My husband self medicates with nadh. It's a liquid that is administered by drops. He also takes an enormous amount of anti-oxidants and vitamin supplements and others on this list have no doubt heard me say that it indeed is helping him. Not curing--helping. He has much energy and it really keeps him going. I also know there is a dr. in Austria who does a specific therapy with nadh and the neurologists we've spoken to feel there's not much to it because if there were, more people would be doing it. It might be useful to check with much younger onset pd's because much of what I've read is that nadh is much more helpful at the beginning stages of pd as well as with young onset. Good luck. Den
