Top 10 Best Probiotic Strains to Combat Infectious Diarrhea

Let’s face it, no one looks forward to a bout of infectious diarrhea, yet we’ve all faced it. Diarrhea is defined by the World Health Organization as three or more loose or watery stools in a 24-hour period. The condition is caused by approximately 20 different infectious agents including bacteria, viruses and parasites. In the United States, episodes of infectious diarrhea occur in children an average of two times per year. In addition, foodborne diarrheal illness results in approximately 48 million cases per year, resulting in 128,000 hospitalizations ( ).

Infectious diarrhea typically resolves in three to seven days and the main risk to your health is dehydration and so it’s important to remain hydrated. However, hydration alone will not shorten the duration of the illness, nor will it limit stool volume. There is strong consensus that probiotics are effective in limiting the duration of infectious diarrhea. In a meta-analysis of 63 trials and 8,014 people, many of whom were infants and children, researchers showed that probiotic therapy shortened duration of diarrhea by 25 hours and reduced stool frequency

Here’s my short list of probiotics that have been tested and clinically shown to reduce the duration of diarrhea. Click on the links under the reference section to access the scientific literature.
