An infant probiotic global sensation
In 2004, BioGaia® introduced the world’s first probiotic oil drops, a pioneering innovation in probiotic delivery.
These drops were designed to offer a convenient way to incorporate friendly bacteria into daily routines, especially for newborns and infants.
Since then, over 100 million BioGaia® L. reuteri Protectis® Baby Drops have been sold around the world. In the UK, they have become a parenting favourite, winning multiple awards.
In 2025, Baby Drops received a ‘badge of approval’ from Made for Mums! We couldn’t be prouder.
What is Limosilactobacillus reuteri?
Limosilactobacillus reuteri (formerly known as Lactobacillus reuteri) is a probiotic bacterium that has co-evolved with humans since the beginning of time, and because of that it is adapted to its host. L. reuteri is one of the first bacterial species to naturally become established in the microbiota of the new-born.
BioGaia’s probiotic products with L. reuteri are among the most scientifically well-documented probiotics in the world in terms of both efficacy and safety. To date, over 220 clinical studies with BioGaia’s L. reuteri-strains have been performed in approximately 19,000 people of all ages.
FAQ
Probiotics are defined as ”live microorganisms that, when administered in adequate amounts, confer a health benefit on the host.” (WHO/FAO 2002, Hill C et al. 2014). An important criterium for qualifying as a true probiotic is that health benefits have been proven in clinical studies. Furthermore, a probiotic product must contain the same bacterial strain(s) and the same dose that was used in the clinical studies.
Even an indigenous bacterium like Limosilactobacillus reuteri (formerly known asLactobacillus reuteri) should be taken on a regular basis, since most people of modern society does not get colonized by L. reuteri during infancy. The epithelial lining covers our gastrointestinal tract and works like a skin on the inside of our bodies. The main task of our ”inner skin” is to differentiate between what should be absorbed and what should not be let into our bodies. Biopsies have shown that L. reuteri is temporarily binding to our epithelial lining. However, since the cells in our epithelial lining is replaced every fourth day, the majority of L. reuteri cells are also washed away within a week or so. Since L. reuteri colonization is transient, every day intake is recommended to ensure adequate and stable levels of L. reuteri in the gastrointestinal tract.
The recommended dose of a probiotic does not depend on bodyweight. BioGaia’s clinical studies show efficacy with the same dose both in children and adults.
