NAD+ (Nicotinamide Adenine Dinucleotide) is a crucial coenzyme present in every living cell, playing an essential role in energy metabolism, DNA repair, and cellular health. It is involved in hundreds of biochemical reactions that convert nutrients into usable energy and support vital cellular functions. NAD+ functions as a key electron carrier in metabolic processes, especially in the mitochondria, where it helps transform food into adenosine triphosphate (ATP)—the main energy currency of the cell. It also activates enzymes called sirtuins, which regulate aging, inflammation, and stress resistance.

NAD+ supplementation is an emerging area in health science with ongoing research supporting its potential benefits in energy, aging, and cellular health.
