Effect of a Probiotic on Anxiety/Depression through the Gut-Brain Axis

Abstract

The purpose of this study was to determine whether probiotic supplementation can display a positive effect on depressive or anxious measurements/symptoms. The bedrock of this project is whether a nexus exists between microbiome quality and robustness of mental health. Twenty-three individuals were ultimately included in the analysis with 11 in the placebo group and 12 in the probiotic group. Subjects ingested four capsules at the same time once a day at approximately the same time of day; this regimen endured for four weeks. Individuals completed the GIQLI before and after supplementation to gauge (mental) health quality. Both the probiotic and placebo groups experienced improvements in their mental health scores, though the difference between pre and post scores for the probiotic group was significant (p≤0.05). Current evidence suggests probiotics can serve as a beneficial remedy for emotional symptoms. Stetson University.
