I have seen many suggestions on this list and others that vitamins, NADH, CQ10 may be of value but have not seen any sources for these supplies. It seems that the source of these vitamins is important and may be a significant cause of confusion as to why they work for one person and not for another. Does anyone have any comparative information on the various brands. For those of you who are nice enough to share your successs could you also include brand names? I don't think this would violate internet regs on advertising. Thanks! -- Best regards Mike Email at [log in to unmask]
