                                Phenylalanine is an essential amino acid, meaning the human body cannot produce it and must obtain it from the diet. It serves as a building block for proteins and is a precursor for important neurotransmitters, but its healthiness depends heavily on individual health, particularly the presence of a genetic disorder known as PKU.
