Reasons Requirement and recommended dietary intakes

Approximately 1µg/kg body weight per day is necessary to prevent goiter. However a large safety margin is given and the RDA is about 100 µg/day. For pregnant and lactating women the requirements are higher, being 200-230 µg/day during pregnancy and 200-290 µg/day during lactation. The requirements increase if the diet contains goitrogens as they interfere with the biosynthesis of the thyroid hormones.
