Saccharomyces boulardii info sheet on

We noticed that our friends at are still posting an old info sheet on Saccharomyces boulardii produced by one of the New York Buyers’ Club’s predecessor organizations, the PWA Health Group. Much of the scientific information displayed is still valid, though the Biocodex product, once available in the US only through convoluted importation processes (pioneered by PWAHG and others), is now readily available here under the tradename Florastor.

Here’s the introduction of the info sheet on  

Saccharomyces boulardii (SB) is a live yeast packaged in capsules and sold over the counter in Europe to treat diarrhea. Studies suggest that SB protects the gut from amebas and cholera, may keep candida from spreading, alleviates diarrhea caused by c. difficile, Crohn’s disease and diarrhea of unknown cause in PWAs, and traveller’s diarrhea.

We’ll add the capsule summary of Florastor’s utility from the NYBC website:

This “friendly” yeast has a proven ability to increase the immune response in the GI tract and has helped to control chronic diarrhea in some PWAs. Part of the way this works is to replenish vital intestinal flora that have the added benefit of competing for the site of other infections. It may be a good idea to use this product if you are taking antibiotics. One problem with chronic, long-term antibiotic use is that it can cause the eruption of a bacterial infection known as clostridium (C. difficile) which can cause serious diarrhea.
