Potassium Iodide – Applications of Lugol’s Iodine Solution

Potassium iodide is widely recognized in our society due to its association with the Chernobyl nuclear disaster. Following the explosion at the nuclear power plant, Lugol's solution was administered, especially to children and pregnant women, to prevent the absorption of radioactive iodine isotopes released from the fallout. This is just one of the numerous applications of potassium iodide.

Lugol’s solution was developed by Jean Lugol in the 19th century. The solution is obtained through a process called solubilization, which increases the solubility of a substance. Elemental iodine is minimally soluble in water, but with the presence of potassium iodide as a solubilizer, an iodide solution of appropriate concentration can be achieved.

To prepare Lugol’s solution, dissolve potassium iodide in a small amount of water, and then dissolve iodine in this concentrated potassium iodide solution. After complete dissolution, dilute the solution with water to make up 100 parts.
Store the obtained Lugol’s solution in containers with glass stoppers to protect it from sunlight. The solution can be used twice a day by adding 5-10 drops to milk with honey, for example.

Potassium iodide exists as white, hygroscopic crystals. It is commonly used as a component in iodine preparations, expectorants, antiatherosclerotic drugs, and medications for thyroid gland treatment.

Iodine – commonly known as tincture of iodine.
Iodine has long been utilized for disinfection purposes in medicine. It is a diluted solution of iodine in ethanol, typically with a concentration of approximately 90% by volume, and it contains potassium iodide as a solubilizer. Iodine is a dark brown liquid used to disinfect the skin, minor wounds, and even to treat water.

Iodine can be absorbed through the skin and mucous membranes, which is why seaside walks are often recommended. To determine if our bodies need iodine, a piece of skin can be moistened with iodine in the evening, which will turn yellow. In the morning, most of the iodine will have disappeared, indicating that the skin has absorbed it. This serves as a signal that the body requires iodine as it is often deficient.

Iodine is an extremely vital element that the body relies on. Insufficient levels of this essential element can lead to numerous health problems.
Hypothyroidism and thyroid hyperplasia: This condition is characterized by reduced secretion of thyroid hormones, which can be diagnosed through a specialist examination. Symptoms accompanying the disease include weakness, drowsiness, cold extremities, diminished mental and physical capacity, and muscle pain. Disturbed thyroid function may also cause rapid weight gain, infertility, fatigue, depression, recurring upper respiratory tract infections, deteriorating skin condition (dryness), weakness, and excessive hair loss. It’s worth noting that a significant number of patients with thyroid disorders develop cardiac issues. Iodine plays a crucial role in the treatment of the thyroid gland, as the highest concentrations of iodine in the body are found in thyroid hormones. A deficiency in iodine quickly disrupts the proper functioning of the thyroid gland.
Endocrine disorders: Iodine greatly impacts the endocrine system in women. It regulates estrogen levels, and an imbalance can lead to breast enlargement, lumpiness, soreness, and even cancer.
Nervous system disorders, including the brain: Iodine is crucial during fetal development, as a lack of this element can potentially harm the developing baby’s nervous system and result in mental retardation.
Hashimoto’s disease: This is an inflammatory disorder, specifically chronic thyroiditis, which can remain asymptomatic for years. The symptoms resemble those of hypothyroidism. A significant number of women are affected by this condition, possibly due to endocrine system disorders. However, the exact causes are still unclear and could include excessive and prolonged iodine consumption, the use of immunomodulatory drugs, stress, and genetic predisposition.
Irritability and reduced stress resistance: Symptoms such as impatience, anxiety, excessive nervousness, and more should not be disregarded, as they can contribute to the development of depression and a diminished sense of joy in life.

According to the World Health Organization (WHO), the maximum daily iodine dose is 600 µg, with 2000 µg (2 mg) considered toxic. However, I haven’t come across specific information regarding cases of overdose. In the aftermath of the Chernobyl nuclear power plant explosion, the administered doses were more than 30 times higher than the toxic level reported by the WHO. People were given 65 mg of iodine (equivalent to 10 drops of Lugol’s solution).

Currently, the daily dose of potassium iodide commonly used in the United States for an average individual is 150 mcg (0.15 mg). Pregnant women are advised to take 220 mcg, and during lactation, the recommended dose is 290 mcg. However, it is sometimes recommended to use higher doses, ranging from 300-400 mcg.

Dr. Abraham conducted studies on potassium iodide dosage, examining the body’s response to iodine intake. In one test, a loading dose of 50 mg of iodine was administered, and after

In conclusion, iodine plays a crucial role in our bodies, and its deficiency can lead to various health issues. The skin’s ability to absorb iodine indicates the body’s need for this essential element. Conditions such as hypothyroidism, endocrine disorders, nervous system disorders, and Hashimoto’s disease are closely linked to iodine deficiency.

Determining the appropriate dosage of iodine is important. While the World Health Organization sets the maximum daily dose at 600 µg, there is limited information available regarding overdose cases. In extreme situations like the Chernobyl disaster, higher doses were administered. The recommended daily doses of potassium iodide vary, with average individuals advised to take 150 mcg, pregnant women 220 mcg, and lactating women 290 mcg. However, higher doses up to 300-400 mcg may be recommended.

Studies by Dr. Abraham have shed light on the body’s response to iodine intake, with a loading test indicating that a healthy individual excretes 90% of a 50 mg dose within 24 hours. American scientists suggest a daily intake of 1-3 mg once adequate iodine saturation is achieved. On the other hand, Japanese scientists recommend much higher doses, up to 13 mg, which aligns with the traditional high iodine intake in their culture.

Ultimately, it is important to consult with a trusted specialist for individual interpretation and personalized guidance regarding iodine dosage. Ensuring an adequate intake of iodine through a balanced diet or supplements is crucial for maintaining overall health and preventing iodine-related deficiencies.
