Phenylalanine is an essential amino acid. [1][2] Phenylalanine is a precursor of L-tyrosine and together they lead to the formation of adrenaline which is converted into a brain chemical which transmits nerve impulses and is used to manufacture noradrenaline which in turn promotes mental alertness, memory, elevates mood and suppresses the appetite.
