Why Halogens are Dangerous to the Thyroid

Your active thyroid hormone FREE T3 must be able to get into the thyroid hormone receptor sites that live on the outside of the cellular membrane. But there are toxins known as “halogens” which include chlorine, fluoride, and bromine that can cause challenges and block its entry.

In addition, although iodine is included on the halogen list, it is an essential mineral for healthy thyroid function and immunity. But the atomic weight of these halogens can displace iodine. For instance, fluoride easily displaces iodine in the body because it is much lighter and more reactive (atomic weight: iodine: 126.70 and fluoride: 18.99). Deficiency of iodine can cause hypothyroidism and other related thyroid issues resulting in weight gain, cold intolerance, hair loss, constipation, low libido and heart problems.

Although iodine is essential for healthy thyroid function and immunity, one must be very cautious about adding iodine without consulting their doctor or holistic health care practitioner. Hashimoto’s patients can be very sensitive to the introduction of iodine. Even though chances are they are iodine deficient, introducing iodine too soon could cause a very uncomfortable set of symptoms called a “thyroid storm”: rapid heart beat, increased body temperature, anxiety and body aches.

But don’t worry. There are many steps you can take to clean up your thyroid receptors and rid your body of halogens. Make sure you have a chlorine water filter for your shower (mercola.com has a really good one), stay away from fluoride toothpaste and read all labels including cereals, drinking water and processed foods and start taking very low doses of selenomethionine if your practitioner finds you are deficient in selenium.
