Collagen Peptides for Tendon / ligament and Collagen Peptides
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 C — With vitamin C, pre-load
Grade C1 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
Collagen Peptides
Real, if modest, evidence for tendon, joint, and skin outcomes when taken with vitamin C before loading — better than its hype suggested a decade ago.
Grade B3 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.
