Overview

Jarrow S. boulardii + MOS provides 5 billion CFU of Saccharomyces boulardii CNCM I-745 with mannan-oligosaccharides (MOS) per capsule. S. boulardii is a beneficial yeast (not a bacteria) that is naturally resistant to antibiotics — making it the only probiotic that can be taken concurrently with antibiotic therapy without being killed. MOS (derived from yeast cell walls) acts as a prebiotic decoy that binds to pathogenic bacteria (E. coli, Salmonella), preventing them from attaching to intestinal walls. The 180-capsule count provides a 6-month supply. Room-temperature stable.
