Essentials: How to Build, Maintain & Repair Gut Health | Dr. Justin Sonnenburg

Welcome to Huberman Lab Essentials, where we revisit past episodes for the most potent and actionable science-based tools for mental health, physical health, and performance. I'm Andrew Huberman and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine. And now for my discussion with Dr. Justin Sonnenberg. Justin, thanks so much for being here.

Great to be here. I am a true novice when it comes to the microbiome. So I'd like to start off with a really basic question, which is, what is the microbiome? I think, you know, just to start off with clarifying terminology, microbiome and microbiota quite often are used to refer to our microbial community interchangeably, and I'll probably switch between those two terms today. The other important thing to realize is that these microbes are um

not just in our gut, but they're all over our body. They're in our nose, they're in our mouths, they're on our skin. Basically anywhere that the environment can get to in our body, which includes inside our digestive tract, of course, is, you know, colonized with with microbes. And the vast majority of these are in our distal gut and in our colon. And so this is the gut microbiota or gut microbiome.
