ACSH Explains: Nicotinamide adenine dinucleotide (NAD)

Watch me get an NAD injection! NAD, which stands for nicotinamide adenine dinucleotide, is a coenzyme found in all living cells that’s essential for countless biological processes. 🧬 It exists in two forms: NAD (the oxidized form) and NADH (the reduced form). NAD’s main job is to act like a shuttle bus, carrying electrons and hydrogen atoms from one molecule to another during metabolic reactions. This is a process known as a redox reaction. NAD is a key player in cellular respiration, the proce
