Active Ingredient

Natural 5-HTP (5-Hydroxy-L-tryptophan): 50mg per capsule


5-HTP should not be used with antidepressant medication, including SSRIs and MAOIs.  If you are taking antidepressant medication please consult with your health care professional before buying. Not recommended for pregnant or lactating women.  High doses of 5-HTP may cause gastrointestinal upset in some people. May cause drowsiness.


Make sure that the 5-HTP you are using is from a natural source.

5-HTP can come in two different forms, a D form and an L form. The L form is the natural biologically active form. The cheaper synthetic 5-HTP is a 50/50 mixture of L and inactive D forms, so it is only half the strength of natural 5-HTP. And with synthetic chemicals there is also the additional concern of toxic impurities.
