NAD+ (Nicotinamide Adenine Dinucleotide) is a crucial coenzyme found in every living cell that plays a central role in numerous biological processes, including cellular energy production, DNA repair, gene expression, and cellular defense mechanisms. NAD+ acts as a key molecule in redox reactions, facilitating the transfer of electrons and promoting the conversion of nutrients into energy (ATP) through metabolic pathways like glycolysis, the Krebs cycle, and oxidative phosphorylation.
As people age, levels of NAD+ in the body naturally decline. This decrease in NAD+ is associated with several age-related health issues, including reduced energy production, impaired DNA repair, increased oxidative stress, and metabolic disorders. Restoration of NAD+ levels has been shown to promote better health in aging individuals by improving energy metabolism, DNA repair, and cellular resilience. Increasing NAD+ levels is also thought to activate sirtuins, which enhance mitochondrial function and extend healthy lifespan.
