NAD+ levels decline significantly during aging. NAD+ is required by the cell for the utilization of energy and other purposes.
Nicotinamide Riboside,NR, a Vitamin B3 analog, increases NAD+ levels in the body. Thus, taking NR may ameliorate some of the debilitating diseases of aging associated with the NAD+ depletion which occurs with aging.
NR is available online by various manufacturers.
High intensity interval training, by increasing human growth hormone production, might, along with the intake of NR significantly diminish the d frailty associated with aging and enhance functional capacity. Together, both might increase human life span.
This study might provide the basis for significantly increasing the quality and quantity of life for the human race through the use of NR along with high intensity interval training.
