It’s non-pathogenic and, unlike other yeasts, it grows at a high temperature, up to 37 degrees Celsius. S. boulardii is also hypoallergenic. Saccharomyces boulardii is particularly effective as a digestive tract micro-organisms since it is able to survive stomach acid and colonize the intestinal tract, where its benefits are fully realized.
