Essential Cellular Coenzyme

The Foundation of Cellular Energy and Repair Research

NAD+ (Nicotinamide Adenine Dinucleotide) is a critical coenzyme involved in over 500 enzymatic reactions throughout the body. Central to cellular energy metabolism, DNA repair, and mitochondrial function, NAD+ has become essential for researchers investigating aging, metabolic health, and cellular resilience. Its levels naturally decline with age, making it a key target for longevity research.

  • Essential coenzyme for 500+ enzymatic reactions
  • Central role in glycolysis, TCA cycle, and oxidative phosphorylation
  • Critical for DNA repair and genomic stability
  • Supports mitochondrial biogenesis and function
  • High purity (≥98%) for reliable research outcomes
Cellular Mechanisms

How NAD+ Powers Cellular Function and Repair

NAD+ functions as an electron carrier in redox reactions, shuttling electrons through the metabolic pathways that generate ATP — the cell's energy currency. Beyond energy production, NAD+ serves as a substrate for sirtuins (longevity-associated enzymes), PARPs (DNA repair enzymes), and CD38 (immune signaling). This multi-pathway involvement makes NAD+ central to cellular health research.

  • Electron carrier for ATP production pathways
  • Substrate for sirtuins (SIRT1-7) — key longevity enzymes
  • Required for PARP-mediated DNA repair
  • Modulates CD38 and immune cell signaling
  • Supports circadian rhythm regulation
Research Applications

From Aging Biology to Metabolic Research — Expanding Frontiers

NAD+ has emerged as a cornerstone of longevity and metabolic research. Scientists use it to investigate age-related cellular decline, mitochondrial dysfunction, and metabolic disorders. Its role in sirtuin activation and DNA repair makes it essential for studies exploring healthspan extension, neuroprotection, and cellular rejuvenation.

  • Aging biology and longevity pathway studies
  • Mitochondrial function and bioenergetics research
  • DNA damage response and genomic stability
  • Metabolic health and insulin sensitivity modeling
  • Neuroprotection and cognitive function studies
  • Sirtuin activation and caloric restriction mimetics
