Iodine is not only a key element for maintaining thyroid function, but it also plays a vital role in many other systems and organs of the body, including the breast, ovaries, prostate, and brain. Iodine deficiency can have various adverse effects on the body, particularly on cognitive function and the immune system. In this article, we will explore the role of iodine and how to ensure adequate iodine intake to maintain health.

The effects of iodine are not limited to the thyroid gland.
Although most iodine is stored in the thyroid gland, it is also essential for the health of other organs. Iodine is widely found in the following locations:
- mammary gland
- uterus and ovaries
- prostate
- brain
- sperm
- Gastrointestinal system, etc.
Especially for infants, iodine deficiency at birth can negatively impact intelligence and may even lead to decreased learning ability. Therefore, ensuring adequate iodine intake is crucial for people of all ages.
Daily Iodine Requirements and Health Issues
The recommended daily intake ( RDA ) of iodine in the United States is approximately 150 micrograms, but in Japan, the average daily iodine intake is 1,000 to 3,000 micrograms, and Japanese people have a lower incidence of breast cancer and female reproductive problems compared to people in other regions. The scientific community has not reached a consensus on iodine requirements; although the upper limit is recommended at 1,100 micrograms, there is no clear evidence that exceeding this amount poses a health hazard.
Two different types of iodine
Iodine comes in two types: one for external use and one for internal use. External iodine is typically used to treat skin conditions such as fungal infections of the feet or warts, with povidone-iodine being a common example. However, for internal use, it is recommended to use iodine from food sources, such as seaweed like kelp. Seaweed is rich in iodine and other trace elements that contribute to health.
The effect of iodine on hormone balance
Iodine plays an important role in regulating estrogen levels, especially in cases of excess estrogen. Excess estrogen can lead to various health problems, including:
- Severe menstrual cramps
- Fibrocystic breast disease
- ovarian cysts
- Endometriosis
Iodine supplementation can help alleviate these symptoms. Swelling and pain in the breasts of women are often signs of iodine deficiency, and iodine supplementation can effectively reduce discomfort.
The role of iodine in men's health
Iodine is also crucial for men's health, especially for protecting prostate health. As men age, their testosterone levels decline while their estrogen levels rise relatively. At this time, adequate iodine supplementation can help prevent benign prostatic hyperplasia (BPH) and related problems.
The health benefits of iodine for the skin
Iodine can also help treat some skin problems, such as polycystic ovary syndrome ( PCOS ), cystic acne, and respiratory infections. Its antibacterial, antiviral, and antifungal properties make it very effective in treating foot fungus, warts, and skin tags.
How to effectively absorb iodine
The best sources of iodine are natural foods such as seaweed and shellfish. These foods provide not only iodine but also other trace elements, which help the body better absorb and utilize iodine. At the same time, avoid consuming too much raw cruciferous vegetables, brown rice, and soybeans, as certain compounds in these foods can interfere with iodine absorption.
Monitoring iodine levels
The most accurate way to measure iodine is through a 24- hour urine iodine test, which can rule out low iodine levels in the morning. Another simple method is to apply iodine drops to the skin and observe whether they are quickly absorbed. If the iodine disappears within a short time, it may indicate iodine deficiency.

Conclusion
Iodine is crucial for health, playing a vital role in maintaining hormonal balance, supporting the immune system, and promoting cognitive function. Ensuring adequate iodine intake and maintaining its balance is essential for improving overall health and reducing the risk of chronic diseases. If you frequently experience breast pain or irregular periods, iodine supplementation may be key to improvement.
