The Active Ingredient Is: Saccharomyces boulardii

Saccharomyces boulardii is a probiotic yeast used to support digestive health and a balanced gut flora. It helps maintain normal gastrointestinal function during disturbances such as disruption or antibiotic use.

This probiotic is provided in a capsule form as a live microbe intended to contribute to gut health. It supports the gut environment and, alongside other ingredients in the product, helps support overall digestive well-being.

What Does Saccharomyces boulardii Do?

Dr. Ciorba of Mayo Clinic found that Saccharomyces boulardii can reduce the incidence and recurrence of antibiotic-associated and traveler’s diarrhea, indicating a role in supporting gut balance during GI stress.

In addition, this probiotic species resists stomach acid, competes with potential pathogens, and helps maintain the gut barrier, contributing to normal digestive function and microbial harmony.
