The most powerful duo in live bacteria
High Strength.
Our single-strain formulae contain 12 billion live bacteria, using clinically tested, evidence backed strains. Manufactured in the UK using live cultures grown and produced in the EU.
Backed By Science.
Our strains of bacteria are supported by hundreds of gold-standard clinical trials. We rely on proven research, not trends, to shape our formulas, ensuring each blend delivers reliable, evidence led support for your gut.
Clean Formula
Every product is vegan, gluten-free, non-GMO, and gelatin-free. We also avoid common fillers, using bamboo-derived silica instead: a plant-based flow agent that helps keep our formula clean.
Targeted Release.
Housed in a delayed-release capsule this smart delivery helps protect from stomach acid, and ensures more of the live cultures reach your gut alive, right where they’re needed most for optimal impact.

Your questions, answered
Explore our most frequently asked questions or use our chat to ask our founder Matthew directly.
I took probiotics before and they didn’t work! What makes these any different?
It all comes down to the bacteria we use! Did you know that a lot of cheap probiotics on the market today use bacteria that have never been proven to have benefits in humans? Or even tested in humans? We decided there was a better way. The two microbes we work with, LGG and BB12, are the two most clinically proven bacteria in the world, each with hundreds of human clinical trials to demonstrate what they can do. So, with Better Guts you know you’re getting bacteria backed by real clinical science, not just hype and marketing!
Why is ‘single strain’ better than an everyday blend of different bacteria?
Everyday blends are sometimes good, and there are some on the market that use very good bacteria, BUT, to make the product affordable a lot of the time those bacteria have to be in a weaker concentration. If it says 25BN CFU on the label, but there are 5 different bacteria, there’s not that much of each one in there! The problem with this is that while the bacteria will work to some extent, they’re not in a strong enough concentration to have a really solid impact, and can get ‘lost in the noise’ of your gut microbiome. Using single strains in each product allows us to put these microbes in a high concentration of 12BN CFU per serving, making sure you get enough of each clinically proven microbe to really get the effects you want, and to build up a solid population of the beneficial bacteria!
What do probiotics actually do?
Our gut is filled with trillions of bacteria. In fact, by some estimates more than
50% of our body is bacteria! These little creatures exist alongside each other,
and they can have an impact on every aspect of our health. They can affect
brain function, organ function, mental health, digestive health, you name it,
they have an impact. However, some of the bacteria that can take root are
pathogenic, and can cause health problems in humans, especially if they’re in
large populations. So, with probiotics we send in live bacteria from the
beneficial families. This way we can keep the population of good bacteria
strong! They can then help to outcompete the bad bacteria and keep their
numbers low, helping to prevent them from having an impact on your health.
What can these products do for me?
When it comes to everyday probiotic gut support, this is a team it’s hard to beat! They’re both very good for people who experience digestive issues such as bloating, cramping or diarrhoea, as well as both being solid choices to take
alongside antibiotics to help rebuild the microbiome. They also work really
well together to help keep the bad bacteria supressed, maintaining a strong population of the good guys to keep your gut resilient! And of course, as just a solid every day probiotic, they work as an unbeatable team with real clinical evidence to keep you consistent and your gut happy!
How long do I have to take them for?
With probiotics consistency is key! You should start to notice effects after a
couple of weeks, but for the best results you should take them consistently for
at least a few months. This allows the bacteria to build up a strong
population. Once they get to a good number they start to really have an impact on the population of bad bacteria, and that’s when you start to get the best results! Once you have that population built up, sticking with it in the long run will help to keep their numbers high, your gut consistent, and your routine solid and predictable.
