Iodine deficiency during pregnancy is serious for both the mother and the baby. It can lead to high blood pressure during pregnancy for the mother, and mental retardation for the baby.

Iodine plays an important role in development of the central nervous system. In extreme cases, iodine deficiency can lead to cretinism, a disorder that involves severely stunted physical and mental growth.

As iodised table salt contains iodine (because of government requirements), normally a supplement is not required. However as natural sea salt is becoming more and more popular then iodine levels are dropping. If you're pregnant or wishing to become pregnant please consult with your healthcare professional regarding your specific iodine requirements as it's likely you may require additional supplementation.
