Fluoride And Your Thyroid

Common sources of fluoride

Did you know that fluoride was used to treat hyperthyroidism up until the 1950’s, prior to the development of other thyroid-suppressing medications?

Fluoride is effective as a thyroid suppressor at doses of 0.9-4.2 mg per day for hyperthyroidism. Most adults in fluoridated communities are ingesting between 1.6 and 6.6 mg of fluoride per day from water inadvertently suppressing their thyroid function!!

Fluoridation partially began as a collaborative effort between dental associations, the U.S. government and sugar lobbyists who wanted to find a solution that would allow people to have fewer cavities while continuing to consume just as much sugar. Proper nutrition should be emphasized and should eliminate the need for fluoride.

Just like other halogens, fluoride may act as a trigger in inducing thyroid cell death and inflammation and leading to the development of thyroiditis and autoimmune thyroiditis.

Some people have reported improvement in thyroid symptoms and thyroid function tests following removing fluoride from their lifestyle.

Common sources of fluoride include
  • Supplements (check the labels)
  • Bottled beverages – due to fluoride content in water
  • Toothpaste- I use the Trader Joe’s Fluoride Free version
  • Black tea
  • Red tea
  • Canned food items
  • Black/red rock salt
  • Chewing tobacco
  • Medications
  • Tea

Your cup of tea could be sabotaging your thyroid!! Boiling water concentrates the fluoride instead of getting rid of it while freezing the water does not affect the concentration of fluoride. Fluoride is also found in tea, especially red and black tea. Tea leaves accumulate fluoride from the soil and pollution. The longer they stay on the tea tree, the heavier the fluoride content.

An article published in the journal Food and Chemical Toxicology said there is up to 4.5, 1.8 and 0.5 mg/L of fluoride in black, green and white teas, respectively, when brewed for five minutes. Chamomile and herbal tea contained 0.13 mg/L.

Fluoride-Containing Medications

Fluoride-containing medications include anesthetics, antacids, anti-anxiety medications, antibiotics, antidepressants, antifungals, antihistamines, cholesterol-lowering medications, anti-malarial medications, chemotherapy, appetite suppressants, arthritis medications, psychotropics, and steroids.

Some of the most commonly used medications that contain fluoride include:

  • Prozac®, Lexapro®, Celexa®, Paxil®: used for depression, anxiety, or OCD
  • Prevacid®: used for acid reflux
  • Diflucan®: an antifungal used for yeast infections.
  • Fluoroquinolone antibiotics (Cipro®, Levaquin®, Avelox®): used for UTIs and other infections
  • Celebrex®: used for pain
  • Lipitor®, Zetia®: used to lower cholesterol

Fluoride can be taken out by filters, but not just any filters. Fluoride is only removed by distilling the water, using reverse osmosis filtration systems, and activated alumina defluoridation filters. Most other filters do not remove fluoride. Exchanging black and red tea for white tea or herbal tea may be helpful as well.

I researched filtration systems for a while, but many of them were extremely expensive!  Some were in the thousands!!

I purchased an under the sink reverse osmosis filter on Amazon for $150. Looking at the directions, it would have been really difficult for me to install myself, so I had it installed by a professional handyman who specializes in filtration.

It took a few hours, but the total cost was a fraction what I would have paid otherwise! If you are in the Chicagoland area and looking for a handyman, let me know, and I will share his contact information.

I wish you all the best in your healing journey!
