NAD+: Research Background
Mechanism of Action: Nicotinamide adenine dinucleotide (NAD+) is an essential coenzyme in cellular metabolism, serving as an electron carrier in oxidative phosphorylation and as a substrate for sirtuin deacetylases and PARP enzymes involved in DNA repair and gene expression.
Research Applications: Sirtuin activation research, mitochondrial bioenergetics, DNA repair pathway studies, cellular aging and senescence research, and NAD+ bioavailability studies.
Published Research: Yoshino et al. on NAD+ and aging (Cell Metabolism, 2018). Rajman et al. ‘Therapeutic Potential of NAD-Boosting Molecules’ (Cell Metabolism, 2018). PubMed: ‘NAD+ aging sirtuin’.
Storage & Reconstitution
Storage: Store lyophilized NAD+ at -20°C away from light. Highly hygroscopic — use immediately after reconstitution.
Reconstitution Protocol: Add sterile/bacteriostatic water per vial specification. Use within 24 hours of reconstitution for best stability.
Quality Verification
Every batch of QSC NAD+ undergoes a full analytical testing protocol before shipment:
Mass Spectrometry (MS) — verifies molecular identity and sequence
Impurity Profiling — identifies and quantifies any trace impurities
Batch Traceability — every vial traceable to its published COA
Certificates of Analysis are published directly on the product page and independently verifiable via the Janoshik testing portal.
