I have arthritis in my back and hips and have pain when doing anything. This supplement has helped reduce my pain considerably!

The product works effectively and I'm glad I bought the bottle. However, the advertisement is a bit misleading. I wanted to buy it for my parents but it turned out that the product was for men only. I didn't knew this fact until I got the product, which was a bit late.

After a month or so the pain and stiffness in my knees is gone. Great product and recommend it highly.

I have been using UC II for about a month and it is working. When I came back to order more, I saw t u is M Drive, so thought I'd try it. The first pill I took caused my asthma to flare up horribly. I could've breathe or sleep all night. I thought it may just be the weather. So I felt better as the 2nd day went on and I took a wnd pill the 2nd night, and once again I had horrible asthmatic issues. So, the 3rd night, I didn't take it and went back to my UCII instead and I was fine. Not sure which ingredient got me. Wish I knew. I was so disappointed that I could not take this for my knee pain.

I was a runner all my life then had a knee injury. Started taking Swanson's Collagen II and it made a huge difference. I tried this brand because it was less expensive than Swanson's. It did not work for me at all. I can notice a big difference in the negative and will return to my old brand or try Costco's brand next time.<br /><br />UPDATE: I received an email from them promising a refund. They followed through without any trouble. Thank you for keeping your promise! It's rare today, so MUCH appreciated. Because of this, I'll take a look at other products from your company. Perhaps there will be other products that work for me.

The Mdrive works better than Glucosamine for me. It relieves the Joint pain plus make mobility of the joint a bit more fluid. If you've tried various brands and not satisfied with the results its worth a shot.
