Potassium Iodide

Potassium Iodide (KI) Can Shield You From Thyroid Cancer


With over 100 active commercial nuclear reactors in the United States, we live in constant threat of a nuclear emergency every day. A terrorist attack on any one of these facilities, or the release of a “dirty bomb” is also a possibility in today’s “highly charged” world. In fact, in an emergency, if you live within 200 miles of a nuclear reactor, you have a high risk of being exposed to significant doses of radioactive isotopes. In the event of a nuclear accident or attack radioactive materials can be released into the atmosphere, a high percentage of which is radioactive iodine. When a radioactive iodine cloud passes through a populated area, the radiation is concentrated into the thyroid gland of those exposed. The result is irreparable damage to the thyroid, which can lead to cancer. The 1986 Chernobyl accident in the Ukraine is a tragic example as is the Fukushima tragedy in Japan.

Even reactors in other countries can have adverse effects on people in the United States as prevailing winds can quickly spread the radioactive particulate matter from nuclear disasters.

The best protection against thyroid damage and thyroid cancer induced by radioactive iodine exposure is Potassium Iodide. This simple compound protects the thyroid by saturating all of the iodine binding sites in the gland, leaving no room for the binding of radioactive iodine. Potassium Iodide is a low-cost way to protect yourself and your family against the long-term consequences of exposure to radiation. When used correctly, potassium iodide tablets can prevent or reduce the amount of radioactive iodine taken up by the thyroid gland. Even the government and the military stocks up on potassium iodide in case of nuclear disaster.

The body can’t distinguish between radioactive and the benign version of iodine, which is necessary for thyroid function. Taking 130 mg of potassium iodide, the dosage widely recommended for the blocking of radioactive iodine in the event of a nuclear disaster, can quickly and completely protect the thyroid gland, which is one of the organs most commonly damaged by radioactive fallout.

It is important to remember that the precise dose of Potassium Iodide, whether it is 130mg or 125mg or 150mg (for a full-sized adult) is less critical than just simply offering the thyroid a good dose that will allow it to ignore the radioactive iodine that a person may have been exposed to.

Many Americans are cronically “undernourished” with iodine – iodine deficiency is common in North America. The FDA and CDC and other government agencies acknowledge this implicitly by recommending the use of Potassium Iodide in a radiation emergency since a thyroid gland that is not iodine deficient will not be prone to take up radioactive iodine.

Dr. Myatt’s Wellness Club offers a selection of supplements that contain potassium iodide.

Tablets are scored for easy breakage in the case of any need for exact or reduced dosages as recommended for children and pets.

How much do you need? The FDA recommends that you have one 130mg dose per person available for immediate use and up to 14 additional 130mg doses available for continuing use if needed.

Here is what the FDA recommends:

 What doses of potassium iodide (KI) should be taken for specific exposure levels?

Exposures greater than 5 cGy:
Birth through 1 mo.  – 16 mg.
1 mo. through 3 yrs.  – 32 mg.
3 yrs through 18 yrs.  – 65 mg. (Adolescents>150 pounds should take adult dose.)

Exposures greater than 10 cGy:
18 yrs through 40 yrs. – 130 mg

Exposures greater than 500 cGy:
Adults over 40 yrs – 130 mg.

7.  How long should potassium iodide (KI) be taken?

Since KI protects for approximately 24 hours, it should be dosed daily until the risk no longer exists.  Priority with regard to evacuation and sheltering should be given to pregnant females and neonates because of the potential for KI to suppress thyroid function in the fetus and neonate.  Unless other protective measures are not available, we do not recommend repeat dosing in pregnant females and neonates.

Remember that during an emergency, you may not be able to get to your home, thus it is recommended to have potassium iodide tablets stored in several places as well. Since the shelf life of this product is virtually unlimited, you should have to purchase your supply only once. Have this on hand for your family, and remember the children, pets, grandchildren, too!

Iodine for Radiation Protection

Iodoral – The Most Trusted Brand Of Natural Iodine

Iodoral (Iodine) For Healthy Thyroid FunctionIodoral® iodine tablets contain both iodine and iodide as the potassium salt. The preparation is absorbed into colloidal silica to prevent gastric irritation and specially coated with a thin film of pharmaceutical glaze to eliminate unpleasant taste.

Recommended Dose for daily use: 12.5 mg tablets – 1-2 tablets, 1-2 times per day as determined by iodine testing. A retest is suggested after 3 months. Best taken in the morning and afternoon to avoid nighttime stimulation.

Once whole body iodine sufficiency is achieved, Iodoral® maintenance dose is typically 1-4 tablets daily. People with thyroid disorders should work closely with their holistic physician or other health care professional.

NOTE: People with known iodine sensitivity should NOT use this product!

To make it easy to be prepared for a Radiation Emergency Dr. Myatt has Iodoral available:

Product # 309 Iodoral -90 tablets per bottle; 12.5mg iodine/iodide per tablet. $29.95

Modifilan (Laminaria japonica)

Thyroid and Immune Stimulant, Detoxification and Energizing Aid from the Sea

ModifilanThis “herb” (a variety of seaweed) might be the most important natural health discovery of the decade!

Modifilan was reportedly developed in Russia by scientists at the State Rehabilitation Institute, where victims of the Chernobyl nuclear catastrophe underwent treatment.

Hand-harvested from far Northern Pacific waters, Laminaria kelp has numerous health properties that set it apart from other species of seaweed.

Beneficial substances found in Modifilan include:

  • Organic iodine: Organic iodine feeds the thyroid gland, promoting normal metabolism and glandular function.
  • Fucoidan: a polysaccharide that promotes cancer cell death (apoptosis) and stimulates the immune system in animal studies. (1-4)
  • Laminarin: a polysaccharide that improves gut health in animal studies.(5)
  • Fucoxanthin: a natural pigment in the carotenoid family, is a potent antioxidant.(6-11)
  • Alginate: a natural polysaccharide that binds water and chelates radioactive toxins such as iodine-131 and strontium-90.(12-14)

Modifilan may be useful for:

  • Boosting the immune system with anti-viral and anti-cancer properties. (1-4, 15-21)
  • Helping lower blood sugar and cholesterol levels. (22-23)
  • Detoxifying the body from heavy metals, radioactive elements, free radicals and toxins.(12-14)
  • Aiding weight loss by improving thyroid, metabolism and GI-tract function.(24-25)
  • Helping smokers detoxify from heavy metals including strontium and cadmium.(12-14)

It takes 40 pounds or raw seaweed (conscientiously harvested to protect habitat) to make one pound of Modifilan.

Put some “pep in your step,” stimulate weight loss and energy while improving your immune system. This specially processed Laminaria is truly a unique gift from the sea.

Dr. Myatt’s Comment: Many of the “anti-cancer” and immune claims for Modifilan and other seaweed products have not yet been substantiated in humans. However, Modifilan is an excellent source of organic iodine and should be considered by anyone with low thyroid function.

Suggested dose:

For general health maintenance, 4-6 capsules per day.
For heavy metal chelation: 12 capsules per day.
For cancer: as directed by your physician (usually 6-12 capsules per day in divided doses).
