Iodine supplementation during preconception, pregnancy, and postpartum periods corrects maternal iodine insufficiency but shows no significant benefit for preventing preterm birth, low birthweight, or improving child neurodevelopment.

If you are pregnant or planning pregnancy, iodine supplementation is recommended to correct iodine deficiency, which is common. However, do not expect this supplementation to prevent preterm birth, low birth weight, or significantly boost your child's intelligence or motor development beyond what is achieved by correcting the deficiency. Stick to recommended prenatal doses.
