Krill oil has a higher concentration of key fatty acids than fish oils, so a smaller daily dose can produce similar results. In krill oil the omega-3's are already connected to fat molecules like the ones in our bodies - phospholipids - so they are "ready to use" and don't require any chemical conversion. This may be why krill oil is so effective at reducing inflammation, cholesterol and triglycerides.
Studies have shown that krill oil can support heart, brain and vision health like other omega-3 sources, and it reduces inflammation and related pain especially in the joints. It can ease emotional and physical symptoms of PMS as well as increasing energy levels and mental sharpness. Not bad for tiny crustaceans!
