NAD+
Essential coenzyme found in all living cells, extensively studied for its role in mitochondrial function, DNA repair, and aging research.

What Is NAD+?
NAD+ (Nicotinamide Adenine Dinucleotide) is a fundamental coenzyme present in every living cell, composed of two nucleotides joined through their phosphate groups. As a research compound, it has attracted substantial scientific interest for its central role in redox reactions, cellular energy production, and the regulation of longevity-associated enzymes such as sirtuins and PARPs.
Its underlying biological role relates to electron transfer during cellular respiration and the activation of enzymes that maintain genomic stability and metabolic homeostasis. Studies indicate that NAD+ levels decline progressively with age, and its restoration is associated with improved mitochondrial efficiency, enhanced DNA repair, and modulation of inflammatory pathways (Verdin, 2015).
Mechanism of Action
NAD+ is studied for its dual function as both a redox cofactor and a signaling substrate. Through interconversion with NADH, it shuttles electrons between metabolic pathways and supports ATP synthesis via oxidative phosphorylation (CantΓ³ et al., 2015). It also serves as a co-substrate for sirtuins (SIRT1βSIRT7), poly(ADP-ribose) polymerases (PARPs), and CD38, regulating gene expression, DNA damage response, and intracellular calcium signaling.
