I have used several with Glucosamine and Chondroitin. They seem to work well over time. But that's the thing. According to everyone I spoke with before starting, you have to take them for several weeks to really get the full effects of the supplement. And they were right. You can't just pop a coupe when you feel achy. You pretty much add it as a daily supplement. When I slack off and forget to take it for a while, I do notice more stiffness, but I always get back on track before it turns to pain.
