The fact that Vitamin B6 plays an important role in your mood regulations is partly because this vitamin is necessary for creating neurotransmitters that regulate emotions, including serotonin, dopamine and GABA. It plays a role in your immune system function, brain development especially during pregnancy and infancy, creating haemoglobin, which is the part of red blood cells that carries oxygen.
