Meet L. reuteri DSM 17938

Over 250 clinical studies

BioGaia’s probiotic supplements with L. reuteri are among the most extensively studied in the world. Over 250 clinical studies involving around 22,000 people have documented the efficacy and safety of BioGaia’s different strains of L. reuteri.

All BioGaia products contain L. retueri.

An introduction to Limosilactobacillus reuteri (formerly Lactobacillus reuteri)

L. reuteri is a unique species of bacteria that is grounded in evolution. It naturally inhabits the gastrointestinal tract (GI) and is passed down from generation to generation. Over millions of years, humans have co-evolved with our own specific strains of L. reuteri.

As a result of this evolutionary process, L. reuteri contributes to human health. When we are born, our gut microbiota is almost sterile. However, we first encounter L. reuteri during birth and breastfeeding. As a member of the gut microbiota, L. reuteri plays an important role in helping babies digest breast milk and solid food.

Reintroducing L. reuteri through probiotics

Throughout life, bacteria tighten the lining of the gut to prevent leakage and improve immune response. Furthermore, they release molecules that promote a healthy and diverse microbiota and prevent the growth of pathogens.

The gut microbiota needs to be supported, especially as we age since the diversity of bacteria decreases when we get older.

While some people today still have L. reuteri in their microbiota, most people lack these species due to our modern lifestyle. The vast depletion of L. reuteri from our gastrointestinal tract has been attributed to low-fiber diet, increased sanitation and antibiotic use.

Luckily, L. reuteri can be reintroduced through probiotics, but they must be consumed frequently since the bacteria are constantly washed out of the GI tract.

One of the most clinically researched probiotics

BioGaia’s probiotic supplements with L reuteri are among the most clinically researched probiotics in the world, with over 600 granted patents:

The unique properties of Limosilactobacillus reuteri (Lactobacillus reuteri)*

• Co-evolved with humans, naturally present in the body
• Survives the acidic environment of the stomach
• Proven to temporarily colonize the entire gastrointestinal tract
• Promotes a balanced microbiota
• Safe for all, from newborns, pregnancy and the elderly
• One of the world’s most studied probiotic

Why daily intake of L. reuteri matters

Whilst L. reuteri has co-evolved with humans since the dawn of time, through the impact of modern living (low fiber diets, stress, antibiotics usage, and environmental factors) it is naturally present in the body in very low numbers.

Also, daily intake of probiotics is necessary because these beneficial bacteria are naturally expelled from the body within a week or two. Regular consumption ensures that you maintain an adequate level of L. reuteri in your gut.
