NAD+ 500mg

NAD+ (nicotinamide adenine dinucleotide, oxidized form) is a ubiquitous coenzyme present in all living cells and essential for over 500 enzymatic reactions. It serves as a critical electron carrier in mitochondrial oxidative phosphorylation, a substrate for sirtuins (SIRT1–SIRT7) and poly(ADP-ribose) polymerases (PARPs), and a precursor for the calcium-mobilizing second messenger cyclic ADP-ribose. Cellular NAD+ levels decline with age, and extensive research has investigated the implications of this decline on metabolic function, genomic stability, and circadian rhythm regulation. Our NAD+ is produced through enzymatic synthesis, achieving high purity with minimal degradation products, and is supplied in lyophilized form for maximum stability.
