What is NAD?

Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in every cell. It plays a vital role in energy production, DNA repair, and cellular maintenance. NAD exists in two forms: NAD+ and NADH.

Energy Production

NAD+ converts to NADH in the mitochondria. NADH then donates electrons to the electron transport chain, producing ATP — body’s main energy source.
DNA Repair

NAD+ fuels PARP enzymes, which detect and repair DNA damage, preserving cellular function.
Cell Regeneration

NAD+ activates proteins called sirtuins that regulate metabolism, promote mitochondrial regeneration, and support healthy aging.
Oxidative Stress

NAD+ helps regulate redox balance and supports enzymes that protect cells from oxidative damage.

Why Is NAD Testing Important?

  • NAD levels decline with age, chronic stress, poor diet, and lack of sleep
  • Testing enables targeted supplementation using NMN, NR, or other NAD-boosting supplements
  • Tracking NAD helps assess energy metabolism, resilience, and repair capacity

NAD testing offers insights for supplement brands, clinics, and wellness providers seeking personalized, measurable health optimization.
