Nicotinamide adenine dinucleotide (NAD+) plays a critical role in redox reactions, sirtuin activation, and DNA repair pathways. Declining NAD+ levels with age have made it a subject of extensive aging-biology research.
Most published studies focus on precursor molecules — nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) — and their ability to elevate intracellular NAD+ pools.
When designing a research protocol, consider baseline NAD+ measurement methodology, dosing frequency, and route of administration. Subcutaneous research in animal models has produced different pharmacokinetic profiles than oral precursor supplementation.
