Summary

This trial will test whether taking a probiotic supplement helps people with bipolar depression who have been recently hospitalized.

Who is the study for?
This trial is for adults aged 18-65 who have been hospitalized for bipolar depression and can visit Sheppard Pratt Towson post-discharge. Participants must be fluent in English, able to consent, and diagnosed with Bipolar Disorder I or II. Exclusions include other mental disorders, substance abuse, significant medical conditions affecting the brain, pregnancy/breastfeeding women, recent investigational drug use or ECT treatment.
What is being tested?
The study aims to see if a probiotic supplement can prevent relapse in individuals recently hospitalized for bipolar depression compared to a placebo (an inert compound). The goal is to improve their clinical outcomes after discharge from the hospital.
What are the potential side effects?
While not specified here, common side effects of probiotics may include digestive discomfort such as gas or bloating. Placebos typically have no active ingredients but can cause side effects based on participants' expectations.
