Flexoplex
I have been taking Flexoplex on and off for several years to combat degenerative OA in both knees (I purchase it directly from the manufacturer's website).  It works.That being said, I'm not a fan of the 'other ingredients' used in this product so I'm going to look for something else that contains some of the same ingredients but without magnesium stearate, silicon dioxide and shellac.
