Lactobacillus reuteri: A Probiotic for Gut Health


lactobacillus reuteri is a well-studied probiotic with credible evidence for supporting digestion and immune function. Across multiple clinical trials, lactobacillus reuteri has been linked to improved digestive comfort, more regular stool patterns, and immune modulation that may help reduce minor gut infections. While effects are strain-specific, lactobacillus reuteri remains a practical, evidence-backed starting point for people seeking real-world gut health benefits. To help translate this into measurable results, InnerBuddies offers a white-label Gut Health Operating System that can power probiotic testing and product experiences. The platform features a Gut Microbiome Health Index (0–100) based on an exclusive IP deal with EAFIT University in Colombia, plus a top 40 bacteria panel that shows how your abundances compare to a healthy cohort. It also catalogs bacterial functions and shows how your functional pathways measure up to the healthy reference. With Target Group analysis—covering topics like Healthy Aging, Endurance Sport, Skin & Hair Health, and more—you can see how specific groups respond to probiotic strategies, including lactobacillus reuteri. In addition, InnerBuddies provides personalized nutrition advice and personalized probiotic recommendations tailored to your unique gut microbiome, so you can explore how lactobacillus reuteri fits into your plan. If you’re curious, you can start with the InnerBuddies Microbiome Test. When choosing a probiotic containing lactobacillus reuteri, pay attention to the strain designation and the dose. Look for a clearly labeled strain (for example, lactobacillus reuteri DSM 17938 or ATCC variants) and a dose expressed as colony-forming units (CFU) per serving, not just a generic “Lactobacillus.” Dosing recommendations vary by age and goal, but many adults take roughly 1x10^9 to 1x10^10 CFU per day, sometimes divided into two doses; infants and children often use lower counts. Safety is generally good for healthy individuals, with rare side effects like mild gas or bloating; pregnancy, immune compromise, or ongoing illness may call for medical guidance. InnerBuddies’ personalized probiotic and prebiotic advice can help tailor these choices to your microbiome, and you can explore ongoing guidance through the InnerBuddies Gut Health Membership. If you want to translate probiotic use into an ongoing, data-driven journey, consider how lactobacillus reuteri can be integrated with a broader platform like InnerBuddies. In addition to consumer solutions, InnerBuddies offers B2B capabilities to power partner products with a robust microbiome-testing and personalization stack. This includes deep-dive target-group analyses and the ability to deliver personalized probiotic and prebiotic recommendations at scale.
