First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether a daily probiotic supplement (Antrrix) can reduce the frequency and severity of respiratory infections in children under 6 who get sick often. Over 8 weeks, 120 kids will receive either the probiotic or a placebo. Researchers will track symptoms and quality of life, and also analyze gut bacteria to understand how the probiotic might work.

What this could mean

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

Active substance

Antrrix probiotics (Lactobacillus rhamnosus CRL1505 and Bifidobacterium brevis M-16V)

What this could lead to

If it works, this could point toward a simple probiotic supplement to help young children have fewer and less severe respiratory infections.

What could go wrong

This is an early phase 2 trial with only 120 children, so results may not apply to all kids. Probiotics may not work for everyone, and the study is too small to confirm safety or effectiveness.
