Figuring out which bacteria or other nutrients your gut needs may one day be as simple as running detailed computer simulations.

From pills to yogurts to sodas, probiotics are being repackaged and marketed to us more and more, with the promise of boosting our “gut health.” But while commercially available probiotics work for some people, this one-size-fits-all approach hasn’t reliably benefited consumers. Instead, new simulations can predict whether a specific bacterial strain will successfully take up residence in a person’s gut, researchers report February 19 in PLOS Biology.
