What is NAD+ (Intracellular)?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of your body. It's central to energy metabolism, converting nutrients into cellular energy (ATP). Levels decline significantly with age.

Why NAD+ (Intracellular) Matters

High NAD+ levels are associated with youthful energy production, enhanced DNA repair, and sirtuin activation—key pathways in longevity and healthy aging. Restoring NAD+ is a major focus of anti-aging research.
