Support thyroid function

The thyroid gland is a tiny, butterfly-shaped gland located in your throat. It secretes a number of hormones that are necessary for development, metabolism, and temperature regulation. Selenium is abundant in thyroid tissue because it is essential for the creation of the thyroid hormone T3, as well as proteins that protect your thyroid from injury. Selenium deficiency can cause cellular damage, decreased thyroid activity, and autoimmune illnesses such as Hashimoto's thyroiditis and Graves' disease. It may also raise your chances of developing thyroid cancer.

People with low selenium levels had a much higher prevalence of thyroid illnesses, such as hypothyroidism, thyroiditis, and enlarged thyroid, compared to those with normal levels, according to one big study in China. This emphasizes the significance of receiving enough selenium. One Brazil nut per day should provide enough selenium to keep your thyroid functioning properly.
