Description
L-5-hydroxytryptophan (L-5-HTP) is an endogenous amino acid precursor of 5-HT and melatonin that is commonly found in dietary supplements. L-5-HTP exhibits antidepressant and antioxidative activities. L-5-HTP acts as an antidepressant in clinical settings and shifts circadian rhythms in animal models. This compound also inhibits UV-induced apoptosis in monocytes.
