The intermediate metabolite between the amino acid L-tryptophan and serotonin, is extracted from the bean of an African plant (griffonia simplicifolia). Symptoms associated with low levels of 5HTP include depression, anger, low self esteem, panic or anxiety attacks, irritability, extreme PMS. When your brain has adequate levels of 5HTP (serotonin) your brain cheerfully fires along with positive thoughts and feelings. For some it helps the body to relax and get a better nights sleep and for others it can help boost mood and stop carbohydrate cravings. 5HTP is an important mood improving food for your brain.
