Krill oil is low in both saturated fatty acids and monounsaturated fatty acid and high in polyunsaturated fatty acid including a high proportion of (n-3) fatty acids and particularly EPA and DHA. There are strong evidences that krill oil may improve the comfort of sensitive joints thank to its n-3 fatty acids and phospholipids content. Particularly, after a supplementation with a dietary product containing pure krill oil, a reduction of systemic inflammation, trough reduction of CRP, was concomitantly accompanied by improvement of various clinical scores associated with joint flexibility, comfort and function. Despite this, there are no studies yet on healthy volunteers complaining the symptoms of rheumatologic pathologies, without being ill.
