100% pure pharmaceutical grade

5-HTP molecule

5-hydroxytryptophan, or 5-HTP, is used as treatment for depression and mood disorders. Its role as an intermediary in the biosynthesis of serotonin indicates that this chemical is effective in treating these and other serotonin-related disorders. It is also used as a prophylactic against chronic daily headache. 5-HTP may also be useful in treatment for migraines, since studies have shown that migraines occur when serotonin levels are low.

In addition, current research shows promise in using 5-HTP for treating children with night terrors. After six months of use 83.9% of the children treated with 5-HTP were free from their persistent sleep terrors. 5-HTP is also used as a supplement by users of MDMA (commonly known as ecstasy) to help replenish depleted serotonin, in an attempt to alleviate to a degree the depression and overall mental unsettlement that sometimes occurs in the days following MDMA usage.
