Clinical Trial Summary

This study evaluates the effect of a multistrain probiotic on gastrointestinal (GI) complaints and diarrhoea in subjects receiving short-term antibiotic (AB) treatment

Description:

This study aims to investigate the safety and efficacy of live bacteria on gastrointestinal (GI) complaints and diarrhoea in subjects receiving short-term antibiotic (AB) treatment. The trial will be run in Germany and will recruit adult men and women.
