Thyroid Red Flags

A few years ago, “Julie,” who was a patient of mine, complained that her thyroid blood test suddenly skyrocketed. She had been on thyroid medication successfully for years, and had always received regular thyroid testing. Her test revealed an unexplainable, sudden and extremely high rise in her thyroid stimulating hormone (TSH), indicating a crashing of thyroid function. Obviously, she was concerned!

I had been working with her for years to help stabilize her thyroid condition and was stumped as to what could cause such a sudden rise in TSH. I asked her if she would be OK with me “phoning a friend,” and she said “yes.” I called Ryan Drum, a PhD researcher and thyroid expert. On speakerphone with Julie in the room, I explained her situation to Ryan.

He quickly asked, “Has she bought a new car or new furniture recently?”

Julie and I looked at each other with jaws dropped! Just minutes prior, she had told me that she had just bought new furniture and couldn’t close the windows because the off-gassing was so extreme. She had also very recently bought a new car!

I responded, “Yes, she has recently done both.”

Ryan said, “The thyroid is the most sensitive gland in the body to environmental toxins. It is common for a thyroid to crash when exposed to a high dose of toxins – it is common when exposed to the off-gassing from a new car or new furniture.”

Possible Causes of a Thyroid Crash

There are a few possibilities that could be responsible for the thyroid’s negative reaction to off-gassing chemicals, heavy metals and a toxic environment. One being an iodine deficiency, which I have previously discussed in an article titled, “Iodine Deficiency.

Toxins in the environment may also block the conversion of the thyroid’s less active hormone, T4, into the more active form, T3. An inefficient conversion of T4 into T3 is perhaps the most common cause of a sluggish thyroid.

Toxins that Block T4 to T3 Conversion (1) and Suggestions to Improve Conversion

  • Heavy Metals (lead, mercury, cadmium, arsenic, nickel)

Suggestion: Seek Chelation Therapy and Colorado Cleanse.

  • Alcohol

Suggestion: Consider Colorado Cleanse for the liver.

  • Fluoride

Suggestion: Iodine supplementation to flush fluoride.

  • Radiation

Suggestion: Iodine supplementation.

  • Numerous medications

Suggestion: Consider Colorado Cleanse and iodine supplementation.

Heavy Metal Chelators

Removing heavy metals involves more than just the removal of the metals. The body has the ability to naturally detox heavy metals, but when digestive strength weakens so does the ability to detox hard-to-break-down chemicals like heavy metals. Step one is to boost digestive strength and cleanse regularly – something I write about extensively at

There are also natural substances that can help remove heavy metal load from the body and thyroid, and thus remove potential blockers of T4 to T3 conversion.

The most effective natural chelators are: (2)

  • Chlorella – chelates lead
  • Cilantro – chelates mercury
  • Garlic – chelates lead, cadmium and mercury
  • Alpha lipoic acid – chelates copper, cadmium, arsenic, mercury
  • EDTA – chelates lead, mercury, cadmium, aluminum
  • Shilajit – chelates cadmium and lead

Note: Be sure to supplement with minerals when chelating heavy metals, as any chelator will also pull minerals from the body.

Nutritional Deficiencies

Another factor that can contribute to poor conversion of T4 into T3 is a nutritional deficiency. These are the most common deficiencies that might be adding insult to injury: (1)

  • Iodine
  • Copper
  • Selenium
  • Chromium
  • Zinc
  • Iron
  • Vitamins A, B2, B6, B12
