Iodine is an essential mineral that plays a vital role in numerous aspects of health, including thyroid function, detoxification, skin health, cancer prevention, and overall well-being. Yet, despite its importance, iodine deficiency has become alarmingly common. This is largely due to the depletion of iodine in our food and soil, combined with increased exposure to toxic halides added to almost everything sold commercially like bromide, fluoride, and chlorine, which compete with iodine in the body (Brownstein, 2013; Abraham, 2008).
Pioneering researchers and practitioners, such as Dr. David Brownstein and Dr. Guy Abraham, along with advocates like Melissa Galico, have dedicated decades to studying and promoting iodine supplementation as a solution to this growing deficiency crisis (Galico, 2011). Her book details her life as an FBI analyst and the medical struggles she was experiencing, when she started figuring out that one particular toxin had been added to the water and the role iodine has in helping with it. Their work highlights the significant impact iodine can have on restoring health and preventing disease.

Why Iodine is Essential For Everyone
While iodine is best known for its role in supporting thyroid function—helping the thyroid produce the vital hormones T3 (triiodothyronine) and T4 (thyroxine)—its benefits extend far beyond that. Iodine is critical for the health of multiple tissues throughout the body, including the breasts, ovaries, prostate, skin, and immune system (Zimmermann, 2009). A deficiency in this essential mineral has been linked to a range of health issues, from thyroid dysfunction and reproductive problems to infertility, skin disorders, and even an increased risk of cancer (Brownstein, 2013; Galico, 2011).
Key Functions of Iodine
Thyroid Health:
Iodine is crucial for producing thyroid hormones that regulate metabolism, energy levels, and growth. Without sufficient iodine, thyroid issues like hypothyroidism, goiter, and autoimmune disorders such as Hashimoto’s thyroiditis can arise (NIH, 2023).
- T3 and T4 Production: Iodine forms the backbone of T3 and T4 hormones. Without it, these critical hormones cannot be synthesized, leaving the body's metabolic processes—heart function, digestion, brain development, muscle control, and bone health—without proper regulation (Zimmermann, 2009).
Breast and Reproductive Health:
Iodine is essential for reproductive health, playing a role in conditions like fibrocystic breast disease, ovarian cysts, and potentially breast and prostate cancers (Brownstein, 2013). Adequate iodine helps balance estrogen and prevents abnormal cell growth in reproductive tissues (Mocchegiani, Garagnani, & Giovannini, 2013).
Skin Health:
According to Melissa Galico, iodine deficiency may contribute to skin issues like acne, eczema, and rosacea (Galico, 2011). Iodine regulates sebum production and has antimicrobial properties that help clear clogged pores and fight skin infections (Galico, 2011).
- Topical Use: Celebrities often use iodine-based creams for acne and blemish treatment. Its antiseptic and anti-inflammatory properties help reduce redness and clear breakouts faster (Galico, 2011).
Detoxification from Halides:
Toxic halides, such as bromide, fluoride, and chlorine, compete with iodine for absorption in the body. Found in many processed foods and pesticides, these substances disrupt thyroid function. Iodine supplementation helps displace these halides, restoring thyroid health and hormonal balance (Brownstein, 2013).
Heavy Metal Detoxification:
Iodine can assist in detoxifying heavy metals like mercury, lead, and cadmium (Brownstein, 2013). While not a direct chelator, iodine mobilizes these toxic elements, making them easier for the body to excrete. Clinical studies have shown increased heavy metal excretion in patients undergoing iodine therapy (Brownstein, 2013).
Cancer Prevention:
Emerging research highlights iodine’s role in preventing hormone-related cancers, especially breast and prostate cancer (Brownstein, 2013). Iodine promotes apoptosis, the body's process of eliminating abnormal cells before they turn cancerous (Mocchegiani et al., 2013). Both Dr. Guy Abraham and Dr. David Brownstein have reported significant improvements in cancer patients using iodine supplementation due to its impact on balancing estrogen levels (Abraham, 2008).
Antimicrobial Properties:
Iodine has potent antimicrobial effects, effective against bacteria, viruses, fungi, protozoa, and parasites (Abraham, 2008). Traditionally used as an antiseptic, iodine’s internal use also strengthens the immune system and defends against a broad range of pathogens.
Why the Type of Iodine Matters
Not all iodine supplements are the same. Research by Dr. Guy Abraham and Dr. David Brownstein reveals that the most effective iodine supplementation combines both iodine and iodide (Abraham, 2008). Lugol’s iodine solution, containing elemental iodine and potassium iodide, has been shown to saturate both the thyroid and other iodine-dependent tissues throughout the body (Brownstein, 2013).
