Selenium and Thyroid Health

Meaning

Selenium and Thyroid Health describes the essential, interdependent relationship between the trace element selenium and the optimal function of the thyroid gland. Selenium is a mandatory cofactor for several crucial selenoproteins, most notably the iodothyronine deiodinases and the glutathione peroxidases, which are critical for the metabolism of thyroid hormone and the gland’s internal antioxidant defense. Maintaining adequate selenium status is vital for preventing oxidative stress within the thyroid and ensuring the efficient peripheral activation of thyroid hormone.
