Collagen protein

Collagen protein

Collagen protein is a complex structural protein that maintains the strength and flexibility of skin, ligaments, joints, bones, muscles, tendons, blood vessels, gums, eyes, nails, and hair. It's the most abundant protein in mammals, making up from 25% to 35% of the whole-body protein content. Collagen comes in at least 16 types, but the vast majority of collagen in the body is type I, II, or III. All collagen molecules are composed of three polypeptide chains arranged in a triple helix, with each chain being over 1,400 amino acids long.

Molecular Formula

Not applicable for complex proteins

Mechanism of Action

Supplemental collagen is hydrolyzed, or broken down, into peptides for better absorption. These peptides can be absorbed into the bloodstream and distributed to the skin, joints, and bones where they act as building blocks, triggering our own internal collagen production.
