Dear Tina: <<My Dad has Parkinsons and I have been printing out the messages from this group to show him. He is very interested in the NADH. He and my Mom went to a health food store yesterday to look for it. They found Coenzyme 10 instead of Coenzyme 1. They want to know if this is the same thing. Does anyone know?>> No, Coenzyme 1 is different. For information, you should see the Chronic Wellness web pages at: http://ourworld.compuserve.com/homepages/chronicwellness I hope this helps.
