Thanks to Linda Forrest's Mom & Fred W. Schaffert for replying to my question about how to determine the appropriate dose of NADH for my mother. However, Mr. Schaffert, I don't understand why you comment that it's unlikely that the NADH is getting into her system at present; could you explain please? (As I noted, I am currently giving her a 1.8mg NADH pill together with her Sinemet, 7 times a day; that's every 3 hours starting at 6:00am and ending at midnight.) Thanks. -- SJS
