Natural Factors RegenerLife NMNSurge - Contains metabolically active nicotinamide mononucleotide (NMN), a unique anti-aging ingredient used to rejuvenate cellular health. This biologically active form of vitamin B3 is quickly converted by the body to nicotinamide adenine dinucleotide (NAD+), a metabolite needed for optimal energy production and cell renewal. By middle age, the body’s NAD+ levels have fallen to half their youthful levels. Declining NAD+ is a known factor in many metabolic and age-related health problems, contributing to underlying conditions, such as muscle and hearing loss, fatigue, and cognitive decline. As a direct precursor to NAD+, supplementing with NMN helps replenish age-related declines and support mitochondrial health.
