We are microbiome experts

We're proud to have collaborted with numerous universities and clinical research organisations around the world to conduct over 30 clinical trials using gold-standard research methods. Formulated in the UK, our live bacteria blends and doses are informed by clinical research and an evidence base we continue to develop.

Why use a live bacteria supplement?

Due to modern life and the way we now live, many of us are exposed to a smaller range of microorganisms from the natural environment. At the same time, aspects of modern life including medications, stress, pollutants, poor diet and lack of sleep may negatively affect the gut microbiome.

We've spent over 30 years researching the wonders of the gut microbiome

Bio-Kult’s live bacteria strains are specially protected using advanced cryoprotective technology. A protective coating is applied before freeze-drying, helping the bacteria survive production and storage while remaining dormant until they reach the right conditions in the digestive tract, where they can become active again.

The science

SCIENCE YOU CAN TRUST. STRAINS DEVELOPED BY US.

01

Scientifically researched strains

Not all probiotics are equal. Bio-Kult uses 14 carefully selected bacteria strains, each with its own unique identity, role, and strain number. 

02

Designed to survive

Gut-friendly bacteria have to make it through the acidic environment of the stomach to reach the gut alive. Our strains are individually fermented and freeze-dried

03

Fully traceable

Every Bio-Kult strain carries a PXN number, lodged at NCIMB (National Collection for Industrial, Marine and Food Bacteria) in Aberdeen.

Our ingredients

With a unique combination of live bacteria with the benefits of vitamins and minerals, our products are designed to give your gut just what it needs. 

But that’s not all. Individually fermented before being freeze-dried, our strains and their unique packaging keep the bacteria active, even at room temperature. With no refrigeration required, this gives you the freedom to feel gut great anywhere, whether you’re on the commute or a cruise.

You know they're beneficial, but how do they get their names?

Well, each has three parts: the genus, the species and the specific strain. Whilst strains from the same genus or species may share similar characteristics, they may not necessarily have the same effects, as each strain has its own unique identity.

PXN® strain numbers are allocated to each of our strains following their genus and species classification. These strain identifiers are used in published scientific research conducted using our products, helping to ensure that the specific strains studied can be clearly identified.

  • 1. The genus (e.g. Lactobacillus or Bifidobacterium)

    The genus is like the manufacturer, such as Volkswagen. It identifies the broader group.

  • 2. The species (e.g. casei or subtilis)

    The species is like the model, such as a Volkswagen Golf. Cars of the same make and model share many characteristics, but may also vary based on their specifications.

  • 3, The specific strain (e.g. LGG or PXN® 37)

    The strain is like the specific version of that model, such as a Volkswagen Golf 1.4 TDI. This car has specific characteristics, just as a specific strain does.

  • 4. The end result

    Put them together and you get the exact car, like a Volkswagen Golf GTI, just as Lactobacillus rhamnosus GG names one specific strain.
