Iodine is an element that is crucial for the health of the thyroid gland. It is essential for the production of two key hormones in the body, thyroxin and triiodothyronine. These hormones play a role in regulating a host of body processes. Some of these include promoting healthy resting metabolic rates, heart rate, heat production, and energy levels.*

Iodine is an essential trace element critical in thyroid hormone production. Eighty percent of all iodine is found in the thyroid gland in the neck. The thyroid hormones control the rate of metabolism throughout the body. The two iodine-dependent hormones of the thyroid, thyroxin (T4) and triiodothyronine (T3), have multiple roles in the body, including binding receptors that affect brain development, oxygen consumption, resting metabolic rate, heat production, and the release of fatty acids from adipose tissue. Low hormone levels result in a slowing of metabolism and a sluggish, lethargic feeling. High hormone levels result in hyperactivity and nervousness.

Iodine is required for proper growth and promotes healthy hair, nails, skin, and teeth. It also plays an important role in the immune system where it supports the microbicidal activity of polymorphonuclear leukocytes. Further, it is essential for the normal development of unborn children.

In adults, iodine deficiency is most commonly seen with goiter development (an enlarged thyroid gland). Iodine deficiency during pregnancy can lead to cretinism, a type of birth defect with serious mental retardation coupled with dwarfism.

Some foods such as raw cabbage, turnips, cauliflower, soybeans, and peanuts contain a substance called goitrogens, which inhibit thyroid activity. Prolonged consumption can lead to goiter development, but cooking deactivates these compounds. People who are on a strict salt-free diet are those who will benefit most from an iodine supplement.
