Both norepinephrine and dopamine are key neurotransmitters participating in the maintenance of mental alertness and acuity while promoting a Positive Mental Attitude. These two neurotransmitters are produced in the body from amino acid building blocks, primarily L-Tyrosine, and one of its precursors, DL-Phenylalanine. Viva Vitamins has combined these amino acids with L-glutamine and GABA to help with proper brain function and mental activity.
