- Serotonin, which regulates mood and emotion, is largely produced in the gut (about 90%).
- The vagus nerve, the primary channel between the gut and the brain, sends signals in both directions, allowing the gut microbiome to influence mental states.
- Dysbiosis, or an imbalance in gut bacteria, is associated with mental health disorders like depression and anxiety.

The relationship between the gut and brain, known as the gut-brain axis, has become a crucial area of research in neuroscience and gastroenterology. Emerging studies reveal that the gut and brain communicate bidirectionally through a complex network of nerves, hormones, and biochemical signals. Your digestive health plays a vital role in cognitive function, mood regulation, and even mental disorders such as depression and anxiety.
