Clinical studies

Research on bacteria

In the past decade, research on bacteria and their significance to our health has increased. At BioGaia, we have been researching Limosilactobacillus reuteri (formerly Lactobacillus reuteri) for more than 30 years. During the years, we built a unique research network of specialists at research institutes worldwide. Together we have learned and gained knowledge about several L. reuteri bacteria strains for various conditions.
