Supplements for blood-sugar control 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.
Goal guide
Supplements for blood-sugar control
22 compounds relevant to blood-sugar control, ranked by overall evidence grade.
Grade A22 graded outcomesrevised Jul 10, 2026
Assembled by the app from other entries in this library. It adds no evidence of its own — follow the links to the entries it draws on.
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.
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.
