Human Gut Microbiota and Prebiotic Response
Study Details
Study Description
Brief Summary
This study is designed to examine the shift in gut microbiota and their metabolism after consumption of a dietary supplement (prebiotic) by healthy participants. The investigators will provide participants with a panel of over the counter prebiotics and monitor their gut microbiome response in stool. All prebiotics will be commercially available, over-the-counter food, food additives, or dietary supplements, without any known market-use adverse effects beyond minimal discomfort.
