Pyridine dinucleotide coenzyme, sold for laboratory research.
Identity
NAD+ is not a peptide or a drug, it is a coenzyme, a helper molecule every living cell needs to run its energy-producing reactions. Cells build it from a B vitamin, and biologists have studied it for over a century because so much of metabolism runs through it. What is newer is interest in whether adding it back in from outside, by IV or otherwise, changes anything measurable.
NAD+ is a pyridine dinucleotide coenzyme, molecular formula C21H27N7O14P2, molecular weight 663.43 g/mol. SBz Industries sells it for laboratory research.
Research
In plain terms, with a link to every study. The most useful thing to notice is what each study was done in.
NAD+ itself, given directly rather than through a building-block molecule, has barely been tested in people, really just one small pilot study tracking where an infusion ends up in blood and urine. The much larger research base is on NAD+ biology in cells and animals, and on separate precursor molecules like nicotinamide riboside, which the body converts into NAD+ and which have their own human trials.

Ran a six-hour IV infusion of NAD+ itself in a small group of people and tracked NAD+ and its breakdown products in blood and urine throughout. Blood levels did not rise until after the first two hours, and the body cleared and processed the infused NAD+ fairly quickly.
A Pilot Study Investigating Changes in the Human Plasma and Urine NAD+ Metabolome During a 6 Hour Intravenous Infusion of NAD.
Grant and colleagues, Frontiers in Aging Neuroscience
review2021
Pulled together cell and animal studies on how NAD+ levels change with age and what cell processes depend on it, including DNA repair and energy metabolism. The authors say plainly that restoring NAD+ levels in aging people remains mostly untested territory, not an established practice.
NAD(+) metabolism and its roles in cellular processes during ageing.

people2020
Gave 13 adults six weeks of nicotinamide riboside, a related building-block molecule that raises NAD+ levels rather than NAD+ itself, followed by a placebo period, then took muscle biopsies and measured body composition and insulin response. Muscle NAD+ markers rose, but the researchers found no measured change in insulin sensitivity and only small shifts in body composition.
Nicotinamide riboside supplementation alters body composition and skeletal muscle acetylcarnitine concentrations in healthy obese humans.

Each study links to its record on PubMed, the US National Library of Medicine database. Checked 25 September 2026.
Handling
Lyophilized: -20C, protected from light. Reconstituted: 2-8C.
Give the vial twenty minutes on the bench before opening it, so water does not condense onto the powder.
Slowly, down the inside wall of the vial, never straight onto the powder.
Leave it alone until it clears. Do not shake it. Shaking damages the peptide.
Once mixed, it breaks down much faster than the dry powder. Keep it cold and dark.
Documentation
An independent lab tests every compound we sell. It confirms the compound is what the label says and measures purity by HPLC.
The latest certificate is on the product page, so you can read the result before you order.

One small pilot study gave people a six-hour IV infusion of NAD+ and tracked it in blood and urine. It measured where the NAD+ went, not what it changed in the body.
No. NMN and NR are separate molecules the body converts into NAD+; most of the human supplement research is actually on those precursors, not on NAD+ itself.
The molecular formula is C21H27N7O14P2. The molecular weight is 663.43 g/mol. Both are stated on the certificate of analysis on the product page.
NAD+ ships as a freeze-dried powder. Mix it with bacteriostatic water, added slowly down the inside wall of the vial, and let it dissolve without shaking. The researcher decides the working concentration, not us, and we publish no protocols.
Lyophilized: -20C, protected from light. Reconstituted: 2-8C. Vials ship in plain outer packaging with no product name on the outside.
Yes. An independent lab tests every compound: it confirms the compound is what the label says and measures purity by HPLC. The latest certificate is on the product page, and you can read it before you order.
Researchers and institutions, 21 or over. By ordering you confirm the material is for laboratory research and will not be used in humans or animals.
