This supplement contains Glucosamine and Chondroitin, which may support joints in order to promote healthy cartilage and tissue, while MSM supports healthy collagen for supreme joint support. Joint Support is great to help with painful stiffness, discomfort, and poor range of motion. With a specialised Glucosamine Chondroitin complex per serving, you can move easily and comfortably again. Chondroitin is the most abundant glycosaminoglycan in cartilage and is partly responsible for the resiliency of cartilage. Chondroitin is also important in preventing the action of enzymes that can destroy cartilage.
