probiotics + prebiotics

Prebiotics are non-digestible fibers (like inulin, FOS, and GOS) that some gut bacteria ferment for fuel. Pairing them with a probiotic creates what scientists call a 'synbiotic.' The pairing is plausible and generally well tolerated, but evidence that the combination clearly beats either ingredient on its own is mixed and depends on the condition and the specific strains used.
