If you use kelp you 1) don't get a lot of iodine and 2) may be getting heavy metals along with it. Check your source

Lugol's or Iodoral are sources of both Iodine and Potassium iodide, both forms of iodine that the body uses. You can make Lugol's yourself. Iodoral is the same proportions in tablet form.
