L. reuteri reaches the gut alive

Probiotics originating from humans, like L. reuteri, are unique, as they have biologically evolved within us, potentially fostering a more symbiotic relationship with our gut microbiota.

Live bacteria must survive the journey through the acidic environment of the stomach to reach the gut alive. Our exclusive L. reuteri strain is shown to survive stomach acidity and reach the gut alive.
