Why would you limit yourself only to probiotics when prebiotics/symbiotics exist? I recently learned about them - bear with me as I have zero experience and lack of terminology in pharma - prebiotics will create a better environment/surface for probiotics to feed on and symbiotics are both pre and pro in a single pill.

It isn't really clear that synbitoics work yet, the evidence for metabolic outcomes at least is sparse as of now http://www.mdpi.com/2073-4425/9/3/167/htm (see figure 6)
