Over the last five years there were close to 1000 messages on the PARKINSN mailing list that mentioned CoQ1 and/or CoQ10 - at least over 850 showed up on my search of the archives. After reading all and deleting the dups and irrelevants and some questionables, I came up with the following summary about NADH (CoQ1). There were 37 members who posted that they or their PWP were/had used it. Of these 8 (22%) expressed no opinion 23 (62%) where somewhat to very positive that the NADH helped (but for differing reasons.) 1 (3%) had a negative reaction and stopped using i, and 5 (14%) felt that the NADH did no make any difference. NADH users - no opinion - 8 NADH users - pro - 23 NADH users - con - 1 NADH users - no difference - 5 --------------------------------------------------------------- Non-users - pro - possibly NADH vendors - 3 --------------------------------------------------------------- Non-users con - 3 (with srong credentials such as Ph.D. in biochemistry) FWIW
