Have any supplements been studied for hypothyroidism?

    If hypothyroidism is caused by insufficient iodine intake, an iodine supplement is indicated. Hypothyroidism has been found to occur concurrently with deficiencies in vitamin D, selenium, magnesium, iron, zinc, and vitamin B12, however, it is unclear if supplementation will improve symptoms of hypothyroidism. Black seed has also been studied for hypothyroidism [1], while Ashwagandha has been studied for subclinical hypothyroidism.[2][3]
