Why This Is Great for Thyroid Patients
Selenium plays a vital role in thyroid function — it's a key component of the deiodinase enzymes that convert inactive T4 into active T3, and of glutathione peroxidase that protects the thyroid from oxidative stress during hormone production. The thyroid gland contains more selenium per gram of tissue than any other organ in the body. Multiple clinical trials, including the widely cited studies in autoimmune thyroiditis, have shown that 200 mcg of selenomethionine can significantly reduce TPO antibody levels. For Hashimoto's patients, consistent selenium supplementation is one of the most evidence-supported interventions available.
