What's the Difference Between NAD+ and NMN/NR?

NAD+ is the finished coenzyme molecule (≈663 Da) that participates directly in over 500 enzymatic reactions, including sirtuin activation and PARP-mediated DNA repair. Because it is the end-product molecule itself, research use of NAD+ raises tissue NAD+ levels without requiring an intermediate conversion step.

NMN and NR are both smaller precursor molecules positioned earlier in the NAD+ biosynthesis pathway — the body takes them up and enzymatically converts them into NAD+ over time, meaning their research effect depends on that conversion process working efficiently in the system being studied. This is the core mechanistic distinction researchers weigh when choosing between NAD+ directly and one of its precursors for a given protocol.

REVIVE LAB UAE currently stocks NAD+ directly (100 mg vials, ≥99.0% HPLC purity) — it does not carry NMN or NR as separate SKUs, so this comparison reflects general research literature rather than a REVIVE LAB UAE product lineup.
