I am looking for information on NADH. I just went to a health food store and inquired about it. They did not have it but it is listed in the SOLARAYcatalog. Yes, it is expensive: $48.- for 30 pills (5mg). Does anybody know what a reasonable dosage is for my wife who is on 3xdaily 25/50 Sinemet CR and 2xdaily Eldepryl. Thanks, K-F ([log in to unmask])
