Trikem's Collagen contains collagen, hyaluronic acid, and MSM. Collagen is a protein that is one of the building blocks of tendons and ligaments. Hyaluronic acid is naturally found in joint fluid, where it acts as a shock absorber and supplies the various parts of the joint complex with nutrients. MSM is involved in the production of new cells and helps in the formation of collagen and keratin. Trikem's Collagen is suitable for use during rehabilitation after a joint, tendon, or ligament injury.
