Overview
Absorbed as di/tripeptides that stimulate collagen-producing cells (fibroblasts, chondrocytes, osteoblasts).
Proposed mechanism
Hydrolyzed collagen provides amino acids (proline, glycine, hydroxyproline) that stimulate fibroblast activity and extracellular matrix synthesis.
What the evidence supports
Human data exists but the trials are small, short-term, or not yet replicated.
Graded Human-limited
Human data that exists but is thin: open-label work, single-arm studies, small cohorts, or observational follow-up without randomisation.
