NAD+ dissolves readily — the solution will appear slightly yellow-orange, which is normal for the nicotinamide adenine dinucleotide chromophore. Do not shake vigorously.”}}, {“@type”: “Question”, “name”: “How should NAD+ be stored?”, “acceptedAnswer”: {“@type”: “Answer”, “text”: “Store lyophilized at −20°C, protected from light. NAD+ is sensitive to light and heat — the ribose ring can hydrolyse under acidic or high-temperature conditions. Reconstituted: use within 7–14 days refrigerated, ideally fresh-prepared.”}}, {“@type”: “Question”, “name”: “What purity is QSC NAD+ and how is it verified?”, “acceptedAnswer”: {“@type”: “Answer”, “text”: “QSC NAD+ is ≥99% pure by HPLC on every batch, with identity confirmed by mass spectrometry.

What is NAD+?
NAD+ (Nicotinamide Adenine Dinucleotide — essential cellular coenzyme) is a Dinucleotide coenzyme (C₂₁H₂₇N₇O₁₄P₂). Essential redox coenzyme in oxidative phosphorylation (NADH/NAD+ cycling in ETC), substrate for all 7 sirtuins (SIRT1-7 deacylases), substrate for PARPs (DNA strand break repair), and CD38/cyclic ADP-ribose signalling. Declines 40–60% in most tissues with ageing.
Research Applications
Sirtuin Activation
SIRT1-7 NAD+-dependent deacylase activity, PGC-1α, FOXO3a
Mitochondrial Function
ETC complex I substrate cycling, ATP synthesis efficiency
DNA Repair
PARP1/2 activation — single-strand break repair and genome stability
NAD+ Decline Biology
Age-related NAD+ loss mechanisms — CD38, PARPs, sirtuins
vs NMN/NR
Direct NAD+ vs precursor supplementation — bioavailability comparison
