Detection of impurities in dietary supplements containing l-tryptophan

Sachise Karakawa et al.

Summary: Impurities in nine dietary supplements containing l-tryptophan were evaluated using HPLC methodology. Higher levels of total impurities were found in five tested products compared to the thresholds mentioned in food chemical codex or pharmaceutical-grade l-tryptophan standards implemented in the EU. The presence of 1,1'-ethylidenebis-l-tryptophan (EBT) was specifically tested using liquid chromatography-mass spectrometry, but no detectable amounts of EBT were found. The high levels of unidentified impurities in some dietary supplements suggest potential health risks.
