Millions of Americans with knee pain have tried supplements like Glucosamine or Chondroitin thinking they help protect cartilage and ease the pain. And now, one of the largest studies brings mixed reviews. Researchers at the University of Arizona say overall, the supplements don't help much, but when it comes to treating severe knee pain, Glucosamine and Chondroitin brought significant relief.
"A full 79 percent of those patients had significant pain relief. This was actually better than the prescription drug in the study," said Jason Theodosakis, M.D., preventive medicine. However, researchers say the government doesn't regulate supplements, so, consumers should be realistic and understand that there isn't one remedy that works for every knee.
The study is published in the new England Journal of Medicine. The randomized, placebo- and celecoxib-controlled trial included more than 1200 people who took 1500 mg of Glucosamine Hydrochloride daily, 1200 mg of Chondroitin Sulfate, or the two in combination. The study was funded by the National Center for Complementary and Alternative Medicine and the National Institute of Arthritis and Musculoskeletal and Skin Diseases.
