NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme studied for its critical role in cellular energy production, mitochondrial health, and age-related research. It is found in every cell of the body and is essential for numerous metabolic processes.

Research has shown that NAD+ levels decline with age, leading to decreased cellular function and energy production. Supplementation with NAD+ is being studied for its potential to restore these levels and support healthy aging.
