Results from testing 47 brands of prenatal vitamins were shocking.
The study was conducted at the University of Colorado Anschutz Medical Campus, where researchers purchased prenatals both online and in local stores. They also included some prescription prenatal vitamins.
Vitamins were tested for levels of 2 essential pregnancy nutrients (choline and iodine) as well as for toxic heavy metal contaminants.
They found:
✖️Only 12 of the products (26%) listed choline content, and of these, only 5 contained the correct amount as labeled.
✖️While about half of the products listed iodine on the label, only 4 contained the correct amount as labeled.
✖️7 products exceeded the safety limit of arsenic, 2 for lead, and 13 for cadmium.
Choline is extremely important for nervous system development, and iodine is needed for healthy thyroid function.
Dietary supplements are not regulated by the FDA, which means it is up to consumers to identify brands that maintain the highest standards of efficacy and purity.
