Participants sought for study examining effects of probiotics on gut health and immune function.

Participants are sought for a study examining the effects of probiotics (health-promoting bacteria), delivered via yogurt smoothies or tablets, on gut health and immune status. We are looking for healthy, non-smoking adults who are not taking cholesterol-lowering medications. Subjects will be provided with 4 different probiotic supplements over the course of 16 weeks with several compliance breaks in between. At the completion of the study participants will receive lab results and compensation of $400.
