Clinically Proven Strains
Live Bacteria backed by the highest standard in clinical research
Everything from Bloating and Cramping through to Diarrhoea, SIBO and IBS/IBD, these microbes have been clinically researched through it all.
Clinically Proven Strains
We understand why multi-strain blends are popular. They look impressive on a label, and the idea of “more strains must be better” is easy to buy into. But blends can also make it harder to know what you’re actually getting and what it’s supposed to do. When 10 billion CFU is split across 10–12 strains, the amount of each individual strain can be relatively small, and it’s rarely clear how that mix relates to the published research and what everything in there does.
Our single-strain formulas remove that confusion. With one strain per product, you can see exactly what’s in your capsule and look up the scientific literature for that specific microbe. It also keeps the formula more predictable: one strain, clearly named, in a clearly stated high CFU format, without a crowded list of Latin names and other unwanted extras.
Our two strains were first discovered in the 1980s and have been studied around the world ever since. They weren’t developed in a lab, they’re naturally occurring strains with decades of research and real-world use in real people behind them. Today, they’re often used as reference points in the wider world of live bacteria research because of how extensively they’ve been investigated and how much we know about what they can do.
High-strength, built for real-life routines
Better Guts is designed for people who want a daily routine that feels straightforward and reliable. That’s why our formulas are high-strength and clearly labelled. We use CFU levels that are commonly seen across published human research for these strains, and we keep the rest of the formula focused. There are no unnecessary extras, no complicated stacks of ingredients, no filler-heavy blends.
We believe that consistency matters more than hype. A supplement does its best work as part of a long-term routine, not a short-term fix. So we designed Better Guts to be simple, clean, and easy to stick with, whether you’re starting a new wellness routine or refining an existing one, it’s a simple addition with a powerful effect.
Prebiotic
fibres: support for the gut environment
The live cultures in our supplements are the main event, but the surrounding environment and what they go in with matters too. That’s why every Better Guts capsule includes plant-based prebiotic fibres: FOS (fructooligosaccharides) and XOS (xylooligosaccharides).
Prebiotics are fibres that your body doesn’t digest, but the microbes in your digestive system can use them as fuel. In simple terms, they help create a more supportive gut environment. We like the idea of sending live cultures in with the kind of ingredients that make the gut more welcoming, rather than dropping them into an environment with no support at all.
We keep this element of the formula gentle and purposeful. FOS and XOS are widely used in nutrition science and are typically well-tolerated by many people when used appropriately. They’re also plant-derived, which fits our approach of keeping it clean, simple, and plant based.
To round out the formula, we use a small amount of bamboo-derived silica as a plant-based flow agent. It helps keep the formula consistent and natural without relying on the kind of heavily processed chemical fillers we want to avoid.
Delayed-Release
Capsules – Delivery On Target
Stomach acid is tough, and for live cultures, the journey matters. Many standard capsules can break down quickly in the stomach, exposing them to acid, which isn’t ideal when you’re trying to deliver live bacteria intact all the way through to the gut.
That’s why we chose to use delayed-release capsule technology. The goal is simple: help protect the live cultures as they pass through the stomach and release later in the digestive journey. This supports targeted delivery and helps preserve their effectiveness, giving the live cultures the best chance of making it through in good condition so they can do their best work.
We built this into our products from the beginning because we didn’t want to finish perfecting strain selection and formulation only to compromise at the delivery stage. For us, it’s part of what “no cutting corners” really means: it’s not just what’s in the capsule that matters, how it gets to your gut matters too.
Transparent
Science You Can Trust
We didn’t choose our strains because we like the way they sound. We chose them because they’re among the most researched live bacteria strains in the world.
LGG is one of the most widely studied strains in human research, with a long history of clinical investigation across a range of settings and in the context of a range of conditions. BB-12 is similarly well documented, with decades of published human research and a strong evidence footprint in gut-related and seasonal wellbeing contexts. Both of these bacteria have hundreds of human clinical trials behind them, and we’re proud to have them as our flagship microbes.
You’ll see us use phrases like “researched in the context of” and “studied in relation to” for a reason. We take UK compliance seriously, and we avoid medical promises or disease-based language. We believe in clear science that is transparent, and clear results you can understand. If a strain has been explored in high-quality human trials, including randomised, double-blind, placebo-controlled studies, we think it’s reasonable to explain what they found clearly, and to share the sources so you can see it for yourself and learn about these incredible microbes and what the research shows.
We only believe in evidence of the highest quality. We prioritise research in humans, not animals, repeated findings across multiple teams and countries, and study designs that reduce bias for a fair test and fair results. The goal isn’t hype; the goal is confidence built on clarity and science of the highest standard that you can trust.
A Formula For
All
At BetterGuts we believe supplements should be accessible for everyone, no matter their diet, culture, or beliefs. That’s why Better Guts is designed to fit a wide range of lifestyles and dietary preferences.
Our products are vegan- and vegetarian-friendly, gluten-free, non-GMO, and gelatin-free. We’ve kept our formulas clean and removed unwanted extras and additives, so what you’re taking is simple and purposeful, and every ingredient has a reason to be there. No flavourings, no colourings, no chemical fillers—just clear, purpose-driven ingredients, each with a job to do.
We’re proud that our products are manufactured right here in the UK, using live cultures grown and produced in the EU. It’s part of our commitment to quality, consistency, and doing things the right way from start to finish.
Our Core Ethos
Everything we do comes back to our core ethos: clean, science-backed, purpose-driven supplements with clarity and precision.
One highly researched strain per product. High-strength CFU. Plant-based prebiotic fibres. Delayed-release delivery. Transparent research you can understand and explore. That’s what Better Guts is built on, and it’s why our range stays intentionally small and focused, so we can ensure we deliver the best.
