Our Science

Over 17 years ago, our scientists began researching thousands of live bacterial cultures (also known as probiotics) together with experts from one of the world's leading centres of microbiome research, the APC Microbiome Institute. Our company, PrecisionBiotics, is part of the Alimentary Health Group who are a key partner of this innovative research institute.  

Since then, they've discovered hundreds of different bacterial cultures and put each one through rigorous scientific tests. Amongst these hundreds are a handful of special bacteria that stand out because of the precise and significant impact they make to human gut health.

When these unique cultures pass all our tests, which include clinical trials in the UK and Europe, the PrecisionBiotics® team are proud to produce them in a high quality and convenient form for consumers and clinicians.


Natural Products 

Our products contain bacteria that occur naturally in the human gut

The human gut is a sensitive place and all of our products contain bacteria that occur naturally in the human gut and are at home there.  

We spend many years observing and testing them in people, to ensure they deliver the precise effects needed and that they meet our rigorous safety standards.

To ensure they reach your gut in peak condition we have created special formulations and we have confirmed their activity in the gut using the highest standards of scientific testing and human clinical trials. These stable formulations also ensure that none of our products need refrigeration.  

Precise Bacteria, Exact Quantity

We're often asked why our products contain only 1 or 2 precise cultures, instead of a mix of 5 or even 10 types of bacteria

As scientists, we know that mixing multiple bacterial cultures does not guarantee that each will retain its properties or that different cultures will even complement each other. Different cultures behave in different ways and may even have competing effects. 

So our focus is on discovering the best bacterial culture for each specific gut action. We put each through a rigorous series of tests, culminating in clinical trials in the UK and Europe. 

We then produce a pure formulation, with no added bulk yoghurt cultures nor cultures of animal origin as they are not native to the human gut. We also guarantee that the number of bacteria is the optimal amount for each PrecisionBiotics® product and the human gut. The selected bacterial culture in each of our products is also stable at room temperature and does not need refrigeration.

We provide a PrecisionBiotics® product that we can guarantee and that clinicians can recommend.

Our discovery partners are world-leading experts in the human microbiome

Our discovery partners are world-leading experts in the human microbiome. They include the APC Microbiome Institute in Ireland and our work as part of EU projects such as MyNewGut and NeuroGut.

Together with our partners, our research has been published in leading scientific journals. See highlights of our Research publications here.

For our scientists, one of the key motivators is the feedback we get from the people who trust and use our products every day.  Regardez ce que nos clients disent de nous.

The Importance of Gut Health

The gut microbiome has been described as the forgotten organ.

Scientists are just beginning to understand the complex relationships we have with the bacterial cultures in our gut (our microbiome) and the relationships they have with each other.

Many factors can disturb this delicate balance, including antibiotics, stress and inadequate nutrition. Digestive conditions are also more common than ever, including food intolerances, constipation, bloating and abdominal pain. 

In the last decade, research has also shown the impact that gut bacteria can have on our stress levels and mood, also known as the gut-brain axis. Several of PrecisionBiotics® research partners are now involved in leading edge research in this area.
