Maya here. Let's untangle one of the most confusing corners of the longevity shelf.
Few molecules have been written about as breathlessly as NAD+. It sits at the centre of how every cell turns food into usable energy, and it powers the repair enzymes — sirtuins, PARPs — that keep our DNA tidy. The catch is simple and well documented: NAD+ levels fall as we age. The interesting question is what, if anything, to do about it.
You cannot swallow NAD+ directly and expect much; the molecule is too large and unstable to survive digestion intact. So the field turned to precursors — smaller building blocks the body can convert. The two you will see most often are NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside). Both reliably raise NAD+ in blood and tissue in human trials. The honest summary is that the biochemistry is solid and the downstream “live longer” claims remain under study.
What does that mean for a considered routine? We think of NAD+ support as a foundation, not a miracle. The people who tend to notice something describe steadier energy and better workout recovery rather than a dramatic switch being flipped. Dose transparency matters here more than almost anywhere — a precursor only helps if it is actually dosed at studied levels, which is why we avoid proprietary blends that hide the number.
A few practical notes we stand by: take it consistently rather than occasionally, since NAD+ support is a gradual project; pair it with the basics that also raise NAD+ for free — sleep, movement, and not overeating; and don't expect a stimulant. This is plumbing, not caffeine.
If you want to explore the category, our Anti-Aging & Longevity collection carries dosed NMN and NAD+ formulas with the full label printed, nothing hidden.
