Quick Summary
Oral collagen supplementation — skin elasticity, joint health, and hair thickness
Also called: Hydrolyzed Collagen, Collagen Supplement, Type I Collagen, Marine Collagen
What is Collagen Peptides?
Hydrolyzed collagen peptides are short-chain amino acid sequences (primarily glycine, proline, hydroxyproline) derived from bovine, porcine, or marine sources. When ingested, they are absorbed as dipeptides and tripeptides that stimulate fibroblast activity in the dermis, increasing endogenous collagen and elastin production. Multiple RCTs demonstrate improvements in skin elasticity, hydration, and wrinkle depth with 2.5–10g daily supplementation over 8–12 weeks (Proksch et al., 2014; Asserin et al., 2015). Marine collagen has superior bioavailability.
How It's Made
Produced by enzymatic hydrolysis of collagen from animal hides, bones, or fish scales. Hydrolysis breaks collagen into small peptides (2–5 kDa) with high bioavailability.
