About Glutagen

Our Company

Providing Innovations in Gluten Science

Glutagen is a biopharmaceutical company based in Melbourne, Australia, focused on providing clinically-relevant and scientific evidence-based complementary medicines to support the health and wellbeing of individuals with gluten-related issues. Glutagen’s holistic approach to personalised health involves the provision of the highest quality products, including its innovative enzyme supplement, GluteGuard®.

Our Philosophy

Enhancing lives through innovation

At Glutagen, our mission is to help everyone who experiences gluten digestion issues. We understand the significant impact gluten can have on quality of life and how challenging it can be to maintain a gluten-free diet. This underpins our commitment to providing the highest quality complementary medicines for supporting a gluten-free diet in those with diagnosed gluten sensitivities.

For decades, our team has contributed to the global scientific effort to better understand gluten digestion. In 2001, the year Glutagen was established, our scientists discovered that caricain, a natural enzyme found in the oleoresin of papaya fruit (Carica papaya), can break down gluten peptides into smaller, harmless fragments.

Glutagen has transformed this scientific discovery into GluteGuard, a unique consumer product supported by clinical studies to complement the gluten-free diet. GluteGuard uses the natural digestive power of caricain to help minimise the incidence of symptoms caused by gluten contamination.

As a fully Australian-owned and operated company, we are proud to support health and wellbeing through the provision of dietary supplements developed and manufactured in Australia to the highest global quality standards: Good Manufacturing Practice (GMP).

Glutagen’s ongoing investment in research and product development will help ensure today’s scientific and clinical advances can benefit gluten-sensitive and gluten-intolerant individuals in the future.

He has authored over 100 published scientific papers and presentations, and held appointments at Birmingham University (UK), University of Zurich (Switzerland), Karolinska Institute (Sweden) and Technical University (Germany). Prof. Cornell conducted founding work on the enzyme deficiency hypothesis in coeliac disease and holds several patents.

Dr Ted Stelmasiak


With over 25 years of experience in the biopharmaceutical industry, Dr Stelmasiak (DVM, PhD, MACVSc) founded Glutagen to provide solutions for people suffering symptoms due to gluten intolerance. Having held appointments with the Polish Academy of Sciences (Warsaw), the Imperial Cancer Research Fund (London), The University of Hawaii, Honolulu (USA), the University of Melbourne and the Victorian Institute of Animal Science (AU), Dr Stelmasiak has published over 60 scientific papers, filed several patents and developed treatments for bacterial and viral gastroenteritis.

Dr James Rothel


Jim Rothel is an executive with over 30 years experience in biological research and development, mainly in the area of diagnostics. He has a PhD from Melbourne University, and was a member of the CSIRO team that invented a novel, interferon- γ based, method for measuring cellular immune responses in vitro. They developed a diagnostic test for bovine tuberculosis that was awarded the CSIRO Medal for Research Achievement and a human diagnostic, Quantiferon, which changed the way the world diagnoses latent tuberculosis. For his contributions he received the Clunies Ross Award for application of technology in 2013.
