Can probiotics calm a crying baby? new study investigates

NCT ID NCT05271747

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested two different probiotic supplements in 112 healthy infants diagnosed with colic to see if they could reduce daily crying and fussing. Babies received either a multi-strain probiotic or a single-strain probiotic for 21 days. The researchers also tracked feeding type, regurgitation, bowel movements, and parent anxiety to understand what influences colic symptoms.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Probiotic multi-strain formulation (Bifidobacterium longum CECT7894 and Pediococcus pentosaceus CECT8330) and probiotic single-strain formulation (Lactobacillus reuteri DSM17938)

What this could lead to

If successful, this could point toward a probiotic option to reduce crying and fussing in babies with colic, potentially easing stress for parents.

What could go wrong

This is a small, completed study with 112 infants, so results may not apply to all babies. Probiotics may not work for every case of colic, and individual responses can vary.
