NAD+
NAD+ is a coenzyme essential to cellular energy production, DNA repair, and sirtuin activation. Central to longevity and aging research.
What Is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell, essential for hundreds of metabolic reactions. It plays a critical role in mitochondrial energy production, DNA repair via PARP enzymes, and sirtuin activation—a family of proteins linked to cellular aging and longevity. Research published in Cell, Nature, and Science has documented the decline of NAD+ levels with age.
History
NAD+ was first discovered in 1906 by Arthur Harden and William John Young during research into fermentation. Its structure was determined by Hans von Euler-Chelpin in the 1930s, work for which he received the Nobel Prize. The modern era of NAD+ research began in the early 2000s when Dr. Leonard Guarente and Dr. Shin-ichiro Imai at MIT identified the connection between NAD+ and sirtuin enzymes. Dr. David Sinclair’s research at Harvard further established the link between age-related NAD+ decline and cellular aging, sparking a wave of translational research that continues today.
Certificate of Analysis (COA)
Every batch of our peptides is independently tested by third-party laboratories to verify purity, identity, and potency. We maintain 98%+ purity standards across our entire product catalog.
Reconstitution & Storage
Reconstitute with bacteriostatic water (BAC water). Using a sterile syringe, slowly inject 1-2mL of BAC water into the vial, directing the stream against the glass wall. Do not inject directly onto the lyophilized powder. Gently swirl until fully dissolved. Do not shake.
Store unreconstituted vials at room temperature away from direct sunlight. After reconstitution, store at 2-8°C (standard refrigerator). Use within 30 days of reconstitution. Do not freeze.

Frequently Asked Questions
What is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme in every living cell for hundreds of metabolic reactions. Critical for mitochondrial energy, DNA repair via PARP, and sirtuin activation. Declines with age per published research in Cell, Nature, Science.
What is NAD+ supplement?
NAD+ supplementation research focuses on restoring declining cellular levels. Protocol Aminos offers NAD+ in liquid form for research, not as a dietary supplement. 500mg ($79) and 1000mg ($129).
What is the difference between NAD+ and NMN?
NAD+ is the active coenzyme; NMN is a precursor the body converts to NAD+. Protocol Aminos supplies NAD+ directly for researchers working with the active compound.
How is NAD+ used in research?
NAD+ is actively studied in clinical research settings. Protocol Aminos sells NAD+ for laboratory use only, not for human use or consumption.
What is NAD+ used for in research?
Mitochondrial function, sirtuin activation, DNA repair, neurodegenerative disease models, and age-related metabolic decline.
Does the product come with instructions?
Each order includes product documentation with storage requirements and handling guidelines. Sold for research purposes only.
What's the actual amount in each vial?
Each vial contains the labeled amount of NAD+ in liquid form. The exact quantity is verified via third-party testing and documented on the batch-specific Certificate of Analysis.
Are additional supplies needed?
No. All Protocol Aminos products ship in liquid form, ready for immediate research use. No additional preparation, mixing, or supplies required.
How long does a vial last?
Shelf life depends on storage conditions. Store refrigerated at 2–8°C, away from direct light, and keep sealed when not in use. Specific stability data is available on request.
