NAD+ (Nicotinamide Adenine Dinucleotide) is a vital coenzyme found in all living cells, responsible for facilitating hundreds of metabolic processes — most importantly those related to cellular energy production, DNA repair, and anti-aging functions. As we age, NAD? levels naturally decline, contributing to fatigue, metabolic dysfunction, neurodegeneration, and reduced resilience to stress.

Restoring NAD levels through supplementation or therapy is now at the forefront of longevity and biohacking medicine, with research pointing to its role in extending healthspan, improving mitochondrial function, and activating sirtuins, the genes linked to aging regulation.
