Study Summary
The purpose of this study is to determine if daily consumption of a probiotic in the period before, during and after academic exams will help maintain digestive and immune health and quality of life of undergraduate students.

The symptom intensity from the 9 cold/flu symptoms will be summed to obtain a symptom intensity score. A symptom intensity score of \>6 will be designated as a day of cold. The mean proportion of days without a cold/flu will be compared between each probiotic and the placebo.
