Pure Saccharomyces Boulardii
Pure Saccharomyces Boulardii
60 Capsules Unflavored Capsules
Most probiotics struggle to make it through stomach acid and get to where they are needed in the GI tract. Even fewer can resist antibiotics. Our Pure S. Boulardii CNCM I-3799 strain, backed by Lesaffre's 170 years of expertise, resists both stomach acid & antibiotics to deliver microbiome protection where other probiotics fail.† This shelf-stable, hypoallergenic formula is extensively 3rd party tested in the USA, making it the gold standard.

What Makes Us Different
Most supplement companies cut corners where you can't see - using overseas manufacturing, skipping independent testing and loading products with gut-irritating fillers. We take the harder, more expensive path because your gut health deserves better than “industry-standard”.
Made & Tested
In The USA
While most L-Glutamine is made in China, where quality standards can vary, Gut L-Glutamine is proudly made, packaged & tested right here in the USA from start to finish. Quality you can trust.

United StatesS.Boulardii did the trick!
After 4 years of diarrhea; all the docs, diagnostic tests, FODMAP - no change, until I listened to a ZOE podcast episode, an interview with gastro doc Will Bukowski, who said s. Boulardii and partially hydrolyzed guar gum had “shown promising results in clinical trials”. I ordered some on Amazon, and improved immediately!! It was the only tool I’d found that worked. Now I take it twice daily -that, plus following a diet personalized for my microbiome (Zoe membership & testing) and I have healed my gut! So do I ‘enjoy’ good health? You bet I do!!
United StatesIt just works
