**DR. MAYA CHEN:**  

Hello and welcome to *Elemental Essentials*, the podcast where we explore the invisible chemistry that powers our everyday lives. I’m your host, Dr. Maya Chen, and today we’re diving into the periodic table to uncover seven essential elements that your body absolutely cannot live without: calcium, iron, magnesium, oxygen, iodine, copper, and zinc.

These aren’t just abstract symbols on a chart—they’re active players in your heartbeat, your thoughts, your immune system, and even your ability to take your next breath. We’ll look at where they sit on the periodic table, what they do in your body, and what happens when you don’t get enough of them.

So grab your favorite drink—maybe one fortified with some of these very elements—and let’s get elemental!
