No Guts No Glory Probiotics

The goal of this clinical trial is to learn if probiotics work to prevent or reduce metabolic side effects caused by antipsychotic medication in adults. The main question it aims to answer is: Do probiotics reduce weight gain, blood sugar levels, and blood fat levels in people using antipsychotics? Researchers will compare a probiotic (Ecologic® Barrier) to a placebo (a look-alike powder without active bacteria) to see if the probiotic is effective. Participants will: Take either probiotics or a placebo daily for 12 weeks (3 months) Dissolve two sachets in water and drink them each morning Visit the clinic (or receive home visits) four times: at the start, after 6 weeks, and after 12 weeks, plus an initial screening visit Undergo physical measurements (e.g., weight, blood pressure), complete questionnaires, and perform a cognitive test at specific visits Provide blood samples and stool samples at the beginning and end of the study Complete two 3-day food diaries during the study
