NMN & NAD+
NMN vs NR: What's the Difference Between These NAD+ Precursors?
Nicotinamide mononucleotide and nicotinamide riboside are both NAD+ precursors, but they enter NAD+ biosynthesis differently. Here's what the evidence supports.
If you've researched NAD+, you've probably encountered two abbreviations: NMN and NR.
Both are associated with NAD+ metabolism, but they are different molecules.
What is NMN?
NMN stands for nicotinamide mononucleotide.
It is an intermediate involved in NAD+ biosynthesis.

NR stands for nicotinamide riboside.
NR is another NAD+ precursor.
It can be converted through biochemical pathways that ultimately contribute to NAD+ synthesis.
What do NMN and NR have in common?
Both compounds have been investigated because of their relationship with NAD+ metabolism.
However, they enter NAD+ biosynthesis through different biochemical steps.
NMN vs NR: which is better?
This is where marketing can get ahead of science.
Current evidence does not justify declaring one universally superior for all purposes.
Studies vary considerably according to:
- dosage
- population
- duration
- study design
- biomarkers
- clinical outcomes
Human research has demonstrated that oral NMN can influence NAD+-related measurements.
Scientific reference
But whether NMN or NR ultimately produces superior long-term health outcomes requires considerably more research.
Why does VitamiQ use NMN?
NMN is the compound selected for VitamiQ's first product because it is an interesting and rapidly developing area of nutritional and ageing research.
We don't believe selling NMN requires pretending that every scientific question surrounding it has already been answered.
