AOR Saccharomyces Boulardii contains 250mg of the beneficial, non-pathogenic, non-colonizing species of yeast.


It is clinically recognized for its effectiveness in contending with the symptoms of antibiotic-associated diarrhea (AAD) and Clostridium difficile disease (CDD), which is also incited by antibiotics. CDD is a leading cause of nosocomial outbreaks of diarrhea and colitis, and Saccharomyces boulardii is one of the most widely used and highly regarded probiotics for the treatment of symptoms associated with both AAD and CDD.

While the precise mechanism of action for S. boulardii remains the subject of conjecture, there are three basic types of explanations – or a combination thereof. The first involves the ability of S. boulardii to prevent the gastrointestinal inflammation that causes diarrhea by interfering with the various pathogens that bind to gastrointestinal cells. The second is based on S. boulardii providing an enhancing effect for certain protective proteins of the immune system whose role is to protect the body from such pathogens. One particular pharmacokinetic theory closely related to this explanation is that S. boulardii secretes a protease that digests two protein exotoxins which are themselves mediators of inflammatory diarrhea and colitis. The third explanation is that S. boulardii actually competes with pathogens for receptor sites on the cells of the intestinal walls.
