Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention for this study is Krill and Greenshell mussel oil (GSM). Participants will be instructed to take 1 capsule in the morning with food, for a total of 500 mg of krill/GSM oil per day for a total of 8 weeks. Each 500 mg capsule will contain 50 mg of GSM Oil and 450 mg of krill oil.

Once enrolled in the trial, participants will be randomly allocated to either the placebo comparator group or the active intervention group. Height, weight, waist and hip circumferences, blood pressure and questionnaires regarding joint pain, osteoarthritis symptoms, gastrointestinal tolerance and quality of life will be assessed at enrolment. Within the week pre-treatment, participant’s blood will be collected for analysis of pre-treatment inflammatory blood markers.

Prior to starting trial product, participants will complete 1 day of pain recording [(Vas) once morning and once at night] online. Following the completion of the pain recording, the participant will start taking the capsules. Participants will be asked to take the allocated product according to the dose prescribed (500 mg daily). In addition, participants will be asked to complete fortnightly questionnaires regarding their joint pain (Vas and WOMAC). Participants will undertake an additional blood test at week 4 and repeat all baseline measures at the completion of the trial (week 8).

At both time point visits (week 4 and 8) and as part of the assessment, participants will be asked to provide details regarding any lifestyle changes (diet, exercise, medication) in addition to subjective changes in exercise, performance and any adverse effects (including change mood/quality of life).

Participants will be monitored for compliance with the protocol by a combination of telephone and email communications in addition to each scheduled visit.

Summary
Brief summary
Effect of a combined Krill and Greenshell Mussel (GSM) supplement on joint health and osteoarthritis in an older adult population: A double-blind randomized placebo-controlled parallel study.

The aim of this study is to assess the effectiveness of a phospholipid and omega-3 (from krill and GSM) supplement on joint health and osteoarthritis compared to a placebo (glycerol). We will test the hypothesis that supplementation with omega-3 will enhance joint health and quality of life in older adults.
