The Active Ingredient Is: Saccharomyces boulardii

Saccharomyces boulardii is a probiotic yeast used to support gut microbial balance and normal digestive function. This ingredient appears in probiotic formulas to help maintain resilience in the gut during changes in diet and environment.

This product includes a shelf-stable, vegan and non-GMO presentation with clear strain identification, which supports reliable delivery of this active culture as part of a probiotic blend.

What Does Saccharomyces boulardii Do?

Scientific evidence indicates that Saccharomyces boulardii can help reduce traveller’s diarrhoea risk and support digestive balance during periods of dietary change or gastrointestinal stress, as reported by Dr. Kollaritsch of the University of Vienna. This mechanism involves increasing the population of beneficial microbes and strengthening the gut’s natural barriers.

These actions align with EFSA and NHS-style principles for normal gut function, emphasising probiotic support for healthy digestion and microbial balance.