- Elemental Iodine is more effectively absorbed by tissues like the breasts and ovaries.
- Iodide (potassium iodide), on the other hand, is primarily absorbed by the thyroid gland (Abraham, 2008).
This combination ensures that all iodine-dependent tissues receive the proper iodine needed for optimal function and detoxification.
Why Don't More Medical Professionals Use Iodine?
Well, it's all due to one experiment. The faulty experiment that led to widespread misconceptions about iodine’s toxicity was conducted by Dr. Wolff and Dr. Chaikoff in the 1940s. Their research involved radioactive iodine and incorrectly concluded that high levels of iodine suppressed thyroid function, a finding that has since been challenged by practitioners like Dr. David Brownstein. The study used radioactive iodine, a completely different compound from non-radioactive iodine, like Lugol’s solution, which had been safely used for decades (Brownstein, 2013; Galico, 2011). Before this misunderstanding, iodine was a staple in medical kits, carried by doctors and soldiers for treating infections and thyroid issues.
This misunderstanding has persisted, leaving iodine's many benefits overlooked in conventional medicine, even though practitioners like Dr. Brownstein and researchers like Dr. Abraham have shown its effectiveness in modern applications.
Dosage Recommendations for Iodine Supplementation
While the Recommended Daily Allowance (RDA) for iodine is set at just 150 mcg per day, many experts, including Dr. David Brownstein and Dr. Guy Abraham, suggest that higher doses are necessary to correct iodine deficiencies and achieve optimal health (Brownstein, 2013). Depending on the individual’s needs, the following dosages are typically used:
1. Minimal Dose (often insufficient):
- 12.5 mg per day, equivalent to one Iodoral tablet or 2 drops of 5% Lugol’s iodine solution (Brownstein, 2013).
2. Therapeutic Dose:
- For addressing conditions like thyroid dysfunction, fibrocystic breast disease, and for detoxification, doses of 25-50 mg per day are commonly recommended (Abraham, 2008; Brownstein, 2013).
This is why I typically start my clients on a therapeutic dose. I want them to experience noticeable results while also providing a maintenance level that helps protect against the constant bombardment of environmental toxins we face today.
3. High-Dose Therapy:
- In cases of severe iodine deficiency or toxic halide overload, doses of 100 mg or more per day may be used. This approach accelerates detoxification and ensures that tissues become fully saturated with iodine (Brownstein, 2013).
Companion Nutrients for Iodine Therapy
To support iodine absorption and prevent detox symptoms, companion nutrients are necessary:
- Selenium: 200-400 mcg/day to support thyroid function.
- Vitamin C: 2,000-5,000 mg/day to improve iodine absorption.
- Magnesium: 300-600 mg/day for detox support.
- Unrefined Salt: (Celtic or Himalayan) helps flush bromide and other halides from the body (Brownstein, 2013).
Addressing Concerns About Iodine Supplementation
Myth #1: Iodine Causes Thyroid Problems
Many believe iodine can trigger thyroid problems, but research shows iodine regulates thyroid function, especially when combined with selenium and other companion nutrients (Brownstein, 2013).
Myth #2: Too Much Iodine is Toxic
Iodine toxicity is rare and only occurs at extremely high doses (several grams daily). Dosages up to 100-200 mg/day have been safely used therapeutically under proper medical supervision (NIH, 2023).
Myth #3: Iodized Salt Is Enough
Iodized salt does not provide sufficient iodine, especially since most people consume less salt today. Moreover, iodine levels in salt are minimal and evaporate from salt over time (Leung, Pearce, & Braverman, 2011). Studies show that modern diets often fail to provide enough iodine.
Dispelling the Myth of Toxin Redistribution
A common concern surrounding iodine supplementation is whether it causes toxins, especially heavy metals, to be redistributed to other tissues during detoxification. Both Dr. Guy Abraham and Dr. David Brownstein have clarified that iodine doesn’t redistribute toxins—it mobilizes and facilitates their elimination from the body (Abraham, 2008; Brownstein, 2013). When combined with the right companion nutrients, iodine ensures the safe and efficient excretion of harmful substances like mercury and lead (Brownstein, 2013).
Conclusion: Why Iodine Supplementation is Essential for Everyone
Iodine supplementation offers a wide array of health benefits, from enhancing thyroid function and skin health to detoxifying heavy metals and environmental toxins, and even playing a role in cancer prevention. By choosing the right form, such as Lugol’s iodine or Iodoral, and following appropriate dosing with companion nutrients, individuals can safely improve their iodine levels and overall wellness.
