The main role of vitamin B3 is to make NAD molecules. This is important because the NAD molecule sits at the crossroads of mitochondrial energy production (i.e., ATP), cellular repair and signaling, and cellular defenses. Unfortunately, NAD+ levels decrease with age. This is the bad news. The good news is that there are strategies that can be used to make more NAD+. One of these is vitamin B3.
Dopamine is one of the main neurotransmitters in the brain. It is most commonly recognized for its role in reward, motivation, and pleasure, but also plays a crucial part in modulating focus, motivation, cognitive flexibility, and emotional resilience. In addition to these creative-productive capacities and states, dopamine is one of the main regulators of motor control and coordination of body movements.
