5-Hydroxytryptophan (5-HTP) is a compound found in the seed of the griffonia simplicifolia plant, which is the precursor to the neurotransmitter serotonin. EGCG (epigallocatechin gallate) is a compound found in green tea, or camellia sinensis, which helps 5-HTP to cross the blood-brain-barrier and reach the brain.



As the precursor to serotonin, 5-HTP directly increases serotonin concentrations in the brain. EGCG prevents peripheral serotonin conversion, which is known to have negative side effects, by inhibiting the enzyme aromatic L-amino acid decarboxylase.
