Paid Human Microbiome Research Participation Opportunity


Interested in participating in research about nutrition and gut health?

George Mason University is recruiting research participants for a study of a new prebiotic nutritional supplement. Prebiotics are soluble fiber food ingredients that stimulate the growth and maintenance of beneficial bacteria in the digestive system. Prebiotics have been shown to have a positive impact on health and wellness. We are trying to measure the effect of a particular prebiotic nutritional supplement on beneficial bacteria.

We are recruiting research participants for a randomized study of a daily dose of the prebiotic or placebo for eight weeks. Individuals who are between the ages of 18 and 45 years, have a maximum weight of 350 pounds, have a body mass index of 25 or higher, and are in good health are eligible to participate. Participation will involve taking a daily prebiotic supplement, completing questionnaires, and collecting stool samples four times and returning them to the university.

Participants will be paid a stipend of $235 for completion of all study requirements.
