Hi Margaret, my wife and I have been taking Tru Niagen for about 6 or 7 years. She takes 300 mg every day, I take 450 mg, but only on certain occasions, mostly when I am going to do a lot of driving on a given day. We both take a number of supplements. With most of them it is not easy to notice their effect. With a few it is and Niagen is one of those. Whatever else it does for me, I notice a definite effect on me when I am driving. I am more alert, more focused, it is easier to focus for a long time, hours in fact. Driving, which is usually boring as heck actually becomes in some weird way interesting to me. Less than 450 mg and I don't seem to notice this as much. I take it with breakfast and notice its effect all day. It's important to take it with food.

I think for me it acts as a brain enhancer. The reason I do not take it every day is that on days when I am not driving I don't notice the overt effect as much. Right now the one day each week I always take it is when I am going to be driving for the Red Cross delivering blood to hospitals. I take it to be safe on those drives, to be alert on my drive.

It's not cheap, but I probably should still take it every day like my wife does. It's just that I view it more as a tool to use when needed. I think I worry that if I take it every day it won't work as well for me. I do not know this to be true, but I have formed a habit of this style of use. Now that I am writing this I am starting to think maybe I should start to take it every day for a while just to test my theory.

Anyway, since you mentioned it I thought I would give it an endorsement since I know it has had a positive effect for me. Hope you see benefits from it also.

Best, Hank
