Essential amino acids cannot be produced by the body and must be obtained through diet or supplements. Non-essential amino acids can be made by the body from other nutrients. L-Tryptophan is an essential amino acid.
L-Tryptophan is one of the few essential amino acids and appears less often in supplement form than, for example, L-lysine or L-glutamine. Unlike some other amino acids, tryptophan must always be taken through diet or a supplement.
L-tryptophan is best absorbed on an empty stomach, preferably 30 to 60 minutes before sleep or between meals.
L-tryptophan in free form means that the amino acid is not bound to other substances such as proteins or peptides. This makes it directly available for absorption in the body.
