I beg to differ with Bob that arthritis doesn't go away. I had arthritis so bad in my back that I cried every morning as I got dressed. It would take me 20 min to get my socks and pants on. I thought I would never hunt, fish, golf, and I didn't see how I could continue like this. I took every medication they had,with minimal results. Them a friend told me the results he had with glucosimine with his knee. So I gave it a try, and thought I noticed some improvement. About the same time I had a physical for my CDL(truck driver)and I ask my Doc about this, I expected him to say"snake oil,save your money),but no, he says"that's goods stuff" he aske how much I was taking and I told him 500mg, he said to bump it up to 1500mg. A few weeks later 99% arthitis is gone. Instead of missing 30 days or more because of my back, I have missed 0. This has been over 5 yrs now. I hunt,fish,golf, run, and now I shoot archery. If you are experiencing any arthritis and you don't at least give it a try your making a mistake. I have people to out of there way to find me and thank me for getting them to try it. I was close to getting surgery for my back as I have 4(one real bad)ruptured disc. I have had 0 days that I have been flat on my back since taking this. It's been a miracle in my life-maybe yours too.
