CondroArtil with UC-II collagen is a dietary supplement that, in addition to its main ingredient: undenatured type 2 collagen (UC-II®), also contains vitamins C, D3, K2, copper, and manganese. This combination of nutrients is designed to help maintain healthy bones1, 2 and to promote the formation and maintenance of connective tissue (supporting tissue)3, 4 and collagen1. Collagen is the most abundant protein in the body (25%) and is a fundamental component of connective tissues, such as skin, tendons and bone, where it performs a structural function providing support and resistance. Collagen is not a single protein; it is a family of closely related but genetically distinct molecules. Several types of collagen are described, each distinguished by the arrangement of its fibrils. There are up to 21 types of collagen in mammals, but the best known are types I, II, III, and IV. UC-II is an undenatured collagen. Unlike hydrolyzed collagens, UC-II® has a different and unique mechanism of action. It works through a process called oral tolerance, which involves the immune system and allows for the desired results to be achieved with a small dose of just 40 mg/day. CondroArtil is a complete formula for cartilage and joint care that includes: UC-II®, vitamins C (PureWay-C®), vitamin D3 and vitamin K2 (MenaQ7®), manganese and copper. Instructions for use 1 capsule daily or as recommended by an expert.
