NMN is one of the most talked about supplements for longevity.
But does it actually work?
Short answer
It might—but not in the way most people think.
What it’s supposed to do
NMN is meant to increase NAD levels, which are involved in energy production and cellular function.

What actually matters
If you’re optimizing basics (sleep, nutrition), NMN may add small improvements.
If not, it’s not a magic fix.
