They are trying to make a drug out of what you can already buy over the counter, Resveratrol. They also want to regulate NMN which is the precursor to NAD+ which increases surtuin activity. Sirtuins repair telomeres which essentially are the end of your DNA strand. According to David Sinclair,.the author or "Lifespan, Why We age and Why We Don't Have To" our DNA is being damaged so fast because of all the shit in our environment that the sirtuins basically can't keep up, get lost from putting out fire after fire and we essentially need to make more. The book is a plethora of info that will make your head spin and I don't agree with some of his comments but overall this information is worth reading it for. I have been taking NMN and Resveratrol for a year and a half and have had several NAD+ IVs. I immediately noticed a difference in my ability to recover from my CrossFit workouts. I also gave NMN to my high functioning autistic, ADHD son for several months and there was an obvious change. After years of needing to be in a self contained classroom (aka special Ed), struggling with focus, behavioral issues, clothing/shoe sensitivities and so much more, this year he has moved into the Gen Ed class and is doing great. I think the FDA now wants to regulate NMN and NAD+ because these drug companies want to profit from this science.
