Classic joint health support is on the way with 21st Century Glucosamine Chondroitin Complex Plus MSM. This formula takes a three- pronged approach to promoting healthy joints beginning with glucosamine. A natural compound found in cartilage, glucosamine supplementation has been associated with long-term preservation of connective tissues and with enhanced joint comfort. Additional support comes from chondroitin, a molecule found in cartilage which aids in the absorption of fluid into the joint's connective tissues for added comfort and mobility. It also delivers MSM (methylsulfonylmethane), a naturally occurring chemical largely comprised of sulphur, which is known to deliver antioxidant defense in addition to supporting healthy joint function.
