Unfortunately no, you can't "reverse" aging, it's a natural part of life but you can use the power of nutrition to help your body slow the process. NAD+ levels in the body are depleted with aging. Depletion of NAD+ levels is associated with a decrease of energy production in mitochondria, increasing oxidative stress, DNA damage, cognitive impairments and inflammatory diseases. NMN, the precursor of NAD+, has been studied to reverse these age-related complications and slow down the rate of aging by enhancing NAD+ levels in the body. One way that we might sustain healthy levels of NAD+ is by supplementing our bodies with nicotinamide mononucleotide (NMN).
