Griffonia simplicifolia is the only plant in our Cognition formula not from India (it grows exclusively in Africa), and its seeds are the source of one of the most extraordinary nootropics that exists—the amino acid 5-Hydroxytryptophan, better known as 5-HTP, an important building block for the neurotransmitter serotonin. Most people familiar with 5-HTP use it to regulate the sleep cycle and appetite. But its biggest effect that we’ve seen is in supporting elevation of mood and well-being.
