Dosage and colonisation
Colonisation in terms of probiotic supplements refers to the process by which friendly bacteria, like Lactobacillus reuteri, temporarily adhere to and grow in the gastrointestinal tract. This helps maintain a healthy balance of gut bacteria, promoting overall digestive wellness.
L. reuteri Protectis has been studied throughout the human GI tract with biopsies technique. All BioGaia probiotic supplements are shown to survive the harsh acid environment of the stomach. It is one of few probiotics in the world that has been shown to significantly, however temporarily, colonise the stomach, duodenum and ileum of healthy humans in situ.
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 fibre diets, stress, antibiotics usage, and environmental factors) it is naturally present in the body in very low numbers.
Daily intake of probiotics is necessary because these friendly bacteria are naturally expelled from the body within a week or two. Regular consumption ensures that you maintain an adequate and stable level of probiotics in your gut.
Safety record
BioGaia’s products are suitable for all ages, with no serious side effects observed.
Supporting gut health throughout life
Modern lifestyles, including stress and low-fibre diets, and other factors have led to a decline in friendly bacteria. BioGaia’s probiotics can help reintroduce and maintain L. reuteri in the gut.
