NAD+

Each vial of NAD+ 500 mg from PrimeTime BioLabs contains 500 mg of nicotinamide adenine dinucleotide supplied as a sterile lyophilized powder. The material ships in a light-protected vial labeled with its batch number for traceability, alongside reconstitution and storage guidance written for laboratory research use. Every batch is matched to a downloadable Certificate of Analysis so researchers can confirm the purity and identity profile of the specific lot they receive before it enters their protocol.

NAD+ is the oxidized form of nicotinamide adenine dinucleotide, a dinucleotide coenzyme built from an adenine-containing nucleotide and a nicotinamide-containing nucleotide joined through a shared phosphate backbone. It is not a peptide — its structure and function are entirely distinct from amino-acid chains. In cellular biochemistry, NAD+ cycles with its reduced counterpart, NADH, to shuttle electrons through oxidative metabolism, and it also serves as a required co-substrate for enzyme families including sirtuins and PARPs (poly-ADP-ribose polymerases). This dual role — as a redox carrier and as an enzyme co-substrate — is why NAD+ is a recurring subject in laboratory research on mitochondrial function, cellular energy metabolism, sirtuin biology, and DNA-repair-associated enzymatic pathways. These are areas of active biochemical and preclinical investigation. PrimeTime BioLabs supplies NAD+ 500 mg to support that research; the material is not evaluated for, and makes no claims regarding, any effect in humans or animals.

NAD+ 500 mg is manufactured under controlled conditions and independently verified via HPLC and mass spectrometry prior to release, with each production batch sent to a third-party lab for analysis. The batch-specific Certificate of Analysis lists the lot number, measured purity, and analysis date for the exact vial a researcher receives. It's worth being precise about what this documentation does and doesn't establish. HPLC and mass spectrometry results describe the chromatographic and mass profile of the tested sample — they support an assessment of purity and chemical identity under the stated method, for the specific batch tested. They do not constitute proof of sterility, endotoxin status, clinical safety, or biological effect, and a purity figure is not a substitute for a researcher's own protocol-specific verification. Current batch on file: PTB-NAD-500MG-0925 — 99% purity — analyzed 8/27/2026.
