Oslo, July, 27, 2022: A new study conducted by CSIRO, Australia’s national science agency, across three clinical trial sites in Australia, and sponsored by Swisse’s H&H Research, investigated the effects of krill oil on adults suffering from mild to moderate knee osteoarthritis (OA).
The six-month rigorously designed clinical trial concluded that Swisse High Strength Deep Sea Krill Oil (Superba™ BOOST krill oil phospholipids) was safe to consume and resulted in improvements in knee pain, stiffness and physical function in adults with mild to moderate knee OA.
Swisse’s Superba BOOSTTM krill oil supplier is Aker BioMarine.
“We are very happy with the results from this well-executed trial,” said Line Johnsen, Vice President of Science and Regulatory Affairs at Aker BioMarine.

“Not only did Superba BOOST™ krill oil phospholipids significantly reduce knee pain, but it also improved stiffness and the physical function of the knee. An additional interesting finding in the study was that the participants with the greatest level of inflammation at the start of the study were the ones that had the biggest pain improvement. It is great to have an alternative treatment, without side effects, for people suffering from osteoarthritis of the knee.”
Nick Mann, CEO for Swisse’s parent company H&H Group for Australia, New Zealand and Asia said: “We are very pleased to have brought together high-quality partners from supply chain, research and industry to build a research collaboration that is not only scientifically meaningful, but also commercially valuable for all involved.”
Study details and results
The 235 healthy men and women who participated in the study were between 40 to 65 years of age who habitually consumed low amounts of long-chain omega-3 fatty acids in their diets and no fish oil supplements and had all received a clinical diagnosis of osteoarthritis of the knee. The study ran for six months between 2018 and 2019, and participants were randomly divided into two groups: one placebo- group and one test group receiving four grams of krill oil per day providing 880 mg of long-chain omega-3 fatty acids and 450 mcg of astaxanthin. Participants were assessed at baseline, three and six months.
The study showed that knee pain was improved in the krill oil group versus the placebo group over the six-month period. Additionally, knee stiffness and physical function had greater improvements in the krill oil group compared to placebo. The knee outcomes were assessed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) numeric scale, the gold standard method for evaluating hip and knee osteoarthritis.
Furthermore, the level of Omega-3 (Index level) increased in people in the krill oil group from 6.0% at baseline to 8.9% at three months and 9.0% at six months. CSIRO principal research scientist and study lead, Dr Welma Stonehouse said rigorous science has an important role to play in validating the effectiveness of complementary medicines.
“Four years in the making, this clinical trial represents the largest, longest, and highest dose study to date investigating the effects of krill oil on osteoarthritis of the knee,” said Dr Stonehouse, CSIRO Principal Research Scientist.
Knee pain is a common sub-type of osteoarthritis, with studies showing that the global prevalence of knee OA was 30% in individuals aged 40 and over . Non-surgical relief of this pain typically involves use of non-steroidal anti-inflammatory drugs (NSAIDs). Due to the adverse effects of these medications, researchers are in pursuit of effective, alternative treatments. Previous studies and clinical trials have suggested that omega-3 polyunsaturated fatty acids derived from marine sources might be one such alternative to relieve joint pain.
This study published in the American Journal of Clinical Nutrition is titled “Krill oil improved osteoarthritic knee pain in adults with mild to moderate knee osteoarthritis: A 6-month multicenter, randomized double-blind, placebo-controlled trial” and was authored by Welma Stonehouse, Bianca Benassi-Evans, Jana Bednarz, Andrew Vincent, Stephen Hall, and Catherine L. Hill.
