Dosage and colonisation

Colonisation in terms of probiotic supplements refers to the process by which beneficial 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 proven to survive the harsh acid environment of the stomach. It is one of few probiotics in the world that has been shown in a published clinical trial to significantly, however temporarily, colonise the stomach, duodenum and ileum of healthy humans in situ.

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 and stable level of probiotics in your gut.

Safety record

BioGaia’s products are safe 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 beneficial bacteria. BioGaia’s probiotics can help reintroduce and maintain L. reuteri in the gut.
