Bests & Worsts Reviews from Amazon

I've been taking Tru Niagen for almost a year now, with the exception of a few weeks (as a test). I'm hoping my telomeres are retaining their length, but I have no way to measure them. What I can tell you is that I feel like It gives me energy - I don't feel as tired or lethargic when I take it. During the three week abstention period, I could tell a definite difference. While the improved energy was incremental when I began taking it, the abrupt removal illustrated its beneficial effect. So, I've been taking it ever since. I don't see any significant differences with sleep or pain relief, but do think my hair is thicker. As I have rotator cuff issues and perimenopausal hot flashes disturbing my sleep, I wouldn't discount pain relief and improved sleep if you have less extreme issues. The product is a little pricey, but packaged beautifully. Overall, I recommend Tru Niagen and will continue taking it for the foreseeable future.
