5-hydroxy tryptophan, or 5-HTP, is a precursor to the important neurotransmitter serotonin, which regulates several vital processes in the body, including sleep, emotional stability, pain sensitivity and cravings. Clinical studies show that 5-HTP helps to increase levels of serotonin in the brain.  


Take up to 3 capsules a day, unless directed otherwise by your physician. Take with water or fruit juice only (not with milk or other fluids containing proteins). For good sleep, take 30-60 minutes before bedtime.


Yeast, Griffonia simplicifolia extract 30%, cellulose, gelatin.
One capsule contains 49,5 mg 5-HTP.


Excess 5-HTP, especially when administered with vitamin B6, causes the liver to metabolize 5-HTP into serotonin, which may result in heart valve damage or disease (cardiac fibrosis). When combined with an MAOi or SSRI, 5-HTP can cause acute serotonin syndrome.
