NAMPT
NAMPT NAD biosynthesis — the molecular target that 2 compounds in the wiki act on.
In one line: The enzyme that recycles NAD⁺, the fuel your cellular repair crews run on.
NAMPT is the key enzyme in the recycling line that keeps your cells stocked with NAD⁺ — the molecule that powers energy production and your DNA-repair and anti-ageing crews. NAD⁺ levels fall by about half between ages 20 and 50, partly because this recycling slows down.
NAD⁺-boosting supplements (NMN, NR) feed this recycling line more raw material so it can keep the tank full. It's the machinery behind one of the most exciting areas in longevity science — though the human benefits look real but modest, and matter most after 40.
