NCT01519310

Brief Summary

The purpose of this study is to see if intestinal bacteria plays a role in choline metabolism (a form of choline monitored in this study is called phosphatidylcholine, also known as lecithin). This study will help to determine if choline metabolism is affected by short-term antibiotic therapy, and/or can be altered by probiotic therapy (e.g. in the form of eating yogurt).
