Designed by scientists. Trusted by experts.
Symprove is the result of 40 years of research, including 15 independent studies at University College London and Kings College London, showing the effectiveness of our patented design.
The science of survival
Live and active bacteria supplements only work if their bacteria can survive stomach acid and reach your gut alive.
Our patented water-based solution is designed precisely for that.
Live, active bacteria
Suspended in a unique liquid solution, not freeze-dried.
Precision fermentation
Our 21 hour process uses germinated barley extract (gluten free) to train bacteria to survive your stomach acid
Proven delivery
100% unique bacterial strains, guaranteed to reach your gut
40 years of research
Symprove has been tested by research teams at UCL, King’s College London, and ProDigest.
These studies confirm that Symprove's live and active bacteria survive stomach acid and arrive active and ready to thrive in your gut.
“Bacteria are living and like to live in water, so a water-based product is going to be the most effective at delivering live bacteria to the gut.”
Professor Simon Gaisford, UCL
