L-tryptophan is an essential amino acid: it is not produced endogenously and therefore must be included in our diet, where, on average, it represents just 1% of the amino acids we consume. L-tryptophan is the only precursor for the endogenous synthesis of serotonin, a chemical mediator that regulates mood.
