20 Dec 2018 --- Probiotics have been flagged as a potential avenue of treatment to alleviate bipolar and other psychiatric mood disorders, a Baltimore Sheppard Pratt Health System study has found. Published in Bipolar Disorders, the research showed that a probiotic supplement reduced inflammation, which is known to exacerbate bipolar disorder, in the gut of participants hospitalized for mania. Probiotic organisms are non-pathogenic bacteria that, when present in the gut flora, may improve the overall health of the host.
