The Science, Explained Simply
5-HTP (5-Hydroxytryptophan) is an intermediate compound in the body's natural conversion of the amino acid tryptophan into serotonin, and it has been widely discussed in nutrition research for that reason. Griffonia simplicifolia is of scientific interest because its seeds are the richest known natural source of 5-HTP — which is why researchers studying the compound almost always start with this plant.
Each capsule lists exactly what it contains and at what concentration — so you can weigh the research and make your own informed judgement.
