Getting Enough Iodine

Sea kelp

Iodine is essential for healthy functioning of the thyroid gland which, among other things, controls the body’s metabolism. During pregnancy and infancy, it also influences bone and brain development. Adults generally need 150 mcg of iodine per day. Pregnant and nursing women need more.

In the U.S., where iodized salt is commonly used in shakers and processed foods and iodine is used in commercial dairy production, most people get enough. I use sea salt and eat very little of the foods that are either naturally high in or supplemented commercially with iodine. Plus, I am hypothyroid.

So yesterday, I researched 2017 kelp reviews at:


  • Consumer Lab found three of the kelp supplements they tested contained more iodine than the FDA considers safe. Even worse, one contained arsenic.
  • Both sites approved Nature’s Life Icelandic Kelp, but the label itself says, “This product contains a chemical known to the State of California to cause cancer, birth defects or other reproductive harm.” I don’t know what’s going on with that.
  • My own price check at Amazon sometimes did and sometimes did not match what the reviews listed.

In the past, I have tested positive for thyroid antibodies (Hashimoto’s Thyroiditis).  At the moment, my thyroid antibody level is normal, but I am cautious about iodine, because too much could trigger a recurrence.

Since the one tablet per day dose of iodine for some recommended brands was considerably higher than I want to take, I chose Country Life Arctic Kelp from Amazon for $8.50. It contains 300 tablets (3 cents each) of 225 mcg of iodine and is eligible for Amazon’s FREE Shipping offer.

    You need to remember, all food is medicine. I don’t eat salt, but use iodine. When I get hungry for shell fish, then I use it. Same with craving dairy (which I can’t use, even the lactose-free, too much carbs 🙂 then I need a little (very little!) calcium supplement. Remember, too much calcium and the body reacts by flushing calcium from the body. My parents were dairymen, and raised by dairymen and the women all suffered dowager hump. Best calcium for me, make souse 🙂

      I’m reading The Magnesium Miracle. What she has to say about calcium is eye opening! Without enough magnesium (and most Americans are deficient), calcium makes the bones chalky. To make matters worse, fluoride binds up magnesium and makes bones brittle!


      • And the macabre part is, they knew all this when they forced America to used fluoridated water. It’s like Gov Moonbeam, D-CA, outlawing all guns on school campuses. He just turned schools into shooting galleries, knows it, but has to pay back supporters.
        Magnesium is an energizer. That’s why I like it. Most crop land is deficient in micro-nutrients, and that’s a major problem for 3rd world nations. Zinc deficiency is bad all over. Except, of course, the superfund sites Al Gore is determined we pay to clean up. Sites his family made millions on…

          We’ve been able to keep our area from fluoridating. I like to think my pithy letter to the editor last time they proposed it might have helped. I pointed out how the majority of our water is used for washing and flushing, not drinking, and that the majority of our parents are perfectly capable of affording fluoride drops or topical treatments for their kids if they want them. I proposed that, if they’re so concerned about the teeth of poor children, who are the least likely to drink water anyway, then they should put some money into offering it at the free vaccination clinics. It would be far cheaper than fluoridating ALL the water and would also spare those of us who don’t want fluoride from having to filter it out of our drinking water.
