From 2020 this review offers a look into the natural sources of 5-HTP, the chemical analysis and synthesis, biosynthesis and microbial production. Evidence examining the physiological effects of 5-HTP in the treatment of depression, anxiety, panic, sleep disorders, obesity, myoclonus and serotonin syndrome are also discussed. 5-HTP toxicity and the occurrence of toxic impurities present in tryptophan and 5-HTP preparations are also discussed.
