Live Culture Gut Support That Works
The world of gut-focused supplements can feel crowded, confusing and oddly vague. Long ingredient lists, blends of half a dozen bacterial names, and big promises with very little clarity. As a customer, it’s hard to know what you’re really taking, or why.
At Better Guts, we decided there had to be a better way.
Founded in 2025 Better Guts set out with one simple mission: to deliver high-quality live culture supplements built around single, clinically studied strains, strains that are among the most researched in the world.
Clinically Proven Strains
For us, everything begins with the bacteria. Our starting point wasn’t packaging or flavour, it was the live cultures themselves. We carefully selected two strains that sit right at the centre of modern live bacteria research: LGG and BB-12.
Both were first discovered in the 1980s (LGG in 1983 and BB-12 in 1985). LGG was originally isolated from a human gut sample, while BB-12 was derived from traditional dairy cultures. This meant our bacteria were found in nature, not made in a lab. Since then, they’ve each been followed through decades of scientific work, with clinical research carried out by independent medical and academic teams across the world. These studies include children, adults and older people, across a wide range of ethnicities, diets and backgrounds, and the results consistently amazed us.
Once we mapped out the science, the choice was obvious. These strains have more published research behind them than almost any others, and they originate from nature rather than being artificially designed or modified. We knew we’d found a solid foundation for the kind of powerful live culture supplements we wanted to create.
Fibre For Complete Gut Support
We had a solid foundation with our strains of bacteria, but we wanted to make sure that once they get to your gut, they’re well fed. Only then can they really get to work!
Many supplements on the market lean heavily on artificial additives, synthetic fillers, unnecessary preservatives, flavourings and complex flow agents. We wanted to take a different path. Our formulas are built around prebiotic fibres, specifically FOS (fructooligosaccharides) and XOS (xylooligosaccharides), gentle, plant-based fibres derived from natural sources. These fibres are widely studied for how they interact with the gut environment and the bacteria that live there, including the strains we use.
In simple terms, they act like supplies for the bacteria, helping to create conditions in the gut that are more welcoming to both your existing microbes and the live cultures you’re taking. To support the blend further, we add a small amount of bamboo-derived silica, a plant-based ingredient that helps keep the formula consistent without introducing the kind of synthetic fillers we want to avoid.
The result was a clean formula we could be proud of, nature-derived fibres, carefully chosen supporting ingredients, and no unnecessary additives.
Delayed Release Technology
We had our formula, and we needed to make sure the delivery was perfect. It’s well known that stomach acid is harsh, and many live bacteria struggle to make it past that first stage of digestion. If a capsule opens too early, a significant proportion of its contents may not reach the gut in optimal condition.
To address this, we decided to use delayed-release capsule technology. These capsules are designed to remain intact as they pass through the stomach, resisting the effects of the acid, breaking down later in the digestive tract. This means that our live cultures can have the best chance possible to pass safely through the stomach for optimal delivery where they’re needed most, your gut.
No cut corners.
No compromises.
From strain selection to prebiotic fibres, from capsule design to the removal of unnecessary additives, every decision behind Better Guts has been made with care, evidence and integrity. There are easier ways to make a supplement, but we weren’t interested in cutting corners.
We’re here for people who want live culture supplements they can understand and trust: single-strain, science-led, and built with quality at every step.
