According to a study published in the journal Nature Metabolism by the University of Washington School of Medicine on January 7, 2019, β-Nicotinamide Mononucleotide(NMN)can directly enter cells with the help of transporters and sodium ions, and act quickly, thereby increasing anxiety for people Dopamine level improves the bad mood caused by anxiety, increases the blood supply to the brain, and eases the brain decline caused by anxiety. The reaction mechanism has been confirmed by researchers. Therefore, we need to continue to replenish NMN daily to increase the energy level of nerve cells, enhance excitability and endurance, restore the vitality of the brain and body, and play a role in regulating the physiological clock.
