BoulardiiMAX is a probiotic supplement of Saccharomyces boulardii, a non-colonizing yeast species. It is a non-pathogenic yeast strain that is not related to the yeast group to which Candida belongs. Saccharomyces boulardii has been isolated from the skins of tropical fruits found in Indochina. The Indigenous population of Indochina has long used these fruit skins to prevent and treat diarrhea.
Many quality human research studies have also indicated that Saccharomyces boulardii can be effective in preventing antibiotic-associated diarrhea, diarrhea caused by Clostridium difficile, as well as diarrhea caused by other types of bacteria. New research is also showing Saccharomyces boulardii as an effective addition to H. Pylori treatment.
