PrecisionBiotic cultures are unique bacterial cultures that have been specifically researched and rigorously tested by scientists at PrecisionBiotics Ltd.
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. Their stable formulations also ensure that none of our products need refrigeration.
We're sometimes asked why our products contain only one or two types of bacteria, instead of a mix of five or even ten 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 or plant origin may not be 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 culture 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 product and how it works in the human gut.
Many yoghurts contain live bacterial cultures but these are usually chosen to make good yoghurt, not for their activity in the human gut. 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.
Why is Alflorex® different?
Alflorex is the only product in the UK that contains the unique 35624 live bacterial culture.
This culture has been clinically tested by leading scientists and gastroenterologists. The results of these trials have been published in a wide range of respected scientific journals.
The live 35624 culture in Alflorex is a type of bacteria that occurs naturally in the human gut. It's part the Bifidobacterium group, one of the first kinds of bacteria passed by mothers to their babies at birth.
Is the bacterial culture in Alflorex natural?
Yes. Alflorex contains the natural Bifidobacterium infantis 35624® culture, that is a type of bacteria that occurs naturally in the human gut. It's part of the Bifidobacterium family of bacteria that are given by mother to baby at birth.
To ensure this natural live culture reaches your gut with its properties intact, we have developed a special formulation and confirmed its activity in the gut in clinical trials, using the highest standards of scientific testing and human clinical trials.
This stable formulation also means that Alflorex does not need refrigeration.
Will Alflorex reach my bowel in peak condition?
Yes. The 35624® culture in Alflorex has been shown in 2 clinical trials, reported in respected scientific publications, to remain active right through the digestive system and to reach the bowel with its properties intact.
It's now the No. 1 recommended bacterial culture by doctors and gastroenterologists in the US.
How many bacteria does each capsule of Alflorex contain?
A single Alflorex capsule contains around 1 billion live bacteria, or 1x109 colony forming units (CFUs), at the time of manufacture.
The quantity of bacteria provided in each capsule has been chosen for optimal balance in the gut.
The dose in the capsule remains effective throughout its shelf life.
Alflorex acts immediately and begins to prime your gut where it is needed.
This activity takes approximately 4 weeks. It is important to take Alflorex every day.
