NAD+ (Nicotinamide Adenine Dinucleotide) is a critical coenzyme present in all living cells, extensively studied for its role in cellular energy metabolism and mitochondrial function. As a key electron carrier, NAD+ is essential in redox reactions that drive ATP production and support overall cellular activity.
In research settings, NAD+ has been widely explored for its involvement in metabolic pathways, DNA repair mechanisms, and cellular signaling processes. It also plays a significant role in the activation of sirtuins—proteins associated with cellular regulation, stress response, and longevity-related pathways.
Declining NAD+ levels have been observed in aging models, making it a compound of growing interest in studies focused on cellular aging, metabolic efficiency, and mitochondrial health. Its broad biological relevance has positioned NAD+ as a foundational molecule in a wide range of in vitro and preclinical research applications.
