How to take iodine<br>Choose an iodine supplement of 0.5 milligrams or less. If you think you aren't getting enough iodine and you don't want to visit the doctor, take a low dose of iodine. You shouldn't take more than 0.5 milligrams a day, as too much iodine can wreak havoc on your thyroid gland.
The person writing these instructions would agree that a 50 milligram iodine supplement would not be good for one's thyroid gland. 
He says taking any more than 0.5 milligrams would "wreak havoc" on the thyroid, and 50 milligrams is 100 times more than that.
