5 HTP, or hydroxytryptophan, is a natural precursor (building block) of the brain hormone serotonin that is responsible for producing a feeling of calm and well-being. Since the 1970’s an increasing amount of scientific research connects depression and anxiety with reduced amounts of serotonin.
Today, 5-HTP is often described as one of the most helpful natural substances to increase serotonin levels in the brain.
