Iodoral, an iodine supplement, may cause acne-like lesions on the body, sinus headaches, an unpleasant metallic taste in the mouth, and increased salivation and sneezing. Feeling warm in cold environments is an expected side effect of iodine supplements and not cause for concern, according to Optimox, the maker of Iodoral. Optimox recommends that anyone experiencing unusual symptoms while taking Iodoral stop use of the supplement and contact a physician.
Iodoral is a concentrated iodine supplement containing elemental iodine and potassium iodide. The tablets are coated with pharmaceutical glaze to reduce the unpleasant taste of iodine, notes Optimox. Iodoral is available in two strengths: 12.5 milligrams per tablet and 50 milligrams per tablet as of 2015. The Optimox website recommends taking one to four tablets of Iodoral per day as recommended by a physician.
Rather than taking a supplement, individuals can also add more iodine to their diet; however, iodine does not occur naturally in most foods, explains Web MD. The most concentrated sources of iodine are found in the ocean, particularly in seaweed. Iodine is also added to some edible salts during processing. Individuals can increase their iodine intake by adding iodine salt, fish and seaweed to their diet.
The thyroid gland needs iodine to regulate the production of thyroid hormones. In extreme cases, iodine deficiency can lead to goiters, fibrocystic disease of the breast, breast cancer or infertility, reports WebMD.
