Is excess of iodine intake harmful?
Answer A safe daily intake of iodine has been estimated to be 1000 micrograms. When iodised salt is consumed the daily iodine intake will be in the range of 150 to 300 g of iodine. This quantity of iodine intake is 3 to 6 times less than the safe upper limit of iodine intake. About 90% of iodine consumed is eventually excreted in the urine.
