Today's supplements are extremely versatile with very little to no side effects after continuous use. Pharmaceutical companies, however cannot tout the same side effect free benefits. Starting with ephedra and recently with DMAA, the FDA is slowly easing its way into the control of the dietary supp industry and from the looks of things it's only getting worse. Amazon getting rid of the -racetams is just a preview of the direction that the FDA is moving in. Does anyone else wonder how long the dietary supplement industry will be around before the government and big business interferes?
