From fighting caffeine cravings to stomaching prenatal vitamins, moms-to-be take great care to make sure everything they put in their mouths helps to keep their growing babies healthy. Unfortunately, despite their efforts, most expectant mothers aren’t getting enough iodine, a mineral that impacts neurological development, according to new research.
The study, conducted by researchers from The University of Adelaide, followed nearly 200 Australian women throughout their pregnancy and six months after giving birth. Although eating bread fortified with iodized salt (a common practice in both the U.S. and Australia) increased levels of the nutrient, most women still had a mild deficiency, says lead study author Vicki Clifton, PhD, a professor of obstetrics and gynecology at The University of Adelaide’s Robinson Institute. Only women who also took a supplement throughout their pregnancy met the World Health Organization’s recommended intake of 220 micrograms of iodine.
Why is the nutrient so important? Iodine deficiency during pregnancy can lead to high blood pressure for mom and can also negatively impact baby’s physical and mental development. While eating iodine-rich foods (like seafood, yogurt, and fortified bread) can boost your intake, the easiest way to get the right amount is by taking an iodine supplement for expectant mothers, says Clifton.
That said, getting too much iodine is also dangerous; it can lead to hypothyroidism in both mom and the little one she’s expecting. So before popping any pills, ask your gyno for a urine test to see if you’re deficient. If your levels are good, there’s no need for a supplement—just keep your diet consistent throughout your pregnancy to ensure you continue getting enough of the nutrient.
