Thorne

Sacro-B

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.*

This product has been third-party tested and certified to verify what's in the package matches what's on the label and to confirm it contains no unsafe levels of contaminants, such as heavy metals, pesticides, and microorganisms.
