If you've gone down the NAD rabbit hole, you've hit a wall of acronyms: **NAD+, NMN, NR.** They get used almost interchangeably in marketing, but they're not the same. This guide untangles them in plain language — and is honest about what the science does and doesn't yet show.

## The simple version

- **NAD+** (nicotinamide adenine dinucleotide) is the **coenzyme** your cells actually use, central to turning nutrients into energy. (Full explainer: [what NAD+ is](/blog/what-is-nad-coenzyme-explained/).)
- **NMN** (nicotinamide mononucleotide) is a **precursor** — a building block the body can convert toward NAD+.
- **NR** (nicotinamide riboside) is **another precursor**, similar in concept to NMN.

A useful mental model: **NAD+ is the destination; NMN and NR are roads that may lead toward it.**

## Why "which is best" is unsettled

Supplement marketing loves to crown a winner — NMN over NR, or precursors over direct NAD+. The honest reality is that the **human evidence on how much any oral precursor actually raises NAD levels is still emerging and mixed**, and results vary by product and study. Confident rankings are getting ahead of what's been shown in people.

What *is* well established is NAD+'s role as a coenzyme in cellular energy metabolism. What's *less* settled is the best way to support it and how the options compare — which is exactly why grounded, individual guidance beats a marketing claim.

## Precursor supplement vs prescribed NAD+

These are two different lanes:

- **NMN / NR supplements** — over-the-counter, unregulated category, emerging evidence
- **Compounded NAD+** — a prescription preparation made by a state-licensed pharmacy, with provider oversight (and, importantly, also not FDA-approved as a finished product)

Neither is a magic bullet, and which — if either — makes sense for you is a clinical conversation.

> **Want a provider's grounded take?** [REMEVi prescribes NAD+ online](/nad-injections/) — injection, nasal spray, or oral dropper — after a licensed US provider reviews your case. $145 for a 4-week subscription, bilingual care.
