The Norwegian description of krill is "young fry of fish". Krill can be found in large swarms that may contain 1 million animals in each cubic meter of seawater. This population density is what makes Krill ideal for harvesting and for manufacturing products like krill oil. Krill oil is has the same benefits of fish oil but with some unique differences.
Exceptional Nutrients in Krill Oil
One of the greatest benefits of krill oil that really sets it apart from fish oil and other supplements is that it contains astaxanthin. Astaxanthin is one of the strongest antioxidants we have. Antioxidants, as we know, make sure that our cells are not bombarded with harmful free radicals. Krill eat algae that contain astaxanthin and are in turn eaten by salmon, shrimp other crustaceans like lobster. Astaxanthin gives them their pink color. The presence of astaxanthin is just one reason to put these sea creatures into the healthy food category. Since these sea creatures get their astaxanthin from krill, it follows that krill oil would be one of the best natural sources of Astaxanthin. This gives krill oil the weapons necessary to fight inflammation and a host of related problems like skin damage by UV rays and muscle soreness.
Krill oil contains phosphatidal choline, a phospholipid. Phospholipids in your cell membranes help communication between your cells. Numerous studies show the importance of Choline in brain development. Many doctors advise pregnant mothers to take Choline to ensure the baby’s brain development.
Omega Fatty Acids
They have been the buzz in health awareness for a long time. That’s because both Omega 3 and Omega 6 fatty acids are crucial to fight infection and inflammation-related diseases. Like fish oil, krill oil also contains the omega-3 fatty acids, eicosapentaenoic acid (EPA) and decosahexaenoic acid (DHA). In krill oil these fatty acids are found in phospholipids, resulting in the absorption and distribution of a higher proportion of EPA and DHA when compared to fish oil where EPA and DHA are found in triglycerides. EPA and DHA are found in higher potency in krill oil and without the fishy smell and flavor.
Krill Oil Health Benefits
Krill oil is known to provide health benefits such as:
In a study published in June 2010, it was found that krill oil may be a useful intervention strategy against signs of inflammatory arthritis. An earlier study in the Journal of the American College of Nutrition tested the effectiveness of krill oil (300 mg daily) in comparison to a placebo and found that krill oil was effectively reduced symptoms of arthritis and inflammation. Even if you don’t have arthritis, krill oil may help reduce back and joint pains and swelling.
Healthy Cholesterol Regulation
A high level of LDL (that is "bad" cholesterol) is bad because it indicates a greater risk of heart disease. In a study on the effects of krill oil on cholesterol levels of 120 people who were tested by administering krill oil, fish oil or a placebo—it was found that krill oil lowered LDL cholesterol by 34% and boosted HDL ("good") cholesterol by 43.5% compared to the placebo. Surprisingly fish oil reduced LDL cholesterol by a mere 4.6% and increased HDL cholesterol by 4.2%.
Brain Development and Functions
The omega-3 fatty acids and choline are important for normal brain development and brain functions. The beneficial impact of both these nutrients appears to improve cognition, memory, mood and behavior.
Some studies show the regular intake of EPA and DHA may help those who suffer from mood swings, depression and other related mental disorders.
PMS (Premenstrual Syndrome)
There is some evidence that suggests two grams of krill oil a day may relieve symptoms of PMS.
Eczema is common skin ailment that can be the result of fatty acid imbalance. Krill oil, since it contains a greater amount of omega 3 fatty acids is more effective than fish oil in curing eczema. It has also been found to make skin healthier.
Helps Fight Signs of Aging
Krill oil contains the antioxidant vitamins, A and E along with astaxanthin. These help fight free radical activity in the body.
