Iodine Selenium

Iodine Selenium

Iodine is a critical trace element for the production of thyroid hormones, which regulate numerous essential bodily functions including metabolism, growth, and development. Adequate iodine intake is vital for optimal brain development, especially during pregnancy and childhood. While iodine deficiency can lead to an enlarged thyroid gland (goiter) and potentially hypothyroidism, excessive iodine intake can also negatively impact thyroid function. Since the body cannot produce iodine on its own, it must be regularly obtained through dietary sources like seafood, dairy products, and iodized salt.

Selenium is another trace element that is significant for thyroid health. It is found in high concentrations in the thyroid gland and is a component of enzymes that play a role in the metabolism of thyroid hormones. Selenium also acts as an antioxidant, protecting thyroid tissue from oxidative damage. Sufficient selenium intake helps the thyroid gland function properly and can contribute to reducing the risk of certain thyroid conditions. Foods such as Brazil nuts, seafood, whole grains, and poultry are good sources of selenium. A balanced intake of both elements is essential for overall thyroid health and, consequently, for the harmonious functioning of many of the body's systems.
