UC-II® native undenatured collagen type II in combination with rosehip and devil's claw. Collagen – the building material of articular cartilage The articular surfaces are surrounded by a layer of cartilage. Although this is only a few millimeters thick, it is essential for a pain-free functioning joint. The elastic collagen fibers form the framework of the cartilage - and are a prerequisite for its elasticity and high compressive strength. The cartilage counteracts the friction between the bones and acts as a natural shock absorber. There are 28 types of collagen in the body. The two most important are type I and type II. While collagen type I is mainly found in the skin, collagen type II makes up the majority of the collagens found in joints - more precisely: in articular cartilage.
