Summary

This study is testing whether a daily probiotic called Bacillus coagulans SNZ 1969 can help healthy children ages 6 to 12 have fewer and less severe colds, flu, and stomach bugs. One hundred kids will take either the probiotic or a placebo every day for 84 days during the cold and flu season. Researchers will track symptoms, immune markers in blood and saliva, and changes in gut bacteria.

What this could mean

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

Active substance
Bacillus coagulans SNZ 1969 (a probiotic)
What this could lead to
If it works, this could offer a simple, daily supplement to help healthy kids have fewer and milder colds and stomach bugs during the school year.
What could go wrong
This is a small, early-stage trial in healthy children, so results may not apply to everyone. Probiotics can sometimes cause mild digestive upset, and the benefit may be small or no different from placebo.
