Bests & Worsts Reviews from Amazon

I have been taking this product for about 6 months now, and I plan on taking it for much longer. I have not been paid, have not been given any free product, have not even talked to the seller or maker of this product. Decided to try it after reading scholarly and anecdotal articles about NAD supplements. Dose has been 1 (one) 500MG capsule of this brand every morning faithfully for 6 months. First, I have not noticed a single bad side effect. No flushing, no gastro problems, no negative mental side effects, nadda. Here's what I did notice on the plus side (and since there's no double blind study, this is anecdotal): Increased energy, both mentally and physically. Heightened attention, which is my biggest plus... since I honestly have a touch of attention deficit disorder. At work this is where I notice that the most. Procrastination of simple tasks just because I'd rather poke around on Facebook or look for deals on the web, or forums, and many other things. I still do that to some degree, but it's much, much less pronounced. I focus better at day to day tasks, and found myself much more engaged, productive and entertaining at meetings, many of which I usually lead. I notice hangovers are much less uncomfortable. I'm now in my 50's and have noticed wrinkles on my face have diminished, mostly those crows feet and eye "bags" and wrinkle bunches. I am convinced my fingernails grow faster! I'm not bald, but thinning somewhat. That's one area this doesn't seem to have any affect, I don't think my hair has thickened. So that's my honest opinion about my experience. And this stuff is inexpensive as well. Oh, and I can't say it has improved sleep, I generally don't have sleep problems.
