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.

Once a BoulardiiMAX capsule is ingested, the Saccharomyces boulardii becomes quickly established in the intestinal tract.  There are a number of different mechanisms by which S. boulardii works within the intestinal tract:

  1. It inhibits pathogenic bacteria adhesion to the intestinal wall, thereby stopping an overgrowth of bad bacteria. 
  2. It produces an enzyme that breaks down pathogenic/bad bacteria such as C. difficile toxin A, and stimulates an antibody production against this diarrhea causing toxin. 
  3. It inhibits the main inflammation regulators by changing the signaling pathways involved in inflammatory intestinal diseases. 
  4. It acts on T cells which may interfere with the development of Inflammatory Bowel Disease (IBD). 
  5. It improves the fecal biostructure in patients with diarrhea.
Therefore by taking BoulardiiMAX the S. boulardii acts as a temporary flora to protect your intestinal tract and keep the intestines functioning well.
