Probiotic Snack Bar
Great Lakes Clinical Trials is looking for male and female volunteers between the ages of 18 and 65 for a investigational research study involving the consumption of a daily snack bar. Participants will be randomly assigned to consume either a standard snack bar or a snack bar containing a probiotic for a 4 week period.

The purpose of the study is to measure levels of the probiotic that pass through your gut and appear in your stool. The study will require you to collect your stool on 4 separate occasions throughout the 6-week study period.   You will be provided with a stool collection kit and transport systems.

You will be asked to visit our clinic on 6 occasions over approximately 6 weeks.  One visit is simply to drop off a stool sample.  The other 5 visits last between 30-90 minutes.


There is no cost for participation in this study. All medications, tests and doctor visits are free of charge and we do not bill insurance. For your participation, you will receive $25 for visits 1, 2 & 3 and $75 for visits 4, 5, and 6, for a total of up to $300 for completing the trial.
