Your gut isn’t just responsible for digestion it plays a major role in your emotional well-being, stress response, and overall happiness.

How Your Gut Talks to Your Brain
The communication between your gut and brain happens through the gut-brain axis a direct network of nerves, hormones, and biochemical signals. The most important of these is the vagus nerve, which sends constant messages back and forth between the two systems.
- 90% of serotonin (the happiness hormone) is produced in the gut.
- Gut bacteria create neurotransmitters that influence mood.
- Inflammation in the gut can trigger stress signals in the brain.
When your gut microbiome the trillions of microorganisms living inside you is balanced and healthy, it sends positive, stabilizing signals to your brain. When it’s unbalanced, it can produce anxiety, low mood, irritability, and fatigue.
