Certain single strain (Saccharomyces boulardii, LGG, Lactobacillus reuteri, Bifidobacterium lactis, and ECN 1917) and multistrain probiotics can effectively treat acute diarrhea in children, reported a recent study

The key findings were as follows:

• L. reuteri and S. boulardii can reduce the duration of diarrhea, the risk of diarrhea lasting ≥2 days, and the mean stool frequency on day 2.
• Evidence with a low or very low certainty suggested that B. lactis, LGG, and ECN 1917 could shorten the duration of diarrhea.
• For multi-strain probiotics, Lactobacillus species (spp.) plus Bifidobacterium spp. plus Saccharomyces spp (L. spp. + B. spp. + S. spp) showed moderate evidence in decreasing the duration of diarrhea and the mean stool frequency on day 2.
• Only Bacillus spp. plus Enterococcus spp. plus Clostridium spp (Bacillus spp. + E. spp. + C. spp.) could reduce the duration of vomiting with moderate evidence.
• Saccharomyces boulardii (S. boulardii) was effective in reducing the duration of diarrhea (compared with placebo) and the risk of diarrhea lasting ≥2 days, with moderate evidence.
