Formulas Jarrowยฎ The vital vitamin B3 metabolite, NAD+, is effectively produced from the precursor nicotinamide mononucleotide (NMN). The synthesis of cellular energy and the operation of the mitochondria depend on NAD+. Aging and high calorie intake cause levels of NAD+ to drop, which can impair mitochondrial function. For sirtuins (SIRT), enzymes that control gene expression, DNA repair, mitochondrial biogenesis, and energy metabolism, NAD+ is a necessary cofactor.
