With the help of fibronectin, Type II Collagen is able to aid the binding process in the joints. It also supports the cartilage and contributes to its elasticity and strength. Type II Collagen is solely responsible for providing collagen that forms the cartilage, as opposed to Type I Collagen, which provides the body with amino acids and protein. When taken orally as a supplement Type II Collagen can result in lowered joint inflammation that is associated with rheumatism and osteoporosis. It also reduces the autoimmunity of the body's natural Type II Collagen.
