Vitamin C and Vitamin C for Cancer / CVD prevention
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
Vitamin C
An essential antioxidant and enzyme cofactor — cures scurvy, modestly shortens colds, and triples plant-iron absorption.
Grade A4 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.
