Nicotinamide adenine dinucleotide (NAD ) is a vital coenzyme found in all living cells. It plays a key role in cellular energy production, metabolism, DNA repair, and overall cellular health. As individuals age, NAD levels naturally decline, leading to metabolic dysfunction, cognitive decline, and other age-related conditions. Research suggests that restoring NAD levels may support longevity, improve mitochondrial function, and enhance metabolic health.
