NAD+

Nicotinamide Adenine Dinucleotide (NAD+) is an essential coenzyme found in all living cells, playing a critical role in cellular metabolism and energy production. It functions primarily as an electron carrier in redox reactions and serves as a vital substrate for enzymes such as sirtuins and poly (ADP-ribose) polymerases (PARPs), which are involved in DNA repair and gene expression. Research into NAD+ focuses on its potential to support mitochondrial function, counteract age-related cellular decline, and facilitate cellular resilience.
