Mechanism

NAD+: Coenzyme Research Guide

Mechanism review — sirtuins, mitochondrial pathways, and aging/longevity models.

Updated 2026-09 · 5 min read

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme central to cellular energy metabolism. It is studied extensively in aging and longevity research for its role in several conserved pathways. This guide reviews that mechanism as in-vitro research context.

Pathways studied

  • Sirtuin activation — NAD+ is a required substrate for the sirtuin family of regulatory enzymes.
  • Mitochondrial function and biogenesis in cellular models.
  • DNA-repair pathways that consume NAD+.

NAD+ levels and turnover are a recurring variable in preclinical aging models, which is why the coenzyme and its precursors are a large research area. The findings are laboratory findings; they are not claims about human aging or any use of the compound.
