What exactly is Symprove?
Symprove is a unique, water-based probiotic with four strains of live and active bacteria. Symprove is proven to reach the gut alive and support the microbiome.1,2
Did you know that Symprove is rated the most evidence-based probiotic by UK dietitians?3 Discover the data that supports this with the results of our double-blind, randomised controlled trials conducted at King's College Hospital.
Proven by independent experts
In an independent study by UCL School of Pharmacy, Symprove’s bacteria were shown to arrive, survive and thrive in the gut.1
The study investigated a range of probiotics in an in vitro model simulating human gut conditions.
Hear from Principal Investigator, Professor Simon Gaisford, as he explains why Symprove performed strongest in the study.
Recommended by clinical and scientific experts
In order to be effective, probiotics need to 'arrive, survive and thrive’
Symprove is different from other probiotics because it is water-based, which means it limits exposure to gastric juices and digestives enzymes
We are proud to partner with Symprove to raise awareness of a product that has already been helpful to so many people
In a world where there are many claims about gut health (with good evidence!), I'm so enthused by Symprove's research, and what we are seeing from the results.
92% of people report a difference with Symprove over 3 months and we offer healthcare professionals a free trial to see for themselves
Symprove bacteria
Symprove is considered to have the highest quality strains of any probiotic by gastroenterologists.3 Symprove contains four live strains of bacteria:†
Lactobacillus acidophilus
NCIMB 30175
Lactiplantibacillus plantarum
NCIMB 30173
Lacticaseibacillus rhamnosus
NCIMB 30174
Enterococcus faecium
NCIMB 30176
Lactiplantibacillus species
- Various types of these bacteria are found in the human gastrointestinal tract
- Rhamnosus, acidophilus and plantarum all have a history of being used in food4
- The European Food Safety Authority has added these three species to the Qualified Presumption of Safety list5
Enterococcus faecium
- These bacteria are commonly found in human microbiomes and have a history of being used in food6
- The strain used in Symprove is fully characterised and has been subject to whole genome sequencing by the NCIMB, to confirm identity and provide safety data, which differentiate it from other strains7
Symprove safety
- Dietitians' most trusted probiotic3*
- >40,000 people take Symprove every month3
- Randomised controlled trials investigating Symprove in those with pre-existing medical conditions, have been approved by ethics committees and no serious adverse events have been recorded in any trial8-10
- No serious adverse events have been recorded since commercial sales began in 20107

†Symprove contains four live strains of bacteria: Lacticaseibacillus rhamnosus NCIMB 30174, Enterococcus faecium NCIMB 30176, Lactobacillus acidophilus NCIMB 30175, Lactiplantibacillus plantarum NCIMB 30173. The bacteria in Symprove have all been independently characterised by the NCIMB (The National Collection of Industrial and Marine Bacteria) using the latest DNA sequencing and mass spectrometry techniques. These methods have enabled characterisation of the genera, species and strains.
Symprove delivers 10 billion CFUs (colony-forming units) per 70ml cup, consistent with amount used in human clinical research trials.
