In response to Ivan's request for NADH info...I used NADH for over a year, most of the time taking 10mgs/day upon rising on a completely empty tum, not eating for at least a half hour. I also felt that my movements were quicker and more fluid, frequently experienced a hot prickly thing, especially in the morning. Recently I tapered off NADH as I increased ALC, with no discernible difference in function (to me anyway, but most of the time I'm the last one to ask about my functioning). Hope this helps, Kathie Tollifson [log in to unmask]
