That molecule is nicotinamide adenine dinucleotide, commonly called NAD+, which acts as a lead molecule driving cellular energy production, DNA repair, and mitochondrial function. Yet researchers have found that NAD levels drop by 50-70% in human tissues by middle age—and a single enzyme called CD38 is a significant contributor to this decline.</p>
