Longevity · NAD+ Science
What is NMN? The upstream molecule behind cellular energy and healthy aging.
NMN (nicotinamide mononucleotide) is the most direct precursor to NAD+, the coenzyme your cells require for energy production, DNA repair, and metabolic regulation. By your 40s, NAD+ levels have dropped 30–50% from peak. Here's what the science actually says about restoring them.
