I have been using this product for several years now and it really works. I was having regular back pain and did a lot of research into what supplements might help. I was pleased with the results I got from Flexoplex. I take it daily and have little to no back pain. If I miss it for a few days in a row, the pain starts to come back. So, I know it continues to work. I have recommended this supplement to several people, even giving them a bottle to try. It has helped them as well. I wish it were a bit less expensive, but its hard to put a price on eliminating pain.
