Double Potency Mood & Relaxation 5-HTP for Serotonin Production Plus L-Theanine, Rhodiola, Saffron and Holy Basil Dietary Supplement Double Potency 5-HTP Extra is a comprehensive formula designed to support mood and relaxation. Central to this formulation is 5-Hydroxytryptophan (5-HTP), a naturally occurring amino acid that is the immediate precursor of Serotonin. This plant derived compound sourced from the Griffonia simplicifolia, a climbing shrub native to West and Central Africa, helps the body to naturally produce this hormone, helping you attain an improved state of well-being. To complement the benefits of 5-HTP, this product also features L-Theanine that helps to increase alpha brain waves thereby supporting relaxation of the mind and body. This product also includes other botanicals such as Rhodiola and Damiana that have been used traditionally to support mood and are known for their adaptogenic properties.
