Hi all. I have heard many mixed comments about NADH. Can anyone mention specific comments that are positive and why that would be. I realize this may be difficult, but my mother's neuro has said not to bother with it. She will, though, if there is something more concrete than " it helps" to go by. All info is appreciated and thanks. Renee, part-time cargiver for Judy (75, 65, 63).
