5 Fascinating Facts About the Microbes in Your Gut

You may not realize it, but a thriving community of microbes is inside your body! Known as the microbiome, these bacteria and other microorganisms are essential to your physical and mental health. Let’s take a closer look at some surprising facts about the microbes in your gut.
