Support your digestive balance with Jarrow Formulas Saccharomyces Boulardii + MOS Probiotics, a clinically researched probiotic yeast formula designed to help maintain healthy intestinal flora, digestive comfort and gut resilience.
Key Health Benefits
Digestive Defense & Balance: Helps restore normal intestinal flora when disrupted by poor diet, antibiotic use, or travel.
Diarrhea Management: It helps to reduce the duration and severity of traveler’s diarrhea and antibiotic-associated diarrhea.
Prebiotic Action: The added MOS (MannanOligoSaccharide) acts as a prebiotic decoy, binding to unfriendly bacteria and sweeping them out of the gut while simultaneously feeding beneficial flora.
Stomach Acid Resistance: Unlike standard bacterial probiotics, this beneficial yeast naturally survives stomach acid to effectively colonize the intestinal tract.
