Nicotinamide Adenine Dinucleotide (NAD+) 500mg
Original price was: $135.00.$94.50Current price is: $94.50.
NAD+ is a central cellular coenzyme that connects redox chemistry, energy metabolism, and NAD-dependent enzyme activity. As oxidized nicotinamide adenine dinucleotide, it participates in the molecular reactions researchers use to investigate cellular energy pathways. Its role across interconnected metabolic processes makes NAD+ a foundational research material for exploring cellular function and biochemical regulation.

⚠️ Important Disclaimer
Research purposes only. Not for human consumption or therapeutic treatment.
NAD+ is a coenzyme, not a peptide. Think of it as part of the cell’s electron-transfer system: it participates in reactions that connect nutrient processing with energy metabolism. It is also used by several enzyme families studied in cellular regulation.
What researchers investigate
- NAD+/NADH balance: Study the balance between oxidized and reduced forms as a measure of cellular redox conditions.
- Enzyme activity: Investigate NAD-dependent enzymes, including sirtuins and PARPs.
- Cellular metabolism: Examine biochemical reactions involved in energy processing and stress responses.
What makes it different?
NAD+ is the oxidized coenzyme. It is not NADH, NMN or NR, and those materials should not be treated as interchangeable.
Research findings describe the materials and conditions studied; they do not predict results in people.

What the results mean
- Identity: checks whether the tested sample matches the reported compound.
- Purity: measures the chromatographic purity reported by the method; it is different from milligrams in a vial.
- Content: reports how much material was measured in the tested sample.
A certificate documents the tested sample and the tests shown. It does not establish clinical effectiveness or regulatory approval. Purity testing is not a sterility test.
Handling & Storage
Good handling protects the integrity of your research sample. Use the product label, any matching technical documentation and your laboratory’s approved procedure for this exact material.
- Check before opening: confirm the compound, vial size and relevant report.
- Keep dry material protected: minimize unnecessary exposure to moisture, light and temperature changes; follow the storage instructions supplied with your vial.
- Choose the solvent for the material: solubility and stability vary. Water, saline, PBS and acidic solutions are not automatically interchangeable.
- Label prepared samples: record the contents, concentration, preparation date and validated storage period. Use aliquots where appropriate to reduce repeated handling.
There is no universal reconstitution volume or shelf life for every peptide. A clear solution alone does not confirm identity, stability or sterility.
FAQ
What is the labeled amount?
500 mg per vial. For a blend, this is the total of the listed components. A concentration is calculated only after the final solution volume is known.
Where can I check the testing?
The Certificate of Analysis tab displays COA8276 from Bioviridian Inc. Open the full-size image and use the lab’s verification page to check the report. Confirm the sample size and how the report relates to your vial.
Is purity the same as the amount in the vial?
No. Purity is a measurement made by an analytical method; content is the measured amount of material. A high purity percentage does not, by itself, tell you how many milligrams are present.
How should I interpret the research?
A role in normal cell biology does not establish that this research product improves energy, aging or health in people.
