What is UC-II Collagen?
UC-II is the abbreviation of “Undenatured Type II Collagen”, which is usually derived from chicken breast cartilage and is a high-end raw material for joint health in dietary supplements.
Unlike ordinary hydrolyzed collagen, UC-II retains the natural triple helix structure, so it has an immunomodulatory effect in the body, which can help reduce joint inflammation and relieve joint pain.
