Supplements for gut health and Saccharomyces Boulardii
Each entry’s own grades, side by side. A grade says how strong the evidence is for one outcome — it does not rank one entry over the other.

24 compounds relevant to gut health, ranked by overall evidence grade.
Grade A24 graded outcomesrevised Jul 10, 2026

Compound or practice

A probiotic yeast with the best evidence for preventing antibiotic-associated and traveler's diarrhea.

A structured monograph in Prometheus's bundled library. Its grades are the monograph's own reading of the evidence, not a peer-reviewed review.
Graded in both
Outcomes are matched by name. Two entries can describe the same outcome in different words, so one listed further down may still be graded in the other.
No outcome has the same name in both entries. They may still overlap under different wording — read the two lists below.
