Labdoor analyzed 3 of the best-selling Bacopa monnieri supplements in the United States. Tests were performed on bacoside content, pesticides, and heavy metal contamination (arsenic, cadmium, lead, mercury).
Bacosides are the bioactive component of the plant, Bacopa monnieri1. In our analysis, products ranged from having 26.4% more to 58% more bacosides compared to their label claims. On average, products deviated from their label claims by 38%.
Bacopa monnieri is known to leach heavy metals from the environment as it grows.2 However, all products recorded heavy metal concentrations below that of USP limits and recorded non-detectable levels of 20 common pesticides.
Analytical chemistry methods used to generate this report include high-performance liquid chromatography (Bacosides by British Pharmacopoeia), gas chromatography–mass spectrometry, and inductively coupled plasma-mass spectroscopy.
