Collagen has special amino acids that your body uses to build and fix things like cartilage, tendons, and skin.
Scientific Claim
Glycine, proline, hydroxyproline, and arginine are critical structural components required for the synthesis and maintenance of connective tissues including cartilage, tendons, ligaments, fascia, and skin.
Original Statement
“Collagen brings glycine, it brings proline, it brings hydroxyproline, it brings something called arginine. These are raw materials that your connective tissue and the raw materials that your connective tissue, your cartilage, your tendons, your ligaments, your fascia, and even your skin really do rely on.”

The Molecular Interaction of Collagen with Cell Receptors for Biological Function
This study found that kids with connective tissue problems have different levels of certain amino acids in their urine, which could help diagnose and understand these conditions.
This study looks at how certain amino acids are made in the bodies of young pigs and how it might affect their growth.

This study looked at how L-arginine affects cartilage health in rats with a certain condition, and found it to be beneficial.
