Probiotic strains

Discover the power of BioGaia’s probiotic strains

BioGaia takes pride in offering probiotics founded upon some of the world’s most extensively documented probiotic strains.

We continually push the boundaries of scientific and clinical research to enhance our understanding and bolster the efficacy and safety of our strains. Through rigorous scientific investigations and ongoing clinical trials, we are not just advancing science, we are shaping the future of the probiotics market and improving the quality of life of people all over the world.

Investing in science is at the core of our mission. From comprehensive clinical trials to cutting-edge global research in collaboration with top universities worldwide, we spare no effort to ensure the quality and effectiveness of our probiotic strains. As leaders in human health probiotics, we are dedicated to elevating the standards of the industry.

What is a probiotic strain?

Bacteria are classified according to their genus, species, and strain. Therefore, a probiotic strain is a very specific type of bacteria.

Bacteria are categorized into different groups based on their genus (similar to literary genres), species (like authors within those genres), and then even further into strains (akin to individual books by those authors). To illustrate this, imagine a vast library representing the bacterial world. Each section of the library corresponds to a different bacterial genus, similar to how different genres represent different types of literature. Within each genre (genus), you have various authors (species) who write unique books (strains). For instance, in the fantasy genre (genus), there might be the author Lewis Carroll (species), known for his famous work, “Alice in Wonderland” (strain). Just as “Alice in Wonderland” is distinct from other works written by L. Carroll, a probiotic strain is distinct from other bacteria within its genus and species. So, when we talk about a probiotic strain, we are referring to a very specific type of beneficial bacteria with unique characteristics and potential health benefits. It really is the strain that counts, when counting on the quality of the probiotic supplement.

Different probiotic strains have different effects

Probiotic strains, identified by genus, species, and a unique code (Limosilactobacillus (genus) reuteri (species) DSM 17938 (strain)), have different effects on our health.

The genetic variation among probiotic strains contributes to their diverse functionalities and health benefits, making each strain unique in its potential impact on human health. While various probiotic supplements contain bacteria categorized under the same genus and species, the specific strain matters most. Different strains of Limosilactobacillus, for example, can have vastly different effects on health.

The world’s safest and most studied probiotic strains

BioGaia leads the science of probiotics with Limosilactobacillus reuteri (formerly Lactobacillus reuteri).

Our granted patented strains of L. reuteri stand as some of the most extensively researched probiotics globally and have garnered scientific acclaim worldwide. The efficacy and safety of BioGaia’s formulations have been rigorously examined in over 250 published clinical studies involving approximately 22,000 individuals across all age groups.

Clinically proven safe for all ages

L. reuteri from BioGaia, has been widely studied in clinical trials and has been shown to have probiotic, health-promoting effects in both children and adults. Numerous studies and meta-analyses have verified the safety of our L. reuteri strains for human consumption among individuals of all ages. Through our extensive research, our products have been consumed at a dose of 10 billion CFU per day — which is 1,000 times the recommended daily dose— and no serious side effects were observed.

A relationship rooted in the timeless wisdom of human evolution

Limosilactobacillus reuteri (L. reuteri) is a remarkable species of bacteria with deep evolutionary roots. Over millions of years, humans and our ancestors have co-evolved with specific strains of L. reuteri. This evolutionary relationship underscores the significant role L. reuteri plays in human health. From birth, humans encounter L. reuteri during delivery and breastfeeding, initializing a symbiotic relationship crucial for infant digestion and immune system development. As we journey through life, if nourished, these bacteria continue to contribute significantly to our well-being. They help bolster immune responses and secrete molecules, promoting a diverse microbiota while inhibiting pathogen growth. Maintaining a robust gut microbiota becomes increasingly vital with age, as bacterial diversity diminishes.

The impact of modern lifestyle

Unfortunately, modern lifestyles have disrupted this delicate balance. Factors like low-fiber diets, stress, antibiotic usage, and even caesarean deliveries have led to the depletion of L. reuteri in the gut microbiota of humans. Scientific research confirms this and reveals that people living modern, bustling lives in the USA had zero percent of L. reuteri found in their gut microbiota, whilst tribal communities living a life close to nature in Papua New Guinean, were found to have 100 percent L. reuteri as part of their microbiota. Clearly, modern lifestyle causes vast changes to the human microbiota. The consequences of this disruption reverberate throughout our health and well-being, underscoring the importance of restoring this critical bacterial ally.

We restore the potential of the human microbiota

Thankfully, we can reintroduce L. reuteri to the human microbiota through BioGaia probiotics. By reintroducing L. reuteri through targeted probiotic solutions, we embark on a journey that reconnects us with the evolutionary forces that have shaped our species.

Reintroducing L. reuteri to our body

From infants to adults, our probiotics cater to every stage of life, returning the human microbiota to its intended balance, unlocking its potential to support digestive health, immune function, and the maintenance of optimal health. Also, it is essential to replenish these bacteria frequently with regular supplementation, as they are continually washed out of the gastrointestinal tract.

By supplementing with L. reuteri probiotics, we are not simply adding something new, but rather rekindling an ancient partnership. We’re providing our biological entity (our body) with a familiar friend, one that our digestive systems are evolutionarily primed to work alongside and enable the potential for optimal human health.

Next-generation probiotics (NGPs)

Next-generation probiotics (NGPs) represent cutting-edge science in health and wellness. Empowered by new technologies, our researchers are unlocking the potential of these previously uncultivable powerhouses.
