The Active Ingredient Is: Saccharomyces boulardii

Saccharomyces boulardii is a friendly, non-pathogenic yeast used as a probiotic to support digestive function and immune balance. The powder form provides the active probiotic ingredient for everyday use within hypoallergenic, lactose-free and gluten-free preparations.

This form is supplied as a probiotic yeast focused on gut and immune health, usually produced under GMP standards with a vegetarian capsule matrix; the powder version fits this single-ingredient profile.

What Saccharomyces boulardii Does?

Dr. McFarland from the University of Calgary found that Saccharomyces boulardii supports normal gut function and gut-immune balance, contributing to mucosal defence and barrier integrity as part of EFSA-aligned understanding of probiotic roles.

This probiotic yeast helps reduce the incidence of antibiotic-associated and traveller’s diarrhoea in clinical contexts, and it has been studied for its role in supporting digestive comfort and normal bowel transit within gut health research.
