NAD+ and the quest to refuel aging cells
This molecule powers your cells and declines with age. The supplement story is more nuanced than the marketing.

AI summary — public Q&A, biochemistry researcher
NAD+ is a molecule every cell needs to produce energy and run repair systems, and its levels decline measurably as we age.
Precursor supplements aim to top it back up. Lab data is genuinely interesting, but human evidence for anti-aging benefits remains thin.
The researcher's honest framing: exercise is the one intervention shown reliably to raise NAD+ — start there before reaching for a bottle.
Key takeaways
1NAD+ is essential for cellular energy and repair.
2Levels fall with age; boosting them is an active research area.
3Exercise reliably raises NAD+ — supplements are still unproven.
