A step from NAD+.

NMN sits one step away from NAD+, the coenzyme that powers cellular energy and repair. Raising NAD+ as it declines with age is one of the most active ideas in longevity and NMN is the most discussed way to try.

01
Direct precursor
Converts to NAD+ in cells in a single step.
02
Raises NAD+
Human studies show it increases NAD+ markers.
03
Regulatory limbo
The FDA moved to exclude NMN as a supplement; the status is contested.

Where the research focuses.

01
NAD+ restoration

Raises NAD+ levels in humans - its best-documented effect.

02
Metabolic health

Studied for insulin sensitivity and energy metabolism.

03
Vascular function

Early human signals on blood-vessel and physical function.

04
Healthy ageing

Central to NAD+-based longevity research.

05

Refilling the tank.

NAD+ is essential and declines with age; NMN is studied as a way to refill it, with human data showing higher NAD+ levels after supplementation.

Whether that translates to ageing benefits in people is still open and its US regulatory status is genuinely unsettled.

06

Strength of the evidence.

Tier 01
Strongest support
  • Raises NAD+ in humans
  • NAD+ biosynthesis pathway established
Tier 02
Moderate support
  • Metabolic and vascular signals
  • Small human trials
Tier 03
Emerging / unverified
  • Human lifespan / healthspan claims
  • Optimal dose and form

Sirtuins

Higher NAD+ fuels sirtuin repair enzymes.

Mechanistic
03
Metabolism

Studied for insulin sensitivity and energy.

Signs of a quality compound

Lyophilised cake or powder
A fine, fluffy white cake — not oily, clumped or discoloured.
Clear reconstitution
Dissolves to a clear, colourless solution with no visible particles or cloudiness.
Batch-specific COA
Independent HPLC purity and mass-spec identity for the exact lot — not a recycled generic PDF.
Intact seal & vacuum
Sealed flip-top vial under vacuum; correct fill; legible batch and storage marking.
Walk away if…
No COA, oily residue, off-colour, partial vacuum, or purity claims with no independent test behind them.
Suspiciously cheap
Pricing far below the market for a well-tested compound usually means skipped testing or underfilled vials.
Regulatory & status
Popular, contested.

NMN is sold widely as a supplement, but the FDA moved to exclude it from the supplement category while it is investigated as a drug - leaving its US status contested. It is not an approved drug.
