Krill Oil is a type of zooplankton mainly found in regions of Antarctica and Arctic. The gender is called Euphasia Superba and looks like a small shrimp. As a microorganism belongs to the basis of food chain. Based on that, it is believed that krill are not burdened with heavy metals, environmental pollutants and other toxic substances such as mercury, dioxins and PCBs (Polychlorinated Biphenyls) in comparison with big fish.
The nutritional benefits of Krill Oil have emerged from numerous studies in recent years. The reason lies in the nutritional value of the Krill oil regarding the concentration of omega-3 fatty acids (Krill omega-3) and the antioxidant properties due to vitamins and astaxanthin concentration. The most common source of omega-3 fatty acids are fish oils. Many studies have shown that krill oil is equally, if not more rich in EPA (eicosapentaenoic acid) and DHA (dosoexanoiko acid), two polyunsaturated fatty acids that are considered as essential for humans. As essential fatty acids, are defined those that can be obtained from diet only, because body is unable to synthesize them from precursor molecules.
Their main action of EPA and DHA is their positive effect on
- cardiovascular system
- mental health
- inflammatory conditions
- hormonal disorders, such as premenstrual syndrome
Omega-3 fatty acids promote cardiovascular health due to their effect on the atherogenic blood lipids and their ability to maintain the integrity of the arteries. In specific, studies have shown that supplementation of omega-3 fatty acids reduces serum triglyceride levels, LDL cholesterol (bad), while increases HDL cholesterol levels (good). Recent reports demonstrate benefit of omega-3 fatty acids supplementation in fatty liver disease.
Supplementation of EPA and DHA, has further shown benefits in depressive symptoms, mental acuity, function and vigorousness. They also improve energy and vigorousness and generally enhance mood. There are data which support that omega-3 fatty acid supplements may help treating migraines and symptoms of premenstrual syndrome, such as pain, irritability and nervousness. A very important feature of EPA and DHA is their potent anti-inflammatory properties. Many studies have shown that omega-3 help to reduce inflammation, especially in cases of arthritis, Raynaud’s syndrome, and cardiovascular disease.
The main difference between fish and Krill oil is the bioavailability of omega-3 fatty acids. It has been shown in studies that Krill oil provides higher absorption and better bioavailability of EPA and DHA while there are required smaller amounts of oil. The reason is that fatty acids of Krill are in a free form of phospholipids, in contrast with triglycerides that are mainly found in fish oils.
Krill Oil also contains fat soluble antioxidants, such as vitamins A and E and astaxanthin. The role of antioxidant in oil, either they exist naturally or are post-added in packging, serves in the integrity of fatty acids from oxidation. The process of fatty acid oxidation is called rancidity and is an unfavorable for the quality of oil. The main difference between fish and Krill oil lies in the concentration of the first in astaxanthin, compound found mostly in seafood. Astaxanthin is a pigment compound with very good antioxidant properties which belongs to the family of carotenoids. Astaxanthin contributes to antioxidant mechanisms of body, reduces free radicals, promotes cardiovascular health and skin protection from ultraviolet radiation while participates in eye health from degenerative diseases. Some reports have shown benefit from astaxanthin supplementation even in infertility.
Krill Oil is a seafood extract, the nutritional value of which is making it the most powerful ally of body and spirit!
