what is selenium

Selenium is a special mineral that your body needs to stay healthy. Just like you need tiny bits of vitamins every day, your body needs a little bit of selenium, too. Doctors say most people should get about 55 micrograms each day.

This tiny amount does big things—it works like a shield for your cells, keeps your heart healthy, and helps your brain work well even as you age. It’s also good for ensuring your thyroid gland does its job right and boosts your strength to fight off sicknesses.

If you eat the right foods, getting enough selenium is easy. You can find it in superfoods like Brazil nuts—they pack the biggest punch of selenium! It’s also in seafood, meats from animals’ organs (like liver), chicken, turkey, and bread made from grains.

But watch out; eating too much selenium can be bad news. If someone takes in way more than they’re supposed to—like if they go overboard with supplements—they might start shaking, lose hair, feel sick to their stomach, or be dizzy.

This small but mighty mineral doesn’t play nice with some types of medicine, either. Selenium can change how these medicines work or what side effects they have.

Knowing all this about selenium means you’re on track to keep yourself healthy by picking the best stuff to eat!
