Probiotics offer dietary means to support the balance of intestinal flora and they are often underestimated in their health benefits. Marteau et al (2001) state that "friendly bacteria" are "non-pathogenic micro-organisms that, when ingested, exert a positive influence on the health of the host". They may be used to stabilise the intestinal mucosal barrier function, prevent infection from pathogenic microorganisms and influence intestinal metabolism (Rolfe: 2000). Due to these actions, probiotics should be used during and after antibiotic use, during foreign travel, and to support your gastrointestinal health.
