Featured Questions

Why is Zenflore special?

The 1714-Serenitas™ culture in Zenflore is a unique bacterial culture that has been clinically studied in people with everyday stress1. It's been shown to reduce the level of our stress hormone, cortisol and the impact of stress on daily life1.

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 work specifically on the area for which it was developed.

Is the culture Zenflore natural?

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.

What are the ingredients in Zenflore?

Zenflore contains the natural bacterial culture 1714-Serenitas plus specially selected B vitamins:

  • Thiamine (vitamin B1)
  • Riboflavin (vitamin B2)
  • Niacin (vitamin B3)
  • Vitamin B6
  • Folic acid
  • Vitamin B12
  • Biotin
  • Pantothenic acid

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.

How many bacteria are in each capsule of Zenflore?

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.
