Collagen serves several essential functions in maintaining joint health. It is the most abundant protein in the body and provides structure and strength to connective tissues, including tendons, ligaments, and cartilage. Collagen supports joint stability and elasticity, thereby reducing the risk of injuries and degenerative conditions such as osteoarthritis. Additionally, collagen supplementation has been shown to improve joint pain and increase functional movement in physically active individuals and older adults. Ensuring adequate collagen intake, through diet or supplementation, can help maintain joint integrity and enhance overall mobility.
