Your gut and your heart are connected to your brain via the vagus nervous system and 95% of serotonin is produced in the gut. Serotonin is the hormone that gives instructions to the body, for example, when to be happy, positive and in a good mood. The gut-brain axis (GBA) consists of bidirectional communication between the central and the enteric nervous system, linking emotional and cognitive centers of the brain with peripheral intestinal functions. There are both good and bad bacteria in the gut because the gut is connected to the brain and 95% of the instructions for movement is produced inside the gut.
