NAD+
NAD+ is a helper molecule (a coenzyme) your cells cannot make energy without. It carries electrons during metabolism. It is also the fuel for three groups of enzymes: sirtuins, PARPs, and CD38. Here is the problem. Your NAD+ drops sharply as you age, in nearly every tissue. That weakens mitochondria, DNA repair, and sirtuin activity. So researchers test precursors your body converts into NAD+, like NR and NMN, to top tissues back up. The results so far are mixed. (NAD+ stands for nicotinamide adenine dinucleotide; NR is nicotinamide riboside, NMN is nicotinamide mononucleotide.)
