About NAD Medicine

What this site is

NAD Medicine is an independent editorial project that publishes summaries of the peer-reviewed research literature on NAD+ (nicotinamide adenine dinucleotide) and its precursors, NMN and NR. 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 project exists because the NAD+ field is unusually prone to confusion. The coenzyme, its oral precursors, the vitamin-B3 forms, and the unapproved IV route are constantly conflated, and a great deal of what circulates online overstates the human evidence. Our editorial job is to keep those entities distinct and to report only what specific studies measured.

About the name

The word "medicine" in NAD Medicine is editorial framing — a position this publisher takes relative to the scientific literature, not a claim about services we offer. We are not a medical practice, a pharmacy, or a telehealth provider. There is no NAD+ "prescription" pathway here, because NAD+ is not an approved drug; it is sold as a dietary supplement, and most products are precursors rather than NAD+ itself.

We do not present NAD+ as a treatment for any condition. Where the literature reports a measured outcome — a rise in blood NAD+, an improvement in muscle insulin sensitivity — we state what was measured, in which species, at which dose, and cite it. Where the evidence is weak or absent, we say so plainly.

How we handle the evidence

Every quantitative claim on this site is tied to a numbered citation on the full reference list. We favor randomized human trials and peer-reviewed reviews. We distinguish what is well established (oral precursors raise blood NAD+) from what remains preliminary (benefit for hard clinical endpoints in humans). We do not name or endorse any commercial supplement brand, and we give no dosing recommendations. When the research updates, the digest is meant to update with it.
