Collagen is the most abundant protein in the human body and a key constituent of skin, joints, bones, blood vessels, organs and more. The word “collagen” is derived from kolla, the Greek word for glue. Collagen is literally the substance that binds us together. It forms a mesh-like supportive framework in the body that provides shape, strength and flexibility. Highly prized for its nutritional and amino acid profile, collagen is uniquely abundant in glycine, proline and hydroxyproline. In fact, Collagen is the only known source of hydroxyproline, which is believed to help stimulate the body’s own production of collagen.*
