NOW 5-HTP 100mg 60 Caps

A little known, but no less effective natural remedy for fatigue, sleeplessness and feeling the blues. 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, mood, appetite, and many other important biological functions.

This is a mid-range dosage of 5-HTP.
