From a business perspective, the FDA has made it very clear that it doesn't consider NMN to meet the definition of a dietary supplements. Most cGMP contract manufacturers won't even consider making products with that in there, a lot of credit card processors have dropped brands for offering it, and some insurance companies are dropping brands for offering it.What are your thoughts on the flood of interest in NMN and NAD+. To be honest I don't really understand what they both are but have heard they're great. I've also heard that most of the sources aren't actually good and it's a waste of money.
It is also one of the most underdosed and outright counterfeited supplements on the market with many scam type brands not even attempting to meet label claims, which is why even before the FDA statement, you didn't see many legit brands even trying to offer it - bc no point doing it the right way and trying to compete with scam brands selling it for less than a legit one costs to make.
And from a personal perspective, I tried one that I do believe to be legit, and its the angriest a supplement has ever made me in my life - so I absolutely would never even consider trying it again myself.
