In otherwise healthy adults given _l. reuteri_ DSM 17938 at 5x10^8^ CFU daily for two months was not associated with any severe side-effects and was well tolerated. Increases in fecal _l. reuteri_ were minimal in this study and not significantly different than placebo, and immune parameters (lymphocytes, monocytes, dendritic cells) were unaffected.
