The fuel of cellular repair

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme in every cell. It powers DNA repair, energy production, and anti-aging sirtuins — but levels drop 50% by middle age.

Fact

Sirtuins: the longevity genes

Sirtuins (SIRT1-7) are enzymes that protect against aging by repairing DNA, silencing inflammatory genes, and boosting mitochondria. They require NAD+ as fuel to function.

Key Takeaway

NAD+ is the master fuel for cellular repair. Exercise, fasting, and precursor supplements (NMN/NR) may help maintain levels, but human longevity data is still emerging.
