Jarrow Formulas Saccharomyces Boulardii + MOS (90 Veggie Caps)
by Jarrow Formulas
"5 billion CFU S. boulardii + MOS prebiotic — the antibiotic-resistant yeast probiotic for travel diarrhea and C. diff prevention with 22,000+ reviews"
Overview
Jarrow S. boulardii + MOS provides 5 billion CFU of Saccharomyces boulardii — a beneficial yeast (not bacteria) probiotic — combined with MOS (mannan-oligosaccharides) prebiotic from yeast cell wall. S. boulardii is unique among probiotics because it's a yeast, making it naturally resistant to antibiotics (which only kill bacteria). This makes it the ideal probiotic to take during antibiotic therapy to prevent antibiotic-associated diarrhea and C. difficile infection. S. boulardii also has strong evidence for preventing traveler's diarrhea. MOS acts as a prebiotic that binds to pathogenic bacteria (E. coli, Salmonella) and prevents them from adhering to the intestinal wall. The 90-capsule count provides a 3-month supply. Shelf-stable — no refrigeration required.
