Lactobacillus reuteri is one of the few indigenous *Lactobacillus* species in humans, naturally colonizing the gastrointestinal tract and evolving with its hosts over time. Numerous studies have shown that this beneficial bacteria offers a range of potential health benefits, from digestive support to immune system regulation. This guide explores the scientific evidence behind the diverse health benefits of Lactobacillus reuteri, highlighting its importance for overall wellness.

Historically, Lactobacillus reuteri was mistakenly classified as a member of Lactobacillus fermentum before being recognized as a distinct species in 1980. Although once considered the same, genetic analysis proves that Lactobacillus fermentum and reuteri are different, with unique characteristics and probiotic effects.

Though once naturally common in the human digestive tract, modern diets and lifestyles have significantly reduced the prevalence of *Limosilactobacillus reuteri*, now known as reuteri. This beneficial bacterium can still be found in several fermented food products and is a key component of breast milk, underscoring its historical role in human gut health.
