Did you know that Fluoride use to be used as a Thyroid suppressing drug for people with overactive thyroids? Yes, it’s true! Fluoride was found to be effective at suppressing or reducing thyroid function, according to research, and the dose needed to reduce thyroid function was low — 2 to 5 mg per day over a period of months. This is about the same amount of fluoride (or sometimes even higher levels) that is routinely put into the water supply throughout the U.S. It’s estimated that 70% of the water supply in the United States is fluoridated.
This was done to “solve the problem” of tooth decay. But this “solution” is just causing more problems. Fluoridation of water is not done in nearly all developed countries around the world except for the U.S.
One of the common side effects of an underactive thyroid is weight gain. Meanwhile the U.S. has absolutely obscene rates of obesity. Well, aside from the many shortcomings in the American diet, which I would say is the major culprit in our overweight problems, suppressing thyroid function certainly isn’t helping matters. Fluoride and your thyroid function are definitely linked.
What I recommend is filtering the fluoride out of your drinking water, and of course a healthy diet. Most common water filters do not effectively remove fluoride (such as Brita and Pur). The two types of filters that do reliably remove fluoride are reverse-osmosis filters and activated alumina filters. We have the reverse-osmosis filter in our house and it works great. We use it for drinking water (much better than buying bottled water) and for cooking.
You can still get fluoride to your teeth by using a fluoridated toothpaste. Just make sure you rinse your mouth well afterwards.
