 L-phenylalanine is an essential (essential) amino acid used in metabolism as a precursor for the production of L-tyrosine and skin pigment melanin. In addition to the importance of producing endogenous tissues, L-phenylalanine is particularly important for the production of various messenger substances.

Although dopamine is also known as the happiness hormone, adrenaline and norepinephrine have effects on heart rate, blood pressure, concentration, alertness, and motivation.
