Overview

NAD+ (nicotinamide adenine dinucleotide) is an essential coenzyme present in every living cell, central to redox reactions, mitochondrial energy production, and as a substrate for sirtuin and PARP enzyme families — making it one of the most actively studied molecules in current longevity research.

Mechanism & Research Findings

NAD+ serves as an electron carrier in glycolysis, the TCA cycle, and oxidative phosphorylation, while also acting as an obligate substrate for sirtuins (which regulate gene expression, DNA repair, and mitochondrial biogenesis) and PARP enzymes (involved in DNA-damage repair). Because cellular NAD+ levels are well-documented to decline with age in research models, NAD+ and its precursors are central reference compounds in mitochondrial-function, DNA-repair, and aging-biomarker research programs.

Research Applications

• Sirtuin and PARP enzyme substrate research
