About this study

Official title: A Randomized, Double-blind Controlled Trial to Assess the Impact of Probiotic on the Intestinal Health of Individuals

The goal of this clinical trial is to evaluate whether daily supplementation with the probiotic Bifidobacterium breve BBr60 can improve metabolic, gastrointestinal, and emotional health in healthy adult volunteers aged 19 to 45 years.

The main questions it aims to answer are: Can B. breve BBr60 improve lipid metabolism (e.g., increase HDL and reduce total cholesterol) in healthy adults? Can B. breve BBr60 alleviate gastrointestinal symptoms and improve emotional well-being in a non-clinical population? Researchers will compare a BBr60 supplementation group to a placebo group to see if the probiotic group experiences greater improvements in metabolic, gastrointestinal, and psychological indicators.

Participants will: Take one sachet daily of either B. breve BBr60 (10 billion CFU) or placebo for 8 weeks. Provide blood and stool samples at baseline and week 8. Complete validated questionnaires assessing alcohol dependence, gastrointestinal symptoms, and emotional status.
