NMN (β-nicotinamide mononucleotide) is a direct precursor to NAD+, a critical coenzyme involved in energy metabolism, DNA repair, and mitochondrial function. NAD+ levels decline with age—by middle age, they may be half of early adulthood levels—leading to reduced energy and recovery. NMN enters cells and converts to NAD+, helping restore cellular efficiency. Research suggests potential in supporting cellular energy, cognitive function, healthy aging, and glucose/lipid metabolism, though human evidence remains limited. DUOZI NMN Capsules recommend 2 capsules daily with breakfast for three months. Suitable for middle-aged adults concerned about healthy aging and energy; not for pregnant/nursing women or those under 18.
