Chondroitin, Glucosamine Studied


Chondroitin, Glucosamine Studied

BOSTON--By reviewing studies from the last 20 years, researchers at Boston University found that glucosamine and chondroitin sulfate may help treat osteoarthritis with few adverse effects. Published in the March 15 issue of The Journal of the American Medical Association (JAMA), of the 15 studies that met the researchers controls, only one had not been funded by the supplements' manufacturer. The National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) funded this study, and will launch a large clinical trial with the National Center for Complementary and Alternative Medicine (NCCAM) at the University of Utah. More than 1,000 patients are expected to be recruited later this year. For more information, visit

In related news, researchers at the University of Maryland found that glucosamine and chondroitin products overstated the amount of ingredients present in each capsule. Similar to the findings published by last month, these results were published in the April 11 issue of The Journal of the American Nutraceutical Association. In an analysis of 32 products, 26 were found to contain less than 90 percent of the labeled amount of chondroitin. Only five were found to have more than 90 percent. For information, visit
