Iodine update

As the iodine experience grows, I’ve made several unique observations.

Up to several times per day, I see people who are responding in some positive way to iodine supplementation. (See previous Heart Scan Blog posts about iodine: Iodine deficiency is REAL and The healthiest people are the most iodine deficient.)

Among the phenomena I’ve observed:

1) A free T4 thyroid hormone at the low end of normal, or even in the below normal range, along with a highish TSH (usually >1.5 mIU/L) are the most frequent patterns that signal iodine deficiency. Occasionally, a low free T3 value will also increase, though this is the least frequent development.

2) At a dose of 500 to 1000 mcg iodine per day, it requires anywhere from 3 to 6 months to obtain normalization of thyroid measures.

3) Reversal of small goiters also occurs over about 6 months.

4) Iodine intolerance is uncommon. If it occurs, using a low starting dose, e.g., 100-200 mcg per day, usually works. The dose can be increased gradually over the ensuing months.

5) Perceptible benefits of iodine occur only occasionally. The most common perceptible effects are increased energy and increased warmth, especially of the hands and feet.

6) Some people who have taken thyroid hormones for years will develop reduced need for their medication with iodine supplementation. In other words, their physician was inadvertently treating iodine deficiency with thyroid hormone replacement. Anyone already on any thyroid preparation(s), e.g., Synthroid, levothyroxine, Armour thyroid, Naturethroid, etc., should watch for signs of hyperthyroidism when iodine is added. But having your own thyroid gland make its own thyroid hormones is better and healthier than relying on the prescription agents. Just be sure to monitor your thyroid measures.

7) Iodine toxicity can occur–Two people in my clinic population developed iodine toxicity by taking 6000 mcg iodine per day for 6 or more months. (Both patients did it on their own based on something they read). Iodine toxicity is evidenced by shutting down your thyroid, i.e., marked increase in TSH, e.g., 15 mIU/L.

Most of the people in my clinic obtain their iodine from kelp tablets. Some use potassium iodine (KI) drops. A handful have used the high-potency Iodoral (12.5 mg or 12,500 mcg iodine per tablet); this was also the form that generated the toxic effects in the two females.

All in all, iodine deficiency is actually far more common than I ever suspected. Not everybody is iodine deficient. But a substantial minority of the Midwest population I see certainly are.

    Your post contains opposite advice to that given in this blog post at healthyskeptic:

    William Trumbower recommended using Trilodine capsules after a few weeks of Iosol for people who are presently on thyroid medication. I am presently taking Synthroid and have been for many years now. I have tried to find the Trilodine but with no success. Is there another name or product that will do the same thing, or could you advise me as where I can purchase it?

    I came across an account of Dr. Flechas's views on iodine-induced hyperthyroidism (he's one of the docs most experienced with iodine supplementation). Apparently it does happen on occasion, but it's not necessarily a reason to discontinue iodine. The source for this is:

    What happens to thyroid hormone production in the presence of iodine supplementation?

    Iodine supplementations should be prescribed only when iodine testing indicates iodine deficiency. Iodine testing kits can be ordered from my office (828 684 3233) by individuals or by medical practitioners.

    Traditional medical literature indicates that patients who have thyroid nodules or thyroid goiter may have the potential to develop hyperthyroidism when supplementing with iodine. Hence, before commencing iodine supplementation, it would be advantageous for a person to have their primary care doctor order a thyroid ultrasound to rule out the possibility of pre-existing goiter or thyroid nodules.
    The primary care doctor should also order thyroid lab work (to be used as a baseline) before prescribing iodine therapy and this lab work should be repeated and followed at regular intervals during the patient's iodine therapy.

    For iodine therapy patients not also on thyroid hormone replacement therapy, adjustments to the iodine therapy should be made if signs of hyperthyroidism should occur.

    Should signs of hyperthyroidism occur in patients who are taking thyroid hormone replacement therapy as well as taking iodine supplementation, the physician should first recommend an adjustment in the thyroid hormone therapy rather than in the iodine supplementation.

    This adjustment in therapy is recommended because iodine is required not only by the thyroid but is required for the proper functioning of many other tissues.

    The presence of pre-existing thyroid nodules or goiter does not preclude the patient from iodine supplementation therapy. In fact, in the extensive research with iodine therapy done in my office, I have seen many case of pre-existing thyroid nodules and goiter shrink in the presence of iodine therapy.

    Hyperthyroid patients. Graves disease patients and other with autoimmune disease take iodine also but use lithium and copper among other minerals (he didn't say) to decrease the overproduction of thyroid hormones. Iodine isn't reduced because it's the neutralizer of the thyroid.  Patients in a thyroid storm with high heartbeats are given iodine to calm it down as normal medical practice.


    Goiters. In some patients with goiters the iodine will stimulate it to produce more thyroid hormone and the patient will suddenly look hyperthyroid with elevated T4 and losing weight. As the goiter shrinks this normalizes.

    Sorry for the multiple identical posts regarding Dr. Flechas. Google (Blogger) kept giving an error that made it seem the posts hadn't been published.

    I second the healthy skeptic post. In the presence of TPO auto antibodies (Hashimoto's), it could backfire as the autoimmune attack may worsen.

    I've read that autoimmune thyroid disease is more common in iodine sufficient areas, which correlates too.
