Krill oil is oil that comes from the tiny crustaceans known as krill, an ocean creature that is less than 2.25 inches (6 centimeters) long. The krill is the main source of sustenance for baleen whales and are high in omega 3 fatty acids. As a good source of these fatty acids, krill oil is often used in supplements, or may be marketed as its own standalone product.
The reason krill oil is so sought after is because of the benefits offered by omega 3 fatty acids. These acids are known to have positive benefits, especially for the heart, which the body cannot produce on its own. While some sorts of oily fish are good sources for these acids, krill oil also has them in abundance. Omega 3 fatty acids are known to help reduce blood pressure and help lower bad cholesterol.
Although no complete studies have been done, krill oil and fish oil are very similar in their design and composition. Those taking fish oil supplements often take 1,600 mg per day. This may also be acceptable for those who wish to take a krill oil supplement.
The advantages of krill oil are hard to understate, according to recent studies. One showed that those taking a krill oil supplement reduced their bad cholesterol readings by 37 percent over those who took a placebo. Further, krill oil is also thought to be able to reduce the symptoms of premenstrual syndrome (PMS) and diabetes.
However, while the omega 3 fatty acids found in krill oil is a big benefit, it is one among many the product offers. Krill oil also contains an antioxidant known as astaxanthin. This antioxidant is thought to protect the body from free radicals, substances that are thought to harm the body in a number of ways. This antioxidant also gives krill and other crustaceans the reddish color.
Still, as with any sort of dietary supplement, some negative side effects may surface for those taking certain medications. Any supplemental use of krill oil should only be done after consultation with a physician. These cases include people taking a drug to thin the blood. Due to the fact that omega 3 fatty acids also work to thin the blood, there may be undesirable effects when the two combine with each other. Those who have allergies to fish or shellfish should also avoid krill oil. Still, despite these concerns, krill oil is generally considered a very safe supplement for the general population.
