A simple explanation of nicotinamide mononucleotide (NMN), NAD+, and why they matter as we age.

NMN and NAD+

NMN (nicotinamide mononucleotide) is a precursor to NAD+, a coenzyme involved in cellular energy metabolism. Your cells rely on NAD+ to convert nutrients into usable energy and to run many of the everyday maintenance processes that keep them functioning.

NAD+ levels naturally decline with age. NMN is studied for its role in supporting these levels — by supplying the raw material cells use to produce NAD+.

What it may support

  • Cellular energy production
  • Cognitive clarity and focus
  • Everyday recovery and resilience

How Celvity’s NMN is made

Enzyme-based production

Our NMN is produced through clean enzymatic synthesis rather than harsh chemical processes — giving a purer starting material with strict control over contaminants.

European-sourced, certified manufacturing

The NMN ingredient is sourced in Europe, with final manufacturing completed in GMP and FSSC 22000-certified facilities in the Netherlands and Lithuania. Every batch is tested to ≥99% purity, with heavy metals verified below 0.1 ppm.

A clean, single-ingredient formula

Each capsule delivers 250 mg of 99.9%-pure NMN, with only stone-ground rice flour as a natural bulking agent — no artificial additives, fillers, or EU-regulated allergens.

How to take it

The suggested use is one capsule a day, preferably in the morning.
