I've only been using NMN for a couple of weeks and my experience has been very positive. My
energy level has
increased dramatically as well as improvements in mood and sleep quality. From what I've read there's fake NMN being sold and if anyone wants to try it, I suggest reading the Amazon reviews and narrowing it down to products with 4.5 stars. Then read individual reviews submitted by verified purchase of the product. It may or may not be efficacious for you. I'm a 'senior citizen' which would indicate that my NAD levels were very low. So what's effective for me, might not be effective for someone else. I hope that the FDA doesn't ban this as a supplement, resulting in it becoming available only by prescription being sold at an inflated price.
My only advice to others is to Google NMN and read reviews from reputable sources such as the NIH National Library of Medicine website.

Abundant Evidence for Anti-aging and Health-Enhancing Effects of NMN
In numerous
mouse models of disease and aging, NMN has demonstrated a wide array of remarkable effects, benefitting conditions ranging from diabetes to Alzheimer’s disease to ischemia.
27 Orally administered NMN is quickly synthesized into NAD+ in tissues in mice. NMN has been able to suppress age-associated weight gain, enhance energy metabolism and physical activity, improve insulin sensitivity, improve eye function, improve mitochondrial metabolism and prevent age-linked changes in gene expression."
