Overview

S. boulardii is a unique probiotic yeast (not bacteria) that is naturally resistant to antibiotics—making it the ideal probiotic to take during antibiotic treatment. Jarrow adds MOS (mannan-oligosaccharides) which bind to pathogenic bacteria, preventing them from attaching to the gut wall.
