Collagen tells your body to fix tendons and cartilage, but regular amino acids don't do that.

Oral administration of marine collagen peptides prepared from chum salmon (Oncorhynchus keta) improves wound healing following cesarean section in rats

Randomized Controlled Trial

Animal

2015

This study found that taking collagen peptides orally can help improve wound healing after surgery in rats.

Stimulation of type II collagen biosynthesis and secretion in bovine chondrocytes cultured with degraded collagen

Cross-Sectional Study

Animal

2003 Mar

This study found that broken-down collagen (peptides) makes cartilage cells produce more of their own collagen, but regular protein mixtures don’t do the same—so collagen peptides are special for repair.

Collagen Mimetic Peptides Promote Repair of MMP-1-Damaged Collagen in the Rodent Sclera and Optic Nerve Head

Cohort Study

Animal

2023 Dec 1

This study shows that special peptides can help fix damaged collagen in tissues, which is important for healing.

Collagen scaffold supplementation does not improve the functional properties of the repaired anterior cruciate ligament

Randomized Controlled Trial

Animal

2010 Jun

This study shows that adding collagen to repair a ligament doesn't make it heal better.

Similar Assertions

Collagen peptides specifically stimulate cellular repair signaling pathways in ligaments, cartilage, and other soft tissues, a response not elicited by non-collagenous amino acid blends.

97%

Collagen peptides function as signaling molecules that activate gene expression pathways responsible for collagen synthesis and tissue remodeling.

78%

Collagen-derived peptides function as bioactive signaling molecules that upregulate gene expression involved in de novo collagen synthesis and tissue remodeling.
