NOW Supplements 5-HTP 50mg 90 Vegetable Capsules
5-HTP, the intermediate metabolite between the amino acid L-tryptophan and serotonin, is extracted from the seed of an African plant (Griffonia simplicifolia). 5-HTP readily crosses the blood-brain barrier and increases central nervous system (CNS) synthesis of serotonin. Serotonin can affect sleep, and many other important biological functions.
Adult Dosage: Take 2-4 capsules daily, 30-45 minutes before bedtime with food.
