NAD+
What is it?
NAD+ is the oxidised form of nicotinamide adenine dinucleotide, a coenzyme rather than a peptide. It is present in living cells and participates in multiple biochemical processes. NAD+ and its reduced form NADH have related but distinct chemical states.
How it is studied
NAD+/NADH reactions transfer electrons during metabolism. NAD+ also participates in reactions used by other cellular enzymes. A normal role in energy metabolism does not mean that additional externally supplied NAD+ necessarily reaches the relevant intracellular compartment or changes a desired outcome.
What the evidence shows
Chemical reference information establishes identity and biochemical context. It does not demonstrate that administering a research vial improves fatigue, cognition, ageing or exercise performance. Delivery, cellular uptake and formulation are separate research questions.
Limitations & safety context
The listed mass does not specify salt form, water content, purity or stability. NAD+ is not interchangeable with NADH or with precursors such as nicotinamide. A biochemical pathway should not be presented as a clinical benefit from an independently supplied preparation.
