NAD+
Critical coenzyme studied for energy metabolism, DNA repair, sirtuin activation, and cellular longevity.
Molecular reference
Research background
NAD+ (Nicotinamide Adenine Dinucleotide) is a critical coenzyme found in all living cells, central to energy metabolism and cellular repair mechanisms. Research interest in NAD+ has grown due to its role in activating sirtuins, supporting DNA repair, and regulating the circadian clock.
Studies have investigated its role in mitochondrial function, neuroprotection, and the biology of ageing. Preclinical models have shown promising results in restoration of NAD+ levels in aged tissues.

Reconstitution
- Supplied as a lyophilized (freeze-dried) powder for laboratory reconstitution.
- Bacteriostatic water (0.9% benzyl alcohol) is the most common reconstitution solvent for multi-use research handling; sterile or acetic-acid solutions are used for specific compounds.
- Introduce solvent slowly against the vial wall rather than directly onto the powder, and allow it to dissolve without vigorous shaking.
- Use the reconstitution calculator to determine solvent volume for a target concentration in your protocol.
Storage & handling
- Lyophilized powder: store sealed at -20 °C for long-term stability; short periods at 2–8 °C are generally acceptable.
- Once reconstituted: refrigerate at 2–8 °C and protect from light; use within the compound-specific window noted on the COA.
- Avoid repeated freeze–thaw cycles of reconstituted solution.
- Keep away from direct light and heat at all times.
Purity & verification
Every Popular Peptides batch is third-party tested by HPLC and LC-MS with a published Certificate of Analysis (≥99% purity).
