Krill oil: nutrition facts

Krill oil is rich in omega-3 essential fatty acids, namely eicosapentaenoic acid EPA and docosahexaenoic acid DHA. As Alternative Medical Review states, the most beneficial properties of krill oil are connected with these fatty acids, as they make it anti-inflammatory, anti-thrombotic and anti-atherosclerotic (read more about krill oil benefits).  Omega-3 fatty acids in krill oil are bonded to phospholipids, which makes them easier to be absorbed in the body. Phospholipids make up about 40% of krill oil and contain choline, an essential nutrient used in the cell membranes.  Choline is necessary for fat transportation and metabolism as well as for nerve transmission. Krill oil also contains Vitamin A, Vitamin E and D. There is also canthaxanthin and astaxanthin in krill oil. Always read the label about krill oil nutrition facts to be sure that the krill oil you are buying contains the above-mentioned nutrients.

Krill oil in cholesterol researches

Krill oil benefits have been assessed in a number of researches for regulating cholesterol levels in blood. The Canadian researchers carried out a study published in Alternative Medicine Review in December 2004.  They involved 120 participants, comparing krill oil with fish oil and placebo. Krill oil reduced LDL or ‘bad’ cholesterol by 34 percent as well as increased HDL by 43.5 percent when compared to the placebo. 1-1.5 grams of krill oil lowered LDL more successfully than 3 grams of fish oil. High doses of krill oil (3 grams) reduced blood triglycerides and fish oil didn’t. Is krill oil better than fish oil? The researchers connect the achieved results with the molecular structure of krill oil, phospholipids and astaxanthin in it.
