Greenshell™ for Osteoarthritis
Symptomatic osteoarthritis is the leading cause of disability in older adults. Progress and presentation of the disease can vary among individuals. Still, there is a common pathway of joint structure pathogenesis, suggesting a standard treatment in the disease’s early stages. At present, there is no effective therapy for osteoarthritis, meaning the market for a clinically tested Greenshell™ mussel product is both extensive and yet to be exploited.
Building on the Musseling Up 1.0 programme’s key novel findings and under the umbrella of the follow-up Musseling Up 2.0 programme, this proposed randomised, placebo-controlled trial (RCT) will recruit individuals presenting with subclinical osteoarthritis. It will investigate the effects of Greenshell™ mussel dietary supplementation, compared to placebo, over six months. The trial is novel in both its population group and its range of outcome measures, including joint health biomarkers, inflammatory status, measures of functionality, pain, and quality of life. The proposed trial will add evidence specific to a population with subclinical osteoarthritis, healthy and undiagnosed but starting to show signs that they are at risk of the disease.
The impact of this research will be through the addition to- and confirmation of- the portfolio of health claims connecting Greenshell™ mussel effects to both physiological signs of osteoarthritis and joint health, such as cartilage biomarkers and inflammation, and symptoms like pain and functionality. Adding to research already undertaken in the Musseling up 2.0 programme, the impact of all this research combined will be the economic growth for New Zealand aquaculture sector through validated health claims.
High-Value Nutrition is one of the eleven National Science Challenges. The Challenge has a $45.6 million budgeted research investment for 2019-2024.
