In reply: While Zhou and colleagues disagree with our viewpoint that Australian “women planning a pregnancy and pregnant and lactating women should be advised to take an iodine supplement”,1 we note that they suggest any such recommendation should await the results of their planned randomised controlled trial (RCT) examining the effects of maternal iodine supplementation on maternal health and neurodevelopmental outcome of the offspring. They neglect to mention that the National Health and Medical Research Council (NHMRC) issued a public statement in January this year, with supporting evidence attached, stating that: “The NHMRC recommends that all women who are pregnant, breastfeeding or considering pregnancy take an iodine supplement of 150 μg each day”.2 Similar recommendations, based upon available scientific evidence, have been issued by the World Health Organization, International Council for Control of Iodine Deficiency Disorders, American Thyroid Association and American Endocrine Society.
