I have been using Niagen for about 9 months. I feel less fatigued, sleep better, and have noticeably less stiffness in my joints.

I have been taking NAD3 for several months now. It is one product that I use that I definitely can tell a difference. I have run out before I order and that was a mistake. What is the difference? Energy. I work 12-14 hours a day and for a 65 year old NAD3 provides the energy I need to get through the day with assurance that I am not going to be sluggish.

I received my package quickly. I have already ordered such product. I have no complaints. I have chronic fatigue and I have noticed more energy for sure. Ask me a little later and maybe I could rave more. But I definitely think I don’t want to live without it!!

This stuff has really turned around my mental awareness. I had been feeling dull and lethargic but since being on it the past 2 months or so I’ve had so much more energy and felt so much better. I don’t know the full science behind it but my doctor recommended it and that’s good enough for me.

I take this supplement every morning along with some other supplements + anti-oxidants. I believe this supplement is energy enhancing because I get only 3-4 hours sleep at night & after taking this I am able to accomplish many things before I ever get the coffee brewing. There are many demands & responsibilities required of me first thing in the morning & I am able to manage them with speed & enthusiasm. The only vitamin I’ll ever need !
