NAD+ Coenzyme

Meaning

NAD+ Coenzyme, or Nicotinamide Adenine Dinucleotide, is a critical molecule found in every cell, functioning as a vital coenzyme essential for thousands of enzymatic reactions. It exists in two primary forms: the oxidized form (NAD+) and the reduced form (NADH). NAD+ is fundamental to cellular energy production, serving as a critical electron acceptor in the metabolic pathways of the mitochondria. Furthermore, it acts as a necessary substrate for sirtuins and PARPs, enzymes central to DNA repair, gene expression, and cellular longevity. Maintaining optimal NAD+ levels is a key objective in metabolic and anti-aging medicine.
