SUPER NMN, 99% Pure Nicotinamide Mononucleotide Powder, 25 Grams. High Absorption, Sublingual Powder. Freeze-Dried process. The ONLY stabilized form of NMN. Purity Certified by 3rd Party USA Lab.

I have not conducted my own third party testing to verify purity. I was using Renue by Science NMN but availability has been inconsistent. I have not noticed any difference in how I feel since switching to this brand so I am assuming it is providing me the same benefit.

Excellent, I wrote an earlier review where I was skeptical. I've compared it to some other sublingual products NMN and NR, and I much prefer the purity of this one. So a big thanks to the company Megaresveratrol.

I took it today. At first, I felt rather sleepy but when I took the second dose at night i find it very difficult to fall asleep as my brain became rather energetic

Works!
