USP statement on prenatal multivitamin study

December 23, 2024

Rockville, MD - A recent study published in The American Journal of Clinical Nutrition entitled "Content of Selected Nutrients and Potential Contaminants in Prenatal Multivitamins and Minerals: an Observational Study," reported the presence of heavy metals in higher levels than those set by USP for Elemental Contaminants in Dietary Supplements. USP has determined that the limits as well as the units were incorrectly applied and that the values presented in the first publication of the study were inaccurate.

USP has directly communicated with the author to clarify the correct limits and units.
