Our commitment to research


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

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

  • 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
  • Emerging research – The impact of Symprove on other components of the microflora and implications for the maintenance of human health

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 three times by an independent laboratory.
The independent testing is carried out by a Good Manufacturing Practices (GMP) laboratory.

Gluten free testing


We use barley extract to create Symprove, during the production process any gluten in the barley is removed. Samples are sent to be 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.
