Would You Like Some Gravy with Your Tryptophan?
Tryptophan is one of the 20 standard amino acids, but one of four aromatic amino acids. (FYI: The ring makes it aromatic.) Tryptophan is an essential amino acid, meaning humans cannot make it from other building blocks. Yes, that includes you, my magical friend. Tryptophan must be taken into the body from food (or supplements).
