RESEARCH DIGEST / ABOUT
About Medicinal NAD.
An independent editorial project that reads the NAD+ literature in layers and reports what the studies measured.
What this site is
Medicinal 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.
The site is organized as a layered reading of the evidence — the coenzyme at the base, the oral precursors NMN and NR stacked above it, and the whole-blood NAD+ that randomized trials actually measured brought to the front. The design mirrors the science: what is best supported sits nearest the reader, and the open gaps recede, labeled as gaps.
What "medicinal" means here
The word "medicinal" in this site's name is editorial framing — the measured, evidence-weighing register of a research digest — not a claim about services. This site does not prescribe, does not run a telehealth pathway, and does not imply that NAD+ is an approved prescription medicine. NAD+ is sold as a dietary supplement, is not FDA-approved to treat any disease, and most oral products are precursors rather than NAD+ itself. We summarize that literature; we do not practice medicine and we do not sell anything.
How we handle evidence
Every quantitative claim on this site is tied to a specific study, listed on the references page with a DOI or PubMed link. We keep the NAD+-versus-precursor distinction precise: when a trial gave participants NMN or NR, we describe it as a precursor study, never as "taking NAD+." We describe what was measured in which species at which dose by which route, and we do not convert research doses into instructions for any person. Where the human evidence is thin — the injectable route, hard clinical endpoints — we say so plainly rather than overstate it.
What we do not do
We do not give dosing recommendations, diagnose, or suggest NAD+ or any precursor as a treatment for any condition. We do not endorse or name any commercial supplement brand. We do not sell, link to vendors, or take part in the marketplace we describe. If you are weighing any supplement or therapy, that is a conversation for a qualified clinician who knows your history — not for a digest of the published literature.
