Collagen Peptides: Joint Support and Skin Health
Collagen is the most abundant protein in the human body. Hydrolyzed collagen peptides have been the subject of growing research interest. Here's an evidence-based overview.

“Collagen constitutes roughly 30% of total body protein — making it the body's structural backbone at the molecular level.”
Collagen constitutes roughly 30% of the body's total protein content and is the primary structural protein of connective tissues — cartilage, tendons, ligaments, skin, and bone. Collagen production naturally declines with age, which has driven interest in dietary collagen supplementation.
Types I and III
Collagen exists in numerous forms (at least 28 identified types). Type I is the most abundant in the body and is found in skin, tendons, and bone. Type III is found alongside Type I in skin and blood vessels. Hydrolyzed bovine collagen peptides typically provide primarily Type I and III.
Hydrolyzation and absorption
Native collagen molecules are too large to be absorbed intact. Hydrolyzed collagen (also called collagen peptides or collagen hydrolysate) is broken into smaller peptide chains through enzymatic processing, which improves absorption. Research has shown that orally ingested collagen peptides are absorbed and accumulate in skin and cartilage tissue.
Research findings
Studies on collagen peptides have explored effects on:
Limitations to note
Research quality varies. Many studies are funded by supplement manufacturers. The field would benefit from more large, independent randomized controlled trials.
