Iodine Interactions Overview

Check For Interactions With Iodine

Iodine

Also known as
  • KI
  • Lugol's Solution
Iodine Iodine is a mineral that is crucial for our body's ability to produce thyroid hormone, which helps control our growth, metabolism, and energy levels. A lack of iodine in the diet is a common problem around the world and can lead to intellectual development issues. Adding iodine to salt (i.e., iodized salt) has helped reduce this problem. Iodine is commonly utilized as a dietary supplement, both in multivitamin preparations and as a standalone ingredient as it is purported to have overall health and wellness benefits, not just in those who are deficient. One such standalone iodine product is 'Iodoral'. Studies have shown iodine supplementation may help improve cognitive function and boost energy levels but more research is needed. It is recommended that you should be under medical supervision if you plan on taking iodine as there may be a risk of certain side effects with high dosages.

Additional Details

Is Iodine Safe? Are They Any Warnings?

Iodine is a trace element necessary for the production of thyroid hormone. It is generally safe to use orally and topically in appropriate amounts. Oral iodine should not exceed the recommended daily intake level to avoid side effects like thyroid dysfunction and other complications. However, in some regions like Japan, higher dietary intake of iodine has been observed without adverse effects. It is also safe to use during pregnancy and lactation, but excessive intake may lead to increased iodine levels in breast milk and potential risks for the baby's development.

How Is Iodine Thought To Work?

Iodine is needed for the production of thyroid hormone, which plays a crucial role in regulating metabolism. It helps maintain the normal function of the thyroid gland and prevents iodine deficiency. The addition of iodine to salt has been effective in reducing deficiency in the US and Canada. Dietary sources of iodine include iodized salt, seaweed, marine products, eggs, and cow's milk.

Pharmacokinetics

Iodine exists in various forms and is commonly used as potassium or sodium salts. It can be taken orally as iodized salt or applied topically in the form of solutions or ointments containing povidone-iodine. The pharmacokinetics of iodine are not extensively studied.
