Probiotics may help reduce sad thoughts and feelingsprobiotics for preventing depression and mood swings

It’s shown dwelling on the past can lead to depression. So researchers wanted to know if taking a multi-strain probiotic formula could keep people from staying stuck in the past. And therefore help prevent depression.

Psychologists Laura Steenbergen and Lorenza Colzato from the Leiden Institute of Brain and Cognition tested the theory on a group of 40 healthy adults. For 4 weeks, half of the group received the probiotics and the other half received a placebo.

At the beginning of the study, participants took a questionnaire showing their sensitivity to depression. Then they took it again 4 weeks later. At the end of the study, those receiving probiotics showed significantly lower focus on thoughts about the past.

Says Colzato, “Even if preliminary, these results provide the first evidence that the intake of probiotics may help reduce negative thoughts associated with a sad mood. As such, our findings shed an interesting new light on the potential of probiotics to serve as adjuvant or preventative therapy for depression.”
