Probiotics are well-known for their benefit on gut health. Most of them described in human health applications are bacteria strains but saccharomyces cerevisiae var. boulardii (S.boulardii) yeast has been demonstrated to have probiotic activities with modes of action that are differentiating from other widely used probiotics.
S.boulardii is the most documented probiotic yeast with more than 50 years of clinical research that supports the gut barrier defense system. It is very resistance to the gastric environment and can be used with antibiotic treatment and help to help balance the microbiome.
