Why BioGaia Products Are So Effective
The key to BioGaia’s success isn’t just marketing – it’s science.

Unlike many generic probiotic brands that just throw random strains into a capsule, BioGaia focuses on strains that have been tested for specific health benefits.

The Power of Lactobacillus reuteri
At the core of BioGaia’s success is its signature probiotic strain, Lactobacillus reuteri. This strain is special because it’s one of the few probiotics that naturally exist in the human body, meaning it works in harmony with our digestive and immune systems. Unlike some probiotics that pass through the gut without lasting effects, L. reuteri actually colonizes and supports long-term gut health.
