Nutritional Information

1. Supports Digestive Health: Saccharomyces boulardii is a beneficial probiotic that helps maintain a healthy balance of bacteria in the gut, promoting proper digestion and absorption of nutrients.
2. Boosts Immune System: By enhancing the production of antibodies, Saccharomyces boulardii can help strengthen the body's immune system and protect against infections.

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.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
