NAD+ 1000MG | Cellular Energy & Anti-Aging

NAD+ 1000mg is a research-grade nicotinamide adenine dinucleotide coenzyme studied for redox homeostasis, sirtuin signalling, DNA repair and mitochondrial function. This 3 ml vial containing 1000 mg presentation is intended for laboratory investigation of high-mass NAD+ supplementation in long protocols. NAD+ sits at the centre of cellular redox chemistry and is consumed by sirtuins, PARPs and CD38. Its availability influences histone deacetylation, DNA-damage repair, calcium signalling and mitochondrial biogenesis. The 1000 mg presentation is intended for studies that require larger molar amounts or extended treatment schedules.

Verdin (Science, 2015) described NAD+ as a nodal regulator of metabolism and ageing, while Belenky and colleagues (Trends in Biochemical Sciences, 2007) detailed the pathways that maintain NAD+ pools. Subsequent work has tested NAD+ repletion in models of neurodegeneration, metabolic disease and mitochondrial myopathy. The 1000 mg vial supports multi-arm studies, perfusion experiments and protocols that compare NAD+ with precursors or inhibitors of NAD+ consumption. Researchers measure NAD+ and NADH, sirtuin activity, PARP activation and mitochondrial respiration.

Because the vial contains a large molar quantity, prepare working aliquots immediately after reconstitution and avoid storing the entire solution as a single stock. Use mass spectrometry or enzymatic cycling assays to confirm concentration, since NAD+ degrades with repeated temperature fluctuations. Store the lyophilised powder at -20C, protect it from light, and reconstitute with bacteriostatic water or an appropriate laboratory buffer according to institutional protocols. Prepare aliquots before freezing and avoid repeated freeze-thaw cycles, which degrade peptide structure and reduce reproducibility.

Key questions concern tissue-specific NAD+ uptake, the balance between beneficial sirtuin activation and pro-inflammatory NAD+ consumption, and whether high-mass supplementation saturates salvage pathways.
