NAD+ — 100mg

Nicotinamide adenine dinucleotide (NAD+) is a critical coenzyme present in every living cell, essential for energy metabolism, DNA repair, and cellular signaling. Research has extensively documented the age-related decline of NAD+ levels and its association with mitochondrial dysfunction, genomic instability, and metabolic impairment. Studies have investigated exogenous NAD+ supplementation for its effects on sirtuin activation, circadian rhythm regulation, and neuroprotection. NAD+ remains one of the most actively studied molecules in longevity and cellular aging research.
