Supplements for Thyroid Disorders

What the Research Shows

Clinical research on supplements for thyroid disorders shows mixed results, with few substances demonstrating strong efficacy. Selenium has moderate evidence for reducing thyroid antibodies in patients with Hashimoto's thyroiditis, though its impact on overall thyroid function remains debated. Iodine is critical for hormone production, but evidence is conflicting; while deficiency causes issues, excessive supplementation can worsen autoimmune thyroid disease in susceptible individuals. Other common supplements lack robust scientific backing. Evidence for the use of inositol to improve thyroid-related metabolic markers is currently insufficient. Similarly, there is weak or insufficient evidence to support the routine use of ashwagandha or magnesium for treating thyroid dysfunction. Many studies are limited by small sample sizes or poor design, meaning most current claims about these supplements are not supported by high-quality clinical trials.
