I bought a pkg of 30 NADH tablets from Life Extension Foundation in Ft Lauderdale, FL. I took them as follows, beginning on 10/26: 1 tablet/day 10/26-10/29 no effect 2 tablets/day 10/30-11/2 no effect 3 tablets/day 11/3-11/4 no effect 4 tablets/day 11/5-11/7 no effect Did I try it long enough? I have what was diagnosed as "atypical parkinsonism" and I get no effect from Sinemet either. My symptoms are primarily walking and balance difficulties. I can walk once started but my legs "freeze" as I try to start, turn, go through a door or when my steps get too short as when climbing a hill. I fall a lot. I wear sports knee pads to protect my knees. I have no tremor. ---Milo 70/3 Milo V. Anderson, Ph.D. Box 417 Angwin, CA 94508 voice 707 965 2508 fax 707 965 3148 e-mail [log in to unmask]
