Collagen is composed of the amino acids glycine, proline, and hydroxyproline and is the most abundant protein in the body. Collagen provides structure and support to many tissues, including bones, tendons, ligaments, and skin, and is essential for maintaining healthy connective tissue. The intense demands of training can subject the body to significant stress and increase the risk of injuries. Supplementing with collagen can help strengthen and repair tissues and, in turn, improve overall performance and recovery.
