Indications & Uses

Pharmacology

Saccharomyces boulardii survives stomach acid and settles in the intestinal tract, where it acts as a temporary flora and protects the beneficial organisms of the intestine. It also works with the body to re-establish the microflora, and this helps maintain and support healthy immunity, digestion and gut health. It shows the following actions. Anti-toxin activity: S. boulardii produces proteins that work to neutralize bacterial toxins, and this may include the toxins produced by Clostridium difficile. Anti-microbial: S. boulardii sticks to pathogens, so they attach less to the intestinal wall and invade enterocytes less. The pathogens are then removed during bowel movements. Enzymatic activity: in healthy adults, S. boulardii increases the enzymatic activities (lactase, alpha glucosidase, alkaline phosphatase). Its production of intestinal polyamines is one of its most relevant and specific mechanisms of action. The polyamines spermidine, spermine and putrescine boost the expression of brush border enzymes (such as hydrolases, proteases and transport molecules). Immune enhancement: S. boulardii helps prevent infection by stimulating the immune system along the GI lining, and it does this by increasing the protective antibody IgA. Anti-inflammatory: S. boulardii causes a decrease in pro-inflammatory cytokines.
