Effect of Lactobacillus Casei Shirota on the Small Intestinal Microbiota (ROBIN) (ROBIN)
The Effect of Daily Consumption of a Probiotic Drink Containing Lactobacillus Casei Strain Shirota on the Small Intestinal Microbiota in Healthy Male Subjects as Measured by the IntelliCap Sampling Capsule System.

Intervention / Treatment
Detailed Description
The study is a dietary intervention study with a repeated measures design, comparing the upper gastrointestinal microbiota profiles in healthy male subjects before and after consumption of a probiotic drink containing LcS.
This study is explorative in nature. This pilot-study is used to explore trends in microbiota profile shifts in the small intestine. In addition, the investigators would like to explore whether these microbial shifts are similar to those observed in fecal samples. Information derived from this pilot-study can be used to design future intervention studies focusing on either the effect of probiotics on microbial shifts in the small or large intestine.
