Meet Our Founder

Matthew Campbell-McBride founded Better Guts with 1 mission.

Having been born and raised in the world of holistic healthcare and nutrition, I developed a passion for the microbiome and gut health that I just couldn't shake. The way our gut microbes affect our health fascinated me. The more I spoke to people about probiotics, the more I saw a trend in the space, too many supplements promising the world, but delivering very little results with unproven ingredients, cashing in on the trend. So I started Better Guts with one goal: to make probiotics that actually work. Commitment to evidence-led, science-backed ingredients, has shaped my approach since the very start. If it's not backed by science, it doesn't go in. Simple as that. With no added chemicals, for a clean formula, backed by clear science, that does exactly what it says it will. Welcome to Better Guts.

The Science Comes First

Every Better Guts product is built around one of the world's most researched probiotic strains: LGG or BB-12.

We chose them because decades of independent human research, not marketing trends, support their use in everyday gut health. With literally hundreds of studies behind each microbe we work with, the effects are clear, simple, and proven. No guesswork, no marketing language, just live cultures chosen for their evidence and results.

Delivered With Precision

Did you know that many probiotics are killed by stomach acid, never reaching your gut alive?

The stomach is acidic, and it kills bacteria, including your probioitcs. That's why at Better Guts we use precision delivery with delayed release capsules. These protect our microbes from the stomach acid for delivery where they're needed most, your gut.

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.
