NAD+ is a coenzyme that is essential for many metabolic processes in the body. When combining this powerful coenzyme with ingredients in Limitless, NAD+ may enhance the effects of the stimulants by facilitating the breakdown of glucose and the production of ATP, the primary energy source for the body’s cells. Additionally, NAD+ may help prevent oxidative damage induced by stimulants, which can lead to cellular aging and disease. Overall, the combination of NAD+ and stimulants may have a synergistic effect, enhancing both the metabolic and protective functions of the coenzyme.
