Ther-Biotic® Saccharomyces Boulardii: Resilient Probiotic Yeast Support*

Ther-Biotic® Saccharomyces Boulardii provides targeted support for gastrointestinal and immune health using a powerful, non-pathogenic, and beneficial yeast. S. boulardii is a hardy, acid-resistant microorganism that is not affected by antibacterial agents, making it a unique and effective probiotic. It has been clinically studied and shown to support healthy intestinal function, promote normal bowel transit time, and assist individuals with occasional diarrhea.*

How It Works: A Unique, Multi-Action Probiotic

This formula delivers a potent 3 billion CFU dose of a transient yeast that works in several ways to promote a healthy and balanced gut environment.*

Supporting a Healthy Gut and Immune Response
S. boulardii helps nourish colon mucosal cells and augments the intestinal absorption of D-glucose and sodium, which can enhance the uptake of water and electrolytes during occasional diarrhea. It also modulates immunity by boosting the intestine’s secretion of IgA and supports a healthy inflammatory response associated with digestive discomfort.*

Resilient and Effective
Unlike bacterial probiotics, S. boulardii is genetically and functionally distinct from brewer’s yeast and is not harmed by antibacterial agents, allowing it to provide consistent support. Its natural temperature tolerance and acid resistance ensure it arrives in the gut intact and ready to work.*

  • A powerful, unique, non-pathogenic yeast probiotic
  • Assists individuals with occasional diarrhea and supports normal bowel transit time*
  • Supports a healthy immune and inflammatory response in the gut*
  • Acid-resistant, temperature-tolerant, and unaffected by antibacterial agents
