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.
