Probiotics and mood


This post is part of the 100 Days Project
Day 23
In a previous blog post I mentioned in passing that I when I take probiotics, my mood (especially anxiety) is noticeably, if subtly improved.  The amazing thing about this to me is that I had no idea that gut and mood are linked before I started taking the probiotics.  I was puzzled as to what had happened until I went googling and found articles summarising recent research findings on the subject.  It's therefore unlikely my observations were due to the placebo effect.  
Lactobacillus acidophilos Rosell-52 and Bifidobacterium longum Rosell-175 have been cited in a French trial report as reducing anxiety.  This occurs because the bacteria release neurotransmitters including serotonin, dopamine and gamma-Aminobutyric acid.  The gut has been called the 'second brain' because the enteric nervous system which runs it requires significant amounts of these neurotransmitters, but once in the system, they also have an affect on our 'first brain' and thus our moods.
Today I purchased a bottle of a more complete probiotic than I've taken before.  It has more of the bacteria likely to improve mood.  I'm interested to see what the results might be.
