What is 5-hydroxytryptophan (5-HTP)?
5-HTP is a derivative of the amino acid tryptophan. It is used to boost serotonin in the body. 5-HTP is also the precursor of melatonin, which regulates sleep cycles. Some findings show that 5-HTP may ease symptoms of depression, anxiety, and insomnia. Other studies show that 5-HTP may be useful in controlling appetite and pain. There are also a few studies that show no benefit with supplementation of 5-HTP.
