How Probiotics Promote More Positive Moods

The gut-brain axis is so crucial for optimal emotional and cognitive function that it's often referred to as "the second brain."  How does it work?  Studies show that bacteria in your gut send signals to the central nervous system, which creates streams of communication.  So the gut-brain axis is like a multi-directional super highway – each one representing intricate chemical signals and unique pathways between your digestive tract and the brain.  So what affects the gut, can also affects your brain.  Friendly microorganisms that reside in your digestive tract produce neurotransmitters that can affect your moods, sleep habits, and overall sense of well-being.  An example of an important neurotransmitter is serotonin, which has a wide range of functions in the body, and is called “the happy chemical” because it’s so vital for mood and overall wellbeing. While serotonin is necessary for healthy brain function, it's estimated that a staggering 95% of your serotonin is made in the digestive tract.

For example, research shows that a much higher than average number of people with irritable bowel syndrome also develop depression and anxiety.  And certain GI conditions and digestive problems can lead to stress, anxiety, depression and other mood disorders.  Your brain-gut axis runs in the other direction, as well.  For instance, when you feel frightened or like you’re in danger, your brain sends warning signals to the gut.  One instance is when you get butterflies in your stomach if you’re feeling nervous about a situation, or you feel nauseous during times of high stress -- that's your gut-brain axis at work.   

The good news is that probiotics may do much more than improve your gut health. Current research show that probiotics can promote better moods and cognitive function.  Foods and supplements containing these beneficial bacteria can play an important role in reducing anxiety, stress and depression, according to an analysis published in the journal BMJ Nutrition, Prevention & Health.  Researchers examined studies that involved probiotic therapy in depression and anxiety disorders. They found significant improvements in participant’s moods and other outcomes related to their mood disorders, even among people suffering from severe depression.  A study found that Alzheimer’s patients who drank milk containing four probiotic bacteria species for twelve weeks, scored higher on a test to measure cognitive impairment compared with those patients who drank regular milk.  Another study published in the journal Gastroenterology showed that women who regularly consumed yogurt that contained a mix of probiotics experienced more positive emotions when shown negative images with a control group.

The probiotic strains, Lactobacillus and Bifidobacterium, are the probiotic strains most commonly used to treat GI issues, but there are many probiotic products on the market that contain different types of bacteria.  The problem is not all probiotic supplements are created equal.
