Collagen is described as the building blocks of the skin. It therefore has a key role to play in creating and maintaining healthy skin all over the body. It has, however, been scientifically shown that it diminishes at a rate of approximately 1.5% per annum from the age of 25 years onwards. Collagen is the most abundant structural protein found in cartilage, muscle, tendons, ligaments and bones. Collagen protects cartilage and synovial fluid against deterioration and is the raw material for cartilage synthesis and repair. It can also reduce oxidative damage to joints and therefore stimulate significant reductions in joint pain, tenderness and swelling.
