Understanding NAD+: The Science of Cellular Energy
Nicotinamide adenine dinucleotide (NAD+) is an essential coenzyme present in every living cell, playing crucial roles in energy metabolism, DNA repair, and cellular aging processes¹. As we age, NAD+ levels naturally decline by approximately 50% by age 50, contributing to decreased cellular function and age-related health challenges.
The Biochemistry of NAD+
Cellular Functions
NAD+ serves multiple critical functions in human physiology²:
Energy Production: Essential cofactor in oxidative phosphorylation and ATP synthesis
DNA Repair: Activates PARP enzymes responsible for DNA damage repair
Circadian Rhythm Regulation: Influences metabolic cycles and sleep-wake patterns
Sirtuins Activation: Supports longevity pathways and stress resistance
Calcium Signaling: Regulates intracellular calcium levels and secondary messaging
Age-Related Decline
Research published in Cell Metabolism demonstrates that NAD+ levels decrease systematically with aging due to³:
