The 5-HTP (5-hydroxytryptophan) for our organic 5-HTP Griffonia tablets is obtained from the seeds of the African black bean (Griffonia simplicifolia). In cooperation with our African supplier and a German pharmaceutical company, we were the first company worldwide to produce a Griffonia extract that meets the high requirements of the EC organic regulation. BIO 5-HTP Griffonia tablets contain 50 mg of 5-HTP from organic Griffonia extract in one tablet. 5-HTP is a precursor of serotonin. Serotonin is also called the “happiness hormone.” In addition to the naturally occurring vitamins and minerals, the organic Griffonia extract also contains the naturally occurring secondary plant substances in the plant. These herbal accompanying substances also support the usability of the natural ingredients.
