Science

NAD+ (Nicotinamide Adenine Dinucleotide) has become a focus of groundbreaking research in health, aging, and disease prevention. Below, we explore the key scientific studies that highlight its importance, along with a glossary of technical terms to simplify complex concepts.

Key Scientific Studies

  1. NAD+ and Aging

    • Study: A landmark study published in Cell Metabolism demonstrated that declining NAD+ levels contribute to age-related metabolic decline. Researchers found that supplementing with NAD+ precursors like NMN restored mitochondrial function and improved physical activity in aged mice.
    • Key Finding: NAD+ supplementation reversed some aging markers and enhanced energy metabolism.

  2. NAD+ in DNA Repair

    • Study: Research in Nature Communications showed that NAD+ activates PARP enzymes, which repair DNA damage caused by aging, stress, and environmental toxins.
    • Key Finding: Increasing NAD+ levels enhanced the body’s ability to repair damaged DNA and maintain genomic stability.

  3. NAD+ and Neuroprotection

    • Study: A study published in Neuron found that NAD+ protects neurons from degeneration and supports brain health by reducing oxidative stress and inflammation.
    • Key Finding: Boosting NAD+ levels slowed cognitive decline in models of Alzheimer’s disease.

  4. NAD+ and Metabolic Health

      • Study: Research in Science highlighted NAD+’s role in regulating metabolic pathways, showing that restoring NAD+ levels improved insulin sensitivity and reduced obesity in animal models.
      • Key Finding: NAD+ is critical for metabolic health and preventing chronic conditions like diabetes.

Glossary of Technical Terms

  • NAD+ (Nicotinamide Adenine Dinucleotide): A coenzyme essential for energy production, DNA repair, and cellular processes.
  • Coenzyme: A molecule that assists enzymes in facilitating biochemical reactions.
  • Mitochondria: The “powerhouses” of cells that generate energy.
  • Sirtuins: Proteins activated by NAD+ that regulate aging, stress response, and cellular health.
  • PARPs (Poly ADP-Ribose Polymerases): Enzymes involved in DNA repair.
  • Oxidative Stress: Damage caused by an imbalance between free radicals and antioxidants in the body.
  • Neuroprotection: Processes that preserve the structure and function of neurons in the brain.
  • NMN (Nicotinamide Mononucleotide): A precursor to NAD+ used in supplementation to boost NAD+ levels.
