What this means
- 01
NAD+ reaches patients in the United States only through a prescriber, typically for a narrow labeled use or via a compounding pharmacy under a prescription.
- 02
That route depends on a clinician's judgment and, for compounded products, on the pharmacy's own quality controls rather than a product-level marketing approval.
- 03
Buying it online "for research use only" is outside that route, and the label does not make human use lawful.
What NAD+ is
A central metabolic coenzyme marketed via IV and injectable forms for anti-aging and recovery, with declining levels in aging but limited clinical proof for supplementation.
NAD+ is a coenzyme essential to energy metabolism and to enzymes such as sirtuins and PARPs involved in aging and DNA repair. NAD+ levels decline with age, which has driven interest in raising them.
Mechanism: Acts as an electron carrier in metabolism and as a substrate for sirtuins and PARPs; raising NAD+ is proposed to support mitochondrial function and cellular repair.
Regulatory history: Not an approved drug; marketed via compounding and supplements
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
The classification above is the The Longevity Archive reading of U.S. Food and Drug Administration listings for NAD+ at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
