An Overview of Krill Oil Supplements
There are several things you’ll want to know when considering a krill oil supplement.
So, what are Krill? They’re small, shrimp-like crustaceans with the scientific name Euphausia superba. They have a pink appearance which is caused by the plankton they eat. Krill are a food source for a wide variety of cold-water animals including whales, penguins, fish, squid and more.
Krill Oil is also used as a food source for people, too. The Japanese have been using Krill (called Okiami) as a food source since the 19th century. Krill is also popular is both South Korea and Taiwan.
What’s in Krill Oil?
Krill contain the Omega-3 polyunsaturated fatty acids EPA and DHA.(1) These are the same fatty acids found in fish as well as some vegetables and other plants. Krill Oil also contains Phospholipid fatty acids, which help with Omega-3 absorption. Finally, Krill Oil contains an antioxidant called astaxanthin which helps remove free radicals.(2)
Krill Oil Benefits
Promotes Cardiovascular Health
Omega-3 helps improve heart health in several ways. Regular use reduces blood vessel inflammation. Plus, Omega-3 lowers the rate of bad LDL cholesterol while also raising the levels of good HDL cholesterol. Krill oil also benefits diabetics by reducing inflammation and blood sugar.
Note that people on blood thinners should first talk to their doctor before taking Krill Oil supplements. Krill Oil helps prevent the development of blood clots. While normally that’s a benefit, it can be a potential problem for anyone currently taking blood thinners.
Helps Prevent Arthritis and Other Inflammation
Omega-3 turns into a hormone called eicosanoid. This hormone controls the levels of prostaglandins, a natural inflammatory which reduces CRP levels.
Don’t worry too much about all the scientific terms. Just know that Omega-3 helps reduce inflammation throughout the body. Daily use can help increase mobility while also reducing pain for arthritis sufferers.
Helps Promote Fetus Development
Pregnant women are often encouraged to take a Krill Oil supplement. Omega-3 helps the growing fetus develop a healthy nervous system, brain and eyes. Unlike fish oil, you don’t have to worry about any mercury harming the fetus. Of course, pregnant women will want to consult with their doctor before taking any supplements, including Krill Oil. (3)
Krill Oil helps the liver function properly. The liver is responsible for the body’s detoxification. Regular use of Krill Oil helps the liver remove toxins from your bloodstream efficiently. (Source)
The Difference between Krill Oil and Fish Oil
Certain fish may contain mercury, which can be especially harmful to pregnant women and young children. The FDA recommends limiting potential exposure by eating no more than six ounces of fish per week. Unfortunately, daily use of fish oil can potentially exceed this level. (4)
Krill Oil contains a drastically reduced risk of mercury exposure. This is because Krill are far lower on the food chain than fish. So Krill generally contain lower levels of both mercury and other pollutants.
Plus, the Omega-3 fatty acids in Krill Oil are absorbed differently than the ones found in Fish Oil. Krill Oil Omega-3 is absorbed in phospholipid form. This helps regulate cholesterol levels. Krill Oil is generally more effective than Fish Oil is helping to reduce artery and cardiovascular disease.
There are a few precautions you’ll want to keep in mind before taking Krill Oil. First, you should never take more than the recommended dosage. Also, Krill Oil should be avoided by anyone with a fish or shrimp allergy. Consult with your doctor to ensure the supplement won’t conflict with any medications you’re currently taking.
