I’ve never experienced that feeling, and I took it three times a day, every day to help with sleep during my treatment. Even now I take 1 or 2 daily and still haven’t experienced any of that. So like most other supplements, it depends on the user’s own individual reaction to each supplement.
5-Hydroxytryptophan (5-HTP) is made naturally by the human body from the essential amino acid L-tryptophan; then the 5-HTP is converted into serotonin. So it’s not a synthetic drug or even an herb.
