Something doesn't seem right
I believe them to be dishonest in their claim that their NMN is "pure". According to my friend who's been researching NMN (in a lab and clinical setting) for at least a few years, NMN would burn if you put it in your mouth. The NMN we've gotten from other sources is much more acidic tasting and "fluffy" (affected by static and presumed to be lightweight/low-density for the particle size). What we got from this supplier didn't fit either quality and didn't have the same perceived health benefits. I am all ears and ready to alter this review if someone has information to prove my assessment is incorrect. PS Purchase with a credit card so that, if you get something other than what you agreed to purchase, you can dispute the charge rather than pay the return shipping and high restocking fee companies try to charge illegally when they sell you something other than what's advertised or agreed upon.
