Selenium is a nutrient that the body needs to stay healthy. Selenium is important for reproduction, thyroid gland function, DNA production, and protecting the body from damage caused by free radicals and from infection.
But your body also needs small amounts of some other minerals. And we still donât know everything they do. Selenium is one of these âtrace minerals.â Your body uses it to make more than two-dozen enzymes. But we only know what half those enzymes do. But we do know selenium supports thyroid health. And since your thyroid gland controls your metabolism, getting enough selenium is critical. In one recent study, scientists compared 440 healthy people to 355 others with underactive thyroids.
