Everything on this page is copied from public ClinicalTrials.gov registry records — it is not written from memory, and nothing here describes how Saccharomyces boulardii works or whether it is effective. Each trial links to its own record so you can check it yourself.
This page is built automatically: a daily sync job reads the registry records behind our country trial registers, collects every trial that lists Saccharomyces boulardii (or a registered synonym) as a drug or biological intervention, and tabulates the registry fields directly. Placebos and generic comparators are excluded. There is no AI drafting and no per-compound editorial pass, and the page has not been clinically reviewed. The “last verified” date above is the timestamp of that sync, not a review date. Our general editorial approach is described in our editorial standards and corrections policy. The ClinicalTrials.gov data on this page was last retrieved on 24 Sep 2026.
