Four Leaf S. Boulardii

Yeast-based probiotics are unique because they are not harmed by antibiotics, like other probiotics are. Studies also show that Saccharomyces boulardii can help ease digestive upset during antibiotic use.

This friendly yeast delivers other gut benefits too. It helps maintain a healthy gut lining and studies show S. boulardii can influence parts of the immune system that maintain proper gut permeability.
