Krill oil supplements are made from oil extracted from Antarctic krill, containing omega-3 fatty acids, marine lecithin, and astaxanthin. They are used as a natural remedy for various health problems, including arthritis, high cholesterol, and PMS. Krill oil supplements have fewer side effects than fish oil supplements and may alleviate symptoms of certain diseases. However, people with allergies, bleeding disorders, or taking certain medications should consult a medical professional before taking them.
Krill oil supplements are nutritional supplements that contain oil extracted from a species of Antarctic krill commonly found in the Southern Ocean known as Euphausia superba. This krill oil contains omega-3 fatty acids, marine lecithin, and the antioxidant astaxanthin. Krill oil supplements are typically used as an alternative or natural remedy for various health problems, including high cholesterol, dysmenorrhea, PMS, and arthritis, among others.
Antarctic krill are small invertebrates that are similar to shrimp in appearance, live in large swarms, and feed on phytoplankton. Many fish and larger aquatic animals, such as seals, penguins, squid, and whales, consume large amounts of krill. Antarctic krill are generally fished in the Southern Ocean.
The oil extracted from Antarctic krill is sold as a dietary supplement in capsule form. The high level of omega-3 fatty acids in krill oil supplements has made the remedy popular. Omega-3 fatty acids are essential fatty acids that the body needs but cannot produce on its own. These fatty acids are known to ease inflammation and reduce the risk of cancer, arthritis, and heart disease.
The antioxidant astaxanthin found in krill oil supplements is both a nutritional supplement and a natural food coloring due to its red color. Antioxidants help protect cells in the human body from damage caused by free radicals or substances that may be connected to some chronic conditions. Additionally, astaxanthin may also help protect the central nervous system, brain, and eyes from overexposure to free radicals. Astaxanthin can also alleviate symptoms of certain cardiovascular, inflammatory, immune, and neurodegenerative diseases and is believed to work as an anticancer agent in the body.
Arthritis, high cholesterol, and PMS and dysmenorrhea are conditions considered treatable with krill oil supplements. Compared to a placebo, krill oil supplements have been found to be an effective way to reduce the severity of arthritis inflammation and cholesterol levels. Research also suggests that krill oil may relieve symptoms of PMS and dysmenorrhea.
Fish oil supplements also contain high levels of omega-3 fatty acids, but they can cause an upset stomach, a fishy aftertaste, and belching. Krill oil supplements are not known to cause any of these side effects and contain more astaxanthin than fish oil. Krill oil supplements may cause diarrhea or loose stools. People who are allergic to fish or shellfish, have a bleeding disorder, or are taking blood thinners, garlic supplements, or ginko biloba should not take krill oil supplements without the prior consent of a medical professional.
