Identity and form

Saccharomyces boulardii is a probiotic yeast; strain identity, viable count, storage, and immunocompromised-host context matter.

The label should identify the source, form, preparation, and active or marker amount when those details determine comparability.

What the evidence can answer

Human research has examined Saccharomyces boulardii in relation to microbiome composition and function, digestive function. The amount, source, preparation, population, comparator, and measured outcome determine whether a result applies to a finished product.

Current WQ evidence label: Limited human evidence. This label describes the present evidence context, not a promise of benefit.

Safety and decision context
