NMN is a precursor the body converts toward NAD+, a coenzyme central to energy metabolism. Both are popular in longevity circles; human evidence is early.
NAD+ is a coenzyme essential to cellular energy and repair; NMN is one of its precursors. Supplementing NMN is intended to support NAD+ levels. The longevity interest is real, but human clinical evidence is still early and modest — worth understanding honestly rather than overselling.
| NAD+ | NMN | |
|---|---|---|
| What it is | Coenzyme (NAD+) | Precursor to NAD+ (NMN) |
| How it's taken | IV or precursor supplementation | Oral supplement |
| Human evidence | Early; mechanistic interest strong, outcomes modest | Early human studies; long-term outcomes unproven |
| Regulatory status | Varies; not an approved anti-aging therapy | Sold as a supplement; status has shifted in some markets |
| Honest take | Promising biology, unproven longevity claims | Promising biology, unproven longevity claims |
The science is genuinely interesting but the human longevity evidence is not there yet. Treat bold anti-aging claims skeptically, and discuss any supplement plan with a provider.
