Why change a winning team?

Yet another report suggests that glucosamine and chondroitin don't have any effect on painful knees and hips. Well all I can say is that I used to have big problems with my right leg - specifically knee and hip pain, and I've now been taking G&C tablets for about ten years, and the problem has disappeared. Maybe just a coincidence, but I'm not risking a return to the bad old days, and will continue "taking the tablets".
