Why you need iodine in pregnancy
If your fertility specialist told you to take your pregnancy with a large pinch of salt, you’d probably be quite taken aback. But that’s quite literally what you need to do.
Iodine, which is found in old-fashioned table salt, is essential for healthy brain development. Higher than usual intake of iodine in pregnancy is therefore crucial to ensure you baby gets what he or she needs while in the womb.
What iodine does for your baby’s growth and for you?
During your baby’s development, it’s important that he or she gets enough iodine to support brain and nervous system development, and to regulate his or her metabolism. While iodine is important in every person’s diet to avoid thyroid problems, pregnant women require even greater levels of iodine.
Studies have linked iodine deficiency during pregnancy with stunted growth and adverse neurodevelopment in babies and young children, while too much can harm the mother’s thyroid health. (Iodine intake in pregnancy—even a little excess is too much, Lee S Y and Pearce E N, Nat Rev Endocrinol, May 2015). It’s recommended, therefore, that women who are hoping to become pregnant or are pregnant get 220 micrograms (mcg) of iodine per day, and breastfeeding mums should get as much as 290mcg a day.
