What exactly is Symprove?

Symprove is a unique, water-based probiotic containing four strains of live, metabolically active bacteria. Supported by independent research, Symprove is proven to reach the gut alive, supporting regulation of the gut microbiome. 1,2

Did you know that Symprove is rated the most evidence-based probiotic by UK dietitians?3* That's because we're supported by 20+ clinical and scientific research papers in the final product formulation, including randomised controlled trials from leading institutions.

Symprove bacteria

Symprove contains four patented bacteria strains, rated as the highest quality strains of any probiotic by UK gastroenterologists.

In-house microbiologists use a precision fermentation process to prepare the bacteria to arrive in the colon in a live and metabolically active state.

Lactobacillus acidophilus

NCIMB 30175

Lactiplantibacillus plantarum

NCIMB 30173

Lacticaseibacillus rhamnosus 

NCIMB 30174

Enterococcus lactis

NCIMB 30176

Symprove bacterial species

Lactobacillaceae

  • Various types of these bacteria are found in the human gastrointestinal tract
  • L. rhamnosus, L. acidophilus and L. 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 lactis

  • 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 doesn't contain any added sodium as an active ingredient. However, a small amount of sodium is present because of a few of our processes and ingredients. As only 0.07g is present per 70ml shot, Symprove is generally suitable for those required to follow a low-sodium diet. For added reassurance, please consult with your GP or healthcare professional should you have any dietary concerns.

†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 at point of manufacture) per 70ml cup, consistent with amount used in human clinical research trials.
