Probiotics are all the buzz these days as gut health is rapidly becoming one of the most widely discussed topics when it comes to optimal health. Nearly the entire immune system is located in the gut making gut health foundational in achieving optimal health. It seems as though probiotics are popping up everywhere from beverages to cereals as this topic gains popularity and more people look towards improving the health of their gut.

However, two recent studies published in Cell have people questioning the effectiveness of probiotics. In one study, researchers studied the changes in the microbiome of a group of people over the course of one month that were given an 11-strain probiotic combination or a placebo. In the second study, researchers, studied the effects of the same 11-strain probiotic after antibiotic use.
