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 increases the activities of intestinal brush border enzymes such as disaccharidases, α-glucosidases, alkaline phosphatases, and aminopeptidases.

S. boulardii augments the intestinal absorption of D-glucose coupled with sodium that may enhance uptake of water and electrolytes during occasional diarrhea. It increases stool concentrations of short-chain fatty acids that nourish colon mucosal cells. S. boulardii modulates immunity by boosting intestinal secretion of IgA and increasing crypt cell immunoglobulin receptors. It supports healthy inflammatory response, where inflammation is associated with occasional digestive discomfort.^† Research has found that S. boulardii supports healthy intestinal function in an array of clinical settings, supporting healthy bowel transit time.
