# About NAD Chemical: An Independent NAD+ Research Digest

> NAD Chemical is an independent editorial project summarizing the peer-reviewed NAD+ literature. Not a clinic, not a vendor — a cited digest of the published research.

An independent editorial reading of the NAD+ literature — what the publisher is, and what it is not.

## What this is

NAD Chemical is an independent editorial project that publishes summaries of the peer-reviewed research literature on NAD+ (nicotinamide adenine dinucleotide) and its precursors. We read the published studies — the precursor trials, the mechanism reviews, the brain and IV-therapy work — and lay them out plainly, with every quantitative claim cited to its source. Think of it as a developer-style reference console for one endogenous coenzyme: each finding logged, tagged by evidence strength, and linked back to the study it came from.

## What this is not

We are not a clinic. We do not employ clinicians and we do not provide medical advice. We do not manufacture, sell, compound, or distribute any product — no NAD+, no NMN, no NR, no IV infusions, nothing. Our work is editorial commentary on publicly available science.

The word "chemical" in the name is editorial framing — the register of a fiduciary reference console reading the chemistry of a molecule, not a claim that the site is a supplier or a laboratory. NAD+ is an endogenous metabolite sold elsewhere as a dietary supplement; nothing here is for sale, and nothing here is a prescription.

## How we handle the evidence

We keep three lines clear that marketing tends to blur. First, NAD+ the coenzyme is distinct from its precursors — an oral NMN or NR study is never described as "taking NAD+." Second, route matters: the well-tolerated oral-precursor trials are kept apart from the weak-evidence, unapproved IV/injectable route. Third, raising blood NAD+ is not the same as changing a clinical outcome — we report the biomarker and the endpoint separately, and we flag where a 2025 review found the human efficacy data still limited [1]. When the data stop, we say so rather than fill the gap.

## Sourcing

Citations are drawn from PubMed-indexed journals, randomized clinical trials, and peer-reviewed reviews. Every figure on the site carries a numbered marker resolving to the [full reference list](/references), with DOIs and PubMed links for verification. Where a finding is preclinical or in-vitro, it is labeled as such; where it is a review rather than primary data, that is stated too.

A build-log reading of the NAD+ literature, traced from salvage pathway to brain — the coenzyme kept distinct from its NMN and NR precursors, the oral trials kept apart from the rapidly-cleared IV route, and the contested NMN supplement status logged as filed; no clinic compiles behind this console and nothing here is dosed, compounded, prescribed, or sold.
