Collagen provides special building blocks that your tendons, skin, and joints need to stay strong and repair themselves.

Stimulation of type II collagen biosynthesis and secretion in bovine chondrocytes cultured with degraded collagen
When scientists fed cartilage cells broken-down collagen, the cells made more of their own collagen — meaning the pieces from the broken-down collagen helped the cells build new tissue.
The study shows that a powder made from collagen helps skin cells make more of the structural stuff (like collagen and other proteins) that keeps skin firm and healthy.
When cartilage cells didn’t get enough glycine, they couldn’t make enough collagen — proving glycine is a must-have building block for healthy joints and cartilage.

This study talks about how collagen talks to cells, not about how its building blocks become new body tissues.
This study says eating collagen supplements won’t make your skin or joints produce more collagen — because your body breaks them down too much to use them as building blocks.
