Inositol (Myo-Inositol) and Berberine
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.
Compound or practice
Inositol (Myo-Inositol)
A sugar-alcohol with genuinely good evidence in PCOS and reasonable anxiety/OCD signals.
Grade B3 graded outcomesrevised Jul 10, 2026
A structured monograph in Prometheus's bundled library. Its grades are the monograph's own reading of the evidence, not a peer-reviewed review.
Compound or practice
Berberine
A plant alkaloid that behaves like a metabolic drug — real glucose and lipid effects, and it deserves drug-level caution.
Grade B2 graded outcomesrevised Jul 10, 2026
A structured monograph in Prometheus's bundled library. Its grades are the monograph's own reading of the evidence, not a peer-reviewed review.

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.
