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

1:35.0	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.
