The first U.S. multicenter study to investigate glucosamine and chondroitin, two dietary supplements widely marketed in the United States as effective natural remedies for osteoarthritis (OA), is about to begin. In September 1999, the National Center for Complementary and Alternative Medicine (NCCAM) in collaboration with the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) announced a contract award to the University of Utah to determine conclusively whether glucosamine or chondroitin are more effective than placebo for treating knee pain associated with OA.
