PrecisionBiotic cultures are unique bacterial cultures that have been specifically researched and rigorously tested by PrecisionBiotics.
All 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.
We have created special formulations which are stable, ensuring that none of our products need refrigeration.
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 strain 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.
The 1714-Serenitas® culture in Zenflore is a unique bacterial culture that has been clinically studied1.
Zenflore is the only product that contains the 1714-Serenitas® culture.
This unique culture in Zenflore is a bacterial culture that occurs naturally in the human gut. It is part the Bifidobacteria family, one of the first kinds of bacteria passed by mother to baby at birth2.
It is a PrecisionBiotic which works specifically on the area for which it was developed.
Yes. Zenflore contains the 1714-Serenitas® culture, a bacterial culture that occurs naturally in the human gut.
It's part of the Bifidobacteria family of bacteria that are given by mothers to their babies at birth2.
To ensure this natural culture reaches your gut with its properties intact, we have created a special formulation which is stable at room temperature so it does not need refrigeration.
Zenflore contains the natural bacterial culture 1714-Serenitas® plus specially selected B vitamins:
There are also some excipients to help with formulation, all held in a clear capsule.
There are no known allergens in Zenflore. All raw materials used for Zenflore do not contain any allergen listed in the Directive 2007/68/EC and its amendments. The facilities we use to manufacture also ensure that during the production process, raw materials are not exposed to cross contamination from allergens.
Please see the outer pack for a full ingredient list.
A single Zenflore capsule contains around 1 billion bacteria, or 1x109colony forming units (CFUs), at the time of manufacture.
The quantity of bacteria in each capsule has been chosen for optimal action. It has been rigorously tested by scientific teams, culminating in testing in clinical trials.
Zenflore contains a single culture, the specially selected Bifidobacterium longum 1714-Serenitas® culture. 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. Cultures of animal origin are not native to the human gut so we do not add them.
The gut produces more than 90% of the serotonin found in your body 7, a neurotransmitter that can affect your mood and feelings of happiness and pleasure. Research has shown that gut bacteria can impact serotonin production in the gut8 and research indicates that a gut with a healthy microbiota is a strong predictor of health and wellbeing9.
Zenflore, with the unique 1714-Serentitas® culture and specially selected B vitamins, provides support for your mind and body during busy and demanding times, reduces fatigue and supports mental performance.*
The special 1714-Serenitas® culture in Zenflore was discovered and developed by PrecisionBiotics and has been clinically studied1 in partnership with scientists and clinicians from one of the world’s leading centres of research on the microbiome.
The special 1714-Serenitas® culture in Zenflore acts by becoming part of the gut microbiota that are involved in the gut-brain axis, the 2-way communication between brain and gut via the vagus nerve4.
Take one capsule every day. Zenflore can be taken with or without food, at any time of the day.
Note: Fruit juices are generally acidic and acid can damage the 1714-Serenitas® culture. We recommend taking Zenflore with water or milk or less acidic drinks e.g. soya, almond or rice milks.
However, Zenflore can be taken as part of a meal that has fruit juice, as the food will help protect the culture in Zenflore.
If there is an issue with swallowing the capsule, the capsule can be opened and sprinkled over food or mixed with fluids.
Do not exceed the stated dosage. Food supplements should not be used as substitutes for a varied diet and a healthy lifestyle. Keep out of the reach of children.
Zenflore acts immediately and begins to prime your gut where it is needed. During the first 2 weeks it will help reset your system. It is important to take Zenflore every day. To see the full effects of Zenflore can take approximately 4 weeks, depending on the individual gut.
As Zenflore begins to gently prime the gut, some people may experience mild and temporary changes in their gut during these first weeks.
In rare cases it may take Zenflore longer than 4 weeks to prime an individual gut, possibly up to 8 weeks. If you have any questions about Zenflore, please contact our Careline on

There are no known interactions of Zenflore® with medicines. If you are prescribed antibiotics, it is best to take Zenflore® at a different time of day from the antibiotics because the bacteria in Zenflore® can be inactivated by antibiotics. If the medication you are prescribed suppresses the immune system we recommend you take extra care when considering taking products containing bacterial cultures.
If you have a medical condition or have questions about whether Zenflore® is suitable for you, please consult your doctor. They will be best placed to advise in the context of your full medical history.
As happens with most bacterial cultures, a dose of antibiotics could inactivate the bacterial culture in Zenflore.
If you have to take a course of antibiotics, we advise that you take the dose of the antibiotic at a different time to your daily dose of Zenflore.
