Iodine: It’s an element we don’t think much about until something goes wrong. Yet, this trace mineral plays a pivotal role in ensuring our bodies run like well-oiled machines. Unfortunately, many people today are woefully deficient, leading to a myriad of health issues that can be easily avoided. In this post, we’ll delve into the benefits of iodine supplementation, symptoms of deficiency, and why relying on iodized table salt may not be cutting it.
Why is Iodine Important?
Our bodies don’t naturally produce iodine, making it an essential element that must be obtained through diet or supplementation. Found in every cell of our body, iodine is a fundamental element that assists with:
Thyroid health: Ensuring proper hormone production, which regulates metabolism.
Detoxification: Aiding in the removal of heavy metals and halogens like bromide, fluoride, and chlorine.
Immune support: Killing harmful bacteria, fungi, and pathogens.
Radiation protection: Helping to eliminate radiation from the body.
Hormonal balance: Supporting healthy reproductive and adrenal function.
Symptoms of Iodine Deficiency
Iodine deficiency is surprisingly common, and the symptoms are often mistaken for other health issues:
Fatigue
Weight gain or inability to lose weight
Brain fog
Cold hands and feet
Dry skin and brittle hair
Depression
Constipation
Swelling of the neck (goiter)
Hormonal imbalances
If you’re experiencing one or more of these symptoms, it may be worth considering whether iodine deficiency could be the culprit.
Why Iodized Table Salt Isn’t Enough
Relying on table salt for sufficient iodine intake might seem like an easy fix, but here’s the problem: Table salt has been stripped of most of its minerals and then “fortified” with iodine. However, the amount of iodine in table salt is often inconsistent, and the body doesn’t absorb it efficiently. Moreover, the health benefits of iodized salt pale in comparison to whole, unprocessed sea salts that retain their natural mineral content.

Different Ways to Supplement Iodine
There are several ways to incorporate iodine into your routine:
Oral supplements: The most common method, available as drops or tablets.
Transdermal application: Applying iodine topically allows for absorption through the skin.
Enema administration: Less common but sometimes recommended in alternative health protocols for detoxification.
Types of Iodine and Trusted Brands
When choosing an iodine supplement, there are a few types you’ll come across:
Lugol’s iodine: A popular, water-based iodine solution often recommended for those starting out. It contains 5% iodine and 10% potassium iodide.
Nascent iodine: A highly bioavailable form that many people find easier to absorb and tolerate. It’s considered gentler on the system.
Medical iodine: Used in higher concentrations, typically for clinical purposes like wound sterilization.
Some trusted brands include Global Healing Center, Optimox, and J. Crow's Lugol’s Solution. When using these supplements, starting with a low dose is key, such as 2-5 mg of Lugol’s iodine, and gradually increasing over time to avoid side effects like detox reactions (often referred to as the Herxheimer reaction).
The Health Benefits of Iodine Supplementation
Once you start supplementing with iodine, here are some of the benefits you may notice:
Improved energy levels and mental clarity
Weight management due to a more efficient thyroid function
Better skin, hair, and nails
Faster wound healing (when applied topically)
Boosted immune system to fight off infections
Hormonal balance, especially for women dealing with PMS or menopausal symptoms
Reduced sensitivity to cold temperatures
Iodine’s Detoxifying Powers
One of iodine’s standout benefits is its ability to help detoxify the body. It binds to halogens like bromide, fluoride, and chlorine and assists in their removal, which can be crucial in today’s toxin-heavy environment. Additionally, iodine is often used to protect against radiation exposure—making it a key supplement for anyone who has undergone radiation therapy or is frequently exposed to environmental toxins.
Iodine in History
Iodine has been a health powerhouse for centuries. During the 19th century, French physician Jean Lugol created his now-famous iodine solution to treat a range of medical conditions, from infections to thyroid disorders. Even today, some natural health practitioners gauge iodine deficiency by applying it topically to the skin—if the iodine absorbs quickly, it can indicate a deficiency, while slower absorption suggests your iodine levels may be sufficient.
Topical Applications and Other Uses
Iodine is incredibly versatile, both internally and externally. Applied topically, iodine can treat:
Acne and skin infections
Wounds and minor cuts
Fungal infections like athlete’s foot or ringworm
Internally, iodine can be used to:
Alleviate digestive issues
Support weight loss
Treat thyroid disorders like hypothyroidism
Starting Slow: A Protocol for Iodine Supplementation
To begin iodine supplementation safely:
Start with a low dose (2-5 mg of Lugol’s iodine or nascent iodine).
Gradually increase the dose over several weeks.
Monitor your body’s response for any signs of detox reactions (headaches, fatigue).
Avoid staining! Iodine can stain clothing and surfaces, so be cautious during application.
Iodine for Developing Babies and Brain Function
Iodine isn’t just important for adults—it plays a critical role in the development of babies, especially for brain function and cognitive development. During pregnancy and early childhood, iodine is crucial for the proper formation of the baby’s brain, nervous system, and overall growth. Studies show that iodine deficiency during pregnancy can lead to developmental delays, reduced IQ, and cognitive impairment in children.
In fact, iodine is so important for brain development that many health practitioners recommend applying iodine topically to a baby’s feet. This simple method feeds their rapidly growing brains, helping to support proper neurological development. The skin on the feet readily absorbs the iodine, allowing it to bypass the digestive system and get to work quickly. Plus, the gentle application on the feet is a safe way to introduce iodine to infants, promoting better cognitive outcomes and potentially leading to smarter, healthier kids.
In developing babies, iodine is essential for:
Brain development: Ensuring that neurons connect properly, promoting intelligence and memory.
Growth: Supporting healthy bone and tissue development.
Thyroid function: Regulating hormones that control growth, metabolism, and brain function.
Ensuring adequate iodine levels during pregnancy and early childhood can be one of the simplest yet most impactful steps in promoting long-term health and intelligence in children. So, whether you’re a soon-to-be parent or already raising a little one, adding iodine supplementation—through the mother’s diet or topically to your baby’s feet—can make a big difference in their cognitive and physical development.
Conclusion:
Iodine supplementation offers a myriad of health benefits, from supporting thyroid function to aiding detoxification and boosting immunity. Given the deficiency symptoms and modern dietary shortfalls, it’s an often-overlooked yet essential part of maintaining optimal health. By incorporating iodine—whether through oral supplements, topical application, or other methods—you may notice significant improvements in your well-being.
So, if you’ve been feeling sluggish, struggling with your weight, or just want to support your body’s natural detox pathways, it might be time to add a little iodine to your life.
