The first ever large scale clinical trial on the effects of Glucosamine and Chondroitin, conducted by the US government has now finished the first phase results. This multi-centre clinical trial was conducted after the controversy in medical literature on how effective Glucosamine and Chondroitin were at treating osteoarthritis.
The US government help to fund the trial, that’s purpose was to see how effective Glucosamine and Chondroitin were at treating knee osteoarthritis, either taken together or separately. The first phase of this trial which was coordinated by the University of Utah School of medicine, and situated across 16 different rheumatology research centres across the united States, has shown positive results.
The National Centre for Complementary and Alternative Medicine (NCCAM) and the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) funded the Glucosamine Arthritis Intervention Trial (GAIT).
This $12.5 million trial was a double blind trial, which means that neither the participants nor researchers knew which treatment group they were in or researching. This way of conducting the trial was the most appropriate way to try and gain unbiased results.
