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.
Brewer'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. Animal research has confirmed that brewer's yeast helps fight this unfriendly bacterium. (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.)
