Donald Cronkite Thank you for very much for that wonderful explanation of what NADH is. If you are interested in reading Dr. Birkmayer's explanation on how NADH is used in the body to stimulate natural dopamine production, you can find it in an excerpted work of DR. Birkmayer that John Cottingham posted to the list. It is in the PARKINSN database at 3970. I would be interested in any thoughts you might have after reading this, or any other of your explorations, on the connection NADH has to our symptoms. Thank you again, Diane -- Diane Turner [log in to unmask]
