Glucosamine and chondroitin supplements don't work

In a review of trials involving 3,803 patients with knee or hip osteoarthritis, Swiss researchers found there was 'no clinically relevant effect' of chondroitin, glucosamine, or the two in combination on perceived joint pain.

'Health authorities and health insurers should not cover the costs for these preparations, and new prescriptions to patients who have not received treatment should be discouraged,' said Peter Juni of the University of Bern, whose study was published in the British Medical Journal on Friday. MORE
