[The probiotic yogurt Activia shortens intestinal transit, but has not been shown to promote defecation].
Activia is a yogurt product containing the probiotic bacterium Bifidobacterium animalis DN-173 010. Five clinical trials have been carried out. Four of these show that dairy products containing this bacterium shorten intestinal transit in volunteers. However, except in a subgroup of 19 out of 267 patients in one study, no significant effect of Activia was reported on the frequency, quantity or consistency of stools. In its marketing in the Netherlands, the company that produces Activia, Danone, claims that Activia promotes defecation. There is insufficient scientific evidence to support this claim.
