L-5-Hydroxytryptophan-d4

L-5-Hydroxytryptophan-d4 (L-5-HTP-d4; Oxitriptan-d4) is a deuterium labeled L-5-Hydroxytryptophan (HY-B1716) . L-5-Hydroxytryptophan (L-5-HTP), a naturally occurring amino acid and a dietary supplement for use as an antidepressant, appetite suppressant, and sleep aid, is the immediate precursor of the neurotransmitter serotonin and a reserpine antagonist[1]. L-5-Hydroxytryptophan (L-5-HTP) is used to treat fibromyalgia, myoclonus, migraine, and cerebellar ataxia[2][3][4][5][6].
