Saccharomyces boulardii is a nonpathogenic, transient yeast long used to support normal bowel transit time.† It is a hardy, acid-resistant, temperature tolerant microorganism that is not affected by antibacterial agents. S. boulardii is genetically and functionally distinct from brewer’s yeast (S. cerevisiae) and different from pathogenic Candida species.

S. boulardii May increase the activities of intestinal brush border enzymes such as disaccharidases, α-glucosidases, alkaline phosphatases, and aminopeptidases.†

S. boulardii may augment the intestinal absorption of D-glucose coupled with sodium that may enhance uptake of water and electrolytes during occasional diarrhea.† It may increases stool concentrations of short-chain fatty acids that nourish colon mucosal cells.† S. boulardii may modulate immunity by boosting intestinal secretion of IgA and increasing crypt cell immunoglobulin receptors.† It may support healthy inflammatory response.†
