Understanding the Popularity & Efficacy of 5-HTP Supplements

Feelings of relaxation and other aspects of a balanced mood are highly dependant on a healthy release of neurotransmitters like serotonin. While many factors impact the synthesis and release of serotonin, few nutrients have been found to be as directly relevant to the process as 5-Hydroxytryptophan (5-HTP). This amino acid is known for its ability to cross the blood-brain barrier (something which ingested serotonin is incapable of), and to be freely converted to serotonin without biochemical feedback inhibition. However, exaggerated claims regarding 5-HTP’s potential to counter the effects of mental health conditions like depression should be viewed skeptically.1*
