Brief summary

Participants experiencing recurrent gastrointestinal symptoms in this double-blind, randomized, controlled trial will receive either a commercially-available probiotic dietary supplement or placebo. The investigators hypothesize that participants in the probiotic dietary supplement group will experience greater improvement in their gastrointestinal symptoms than participants in the placebo group.
