Big effect

In a small trial, a probiotic quadrupled the odds of recovering from diarrhea within 72 hours — but the sample was just 48 children.

This large effect comes from a single small trial in Thai children, so while promising, it needs replication before generalizing.

Children with acute diarrhea given Lactobacillus reuteri were 4.4 times more likely to recover within three days compared to placebo. However, the study included only 48 children with mild dehydration in an outpatient setting, so results may not apply to all cases. No serious side effects were reported.

Where this fits in the evidence

This is among the first studies we've indexed on Lactobacillus reuteri DSM 17938 for Improved Recovery from Diarrhoea — treat it as an early signal until more research accumulates.
