NAD+1000MG
$44.00
NAD+ (nicotinamide adenine dinucleotide) is a critical coenzyme present in all living cells, functioning as an electron transporter in redox reactions (glycolysis, TCA cycle, oxidative phosphorylation) and as a substrate for enzymes such as sirtuins (SIRT1–7), PARPs, CD38/CD157, and SARM1, which regulate DNA repair, gene expression, and cellular stress responses . NAD+ levels naturally decline with age due to reduced NAMPT activity and increased consumption by CD38 and PARPs, contributing to mitochondrial dysfunction and decreased cellular resilience.
