Our 5-HTP comes from sustainably farmed, Organic Griffonia Simplicifolia plants in Ghana. Griffonia Simplicifolia is an evergreen shrub native to west and Central Africa. Its seeds can contain between 10-15% 5-HTP. The 5-HTP from the seeds is then pulled out using a water extraction process. This results in a pure, certified Organic, Non-GMO, and glyphosate-free 5-HTP.12
