NAD+ (Nicotinamide Adenine Dinucleotide)NAD+ (Nicotinamide Adenine Dinucleotide)
Essential coenzyme for cellular energy production, DNA repair, and sirtuin activation. NAD+ levels decline ~50% between ages 40 to 60. Supplementation aims to restore cellular NAD+ for mitochondrial function, DNA repair, and anti-aging sirtuin activity.

How it works
Mechanism of action
NAD+ serves as electron carrier in mitochondrial oxidative phosphorylation (complexes I and II), substrate for sirtuins (SIRT1-7) which regulate metabolism and gene silencing, substrate for PARPs involved in DNA repair, and substrate for CD38-mediated calcium signaling.
