NAD+: A Research Overview

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell and central to energy metabolism. It is a major focus of research on cellular aging and mitochondrial function. Material sold here is a research-use-only compound — not for human use.

• What it is: a coenzyme for redox reactions, not a peptide.
• Why it matters: a cofactor for sirtuins, PARPs and CD38 — enzymes tied to metabolism and DNA repair.
• Research theme: NAD+ levels decline with age in many model organisms.
• Status: sold as research-grade material for laboratory use only.

What is NAD+?

NAD+ is one of the most fundamental molecules in cellular biology. It shuttles electrons during the redox reactions that produce cellular energy, and it serves as a required cofactor for several enzyme families. Because of this dual role, it appears across a wide range of metabolic research.

What researchers study

NAD+ research spans cell-based and animal models examining how the molecule influences core cellular processes:

• Energy metabolism — NAD+ as an electron carrier in cellular respiration.
• Sirtuin activity — NAD+-dependent enzymes involved in metabolic regulation.
• DNA repair — PARP enzymes consume NAD+ during repair processes.
• Aging models — the observed decline of NAD+ levels over time.

Storage & handling

NAD+ is supplied lyophilized. Keep it cold and protected from light, reconstitute only when needed for research, and limit freeze–thaw cycles to preserve integrity. See our guide on reconstituting lyophilized materials.
