The science behind Symprove

Symprove supports serious research. Committed to developing the understanding of the function and role of the microbiome, we also use a scientific approach to developing the most effective bacteria based product.

Our research

Founded in 2002, Symprove Ltd has been committed to extensive research and testing from the start. We want you to live a healthier, happier life, and because of this we’ve supported multiple research programs, both into the microbiome and Symprove itself. 

Several scientific studies have been carried out on Symprove and studies published so far include: 

  • Effective delivery system – survival of the Symprove bacteria through the Gastrointestinal tract
  • Gut function and how this is impacted by use of multistrain live bacteria products

Putting Symprove to the test

In an independent study at University College London* Symprove was successful in its ability to survive, thrive and colonise the gut.

University College London carried out an independent study on products containing bacteria. The study subjected each product to three tests. These assessed if the bacteria arrived in a live state, survived stomach acid transit and thrived in the target area of the gut. Symprove was able to pass all three tests.

How Symprove is tested?

Symprove undergoes rigorous testing before being dispatched to our customers. Because we’re so committed to making sure Symprove meets our strict manufacturing guidelines, each
batch is tested by an independent laboratory. The independent testing is carried out by a Good Manufacturing Practices (GMP) laboratory.

Gluten-free testing

Although we use barley extract to create Symprove, during the production process any gluten in the barley is removed. Samples are checked to ensure Symprove remains under the 20 parts per million limits for a gluten-free product. All this means we can be confident your bottle of Symprove is rigorously tested and of the highest quality.

Committed to sustainability

Concern for the environment is integral to Symprove and we take our responsibility to sustainability very seriously. Here are some of the ways we are committed to the ongoing process of reducing our impact on the planet

Harnessing the power of the sun

As a far less environmentally-damaging option, Symprove have invested in solar panels for our entire site, and we aim to produce 80% of our energy this way. This will enable us to move towards a carbon neutral approach to energy usage. So the energy from the sun that helps to grow our Symprove barley grain also powers our computers to take your orders and lights our offices.

Working wonders with water

Offices can be vast consumers of water, with consumption in the UK averaging at the equivalent of three office water coolers per employee per day. Well over half of this is used for flushing toilets. For over a decade here at Symprove we have been using ‘grey’ water (rainwater) to flush all the toilets in our office. It’s great to think that at Symprove water that would otherwise literally go down the drain is being reused and recycled.

Our packaging

We are also committed to reducing our impact on the environment through our packaging. We have recently upgraded our bottles to PET plastic (the world’s most recycled plastic) to ensure that they are more widely recycled; our outer packaging is also fully recyclable.
