Iodine is needed for the synthesis of thyroid hormones, which are required for normal growth and development, particularly of the brain and central nervous system. Iodine deficiency is still one of the most common micronutrient deficiencies in the world affecting up to 700 million people. Inadequate intake is the main cause of iodine deficiency as the natural iodine content of most foods is low. Iodine intakes can be improved through fortification with universal salt iodization as recommended by the World Health Organization. For segments of the population who do not consume fortified foods or those segments of the population with high dietary iodine requirements, such as pregnant and lactating women, additional iodine in the form of supplementation is suggested. Currently, some countries including the USA, Canada, Australia and New Zealand have recommended that pregnant and lactating women take a daily iodine supplement, despite a lack of randomized trials to support the efficacy and safety of routine iodine supplementation, particularly in populations with less severe iodine deficiency. The purpose of this special issue is to focus on the effect of increased iodine intake via iodine supplementation on iodine status and health outcomes in populations with moderate to mild iodine deficiency.
