Overview

Jarrow Formulas S. Boulardii + MOS provides 5 billion CFU of Saccharomyces boulardii (a beneficial yeast, not bacteria) combined with MOS (mannan-oligosaccharides) prebiotic from yeast cell wall. S. boulardii is the most studied probiotic for antibiotic-associated diarrhea and traveler's diarrhea, with over 50 clinical trials. Unlike bacterial probiotics, S. boulardii is naturally resistant to stomach acid and antibiotics, making it the ideal probiotic to take alongside antibiotic therapy. The 90-capsule count provides a 3-month supply.
