Is Symprove gluten-free?

Symprove is gluten-free according to the Codex standard of <20ppm. Whilst barley, which contains a form of gluten, is used to make the liquid in which we grow the Symprove bacteria, the production process is carefully controlled to limit the release of gluten from the barley, and the barley grain is not included in the finished product. Compliance with the Codex standard for gluten free is confirmed with regular testing of batches of our finished Symprove products.
