GC Rieber Oil's collaboration with Haukeland University Hospital on omega-3 clinical study

Kristiansund 26th June 2020

GC Rieber Oils enters into collaboration with Haukeland University Hospital on a clinical study. The study, which is scheduled to start in 2020, will be led by Senior Consultants from the Department of Rheumatology and clinical dietitians at Haukeland University Hospital. 

In the study named “EROM: Nutritional Intervention in Rheumatic Disease - Effect of Marine Omega-3 Fatty Acids and Individual Dietary Guidance", the Haukeland team will follow patients with inflammatory arthritis for one year. It will be investigated whether diet optimization and supplementation of omega-3s can reduce disease activity.

Several studies indicate that omega-3 has a positive effect on disease activity in inflammatory rheumatic disease, including arthritis. It is, however, a need for studies that look at the effects of proper diet and omega-3 intake over a longer period of time. Many researchers point to the importance of using a high enough dose of omega-3 and note that some studies may have failed to document efficacy due to insufficient dosage. In the study at Haukeland, one of GC Rieber’s new VivoMega omega-3 high concentrate will be used in a clinical study that also examines patients' nutritional status and intake of nutrients.

The study will have a comprehensive focus on nutrition and diet in patients with individual guidance and close follow-up by the clinical dietitian during the project period. Such an approach could add new insights regarding rheumatic disorders, according to the experts at Haukeland University Hospital. "As a manufacturer of health-giving omega-3 products, we at GC Rieber Oils are committed to contributing to research that looks at the relationship between omega-3 and health," says CEO Jan Roger Bjerkestrand.

Much has been done in the treatment of rheumatic diseases over the last 20 years, but several of the medicines used are associated with adverse side effects, e.g. increased risk of infections, says Senior Consultant, dr.med. Anne-Kristine Halse who will be the project manager for the study.

If we find that a higher intake of omega-3 through diet and supplementation can reduce the disease activity and thereby lower the use of other drug therapies, it could lead to increased quality of life for patients in this group. This will be a significant step in the right direction,” says CTO at GC Rieber Oils dr.scient. Bente J. Foss.

The study is partly founded by the GC Rieber Foundation.
