Iodine:  Shielding Your Body from Hormone Disruptors

Iodine: Shielding Your Body from Hormone Disruptors

In the modern world, the human body is exposed to a variety of chemical substances that can interfere with the normal function of hormones. This is especially true for women due to the abundance of daily beauty products that use problematic chemicals. These substances, known as hormone disruptors, include Heavy metals and common chemicals such as parabens, phthalates, bisphenol A (BPA), and fluoride. And these hormone disruptors are more easily absorbed by the body when facing nutritional deficiencies. One primary nutritional deficiency that causes this is Iodine. In the United States, 96% of our population faces iodine deficiency, which causes a predisposition to low thyroid hormone production and damages the body's ability to detox from these hormone disruptors.

Understanding Hormone Disruptors

Hormone disruptors, or endocrine-disrupting chemicals (EDCs), are substances that can interfere with the endocrine system, the collection of glands that produce hormones. These disruptors can mimic, block, or otherwise interfere with hormones, leading to a variety of potential health issues. The most commonly discussed disruptors include:

Parabens: Used as preservatives in cosmetics and pharmaceuticals, they can mimic estrogen and potentially lead to reproductive issues.

Phthalates: Found in plastics and cosmetics, these chemicals are linked to reproductive problems and hormone changes.

BPA: Used in plastics and resins, BPA can mimic estrogen and has been associated with various health problems, including reproductive disorders and cancer.

Fluoride: Although primarily used to prevent dental decay, excessive fluoride exposure has been linked to various health issues, including thyroid dysfunction.

Heavy metals: Heavy metals like lead, mercury, and cadmium can disrupt hormonal balance by mimicking or blocking hormones, interfering with their production, transport, and metabolism. 

Iodine's Role in Detoxification

Detoxification is a vital bodily process by which toxins and other harmful substances are eliminated from the body, safeguarding overall health and preventing disease. Iodine (a key trace element) plays a significant role in enhancing the body's detoxification pathways. Here’s how iodine contributes to these critical processes:

  1. Support for the Thyroid Gland - The thyroid gland, which relies heavily on iodine, plays a pivotal role in detoxification. Thyroid hormones, produced with iodine, help regulate the body's metabolic rate, which includes speeding up the detox processes. A healthy thyroid ensures efficient removal of toxins through various elimination pathways, including the liver, kidneys, and skin.

  1. Removal of Heavy Metals - Iodine is known for its ability to help in chelating heavy metals like lead, mercury, and arsenic from the body. It binds to these harmful substances, making them more soluble and easier to excrete. This process is crucial for preventing the accumulation of metals that can lead to significant health issues, including neurological disorders and kidney damage.

  1. Antimicrobial Properties - Iodine possesses strong antimicrobial properties, which are beneficial in eliminating pathogens from the body. This can reduce the burden on the immune system and enhance overall health.

  1. Promotion of Apoptosis - Iodine plays a role in apoptosis, the programmed death of cells. This natural process helps to eliminate damaged or diseased cells, preventing them from turning cancerous. Iodine's influence on apoptosis helps maintain cellular health and prevents the accumulation of potentially harmful cells.

  1. Enhancing Liver Function - The liver is the body's primary detoxification organ, and iodine supports its function by regulating enzyme activity and ensuring the efficient breakdown of toxins. Proper liver function is essential for the detoxification of blood, management of chemicals, and production of critical proteins.

  1. Supporting Kidney Health - The kidneys are another key detoxification organ that benefits from iodine. By regulating thyroid function, iodine helps maintain a healthy metabolic rate, which in turn supports the kidneys in filtering blood, removing waste, and managing body fluids.

Iodine and Thyroid Hormone Production

Thyroid hormones are critical for cell differentiation, growth, and metabolic regulation. Iodine deficiency can lead to hypothyroidism (low thyroid hormone levels), which can cause various health issues, including weight gain, lethargy, and mental slowing. Conversely, adequate iodine intake ensures the proper production of thyroid hormones, supporting overall hormonal balance and health.

Recognizing the Symptoms of Iodine Deficiency

Iodine plays a crucial role in the proper functioning of the thyroid gland, which regulates hormones critical to our metabolism and overall health. An iodine deficiency can lead to a variety of symptoms and health issues that may initially be subtle but can become significantly debilitating over time. Understanding these symptoms is key to addressing the deficiency early and maintaining hormonal balance and overall health.

  1. Fatigue and Weakness

  1. Unexpected Weight Gain

  1. Hair loss

  1. Dry, Flaky Skin

  1. Feeling Colder than Usual

  1. Changes in Heart Rate

  1. Swelling in the Neck

  1. Learning or Memory Problems

Recognizing these symptoms can be a crucial step toward seeking appropriate nutritional guidance. Supplementing your diet with the right amount of iodine—found in foods like seaweed, fish, dairy, and iodized salt—can help maintain a healthy thyroid and protect against the disruptions caused by hormonal imbalances.

Performing an Iodine Patch Test

An iodine patch test is a simple, at-home method used to gauge the body's iodine levels. To conduct the test, you'll need a 2% tincture of iodine, which can be purchased at most pharmacies. Follow these steps:

  1. Clean the Area: Select a small patch of skin, typically on the inner part of your forearm. Clean the area with soap and water to remove oils and dirt, ensuring the iodine adheres properly
  2. Apply Iodine: Using a cotton swab, apply a small square (about the size of a dime) of iodine to the cleaned area. Let it dry completely without touching it.
  3. Observe the Patch: Over the next 24 hours, observe the coloration of the iodine patch. If the iodine patch disappears or significantly fades in less than 24 hours, it might suggest an iodine deficiency. This occurs because the body may absorb the iodine more quickly if it is lacking.
  4. Record Results: Note how quickly the stain fades or disappears. This is not a definitive test, but it can be a helpful preliminary indicator of iodine need.
  5. Consult Healthcare Provider: If the test suggests a deficiency, it is advisable to consult with a healthcare provider for further evaluation and to discuss the need for possible iodine supplementation.

Benefits of Iodine Supplementation

Iodine supplementation is crucial for optimal health, detox, and for those at risk of deficiency. It supports thyroid function by aiding hormone production that regulates metabolism, energy, and body temperature. Here are key benefits of including iodine in your daily regimen:

(Iodine supplementation is NOT recommended for those with hyperthyroidism due to its ability to activate thyroid hormone production).

  1. Enhanced Thyroid Function: Iodine is crucial for the synthesis of thyroid hormones. 
  2. Improved Cognitive Function: Adequate iodine levels are essential for brain health and cognitive function. 
  3. Detoxification Support: Iodine plays a role in the body’s detoxification processes, helping to eliminate toxins and potentially harmful substances, such as heavy metals.
  4. Boosted Immune System: Iodine has antimicrobial properties that can enhance the immune system's ability to fight off infections and maintain overall health.
  5. Increased Energy Levels: By ensuring the thyroid gland functions efficiently, iodine supplementation can help sustain higher energy levels.


Regular iodine supplementation is an effective way to prevent iodine deficiency and support overall wellness, maintaining a balanced and healthy lifestyle. Iodine is essential for thyroid health and hormonal balance, and its role in protecting against hormone disruptors shows great promise. While ensuring adequate iodine intake is crucial for general health and may help shield against environmental hormone disruptors, it's important to remember that if you’re dealing with hyperthyroidism, iodine supplementation is NOT recommended due to its ability to activate thyroid hormone production. As always, consult your healthcare provider before supplementing for your individual health needs.
