NAD+
Nicotinamide adenine dinucleotide
A ubiquitous redox coenzyme central to cellular energy metabolism and a substrate for enzymes such as sirtuins and PARPs; it is a coenzyme, not a peptide. Studied in aging, metabolic, and neurological research; cellular levels reportedly decline with age.
Half-life
Intracellular turnover ~1-4 h (compartment-dependent); a single plasma half-life is not well defined. Half-life is an educational pharmacology figure, drawn from public sources, and is not a schedule or dosing instruction.
Storage & handling
Sensitive to heat, light, and moisture; injectable forms kept refrigerated or frozen and protected from light; reconstituted solutions used within a limited window.
