NMN
Nicotinamide Mononucleotide
A direct precursor to NAD+, the critical coenzyme involved in cellular energy production and DNA repair. NMN supplementation raises NAD+ levels, supporting mitochondrial function, metabolic health, and healthy aging. Central to David Sinclair's longevity research and Bryan Johnson's Blueprint protocol.
How NMN Works
NMN is converted to NAD+ via the enzyme NMNAT. NAD+ is essential for sirtuin activation, PARP-mediated DNA repair, mitochondrial function, and circadian rhythm regulation. NAD+ levels decline ~50% between ages 40-60, making supplementation a key longevity strategy.
📊 Evidence by Outcome
Consistently shown to raise NAD+ levels in human trials. A 2024 meta-analysis confirmed significant NAD+ increases across multiple dosing protocols.
18 studies • Consistency: High • Effect: Large
Improved insulin sensitivity and lipid profiles in clinical trials. Benefits more pronounced in overweight or metabolically unhealthy individuals.
12 studies • Consistency: Moderate • Effect: Moderate
Enhanced aerobic capacity and reduced fatigue in older adults. Community reports consistently highlight improved energy within 2-4 weeks.
8 studies • Consistency: Moderate • Effect: Moderate
Animal studies show robust lifespan extension and biological age reversal. Human epigenetic clock data emerging but limited. Long-term outcomes still being studied.
7 studies • Consistency: Mixed • Effect: Unclear

Estimated UAE pricing. Costs vary by provider, dosage, and treatment plan.
Frequently Asked Questions
Both raise NAD+ levels. NMN may have a slight edge in bioavailability due to a newly discovered direct transporter (Slc12a8). NR has more clinical trial data. Many longevity researchers consider them interchangeable.
Quality NMN costs AED 300-800/month ($80-$220) depending on dose and brand. Prices have dropped significantly since 2022 as manufacturing scaled up.
