Iodine is important in pregnancy

Most women know that it is important to take folic acid before and during pregnancy.  A recent Western Australian study found that not as many women know the importance of ensuring adequate iodine levels in pregnancy.

Almost as important as ensuring adequate levels during pregnancy is ensuring enough is being taken before pregnancy.

It was discovered that only about a quarter of women supplemented with iodine prior to pregnancy whereas 66% used an iodine supplement while pregnant.  This number is similar to other Australian states.
