In a shocking revelation, researchers of a new study published in The American Journal of Clinical Nutrition found alarming levels of lead and arsenic in several prenatal vitamins, while many others missed vital nutrients such as choline and iodine, which has raised concerns about the safety of expecting mothers taking these supplements during pregnancy.
Around 47 prenatal vitamins including 32 over-the-counter and 15 prescription were tested by the researchers from the University of Colorado Anschutz Medical Campus for their choline and iodine levels as well as the levels of arsenic, lead and cadmium in them.
