In clinical studies, Saccharomyces boulardii has demonstrated its ability to increase the production of secretory IgA, the first-line defence immunoglobulin 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 diarrhoea. With a minimum of 5 billion CFUs per capsule, Thorne's Sacro-B provides substantial support to the health of the gastrointestinal tract.
