Serotonin levels in the body are associated with the regulation of sleep, mood, and appetite. 5-HTP is the direct precursor to serotonin and cannot be shunted into other metabolic pathways — making it more effective than L-tryptophan. Well absorbed and easily crosses the blood-brain barrier. Contains pyridoxal 5'-phosphate (active B6), the necessary cofactor for serotonin conversion. Each lot tested for Peak X contaminants and is Peak X free.*
