In Podcasts by Danny LennonLeave a Comment

In this episode the Sigma team discuss the research looking at 'psychobiotics'; i.e. probiotics that have health impacts on those with pyschiatric disorders or symptoms. They discuss the origins of the research, the gut-brain axis, mechanisms by which gut microbiota could impact mood, and then the human trials to date that have examined probiotics' effects on mood, anxiety, depression, bipolar disorder and other outcomes.
