We've collected answers to some of our most frequently asked questions.

What are PrecisionBiotics®?

What are PrecisionBiotic cultures?

PrecisionBiotic cultures are unique bacterial cultures that have been specifically researched and rigorously tested by PrecisionBiotics.

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 real people to ensure they have the precise qualities 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.  

How do bacterial cultures in food supplements compare with yoghurts?

Most yoghurts contain bacterial cultures. If bacterial cultures have been added during the manufacturing process, they may not be cultures that have been tested in clinical trials or that are native to the human gut. 

Is it worth taking several bacterial strains together?

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

As scientists, we know that mixing multiple bacterial cultures can mean their individual qualities are affected. Different cultures behave in different ways and may even have competing effects. And cultures of animal origin are not native to the human gut so we do not add them.

It is the specific culture of bacteria and how that culture interacts with your unique gut bacteria that determines whether you will notice a difference.

So our focus is on investing to find the best bacterial culture for each specific gut action. We then put each through a rigorous series of tests, culminating in clinical trials in the UK and Europe. 
We produce a pure formulation, with no added bulk yoghurt or animal cultures, to provide a PrecisionBiotic®product that we can guarantee and that clinicians can recommend. 

We also guarantee that the number of bacteria is the optimal amount for each PrecisionBiotic and the human gut.
