Improve energy levels： NADH not only acts as an important coenzyme in aerobic respiration, but [H] of NADH also carries a lot of energy. Studies have confirmed that extracellular use of NADH can promote the rise of intracellular ATP levels, indicating that NADH can penetrate cell membranes and increase intracellular energy levels. From a macro perspective, exogenous NADH supplementation can...
