Collagen (Hydrolyzed Peptides)

Proteinoral · inferred

Hydrolyzed collagen peptides support skin elasticity, joint health, and bone density. Absorbed as di- and tripeptides (e.g., hydroxyproline-proline).

  1. Oral supplementation of specific collagen peptides has beneficial effects on human skin physiology: a double-blind, placebo-controlled study Proksch E et al. · Skin Pharmacology and Physiology, 2014 DOI

    RCT found 2.5-5g/day of collagen peptides for 8 weeks significantly improved skin elasticity by 7%, with effects persisting 4 weeks after supplementation ended.

  2. 24-Week study on the use of collagen hydrolysate as a dietary supplement in athletes with activity-related joint pain Clark KL et al. · Current Medical Research and Opinion, 2008 DOI

    RCT in 147 athletes found 10g/day collagen hydrolysate for 24 weeks significantly reduced activity-related joint pain compared to placebo.
