| 0:00.0 | Today on the show, I'm joined by Kieran Krishnan, a research microbiologist and one of the world's leading experts on the human microbiome and the gut brain connection. |
| 0:10.6 | As the scientific mind behind Just Thrive Health, Kieran has spent over 20 years uncovering how gut health affects everything from mental clarity and mood to immunity, inflammation and burnout. |
| 0:23.5 | Together, we explore the latest science on how your gut actually talks to your brain, |
| 0:27.9 | what's sabotaging your mental resilience without you even realizing it, |
| 0:31.7 | and why not all probiotics are created equal? |
| 0:35.3 | In fact, most don't even survive your stomach acid. If you are ready for real |
| 0:40.2 | research-backed solutions, not just wellness fluff, this episode is your guide. |
| 0:56.7 | Kieran, welcome to the podcast. |
| 1:00.9 | I'm very excited to talk about this because I've just released a book called Help in a Hurry. |
| 1:01.2 | And I have a whole chapter where I talk about the fact that when we're angry how all |

| 1:18.0 | this podcast so much about the psycho-neurobiology of our humanity, so mind, brain, body connection |

| 1:29.1 | them working together and what people don't often realize is that your memories are stored |
| 1:35.0 | throughout the brain and the body and in the mind and so therefore our gut is also storing memories |
| 1:40.6 | and our gut is you the expert you're going to tell us more. I mean, our gut's got as many |
| 1:44.4 | neurons as the spinal cord. So we definitely hear a lot about the gut and a lot about microbiome and |
| 1:51.1 | all that kind of thing. And I'm so happy that we're going to unpack this together today. So welcome |
| 1:55.7 | to the show. And I can't wait to dive in. Thank you so much for having me. It's a pleasure to be here. |
| 2:01.7 | And these topics are so relevant. People are dealing with these issues every single day. |
