Microbiome: Brain-Gut Connection How Probiotics Boost Mood & Cognitive Function


Probiotics do more than improve your gut flora health. They also may indirectly enhance your brain, too. Research shows that the gut and brain are connected, a partnership called the gut-brain axis.

The two are linked through biochemical signaling between the nervous system in the digestive tract, called the enteric nervous system, and the central nervous system, which includes the brain. The primary information connection between the brain and gut is the vagus nerve, the longest nerve in the body. The gut has been called a “second brain” because it produces many of the same neurotransmitters as the brain does, like serotonin, dopamine, and gamma-amino butyric acid, all of which play a key role in regulating mood.

In fact, it is estimated that 90% of serotonin is made in the digestive tract. What affects the gut often affects the brain, and vice versa. When your brain senses trouble—the fight-or-flight response—it sends warning signals to the gut, which is why stressful events can cause digestive problems like a nervous or upset stomach. On the upside, areas of gastrointestinal issues like irritable bowel syndrome (IBS), Crohn’s disease, or chronic constipation may trigger anxiety or depression.

The brain-gut axis works in other ways, too. For example, your gut helps regulate appetite by telling the brain when it’s time to stop eating. About 20 minutes after you eat, gut microbes produce proteins that can suppress appetite, which coincides with the time it often takes people to start feeling full.

These insights show you why the probiotic balance that maintains a healthy microbiome is so important. Easiest way to make sure your gut is healthy? Probiotic supplements.  They work.
