Overview
NAD+ (nicotinamide adenine dinucleotide) is a central redox cofactor studied for cellular energy, DNA repair, and sirtuin activation in aging research. Injectable and IV formulations in research settings differ from oral precursors (NMN/NR) in bioavailability studies. Essential redox cofactor — not a peptide but cataloged for NAD+ pathway research completeness.

- Nicotinamide adenine dinucleotide coenzyme
Mechanism
Essential redox cofactor for sirtuins, PARPs, and mitochondrial oxidative phosphorylation. Sirtuin and PARP activities depend on NAD+ pool availability in aging biomarker studies.

Stability & storage phases
| Phase | Condition | Guidance |
|---|---|---|
| Lyophilized / powder | Refrigerated (2–8 °C), protected from light and humidity | NAD+ is redox-active and moisture-sensitive; sealed cold storage preserves cofactor integrity per published protein stability data. |
| Reconstituted | pH-buffered sterile solution, refrigerated | Maintain near-neutral pH; acidic or alkaline excursions accelerate degradation — verify buffer specification before mixing. |
| Working aliquots | Frozen (−20 °C) in opaque tubes, minimal headspace | Prepare small aliquots and limit light exposure during thaw; oxidative loss increases with temperature and repeated handling. |
Stability windows are formulation-dependent — verify published data and your lab SOP.

Reconstitution steps
- Allow vial to reach room temperature (15–30 min)
- Swab rubber stopper with alcohol prep pad
- Draw calculated bacteriostatic water into syringe
- Inject diluent slowly down vial wall — do not spray directly onto cake
- Gently swirl until fully dissolved — do not shake vigorously
- Label with date, concentration, and diluent volume
- Refrigerate and use within your lab stability window
Often supplied as lyophilized powder; diluent and pH vary by formulation.
