Preventing colds in kids with a probiotic
Part of Infections, Lungs & breathing clinical trials.
This trial tests if a daily probiotic (Lacticaseibacillus rhamnosus CRL1505) can help prevent upper respiratory infections (like colds and sore throats) in healthy children ages 3 to 12. If your child often gets sick, this supplement might reduce how often they catch a cold.

This trial tests whether taking probiotics can help young children recover faster from common colds. If your child has a mild or moderate cold and is not taking other probiotics, they may be able to join.
This trial tests if a daily probiotic can help young children who get frequent respiratory infections like colds and coughs. It aims to see if the probiotic reduces how often infections happen.
This trial tests whether a probiotic drink can help children aged 4-17 feel better when they have a cold or other upper respiratory infection. The probiotic contains two types of healthy bacteria that might reduce symptoms like coughing, fever, and a runny nose.
This study tests whether a probiotic supplement (a type of 'good bacteria') can help boost your immune system and reduce how often you get colds. If you are a teacher who frequently catches colds, this might help you feel better and miss fewer work days.
