Overview

Jarrow S. boulardii + MOS 180ct provides 5 billion CFU of Saccharomyces boulardii per capsule with MOS (mannan-oligosaccharides) prebiotic. This is the value-size version of Jarrow's popular yeast probiotic, providing a 6-month supply. S. boulardii is a beneficial yeast (not a bacteria) that is naturally resistant to antibiotics — making it the only probiotic that can be taken simultaneously with antibiotics without being killed. It's the most researched probiotic for C. difficile prevention, traveler's diarrhea, and antibiotic-associated diarrhea. MOS is a prebiotic derived from yeast cell walls that binds to pathogenic bacteria (E. coli, Salmonella) and prevents them from adhering to the intestinal wall.
