About NAD+

NAD+ (nicotinamide adenine dinucleotide) is a small-molecule coenzyme, not a peptide. It participates in cellular oxidation-reduction reactions and serves as a substrate for enzymes including PARPs and sirtuins, which link it to metabolism and cellular maintenance. Research reports age-associated changes in NAD+ across tissues, but the size and significance vary by tissue and method. Evidence that changing NAD+ availability improves meaningful human health outcomes remains much less settled than its basic biochemical role.

At a glance

Class: Endogenous dinucleotide coenzyme; not a peptide or a peptide precursor.
Studied mechanism: Transfers reducing equivalents in metabolism and is consumed by enzymes such as PARPs and sirtuins.
Evidence context: Cellular and animal work supports important biochemical functions; human intervention findings do not establish broad longevity benefits.

Blank arithmetic calculator

For independently verified inputs, concentration equals entered vial amount in mg divided by added liquid in mL. Entered requested mg divided by concentration gives mL; multiplying mL by the actual syringe markings per mL gives units. Enable JavaScript to use the calculator. This math does not establish that a compound is suitable for injection.

Common questions

Is NAD+ a peptide?

No. NAD+ is a dinucleotide coenzyme made from nicotinamide and adenine-containing components; it is chemically distinct from peptides.

Does age-related NAD+ decline prove that raising it extends human lifespan?

No. Reviews describe age-associated NAD+ changes, but human evidence that interventions meaningfully extend lifespan or improve broad health outcomes is not established.
