Selenium is an essential mineral[2] and being deficient can lead to serious health problems such as Keshan disease[3], myxoedematous cretinism[4], Graves’ disease[5], and even thyroid destruction.[6]

The thyroid is essential to some of the body’s most critical processes, including the development of the nervous and skeletal systems.[1] For the thyroid to function normally, it must receive the right nutrition, and that means getting enough selenium.

Although the body requires selenium, it does not produce selenium and you must get it through your diet. For most people, this isn’t a problem since many common foods are a good source of selenium. Additionally, selenium is available as a nutritional supplement.

Regardless of the source, selenium is a critical nutrient for the body and nowhere is this more evident than the thyroid. In fact, the thyroid has more selenium content per gram than any other organ. It’s also home to certain proteins called selenoproteins[7] which contain selenium-based amino acids. The importance of selenium for your thyroid cannot be overstated. Most people know that iodine is critical to thyroid health. Selenium is less famous but equally important. Along with iodine and vitamin A, selenium helps remove thyroid-harming substances and supports normal thyroid structure..[7]
