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 begin feeling full.
How might probiotics fit in the gut-brain axis? Some research has found that probiotics may help boost mood and cognitive function and lower stress and anxiety.
For example, a study published by Frontiers in Aging Neuroscience found that Alzheimer's patients who drank milk made with four probiotic bacteria species for 12 weeks scored better on a test to measure cognitive impairment compared with those who drank regular milk.
And a small study reported in the journal Gastroenterology found that women who ate yogurt with a mix of probiotics twice a day for four weeks were calmer when exposed to images of angry and frightened faces compared to a control group.
MRIs also found that the yogurt group had lower activity in the insula, the brain area that processes internal body sensations, like those emanating from the gut.
It's too early to determine the exact role probiotics play in the gut-brain axis since this research is still ongoing. Probiotics may not only support a healthier gut, but a healthier brain as well.

: Probiotics and brain function| The Gut-Brain Connection: How it Works and The Role of Nutrition | Probiotics won't usually boost cognitive functioning in younger people since "they're already performing at ceiling," Eastwood said. Davari S, Talaei SA, Alaei H, Salami M. In this Special Feature, we look at some of the top-level findings from the NutriNet-Santé study, the largest ongoing nutrition study in the world. Could probiotic supplementation improve cognitive function? Use limited data to select content. The most important prebiotics belong to carbohydrates and the family of galactooligosaccharides GOS , fructooligosaccharides FOS , and xylooligosaccharides 2. |
| Probiotic Bacteria Beneficial For Brain Function | 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-aminobutyric acid, all of which play a key role in regulating mood. 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 flip side, flares 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. In particular, researchers have looked at stress in students as they prepared for exams, while also evaluating other health indicators such as flu and cold symptoms 1. In healthy people, there is an indication that probiotic supplementation may help to maintain memory function under conditions of acute stress. A study by Meyer et al. This study also indicated that butyrate plays a role. Butyrate is a metabolite of several beneficial bacteria. Animal studies have shown that butyrate protects against cognitive impairment, vascular dementia and metabolic risk factors that contribute to cognitive decline and dementia. As noted above, butyrate production has also been linked to improvements in major depressive disorder symptoms 1. A review was conducted by Eastwood et al. The review found a positive effect of probiotics on cognition in 21 of 25 studies when the specific probiotic strain was administered as a therapeutic adjunct to people with conditions leading to impaired cognitive function. Species of specific probiotic strains that are most commonly connected with cognition, mental health and stress include Lactobacillus, Bifidobacterium, Lactococcus and Streptococcus. Prebiotics and postbiotics may also stimulate specific probiotics and beneficial bacteria that affect communications between the gut and the brain, and ultimately mental and emotional health. Now, scientists think that they might also slow down cognitive decline as we age, according to Jessica Eastwood, a nutritional psychology researcher in the department of psychology and clinical language sciences at the University of Reading in England. In younger people, Eastwood told Insider, probiotics might even help people perform better when they're stressed. Here's some of what we know about probiotics and brain health. Your gut and brain are closely connected, a partnership that's known as the " gut-brain axis. What affects the brain can affect the gut too, and vice-versa. That's why you might have butterflies in your stomach when you're nervous, Eastwood said. The connection is so strong that flares of GI conditions like IBS or Crohn's disease can set off mental health issues like depression or anxiety, according to Harvard Health. Scientists aren't exactly sure yet how these two systems work together. As we age, our cognitive functioning, which includes memory and executive functioning , naturally declines. Eastwood and her team published a review which found that taking a daily probiotic might reduce cognitive decline in otherwise healthy older adults. Eastwood said that this might be especially beneficial as people continue to live longer. The review also found that a daily probiotic might help improve cognitive performance in older adults who have a mild cognitive impairment or have Alzheimer's disease. While these findings are exciting, Eastwood said that bigger and better research trials are needed. More recently, a study presented at the American Society for Nutrition meeting in July of this year that found that older adults who took a probiotic had cognitive improvement compared to those that took a placebo. Probiotics won't usually boost cognitive functioning in younger people since "they're already performing at ceiling," Eastwood said. But "where you do see an effect in younger adults is if they are stressed. Sometimes, Eastwood said, if you're stressed, your cognitive performance goes down. |

The concept of bidirectional communication between the gut and the brain is well accepted, and is referred to as the gut-brain-microbiota axis. Early-stage studies to investigate the relationship between the gut microbiota and the brain have included mode of action studies, animal studies, preclinical work, and clinical studies.
