Krill oil is extracted from Antarctic krill (Euphausia superba), a small shellfish similar to shrimp. It is high in protein and low in saturated fat. Krill oil is a sustainable source of omega-3s. The fat content of krill oil ranges from 12 to 50% of its total weight. In whole krill, omega-3s (primarily EPA and DHA) are 19% of its total fat. The phospholipids (fats with a phosphate group) in krill oil protect membranes from free radicals and prevent cell damage.
The Body Absorbs More Fatty Acids from Krill than Fish Oil
Krill oil provides the body with more EPA and DHA than fish oil. In two studies of healthy volunteers (115 and 12 participants), the krill oil group absorbed more EPA than the fish oil group. However, DHA absorption was the same. In contrast to fish oil, krill oil contains free (not bound) DHA and EPA, making them more available for the body to use.
Krill Oil Has Stronger Effects than Fish Oil
In mice, krill oil decreased arachidonic acid (an indicator of inflammation), fatty acid production, and increased insulin sensitivity more than fish oil.
Krill oil also breaks down more fats in mice by blocking enzymes that promote fat creation.
Krill Oil Contains More Nutrients than Fish Oil
The EPA and DHA in krill oil are in the form of phospholipids (fats with a phosphate group), while in fish oil, they are in the form of triglycerides. Phospholipids enhance omega-3 absorption but triglycerides do not. Additionally, the phospholipids in krill oil protect membranes from free radicals and prevent cell damage. Krill oil also uniquely contains the antioxidant astaxanthin, a pigment that protects the unsaturated bonds in EPA and DHA from oxidative damage.
