When I was young, I was diagnosed with juvenile arthritis. I suffered from pain in my joints for my entire life, especially in my hands, knees, and hips. I have been taking the Osteo Bi-Flex pills for my arthritis for quite a while now and I have seen a significant change in my mobility and joint pain. It has helped me so much that I was able to start running last year and have even participated in several 5k runs. I make regular visits to the chiropractor, stay in shape, and maintain a healthy weight, but i believe that taking the Osteo Bi-flex pills has drastically improved my mobility as well as helped to alleviate a lot of the pain that I was experiencing in my joints. I have not personally experienced any kind of side effects from this medication. Another wonderful thing about this medication is that it is available over the counter and is extremely affordable. If you have any kind of joint pain, I highly recommend giving it a try.
