What if the root of your symptoms isn’t in your head or your hormones, but in your gut?

In this episode, I sit down with Kiran Krishnan, microbiologist and founder of Microbiome Labs, to explore why the gut is so much more than a digestive system. It’s the control center for your mood, your energy, your hormones, and your healing.

Kiran breaks down how the gut and brain communicate, why stress disrupts your entire microbiome, and what most people get wrong about probiotics. We also explore the surprising role of fiber in longevity, how early morning light sets your gut rhythm, and why sometimes the simplest habits are the most powerful medicine.

This conversation is a grounded, science-backed invitation to stop fighting your body, and start supporting it. Because when you understand your gut, you understand yourself.

Kiran Krishnan is a research microbiologist and co-founder of Microbiome Labs. He has spent his career studying the gut-brain axis and helping people shift from symptom management to root-cause healing. Through his work, Kiran empowers people to trust their body’s intelligence and embrace daily rituals that create lasting balance.
