FDA says that Glucosamin/chondroitin doesnt work. So apparently it didnt stand the test of time. Genera bought their stuff from USP labs, so I guess a bette concentration of goodies can be expected. I do not agree with this whole thing about lower concentrated stuff being better for joints, I would rather believe in homeopathic medications. Ofcourse, you cant swallow 50 of the higher concentrated stuff and expect to get the same results.
