Collagen pieces send messages to your cells to make more collagen, like a blueprint for repair.
Scientific Claim
Collagen peptides function as signaling molecules that activate gene expression pathways responsible for collagen synthesis and tissue remodeling.
Original Statement
“there was a study that found that collagen peptides act as signaling molecules. Okay? So they literally flip on genes that regulate the formation of new collagen tissue. In other words, your body doesn't use them as just plain old fuel. They're like instructions, okay? They're like a blueprint.”

This study looks at how a specific pathway in the body affects the production of collagen and other proteins in airway smooth muscle cells.
Stimulation of type II collagen biosynthesis and secretion in bovine chondrocytes cultured with degraded collagen
When collagen is broken down into smaller pieces, it sends a signal to cartilage cells to make more collagen — like a 'build more!' message — but whole collagen doesn't do this.
This study shows that collagen talks to cells through special receptors, and since collagen peptides are tiny pieces of collagen, they probably do the same thing—telling cells to make more collagen and repair tissues.
This study looks at how specific receptors on the surface of cells regulate the production of collagen, a key protein in the body's connective tissue.
Technical explanation
This paper directly studies the role of collagen receptors in regulating collagen gene expression in cardiac fibroblasts, which is closely related to the assertion.
