Collagen Peptides (+ Vitamin C)

Evidence: ★★★★☆ · Status: OTC Supplement

In plain English

Feeds your tendons and ligaments their raw materials right before you stress them — timing matters, so take it ~45 min before training with vitamin C.

How it works

Hydrolysed collagen supplies glycine/proline/hydroxyproline that preferentially accumulate in tendon/ligament; taken with vitamin C (cofactor for prolyl hydroxylase) before loading, it doubles collagen-synthesis markers.

Molecular target & official sources

COL1A1 collagen type I (NCBI Gene) · P4HA1 prolyl hydroxylase (NCBI Gene)

Protocol

15 g + 50 mg vitamin C, 45–60 min pre-exercise.

Bottom line

The most practical connective-tissue supplement; timing is key. Highly relevant to running/Hyrox tendon load.

Helps with: Joint Health · Stress & Anxiety · Skin & Hair

Stacks with

Vitamin C — required to build collagen, so take them together, ideally 45–60 min before training tendons.
