A yeast that mitigates occasional diarrhea and supports the growth of beneficial gut flora*

Sacro-B (Saccharomyces boulardii) is a yeast species that enhances immune function in the gut by increasing sIgA and is effective for antibiotic-associated diarrhea.*

In clinical studies, Saccharomyces boulardii has demonstrated its ability to increase the production of secretory IgA, the first-line defense immunoglobin of the gastrointestinal tract.* In addition to enhancing immune function in the gut, this yeast species also supports the growth of beneficial intestinal flora, and it can also be helpful for mitigating occasional diarrhea.* With a minimum of 5 billion CFUs per capsule, Thorne's Sacro-B provides substantial support to the health of the gastrointestinal tract.*
