Beta-Carotene for Vitamin-A status and Beta-Carotene
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.

Evidence grade B — Corrects deficiency
Grade B1 graded outcomerevised 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
Beta-Carotene
A provitamin-A carotenoid that's healthy from food but became the cautionary tale of supplements — high doses raised lung-cancer risk in smokers.
Grade C2 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.

Both columns are read from the entries as they stand in this library. A comparison is not advice to take either one, and it is no substitute for a clinician who knows the person.
