5-Hydroxytryptophan (5HTP) is an amino acid involved in converting the amino acid L Tryptophan to Serotonin, a neurotransmitter or "messenger brain chemical" associated with the regulation of sleep. Melatonin is made from serotonin in the pineal gland in the brain and adequate amounts of melatonin allow us to sleep. Melatonin is also an antioxidant.

5HTP is very well absorbed by the body and taken into the bloodstream. It easily crosses the blood brain barrier and is readily available for serotonin synthesis in the central nervous system.

The synthesis of serotonin from 5 Hydroxytryptophan requires Pyridoxal 5 Phosphate (Vitamin B6), so this formula has the addition of Pyridoxal 5 Phosphate, the active form of B6.

5 HTP is derived from the West African Griffonia tree, the only natural source available.
