5-Hydroxytryptophan (5-HTP) is a form of amino acid that the body produces naturally and acts as an antecedent to the hormone melatonin and the neurotransmitter serotonin. The best 5-HTP supplements are derived from Griffonia Simplicifolia, an African plant. Moreover, it is a popular ingredient as it’s associated with boosting serotonin levels, providing many health benefits.

According to a study, 5-HTP may resist hunger-inducing hormones, which may aid in squashing appetite and result in losing weight. [1] Additionally, several clinical trials found that 5-HTP can be effective as an antidepressant. [2]

Another study shows that 5-HTP helped decrease the number of migraine attacks in 71% of the participants in the trial who took the substance for 6 months. [3] As previously mentioned, this amino acid also helps in creating melatonin, and as a result, it may also improve sleep quality, especially if combined with gamma-aminobutyric acid (GABA). [4]
