Antarctic Krill Oil in Joint Health: Inflammatory Context and Heterogeneous Randomized Evidence

Clinical studies of Antarctic krill oil have examined joint discomfort and inflammatory outcomes, with results differing by phenotype, dose and duration. We characterized a phospholipid-rich BCLC® krill oil prepared at low temperature under light-shielded and nitrogen-protected conditions, then considered its formulation quality alongside the human joint-health literature. In the optimized process, separable insolubles before filtration were reduced to 0.31%, and peroxide values remained at 2.5-2.7 meq/kg. Some randomized studies reported changes in inflammatory markers or knee symptoms in mild-to-moderate populations. A 2024 trial of 262 adults with knee osteoarthritis, significant pain and MRI-defined effusion-synovitis, however, found no pain benefit with 2 g/day krill oil over 24 weeks. The variation between trials points to omega-3 exposure, baseline joint pathology and dose as relevant determinants of response.
