For a long time I've had problems with my ankles.
Running, or any kind of shock to the ankle joint would cause severe pain.
This spring I started taking this collagen-glucosamine complex, and about a month and a half later all my ankle pain was gone, and I could run again without any problems. I played tennis all summer, and still no problems.
All I can say is, it worked for me.
