How much fluoride are you exposed to?
It would be quite a skill to avoid fluoride these days. Most water supplies have it, as do most toothpastes, nonstick pans, and many medications, such as Prozac (flouxetine). The average American gets somewhere between 1.6 and 6.6mg of fluoride each day.
The World Health Organization considers safe levels of fluoride in drinking water to be <1mg per liter. Studies in New Mexico have found that just 1.5mg/L of fluoride in water is linked to a reduction in the thyroid hormones T3, T4, and TSH.10
What most people don’t know is that fluoride was used through the 1950s to suppress thyroid function in cases of hyperthyroidism in South America and Europe.1
Thyroids at Risk from Halogens
The thyroid needs iodine to make a hormone called T3 (triiodothyronine). Iodine is in a class of minerals called halogens, along with bromine, chlorine, and fluorine, the element of which fluoride is the negative ion. When iodine is low in the body (the World Health Organization claims 40% of the world’s population live in areas at risk for iodine deficiency),3, 4 the other available halogens can uptake into and block the thyroid gland.
Fluoride has become ubiquitous in our food and environment. Low iodine levels combined with excess environmental fluorides may cause fluoride to uptake into the thyroid gland. From there, it may compete with iodine and act as an effective thyroid suppressant, just like it did in the 1950s.
Research from the ’50s shows what was needed to suppress the thyroid was just 2–5mg of fluoride per day for a couple of months.1 Many Americans are already exposed to these levels, putting our thyroids at risk.
In numerous studies, iodine supplementation has been found to significantly increase urinary detoxification of both fluoride and bromide,5 thus taking a significant toxic load off the thyroid. In one study, only one day after supplementing with 50mg of iodine, urinary excretion of bromide increased by nearly 50% and fluoride by 78%.6, 7
Are You Getting Enough Iodine To Protect Your Thyroid From Fluoride?
Research indicates the current RDA for iodine, 150mcg per day, may be too low. The new levels that I report in my article How to Protect Your Breasts indicate the need for 3–6mg per day to help inhibit toxic estrogens from absorbing into the breast.2 Some recent studies suggest just 1–3mgs per day of iodine may be sufficient.5

To help support optimal thyroid function, consider limiting fluoride exposure and adding iodine into your diet as a food or supplement.

8 Food Sources of Iodine8
- Cod, sardines, salmon, shrimp
- Yogurt, plain
- Salt (iodized), not exposed to air for more than 4 weeks
- Milk (cow’s)
- Fish sticks
- Eggs, boiled
Diets at risk for iodine deficiency include those void of ocean fish and sea vegetables, reduced salt diets (or consuming sea salt replacements instead), and vegetarian or vegan diets.
Vegetarians generally have significantly low levels of iodine, since our soils are iodine-depleted. In one study, iodine deficiency was noted in 25% of vegetarians and a whopping 80% of vegans.9
Dr. John’s Iodine Recommendation
- For thyroid and fluoride protection, I suggest 12.5mg of an iodine/iodide supplement (such as our Iodine HP) once every two weeks to flush unwanted halogens from the thyroid.
- For thyroid function and nutritional support, I suggest temporary supplementation with LifeSpa’s Thyroid Support (which contains seaweed-based iodine).

THE BERKEY WATER PURIFICATION SYSTEM HAS A FLUORIDE FILTER OPTION.
Dr. Alan Christianson has shown research that iodine can actually have a damaging effect on the thyroid. Frustrating that there’s so much contradictory information out there! My daughter was eating all the high iodine foods regularly (including seaweed snacks!) and was supplementing with iodine occasionally and she ended up hypothyroid and with multiple nodules. Her tests showed high iodine levels and her pediatrician was perplexed.
Yes, that is why I recommend getting iodine tested using a challenge test and suggest only 1 mg per day or better yet 12mg every two weeks.
Were you eating high iodine foods because you suspected a thyroid issue?
