5-HTP

5-hydroxytryptophan (5-HTP) is an amino acid that is very similar to tryptophan, another common amino acid. Both compounds have been marketed for treating depression. However, batches of tryptophan contaminated with peak Xand other compounds have caused eosinophilia-myalgia syndrome. 5-HTP preparations may contain similar contaminants, so until further evidence is available, it may be best to avoid this compound.
