As people get older, they often experience knee pain, which may progress to degenerative joint changes leading to osteoarthritis (OA). OA is a common form of joint disease which can be painful and affect movement and other activities. It is associated with damage to the structure of the joint and related inflammation. There is no cure and treatment of OA usually focuses on management of pain or surgery. Although OA is affected by genes and environmental factors, emerging research suggests diet and lifestyle may also be important.

Collagen supplements are becoming increasingly popular for a range of reasons. They are often marketed as anti-ageing products to enhance skin appearance. There is also some evidence that collagen may affect symptoms of OA or metabolic conditions linked to inflammation, such as metabolic syndrome, but many studies have had inconclusive results. The aim of this study is to investigate the effects of a novel collagen protein (SuprosolTM), extracted from cow hide, on age-related knee pain, skin appearance and inflammatory markers and compare it to milk protein or placebo. Changes in markers of metabolic syndrome will also be assessed because there is an association between these and inflammatory conditions such as OA.

The findings of this study may be important in understanding the causes and identifying new approaches for reducing knee pain and improving OA, a condition which affects over 1 in 10 adults in New Zealand. The results of the study will help to clarify whether collagen supplements are a useful part of the treatment of knee pain.
