similar levels of insulin have been reported in more than ten trials of chromium supplementation in people with varying degrees of glucose intolerance.5 Chromium supplements improve glucose tolerance in people with type 2 diabetes,6 apparently by increasing sensitivity to insulin.7 Chromium improves the processing of glucose in people with prediabetic glucose intolerance and in women with diabetes associated with pregnancy.8, 9 Chromium even helps healthy people,10 although one such report found chromium useful only when accompanied by 100 mg of niacin per day.11 Chromium may also lower levels of total cholesterol, LDL cholesterol, and triglycerides (risk factors in heart disease).12, 13

A few trials have reported no beneficial effects from chromium supplementation.14, 15, 16 All of these trials used 200 mcg or less of supplemental chromium, which is often not adequate for people with diabetes, especially if it is in a form that is poorly absorbed. The typical amount of chromium used in research trials is 200 mcg per day, although as much as 1,000 mcg per day has been used.17 Many doctors recommend up to 1,000 mcg per day for people with diabetes.18

Supplementation with chromium or brewer's yeast could potentially enhance the effects of drugs used for diabetes (e.g., insulin or other blood sugar-lowering agents) and possibly lead to hypoglycemia. Therefore, people with diabetes taking these medications should supplement with chromium or brewer's yeast only under the supervision of a doctor.

Infectious Diarrhea
Dose: Three capsulesor tablets three times per dayBrewer's yeast supplementation has been shown to alter immune function and the flora living in the intestine, and may relieve infectious diarrhea. Three capsules or tablets of brewer's yeast three times per day for two weeks was reported to improve three cases of infectious diarrhea caused by Clostridium difficile.1 Animal research has confirmed that brewer's yeast helps fight this unfriendly bacterium.2 (Note that real brewer's yeast is not identical to nutritional, or torula, yeast and that when asking for "brewer's yeast" in health food stores, people are often directed toward these other products. Real brewer's yeast is bitter, whereas other health food store yeasts have a more pleasant taste.)

Brewer's yeast is the dried, pulverized cells of Saccharomyces cerevisiae, a type of fungus, and is a rich source of B-complex vitamins, protein (providing all essential amino acids), and minerals, including a biologically active form of chromium known as glucose tolerance factor (GTF). Brewer's yeast is usually a by-product of the brewing industry and should not be confused with nutritional yeast or torula yeast, which are low in chromium.

    Comments about GNC Brewer's Yeast 500 mg:

    This is an old home remedy that works. If you take 1 tablet twice a day, mosquitoes do not like you.(It takes about 1 1/2 weeks for it to start working. My husband works in farm fields at night, he was using 1 can of off deep woods every 2 days, and was still getting bit. I told him about brewers yeast, he started using, and now he doesn't buy off.
