THE BILLBOARD / ABOUT
About Reviews NAD
A billboard-scale reading of the NAD+ literature — opinionated about the evidence, scrupulous about the citations.
What this site is
Reviews NAD reads the peer-reviewed research on NAD+ and its precursors the way a billboard reads a landscape — the sturdy findings set in large type, the shaky ones qualified in the line beneath. No clinic stands behind the broadcast: nobody here treats, diagnoses, or prescribes, and there is no medical advice on the board. Nothing is manufactured, stocked, or sold either — what goes up is the evidence, cited, and nothing else.
The name carries the word 'reviews,' and that is exactly the register: we review the published evidence — the randomized precursor trials, the mechanism and aging literature, the recent meta-analyses — and report what each study actually measured. 'Reviews' here means the editorial act of weighing the research, never a storefront, an IV lounge, or a supplement shelf.
How we read the evidence
Our editorial line is simple and consistent. When the controlled trials agree on something — that oral NR and NMN raise whole-blood NAD+ dose-dependently [4][3] — we say so plainly and at scale, because reproducibility across randomized trials is itself worth surfacing. When the evidence is thin or mixed — IV NAD+'s pilot-grade data [10], the unproven hard human endpoints [10], the NMN meta-analysis null on metabolic markers [14] — we mark the gap as clearly as the finding. We keep one distinction exact throughout: NAD+ is the coenzyme, NMN and NR are precursors, and a study that dosed a precursor is never described here as 'taking NAD+.'
What the name does and does not mean
A word on framing. NAD+ is regulated as a dietary supplement, not an approved medicine, and nothing here implies otherwise. Findings are described in study-attributed language, with no dosing instructions and no medical recommendations. The 'reviews' on the board is a vantage over the literature — a reader and summarizer of it — not a service, a treatment, or a trade. Every number is sourced; if a claim is not in the cited research, it does not go up. For the studies themselves, see the full reference list.
