Selenium supplementation in the management of thyroid autoimmunity during pregnancy: results of the “SERENA study”, a randomized, double-blind, placebo-controlled trial

Randomized Controlled Trial

Human

This study found that taking selenium pills during pregnancy didn't make moms feel worse, didn't cause more problems for mom or baby, and was safe—even though it helped lower some harmful antibodies. So yes, it seems safe for pregnant women with thyroid issues.

Similar Assertions

Taking selenium supplements may lead to more side effects in adults with chronic autoimmune thyroiditis, without improving their health outcomes, so routine use is not recommended.

Taking selenium supplements does not change the levels of thyroid-stimulating hormone (TSH) in adults with chronic autoimmune thyroiditis, whether or not they are taking levothyroxine.
