NAD+: Research Profile, Dosages & Supplier Prices
NAD+ is a cofactor / longevity research compound with a molecular weight of 663.4 g/mol and a research half-life of short plasma half-life; intracellular turnover studied in hours. NAD+ is a coenzyme (technically a dinucleotide, not a peptide) central to cellular energy metabolism and sirtuin signaling. It is sold by many peptide suppliers because of overlapping research demand in longevity science.

| Half-life | Short plasma half-life; intracellular turnover studied in hours |
| Forms sold | Lyophilized vial |
What is NAD+?
Published research covers age-related NAD+ decline, sirtuin and PARP pathway studies, and mitochondrial function models. Most human research has focused on precursors (NMN, NR) because of NAD+ bioavailability questions, but direct NAD+ administration is studied in research settings.
Quality note: NAD+ is heat and pH sensitive. Proper cold-chain handling and recent synthesis dates matter more than for stable peptides.
Mechanism of Action (Research Context)
Essential redox cofactor and substrate for sirtuins, PARPs, and CD38 - studied for cellular energy metabolism and DNA repair signaling.
Research Areas
NAD+ Dosages in Research
Published research used a wide range of doses depending on route. Laboratory research use only.
Dosage information is a summary of published laboratory research and is provided for informational purposes only. These compounds are not for human use.
Storage & Handling
Lyophilized: -20C, protect from light and moisture. Reconstituted: 2-8C, use promptly - NAD+ degrades faster than typical peptides.
