Collagen tells your body to fix tendons and cartilage, but regular amino acids don't do that.
Scientific Claim
Collagen peptides specifically stimulate cellular repair mechanisms in ligaments, cartilage, and soft tissues, which is not observed with standard amino acid mixtures.
Original Statement
“there was another study that showed that collagen peptides stimulate repair signals specifically for ligaments, for cartilage, and for other soft tissue. That does not happen with like a generic amino acid blend. It's about the signaling.”

Evidence from Studies
Supporting (3)
This study found that taking collagen peptides orally can help improve wound healing after surgery in rats.
Collagen Mimetic Peptides Promote Repair of MMP-1-Damaged Collagen in the Rodent Sclera and Optic Nerve Head
This study shows that special peptides can help fix damaged collagen in tissues, which is important for healing.
Contradicting (2)
Collagen scaffold supplementation does not improve the functional properties of the repaired anterior cruciate ligament
This study shows that adding collagen to repair a ligament doesn't make it heal better.
This study finds that a combination of therapies can help heal wounds in diabetics, but doesn't specifically look at collagen peptides.
