Krill Oil for Pain in Elders

Completed · Phase 2

Conditions studied: Chronic Musculoskeletal Pain

In brief

Chronic musculoskeletal pain contributes to mobility disability among older adults. Nutritional interventions, like omega-3 fatty acids, may help manage pain and improve physical function. Supplementation with krill oil may offer advantages to fish oil due to better absorption and additional nutrients. This pilot study aims to assess the feasibility of a clinical trial to determine the impact of krill oil supplementation on pain and function in older adults, informing future research.
