Iodine is a trace mineral that is required for proper thyroid function; iodine is a component of thyroid hormones, and crucial for brain and nervous system development. The primary source of iodine in the American diet is iodized salt, and diets that exclude or minimize salt are likely to be low in iodine. On the other hand, regular consumption of seaweed or sea vegetables (such as kelp), may provide an excessive amount of iodine; too much iodine can also negatively affect thyroid function. Dr. Fuhrman recommends avoiding salt and supplementing with iodine to achieve adequacy (iodine is included in Dr. Fuhrman’s line of multivitamin and mineral supplements).
To assure that your iodine is favorable, neither too low or too high, you can test your iodine levels at home. ZRT Laboratory’s Iodine Test measures iodine from two dried urine samples to evaluate iodine status. Collecting and shipping the samples is simple and convenient—the two urine samples are dried on filter paper, and the filter paper is shipped to the laboratory.
