I tried this originally with some borrowed from my father to help with a bit of tendinitis in my mouse clicker (index) finger. This stuff seemed to help substantially and I've tried other Glucosamine Chondroitin that was really cheap and completely ineffective. The cheap stuff didn't seem to help at all. The tablets seem to not digest well or something compared to the capsules. Regardless, I'm a fan now, and buy a few of these a year!
