Jarrow Formulas Saccharomyces Boulardii + MOS (90 Capsules)
by Jarrow Formulas
"5 billion CFU S. boulardii + MOS in a 90-count value size — the antibiotic-resistant probiotic yeast with 18,000+ reviews"
Overview
Jarrow Formulas S. boulardii + MOS (90ct) provides 5 billion CFU of Saccharomyces boulardii per capsule with mannan-oligosaccharides (MOS) from yeast cell wall. S. boulardii is a probiotic yeast — not a bacteria — which means it is naturally resistant to all antibiotics and can be taken alongside antibiotic therapy without being killed. MOS acts as a prebiotic decoy that binds to pathogenic bacteria (E. coli, Salmonella) and prevents them from adhering to the intestinal wall. This 90-capsule value size provides a 3-month supply. The product is shelf-stable and does not require refrigeration.
