Meet the ecosystem inside you ...

A timid Bifidobacterium named Biffy is forced to leave their family and become part of a new community, in the gut of a newborn human baby.

Follow Your Gut is a comic that ate a biology textbook. It's an epic adventure set over the first three years of a new life, exploring one of the most important relationships you will ever have--the one with your gut microbiome.

Created by artists, scientists, and educators, this story is for anyone who's curious about the human-microbe symbiosis, and what all those trillions of bacteria are doing down there in your intestines!

Inspired by the latest research, Follow Your Gut includes a fascinating and detailed appendix that explains the amazing science behind the story.

'A wildly entertaining science lesson that will change how you see your own body.' -- Dr Nat Bannan, high school science teacher
