What is NMN (Nicotinamide Mononucleotide)?
Nicotinamide mononucleotide (NMN) is a nucleotide derived from niacin (vitamin B3) that serves as a direct biosynthetic precursor to nicotinamide adenine dinucleotide (NAD+) - a coenzyme essential for cellular energy production, DNA repair, sirtuin activation.

How to take it
- Standard dosage: 250-500 mg per day
- Research dosages: Human trials have used 250-1,000 mg daily with good tolerability
- Timing: Best taken in the morning, as NAD+ levels naturally peak during the day and decline at night. Morning dosing aligns with circadian NAD+ rhythms
- Sublingual vs oral: Some evidence suggests sublingual absorption may be more efficient than swallowed capsules
- Storage: NMN is hygroscopic and degrades with heat and moisture. Store in a cool, dry place; some products require refrigeration
Watch out for
- Well tolerated in clinical trials: Doses up to 1,200 mg/day have been well tolerated in human studies with no serious adverse events reported
- Mild side effects: Occasional nausea, headache, or flushing at higher doses
- Cancer consideration: Theoretically, raising NAD+ could fuel rapidly dividing cells. While no clinical evidence supports this concern, individuals with...
- Quality variation: The NMN supplement market has significant quality variation. Choose products with third-party purity testing (HPLC verification)
- Regulatory status: Available as a dietary supplement in the UK and EU. FDA status in the US has been contested
The science, if you're curious.
- Directly converts to NAD+ via NMNAT enzymes, restoring the coenzyme essential for cellular energy production in neurons
- NAD+ is the required cofactor for sirtuins (SIRT1-7) - enzymes that regulate DNA repair, inflammation, mitochondrial biogenesis, and neuroprotection
- Restores NAD+ in the mitochondrial matrix, supporting the electron transport chain and ATP production in energy-demanding neurons
- NAD+ is consumed by PARP enzymes during DNA repair. Declining NAD+ impairs the brain's ability to repair DNA damage, accelerating neuronal ageing
Where to find it
- Capsules and powder: Available from longevity-focused supplement companies in various dosages (125-500 mg)
- Sublingual tablets: Designed to dissolve under the tongue for enhanced absorption
- Lozenges: Slow-dissolve formulations for buccal absorption
- Purity testing: Look for products with certificates of analysis showing 98%+ purity via HPLC testing
