What is L. reuteri?

L. reuteri, or Lactobacillus reuteri, is a type of microbiota that has been studied for its potential health benefits. In the context of research using mouse models of autism spectrum disorder, L. reuteri has been observed to correct social deficits associated with autism. This effect is achieved by activating the vagus nerve, which in turn stimulates the release of dopamine and oxytocin. It's important to note, however, that these findings are based on animal models and thus should be approached with caution when considering their applicability to humans 1 .
