NMN and Longevity: What the Latest Science Says
Share
NMN's connection to longevity has moved from theoretical to practical. The question is no longer 'can NMN extend lifespan?' but 'how should we use it for optimal healthy ageing?' Here's what the science actually shows.
The Hallmarks of Aging
Aging is driven by nine cellular hallmarks, genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, altered intercellular communication, and deregulated nutrient sensing. NAD+ decline is implicated in multiple hallmarks, making it a central target for intervention.
NMN and the Hallmarks
- Mitochondrial function, NMN restores NAD+ that powers mitochondrial energy production
- DNA repair, NAD+ is a substrate for PARP enzymes that repair DNA damage
- Sirtuin activation, NAD+ activates sirtuins, the longevity proteins that regulate cellular health
- Inflammation, NAD+ supports immune function and regulates inflammatory pathways
Is NMN an 'Anti-Aging' Supplement?
Strictly speaking, nothing is proven to 'reverse' aging in humans, not yet. But NMN is one of the few compounds with a clear, evidence-backed mechanism for slowing aspects of cellular aging. It addresses the energy decline, DNA repair deficits, and mitochondrial dysfunction that are hallmarks of getting older.
