Natural thyroid supplements

Updated June 13, 2017

The thyroid, located in the throat, is an important gland for metabolic health. The thyroid gland secretes thyroxine, a hormone that controls the body's metabolism and utilisation of fat. The decline in the thyroid gland, or hypothyroidism, affects concentration and causes confusion, memory loss, cold hands and feet, weight gain, dry skin and low energy levels. An overactive thyroid, or hyperthyroidism, is also a dangerous condition. A number of natural supplements can help maintain a healthy thyroid.


Iodine is an important supplement for thyroid health, as it is required for thyroid hormone synthesis. A deficiency of iodine in the diet causes goitre, developmental disorders in children and thyroid disorders. Iodine is present in dietary additives, water sources, medications and dietary supplements and is used by the body to make thyroxine, a hormone essential for thyroid health. Iodine is converted to iodide in the body, where it is incorporated into hormones that are stored in the thyroid gland and released into the blood stream.


Selenium is another essential supplement for proper thyroid function, according to Progressive Health. Selenium is a trace mineral that the body needs in small amounts to function properly. Selenium is present in most seafoods. Selenium supplementation as part of a healthy diet also helps to relieve hypothyroidism and may be combined with iodine supplements to regulate the function of the thyroid hormone.

B-Complex vitamins

B vitamins are water-soluble and are dispersed throughout the body. Incorporating B-complex vitamins into your diet helps to increase oxygen levels in the body's cells, improve energy levels, build the adrenal glands and calm the nerves, according to Components of the vitamin B complex all support the thyroid in different ways. Vitamin B2 supplements support the metabolism of fats, proteins and carbohydrates. Vitamin B3 is found in small amounts in the body, so proper supplementation assists in the maintenance of healthy thyroid hormone production. Vitamin B6 plays an important role in metabolising unsaturated fatty acids, helps with the regulation and production of the thyroid and ensures proper function of the metabolism. Vitamin B12 helps to support every cell in the body by affecting the synthesis of fatty acids and the production of energy. Vitamin B12 is an essential supplement for proper digestion, protein synthesis, the absorption of foods and the metabolism of fat and carbohydrates. Incorporating these B-complex vitamins into the diet individually or together will provide complete nutrition for a healthy thyroid.
