What are thyroid cofactors?

Two major cofactors which can significantly improve thyroid function if known to be deficient are iodine and selenium.

Iodine is the classic therapy for hypothyroidism as it is needed by the thyroid gland to synthesise thyroid hormones.

Selenium is another essential mineral needed for proper thyroid functioning. The thyroid gland contains more selenium than other body parts and during selenium deficiency, the body meets the selenium needs of the thyroid even before it sends selenium to the brain.
