Iron and Iron for Fatigue with low ferritin (non-anemic)
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
Iron
Only supplement it against a ferritin number — transformative in deficiency, pro-oxidant and constipating in excess.
Grade A3 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.

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.
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.
