[Probiotics]

Abstract

On the basis of the currently available literature, which includes well-designed clinical trials, systematic reviews and meta-analyses, certain effects can be ascribed to probiotics as a general class. It is accepted that sufficient evidence has accumulated to support the concept of benefits of certain probiotics; it is reasonable to expect that evidence gained from a defined class of live microbes might be appropriate for certain, but not all, health outcomes. Moreover there is a need for clear communication to consumers and health-care providers of the activity of differentiate probiotic products.
