Backed by over 15 years of independent scientific research at leading UK universities. We’ve worked with scientists to prove Symprove’s unique live and active bacteria:
Rooted in science
We take science seriously, in our labs and beyond. It's why we've collaborated with some of the UK's leading scientists in large independent trials. The results? Symprove really works.
Come and see…
Our research
ALIVE
Symprove's bacteria are alive when they enter the body
SURVIVE
They can survive as they pass through the stomach
THRIVE
They can reach the lower gut and thrive there!
Say hello to our ingredients
Working in harmony with your body (and each other)
Live bacteria
Symprove contains four species that occur naturally in your gut. We selected Lactobacillus for its resistance to acid, and all of them for the way they work in synergy and encourage each other to grow.
Germinated barley extract
This clever grain works as a catalyst for fermentation. It helps to speed up the growth of the live bacteria, and keep the numbers steady for Symprove's shelf-life. (We remove all gluten from the barley extract in our production process).
Water
Friendly bacteria love living in water! So water, coupled with the way you take Symprove on an empty stomach, helps limit our bacteria's exposure to digestive juices that would otherwise kill them.
Symprove fits most restricted diets
Symprove is made from 100% natural active ingredients
Vegan
There are zero animal extracts or bi-products in Symprove
Gluten free
We remove all gluten from the barley extract in our production process
No artificial colours
100% natural colour ingredients
From the lab with love
We make Symprove in a controlled environment. We add the bacteria to a water-based solution with a gluten free liquid barley extract. Over a 21-hour period, fermentation occurs, they multiply like mad and train themselves to tolerate low pH levels in order to survive the stomach acid.
Once there's enough bacteria, we halt the process, test our samples and then get bottling.
Billions of good bugs in every bottle
Ready for a fun fact? If you lined up all the bacteria in a shot of Symprove nose to tail, they'd stretch for a whopping 30 kilometres! That's because every shot contains over 10 billion colony-forming-units of good bacteria.

Getting the thumbs up from an expert
Want to hear directly from a scientist? In this handy video, Professor Simon Gaisford explains what makes Symprove different and why caring for your gut matters.
Testing makes perfect
We want to make sure that our quality and purity is spot on. That’s why our production process is patented and overseen by expert fermentation scientists. And our internal quality management systems are run to internationally-approved standards.
Love your gut – and save!
Balancing your microbiome is a marathon not a sprint. That's why it's good to try Symprove for at least 12 weeks, when 94% of people feel the difference.

Caring for the planet
We know our planet is in crisis and take our responsibility to protect it seriously. Here's what we've done to reduce our impact so far.
We've covered Symprove HQ with solar panels
The aim is to produce 80% of our energy this way.
Our loos are flushed with rainwater
So water that would literally go down the drain is being recycled.
We've upgraded our packaging
All our bottles are made from PET plastic (the world's most recycled plastic).
