Class
Pyridine nucleotide coenzyme
Half-life
Variable (rapid extracellular turnover)
Studied in
Mitochondrial bioenergetics, sirtuin/PARP signalling and ageing models.
What it is
NAD+ is a central pyridine nucleotide coenzyme used across redox biology, sirtuin signalling and PARP-mediated DNA repair pathways in ageing and metabolic research.
Mechanism studied
Essential coenzyme for redox reactions, sirtuin and PARP enzyme families.
Research notes
- Not a peptide; included for metabolic/longevity research completeness.
- Often studied alongside 5-Amino-1MQ and other NAD+-modulating tools.
Before sourcing any material
- Confirm a lot-matched third-party certificate of analysis (HPLC purity and mass-spectrometry identity).
- Check the stated peptide content per vial, not just the gross vial mass.
- Plan reconstitution volumes first so the vial size matches your protocol.
- Verify what is lawful in your jurisdiction — these are in-vitro research reagents, not medicines.
