The evidence in words
The verdict
For osteoarthritis, Collagen Peptides earns evidence grade B (unclear effect, mixed consistency) — there is real evidence here. Pain/function
How it might work
Peptides may signal fibroblasts to increase collagen synthesis and supply substrate; the vitamin-C cofactor is required for the hydroxylation steps that stabilize collagen.
How to use it
10–15 g collagen peptides with ~50 mg vitamin C, ideally 30–60 minutes before training or rehab loading.
Safety & cautions
Very safe; it is food-grade protein. It is not a complete protein, so it doesn't count toward muscle-building protein targets.
Bottom line
One of the better connective-tissue supplements: 15 g with vitamin C before you load the joint or tendon. Modest, real, low-risk.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
- Standard
- 10–15 g with 50 mg vitamin C, 30–60 min pre-load.
