NAD+

NAD⁺ – Core Redox Coenzyme for Metabolism and Longevity Research

NAD⁺ (nicotinamide adenine dinucleotide, oxidized form) is an essential pyridine nucleotide that shuttles electrons in metabolic pathways, coupling nutrient oxidation to ATP production in glycolysis, the TCA cycle, and oxidative phosphorylation. Beyond its metabolic role, this central cofactor serves as a substrate for sirtuins, PARPs, and CD38, linking cellular energy status to DNA repair, chromatin remodeling, inflammatory signaling, and pathways relevant to aging and tissue regeneration.

Key features

• Master redox carrier: NAD⁺/NADH cycling drives electron transfer for ATP generation, with changes in NAD⁺ availability directly affecting mitochondrial function, mitophagy, and cellular resilience to energetic stress.

• DNA repair and genomic stability: NAD⁺ fuels PARP‑dependent DNA repair and sirtuin‑mediated deacetylation, processes that help maintain genome integrity and modulate cellular senescence and stress responses.

• Aging and metabolic health: Declines in tissue NAD⁺ with age are associated with impaired metabolism, mitochondrial dysfunction, inflammation, and multiple age‑related disorders, making NAD⁺ restoration a major focus in preclinical longevity research.

• Regenerative and organ‑protection relevance: In animal models, raising NAD⁺ has been linked to improved cardiovascular, muscular, neurologic, and renal function, along with enhanced stem‑cell performance and repair capacity after injury.

  
  

Research applications

NAD⁺ (and its boosting strategies) is used in experimental systems exploring:

• Metabolism and mitochondrial biology, including insulin resistance, obesity, fatty‑liver disease, and mitochondrial myopathies.

• Neurodegeneration and cognition, where NAD⁺ pathways are studied in models of Alzheimer’s, Parkinson’s, and other neurodegenerative conditions.

• Cardiovascular and muscle function, assessing exercise capacity, cardiac remodeling, skeletal‑muscle endurance, and recovery.

• Systemic aging and immunometabolism, examining how NAD⁺ influences inflammation, immune‑cell function, cellular senescence, and healthspan.

  
  

Recommended handling

• For controlled laboratory research use only, by qualified professionals.

• Store in a cool, dry environment away from light and moisture; follow institutional SOPs for handling labile nucleotides, solution preparation, and disposal.

• Investigators should consult current literature for dosing, route of administration, and appropriate biomarkers (e.g., whole‑blood or tissue NAD⁺ levels, NAD⁺/NADH ratio, downstream sirtuin/PARP activity).
