L-Tryptophan is an essential amino acid, which means the body cannot produce it itself and it must be obtained through diet or supplements.
What is the difference between essential and non-essential amino acids?

How does L-tryptophan differ from other amino acid supplements?

L-tryptophan is best absorbed on an empty stomach, preferably 30 to 60 minutes before sleep or between meals.
