Travelers’ Probiotic is a side effect–free solution for the symptoms of travelers’ sickness, which include diarrhea, nausea, abdominal cramps, vomiting, and bloating. Extreme cases can cause fever, chills, and bloody stools.

Travelers’ Probiotic is a unique formula that populates the intestines with the therapeutic amount of 10 billion live cells of the beneficial yeast Saccharomyces boulardii. S. boulardii is a transient yeast which crowds out harmful bacteria that cause travelers’ sickness and neutralizes their toxins. This creates favorable conditions for the 11 billion colony-forming units of 11 scientifically proven probiotic strains to restore the balance of healthy intestinal flora.
