Digestive Health7 Billion CFU† + 200 mg FOSDietary SupplementVegetarian Embo Caps® Protect your GI tract from top to bottom with the probiotic power of Swanson Probiotics L. Reuteri Plus. First identified in the 1960s by Gerhard Reuter, the German microbiologist after whom it would eventually be named, Lactobacillus reuteri is one of the most prevalent naturally occurring probiotic gut bacteria in the animal kingdom, playing a valuable protective role in many species of mammals and birds. In humans, L. reuteri has been found to deliver protective benefits for the entire digestive tract, from the mouth to the stomach to the colon. Each capsule of our L. Reuteri Plus contains an impressive 5 billion of these microscopic defenders, along with a generous supply of two other beneficial gut bacteria—L. rhamnosus and L. acidophilus—to bring you balanced, broad-spectrum probiotic support that no single-strain supplement can match. To nourish the organisms and help them thrive, L. Reuteri Plus also includes 200 mg of NutraFlora® scFOS® (short-chain fructooligosaccharides), a prebiotic fiber whose short-chain structure makes it the ideal food source for the beneficial bacteria in the intestinal tract. To ensure that the probiotic organisms safely reach the lower GI tract for optimal benefit, L. Reuteri Plus features vegetarian capsules that protect the contents from degradation by stomach acids. With a total of 7 billion viable organisms from three proven strains, nourished by prebiotic scFOS, L. Reuteri Plus delivers outstanding protection for your entire GI tract. †Contains total of 7 billion CFU (colony forming units) when manufactured and provides an effective level of bacteria until at least the "best by" date.
