Now - Saccharomyces Boulardii - Probiotic 5 Billion CFU

NOW® Saccharomyces Boulardii 5 Billion CFU – Clinically Tested Probiotic Yeast for Gastrointestinal Support

Support gut microflora balance, digestive resilience, and healthy intestinal barrier function with NOW® Saccharomyces Boulardii. Unlike standard bacterial probiotics (such as Lactobacillus or Bifidobacterium), Saccharomyces boulardii is a hardy, non-pathogenic, probiotic yeast specifically adapted to survive stomach acid and bile salts intact to reach the intestinal tract where it is needed most.

Because it is a yeast rather than a bacterium, S. boulardii is unaffected by antibiotics, making it the premier choice for maintaining bowel regularity and gut integrity during medical treatments, occasional traveler's diarrhea, or seasonal gut distress.

Key Benefits

• Antibiotic-Resistant Support: As a beneficial yeast strain, it naturally survives antibiotic regimens, helping protect intestinal flora and prevent treatment-associated bowel disruptions.

• Soothes Occasional Diarrhea: Clinically studied to reduce the frequency and duration of occasional diarrhea, including traveler’s diarrhea and sudden digestive upsets.

• Strengthens Gut Barrier: Promotes the production of secretory Immunoglobulin A (sIgA)—the primary defense antibody lining the mucosal walls of your gut.

• Balances Microbiome Ecology: Inhibits opportunistic pathogens from adhering to the intestinal lining, encouraging a healthy, balanced microbial ecosystem.

• Survives Stomach Acid: Exceptionally heat- and acid-tolerant, ensuring viable colonization without requiring chemical enteric coatings.

Take 1 to 2 capsules 2 to 3 times daily between meals as needed, or as directed by your healthcare practitioner.
