Study finds probiotics might not be as helpful for the intestine

The video discusses a study on probiotics, revealing that they often have little effect inside the body. Researchers created a probiotic cocktail using 11 types of bacteria, including Lactobacillus and Bifitobacteria, to test their colonization in healthy intestines. Participants were divided into two groups, one receiving the probiotic cocktail and the other a placebo. Results showed that in half the cases, probiotics passed through the body without effect, while in the other half, they temporarily colonized before being displaced by existing microbes.
