NAD⁺ — Nicotinamide Adenine Dinucleotide
The master coenzyme behind cellular energy and healthy aging. NAD⁺ powers the reactions that keep every cell energized and is the essential cofactor for the sirtuins — the enzymes at the heart of longevity science. Its levels decline naturally with age, which is why NAD⁺ is one of the most studied molecules in the field. High-purity, research-grade, independently tested and COA-verified, made to Japan quality standards.

What is NAD⁺?
NAD⁺ (nicotinamide adenine dinucleotide, CAS 53-84-9) is a coenzyme found in every living cell — one of the most fundamental molecules in biology. It exists in two interchangeable forms, NAD⁺ and NADH, that cells continuously cycle between to carry electrons through the reactions of energy metabolism.
Beyond energy, NAD⁺ is consumed as a substrate by two important enzyme families: the sirtuins, studied in cellular maintenance and longevity signaling, and the PARPs, involved in DNA repair. Because cellular NAD⁺ levels are reported to decline with age, NAD⁺ biology has become one of the most active fields in metabolism and aging research. Aeternum Life supplies NAD⁺ as a high-purity, research-grade material, backed by a batch-specific Certificate of Analysis.
Research directions
NAD⁺ sits at the center of some of biology’s most important systems — energy, repair and longevity. Here is where it plays its role, and why it has become one of the most researched molecules in the field.
NAD⁺ is the electron carrier that drives ATP production — the energy currency of every cell. It sits at the center of glycolysis, the TCA cycle and oxidative phosphorylation, keeping mitochondria running.
NAD⁺ fuels the sirtuins (SIRT1–7) — the enzymes widely known as the “longevity genes” — which govern cellular maintenance, stress resistance and metabolic health.
The PARP enzymes draw on NAD⁺ to detect and repair DNA damage, tying NAD⁺ availability directly to the cell’s ability to protect its genome.
Cellular NAD⁺ falls steadily as we age — a decline that sits at the heart of modern longevity science and NAD⁺-restoration research.
Through its NAD⁺-dependent enzymes, NAD⁺ helps orchestrate how cells handle glucose and fat, making it a cornerstone of metabolic research.
Neurons are energy-hungry, and NAD⁺ metabolism is a growing focus in research on brain energy, resilience and healthy aging.

Frequently asked questions
What is NAD⁺ studied for?
In the research literature NAD⁺ is studied mainly in relation to cellular energy metabolism, the sirtuin and PARP enzymes, DNA repair and aging. Aeternum Life shares these only as areas of research interest, not as claims of any effect.
Do NAD⁺ levels change with age?
Research across many models reports that tissue NAD⁺ levels tend to decline with age, which is a central question in NAD⁺ metabolism research. This is background biology, not a claim about any product effect.
Is NAD⁺ for human use?
No. Aeternum Life supplies NAD⁺ strictly as a research-grade material for laboratory research. It is not sold for human or veterinary consumption.
Is a COA available for NAD⁺?
Yes — every NAD⁺ batch ships with a batch-specific Certificate of Analysis covering identity and purity.
