I take that too, I don't know if it does anything as when I started taking it I didn't have any pain but I give the same pills to the dog who has arthritis in her legs and the difference after 4 weeks is amazing. I do know that it is one of those cumulative supplements in that you have to wait 2-6 weeks for it's effect and you have to keep up with it. I think I'm becoming a walking labratory.
