5HTP is not a drug but a natural amino acid. it is the precurser to seratonin and helps level out your natural seratonin levels which affect mood and depression. if you are taking 5HTP you should not take anti-depressents or other MAO inhibitors simultaneously nor should you take st.jonhs wort at the same time. It has been shown to be even more effective than anti-depressants.
