What is Bromide? The toxic halide driving thyroid problems

By Lucy Rose Clinic

November 7, 2021

One of the most devastating chemicals to thyroid health is bromide. To be specific – bromate. For purposes of easy reading, I will use the term bromide as an overarching term for all forms of bromide.

Read on to learn about the silent invader inside your cells which is boycotting your thyroid.

What are Halides?

Halides, or Halogens, are a group of similarly structured elements found in the Group 7 classification of the Periodic Table. They are most commonly known as Bromine, Chlorine, Fluorine, and Iodine.

Unlike Iodine which is essential for life, bromide is an environmental toxin and an endocrine disruptor.

And I think you will be shocked to find out how much you are unknowingly exposed to daily.

This is especially important for breastfeeding mothers. Studies show decreased iodine and increased bromide transfer through mother’s milk to the suckling – not something you want your baby to be ingesting.

There are several forms of bromides that are used for a variety of manufacturing purposes. The reason it is used is due to bonding ability – it’s a sticky molecule.

Main routes of exposure

  • Methyl Bromide is an agricultural pesticide used on fruit.
  • Potassium Bromate is an additive in commercial baked goods and flours in the United States. Some countries, including the U.K. and Brazil, have banned its use in wheat flour and bread products
  • Sodium bromate is added to products such as hair dyes, and dyes found in textiles. Other forms of bromide can be found in commercial cosmetics
  • Bromidated Vegetable Oil (BVO) is added to many foods and beverages, especially to citrus-flavoured soft drinks to help enhance the flavour. Other forms of bromide can be found in colas
  • Bromide ions have been detected in some bottled drinking water and water filtration systems
  • Bromide is used as a chlorine alternative for pool and spa maintenance.
  • Both bromide and chlorine can be found in large amounts in car parts such as seats, armrests and door trims. PBDEs (bromide compounds) are used heavily as flame retardants, which would explain its use in automobile parts as well as in paints and household furniture.

Chlorine and fluoride come from sources like water used for bathing and drinking, toothpaste, cleaning products, and can also be found in the air we breathe. As we have unintentionally increased our levels of non-essential bromine, chlorine and fluoride to the body, our iodine status is pushed out so our iodine levels go down – resulting in thyroid issues, cysts, nodules, and abscess growths in the body, increased viral loads, and diminished brain function.

Interesting Scientific Findings

A case of a 22-year-old woman with bromide-induced hypothyroidism is presented. There have been no reports dealing with changes in thyroid function and thyroid morphologic characteristics associated with bromide intoxication. The characteristic histologic features of the affected thyroid gland included a marked hyperplasia of follicles lined by tall columnar follicular cells with foci of papillary proliferation and a loss of colloid materials in the follicular lumen. Ultrastructurally, thyroid follicular cells showed a marked dilatation of rough endoplasmic reticulum containing no electron-dense materials. X-ray microanalysis of the thyroid follicular cells revealed the presence of significant amounts of bromide and an absence of iodine. These indicated that severe hypothyroidism in this patient might be related to the accumulation of bromide in the thyroid follicular cells. – American Journal Of Clinical Pathology Jun 1, 1988

High bromide intake in the lactating rat dams dramatically decreased iodine and increased bromide transfer through mother’s milk to the suckling. The impact of seriously decreased iodine content and increased bromide concentration in mother’s milk on the young prosperity is detrimental. – Metabolism of Bromide and Its Interference with the Metabolism of Iodine.

The solution

The solution is simple. When you work with the Lucy Rose Clinic, you can access testing to guide your specific treatment strategy and the right dose of iodine for your needs with a script for high dose iodine and the right form. Bromide is displaced with the form of iodine classified as potassium iodide. Other forms of iodine will not displace bromide.

We use a specialist compounding pharmacy to make our patients nutrient formulas, which combines not only the right dose of iodine but includes all the other co-factors required for absorption and thyroid hormone correction.

The iodine used in the compounding formulas is created by mixing potassium hydroxide with iodine, resulting in the most bioavailable form of iodine – potassium iodide. It is not made from seafood or kelp, so people with allergies to iodine or seafood can safely take it.

So how do you get onto this amazing corrective formula? You book your first call!
