Celebrating more than 30 years of probiotic innovation


Curiosity, perseverance, excellence
For over three decades, BioGaia has been on an incredible journey dedicated to exploring the fascinating world of probiotics.
What began as a quest to understand the intricate world of bacteria has evolved into a legacy of scientific excellence and consumer trust.
Our story is one of curiosity, perseverance, and a relentless pursuit of excellence. Here’s a glimpse into how our 30+ years of research have shaped the products you know and trust today.
The beginning: A vision takes root
Over thirty years ago, the founders and a small group of visionary scientists came together with a shared dream: to unlock the potential of friendly bacteria. They believed that these tiny organisms held the key to maintaining our everyday life.
And with this bold vision, BioGaia was born.


Pioneering research
In 1990, through meticulous research, a groundbreaking discovery was made.
BioGaia scientists discovered the unique qualities of L. reuteri, a probiotic species. The amazing L. reuteri became the cornerstone of our product line.
Limosilactobacillus reuteri (formerly Lactobacillus reuteri)
For 35 years, we have been researching L. reuteri. A probiotic naturally found in the human body, this remarkable bacterium has been co-evolving with humans since the beginning of time.
Every BioGaia product features strains of L. reuteri, which are carefully selected and make BioGaia products a trusted choice for probiotics of healthcare professionals and consumers alike.
Trusted worldwide
Our commitment to conducting rigorous research ensures that our products are science based and trusted worldwide.
BioGaia’s probiotic supplements are among the most extensively researched in the world.

Extensive global scientific network
At BioGaia, we believe in the power of collaboration, and our research is often conducted in partnership with leading universities, hospitals, and independent research organisations worldwide.
Our network includes: the Swedish University of Agricultural Sciences in Uppsala, Karolinska Institute in Stockholm, Sahlgrenska University Hospital in Gothenburg, Texas Children’s Hospital in the USA, and the University Hospitals of Bari and Turin in Italy.
These collaborations have enabled us to stay at the forefront of probiotic research and innovation.
You can trust that every BioGaia product comes with decades of research and a commitment to delivering the very best in probiotics.
How BioGaia’s innovation became a worldwide sensation
Over the years, our dedication to research has led to trailblazing discoveries.
In 2000, BioGaia developed the world’s first chewable probiotic tablet, a groundbreaking innovation that made probiotics easier and more enjoyable to consume.
The chewable tablet was designed in a convenient format, eliminating the need for swallowing pills or mixing powders.
Perfect for adults and children, our chewable probiotic quickly became a worldwide bestseller for its ease of use and great taste, revolutionising how probiotics are consumed around the world.
In 2004, BioGaia introduced the world’s first probiotic oil drops, another pioneering innovation in probiotic delivery. These drops were designed to offer a convenient and effective way to incorporate probiotics into daily routines, especially for newborns and infants.
Since its launch, over 100 million baby drop products have been sold.
