Krill Oil: Benefits, Properties?
Krill Oil: properties and possible risks
Krill oil is made from small shrimp-like creatures known as krill that live in very cold ocean waters. The krill oil may have beneficial effects for health similar to those of fish oil.
What are the properties of krill oil?
Krill oil contains EPA and DHA, the same omega 3 fatty acids found in fish oil, albeit usually in small amounts. The effects of krill oil have not been studied as thoroughly as those of fish oil. However, some preliminary studies suggest that this oil may have superior properties. For example, krill oil may be better absorbed in the body compared to fish oil.
A study on the oil krill has discovered that it is found to be more effective than fish oil in improving the levels of triglycerides, cholesterol and blood glucose.
Another study found that krill oil, as in the case of omega 3 in general, it may improve symptoms related to rheumatoid arthritis and osteoarthritis, such as pain, stiffness and functional impairment. Also in the course of this study, it was found that krill oil also had lowered levels of C-reactive protein, a marker of inflammation in the body related to heart disease.
Moreover, it seems that the oil is able to relieve the symptoms of premenstrual syndrome. One study found that women, after taking krill oil, needed fewer pain medications.
Because studies show that the fatty acid DHA is beneficial for brain development of the baby, sometimes krill oil is taken by pregnant women or given to children.
Given that krill oil is becoming more and more popular, some scientists have expressed their concern about the possible environmental impact that could result in large-scale fishing of these creatures. The fact krill are an important source of food for many animals, including whales, seals, penguins and other birds.
How krill oil should it take?
Since krill oil is not a proven treatment, there is a standard dose. Some studies have used 1-3 grams per day, sometimes with a daily maintenance dose of 500 milligrams. Therefore, you should always consult your doctor before taking krill oil.
What are the risks related to the intake of krill oil?
Side Effects - Krill oil seems to cause few side effects. Some people may experience bloating, flatulence or diarrhea.
Risks - In the presence of a bleeding disorder or are allergic to shellfish, please consult your doctor before using krill oil. The latter, in fact, can slow down blood clotting and should not be taken during the two weeks before surgery.
Interactions - If you regularly take medications, you should consult your doctor before using krill oil. Like other omega 3 fatty acids, krill oil may cause an increased risk of bleeding and should therefore be used with caution, especially if you are taking anticoagulants (blood thinners). Since krill oil interferes with the blood's ability to clot, it may interact with medications such as anticoagulants, antiplatelet drugs for weight loss. The same risks may arise if the intake of krill oil is concomitant use of supplements such as ginkgo biloba, garlic and ginger.
Although some pregnant women and children take krill oil for brain development and cognitive function, studies have not yet demonstrated the safety in case of long-term use. Therefore, women who are pregnant or are planning to have a baby should consult their doctor before taking krill oil.
