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.

An essential antioxidant and enzyme cofactor — cures scurvy, modestly shortens colds, and triples plant-iron absorption.

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.

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.
