The cartographers
About This NAD+ Research Digest
Who makes this map of the literature, and the lines it deliberately does not cross.
What Prescribed NAD is
Prescribed NAD is an independent editorial project that publishes summaries of the peer-reviewed research literature on NAD+ and its precursors. We are not a clinic. We do not employ clinicians and we do not provide medical advice. We do not manufacture, sell, or distribute any product. Our work is editorial commentary on publicly available science — a hand-drawn map of the NAD+ literature, charted from the salvage-pathway sources through the oral-precursor trials to the compounded-infusion edge.
Why the name says 'Prescribed'
The word 'Prescribed' in the name is editorial framing — a cartographer's register for a digest that takes availability, route and regulation seriously — not a claim about anything we offer. To be unambiguous: NAD+ is not an FDA-approved prescription medicine, no legitimate 'prescribe an approved NAD+ drug' pathway exists, and this site neither prescribes nor sells anything. NAD+ is sold as a dietary supplement, most oral products are precursors (NMN, NR, niacin/nicotinamide), and intravenous NAD+ is a compounded, unapproved wellness therapy. We map what the research says about all three; we do not occupy any of those roles.
How we work
Each page leads with what studies actually measured and attributes it to a cited source. We keep one distinction rigorously: NAD+ is the coenzyme, while NMN and NR are precursors the body converts into it — so we never describe an oral-NMN or oral-NR trial as 'taking NAD+'. We report doses only as research context, in the named populations that were studied, and we give no human dosing instructions. Where the evidence is strong (oral precursors reliably raise blood NAD+) we say so plainly; where it is weak or contested (IV infusion efficacy, the NMN supplement-status dispute) we mark it as the caution frontier rather than smoothing it over.
What you will not find here
You will not find product recommendations, brand endorsements, dosing prescriptions, or anything for sale. You will not find claims that NAD+ or any precursor treats, reverses, cures or prevents a disease — the studies measured specific outcomes in specific groups, and that is all we report. We do not invent authors or credentials, and we hold no commercial interest in any NAD+ product. The site is a reading map of the science, maintained as an editorial archive of what the literature has measured.
