Brief summary

The goal of this interventional clinical study is to study whether the consumption of QiMeiYan Probiotics in 25-35 young people with Mild irritable bowel syndrome (IBS Score 75 - 175) will reduce the frequency of Diarrhea. 140 eligible participants (70 males and 70 females) will be enrolled in two study sites and randomly assigned to two groups of products QiMeiYan Probiotics and placebo. All participants will consume assigned products once a day after meals and record the critical data such as photo of feces. Three site visits will be arranged and all clinical data will be captured and recorded into CTMS (Clinical Trial Management System) for statistical analysis. Researchers will compare the two groups to validate if the daily consumption of QiMeiYan Probiotics will reduce the frequency of Diarrhea in the study population.
