NMN & NAD+
NMN vs NAD+: What's the Difference?
Two related abbreviations, two different molecules. A short guide to how NMN and NAD+ differ and why the distinction matters when reading supplement marketing.
NMN and NAD+ are often mentioned together.
Sometimes they're discussed as though they're interchangeable.
They're not.
What is NAD+?
NAD+ stands for Nicotinamide Adenine Dinucleotide.
It is a coenzyme found in cells and participates in fundamental metabolic reactions.
What is NMN?
NMN stands for Nicotinamide Mononucleotide.
NMN participates in pathways through which the body produces NAD+.
It is therefore commonly described as an NAD+ precursor.
NMN vs NAD+ in simple terms
NMN = precursor involved in NAD+ production. NAD+ = coenzyme involved in cellular metabolism.
They're different molecules connected through NAD+ biosynthesis.
NMN and NAD+: What's the Connection?Why are scientists studying NMN?
Researchers have investigated whether oral supplementation with NAD+ precursors can influence NAD+ concentrations.
Human trials provide evidence that oral NMN can influence NAD+-related biomarkers.
A 12-week trial investigating 250mg NMN daily reported increased whole-blood NAD+.
Scientific reference
Another trial investigating 300mg, 600mg and 900mg also reported increases in blood NAD concentrations.
Scientific reference
Does increasing NAD+ reverse ageing?
That conclusion goes substantially beyond current evidence.
NAD+ metabolism is an important area of ageing research.
Demonstrating a change in NAD+ concentrations is not equivalent to demonstrating that a supplement reverses human ageing.
