There are potentially serious risks to taking too much iodine, however, which is why I generally do not advise taking iodine supplements like Lugol's or Ioderol.
They may recommend you take it in the form of straight iodine (i.e., Lugol's solution), as a food like seaweed, as a food supplement like kelp, or as an herb, such as bladderwrack, that contains high levels of iodine.
