![]() ![]() In fact, certain supplements marketed toward those looking to promote thyroid health may be dangerous to take.įor example, many thyroid supplements contain high amounts of iodine and may contain thyroid hormones. Still, for people who don’t have thyroid issues and follow a well-balanced, nutrient-dense diet, there’s typically no need to take thyroid-specific supplements. There’s no doubt that a nutritious diet that provides optimal nutrient levels is important for maintaining thyroid health, nor that nutrient deficiencies can lead to thyroid issues. Should you take thyroid-specific supplements? ![]() These populations include people on restrictive diets, people who are pregnant or breastfeeding, and those who have a thyroid condition or other health issues. ![]() However, certain populations may need to supplement their diet with vitamins, minerals, and other nutrients to maintain overall health, including the health of the thyroid. Being deficient in one or more nutrients can negatively affect thyroid health and increase your risk of thyroid disease ( 7, 8, 9, 10).įor most people, following a nutrient-dense diet rich in whole foods is enough to maintain optimal thyroid function. Other nutrients, including B vitamins and vitamins A and E, are also needed for optimal thyroid function. Iron deficiency is associated with thyroid dysfunction ( 6). The thyroid needs iron to convert T4 into T3, the active form of thyroid hormone. An optimal concentration of zinc is needed for healthy levels of T3, T4, and thyroid-stimulating hormone (TSH) ( 5). The mineral zinc is required for thyroid hormone production. Iodine deficiency causes thyroid disease ( 3, 4). Triiodothyronine (T3) and thyroxine (T4) are thyroid hormones that contain iodine. In fact, currently, the only known role of iodine is to support thyroid hormone production. The thyroid contains high amounts of selenium, and a deficiency can lead to thyroid dysfunction ( 2). Selenium, a mineral needed for thyroid hormone production, helps protect the thyroid from damage caused by oxidative stress. Here are some of the most important nutrients for thyroid health: If you walk down the supplement aisle of your favorite health food store, you’ll likely see a section dedicated to thyroid health.ĭue to the prevalence of thyroid conditions, many supplement companies have started making supplements that are designed to “support thyroid health.”Īlthough some of these products are harmless, certain thyroid supplements may lead to negative side effects and can even harm your thyroid.īefore addressing why thyroid-specific supplements may not be the best choice for everyone, it’s important to explain what nutrients the thyroid needs for optimal functioning. ![]()
