NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of your body that plays a key role in releasing energy. Researchers follow it mainly because natural NAD+ levels fall as you age, hence the attention in longevity and mitochondrial research. At GradePurity you buy NAD+ as a research-grade vial: ≥99% HPLC purity and same-day shipping from the Netherlands. It's strictly a research material for the lab, not a dietary supplement or infusion.
What does NAD+ do?
NAD+ is the molecule your cells use to release energy from food, without NAD+, the cell's power plant grinds to a halt. It's also the "fuel" for a group of enzymes (the sirtuins) involved in cell maintenance and DNA repair. Precisely because the natural NAD+ supply declines over the years, researchers look at it in the context of ageing and energy. At GradePurity you buy it purely as a research material, not for use in humans.
How does NAD+ work?
NAD+ acts like a shuttle for electrons: it switches between two forms (NAD+ and NADH) and so carries the energy your mitochondria turn into ATP. In that same role it's a co-substrate for sirtuins and other repair enzymes, which is why it shows up so often in ageing research. Most of what's known comes from cell and animal studies.
NAD+ and ageing
The reason NAD+ gets so much attention is simple: in nearly every tissue the NAD+ level drops as we age, and researchers link that to less cellular energy and slower recovery. So the lab question is whether topping up or sparing NAD+ can offset that decline. This is thought to be where the "longevity" link comes from. We make no health claims about it ourselves, at GradePurity NAD+ is a research material.
NAD+ vs NMN and NR
This is where many people lose the thread. NMN and NR (nicotinamide riboside) aren't NAD+ itself but precursors: building blocks the body converts into NAD+. NAD+ is the end product, the coenzyme actually used in the reactions. In research the precursors are often used because cells take them up more easily; direct NAD+ is of interest when you want to study the end molecule. GradePurity supplies NAD+ as a research-grade vial; we don't carry NMN or NR.
NAD+ as a research vial, not a capsule or infusion
Important to know before you order: what we sell is a research-grade NAD+ vial for laboratory use, not a capsule, cream or IV infusion. The NAD+ capsules and infusions you see in pharmacies or clinics are consumer products with a different purpose and dose. Our vial is meant for researchers who want to work with the pure coenzyme.
Side effects and safety
Because NAD+ occurs naturally in the body, as a material it's known for a mild profile; for precursors like NMN/NR, studies usually report few or mild effects. With rapid delivery (such as infusions, outside our scope) brief reactions like flushing or a feeling of pressure are sometimes described. Large long-term data in humans is still lacking.
Purity & lab testing
With a coenzyme like NAD+, purity matters all the more because it's sensitive to moisture and degradation. That's why we test every batch by HPLC for ≥99% purity and for identity, and ship it freeze-dried so it reaches you stable. So you know exactly what you're holding, the exact specifications are in the table at the bottom of this page.
