What exactly is krill oil?
What nutrients does krill oil provide?
Expert comment: “It is the synergy of these nutritional components that makes this oil beneficial for health problems as disparate as cramps and irritability associated with premenstrual syndrome, high cholesterol levels or arthritic joint pain." Dr. Tina Sampalis, Professor of the Department of Experimental Surgery at the University of Montreal.
What are the benefits of krill oil?
- Protects the health of the heart and blood vessels. Omega-3 is lipid-lowering (lowers cholesterol and blood triglycerides), anti-inflammatory and antithrombotic (prevents the formation of clots). It substantially reduces the risk of heart attack and other cardiovascular diseases.
- Prevents atherosclerosis, that is, the accumulation of fats, cholesterol and other substances (plaques) inside the arteries. This reduces the risk of a heart attack or stroke, since plaque can clog the blood vessels and even cause them to rupture.
- Decreases total cholesterol, "bad" cholesterol (LDL) and blood triglycerides. Thus, it reduces the risk of developing a non-alcoholic fatty liver.
- It acts as a neuro-protector, since the Omega-3 fatty acids of krill oil, EPA and DHA, are essential for brain development in infants and children. They also protect against neuro-degenerative conditions, for example, Alzheimer's disease. In addition, EPA and DHA improve memory, concentration and learning.
- Increase the feeling of well-being, improves mood and is associated with a lower incidence of depression.
- It can be useful for treating attention deficit hyperactivity disorder (ADHD).
- Relieves the symptoms of premenstrual syndrome. For example, cramps, irritability and breast tenderness.
- Lowers Inflammation. It is an excellent complementary treatment of rheumatoid arthritis, osteoarthritis and inflammatory bowel disease (Crohn's disease and ulcerative colitis).
- Delays Aging. Krill oil's astaxanthin and Vitamin E are potent antioxidants that counteract oxidative damage. Without adequate doses of antioxidants there is a greater risk of early aging, atherosclerosis, kidney, eye and neurodegenerative diseases, and cancer, among many others.
- Keeps skin healthy. Astaxanthin protects the skin from solar radiation, prevents sunspots and delays the photoaging of the dermis.
- It helps to regulate blood pressure.
- It promotes an adequate development of vision in children and prevents numerous eye diseases in both children and adults. Reduces the risk of age-related macular degeneration, cataracts, dry eye syndrome and corneal ulcers. These benefits are due to the Omega-3 called DHA (docosahexanoic acid) and astaxanthin.

- Seafood allergies.
- Coagulation disorders because it could cause bleeding.
- Presence of chronic diseases (heart, kidney, liver, endocrine).These patients should consult their physicians before starting to take krill oil.
- Pregnant or nursing women and children under 5 years of age.There is not enough evidence that krill oil is safe during these biological stages.
- Consumption of Orlistat.This drug inhibits the absorption of fats and, as a consequence, krill oil would be eliminated without being absorbed.

There are factors that you should evaluate to choose the best krill oil and that go beyond buying the capsules with a less fishy flavour. Some certifications are very important because they relate to the final quality of the supplement or to the company's environmental commitment. The basic criteria to buy an excellent krill oil are:
- Flavour and Aroma
- Method of Oil Extraction
- Certifications of Sustainable Development
- Added Vitamin D
Flavour and Aroma
Although pure krill oil may have an extremely unpleasant taste, the capsules are tasteless and, in certain commercial brands, only a mild fishy aroma can be perceived. Some manufacturers add flavourings to capsule covers to improve their tolerance on the part of consumers.
The liquid krill oil, in its pure state, is always artificially flavoured because its natural flavour would hinder its consumption. In addition, the intense taste can cause belching, reflux and nausea. Capsules and liquid oil come in several flavours: lemon, orange, strawberry and vanilla.
Method of Oil Extraction
The oils extracted by cold pressure are those of better quality. NKO (Neptune Krill Oil) oil is a guarantee of excellence, since by cold extraction they prevent the krill's nutrients from being destroyed. This oil is the only one approved by the FDA (United States Food and Drug Administration).
Certifications of Sustainable Development
Although Antarctic krill is not a species at risk of extinction, it is important to look for certain certifications on the oil label that reflect the manufacturers' environmental commitment. If the product is certified by the Marine Stewardship Council MSC) it means that it has been obtained through sustainable fishing.
Added Vitamin D
Many krill oil supplements are enriched with Vitamin D. This nutrient is essential for bone development and proper bone mineralisation. If krill oil is to be consumed by children or by women of menopausal or postmenopausal age, it is advisable to buy a product that contains Vitamin D.
Krill oil is a wonderful super-food to take care of the entire body because it not only represents one of the best natural sources of Omega-3, but also provides some other very valuable nutrients. It is beneficial for the heart, brain, liver, skin, eyesight, joints and even for the pains associated with premenstrual syndrome.
Another benefit of krill oil is that it has very few contraindications and its adverse effects are almost non-existent. In addition, it is a natural supplement, effective and easy to take. However, not all products are the same and buying krill oil of the highest quality is essential to achieve the desired effects.
