What Is Krill Oil?
If you are concerned with your health, you may have considered taking an all-natural krill oil supplement. Krill are small crustaceans similar to shrimp that live in the ocean and are eaten by many marine species such as, penguins, seals, fish, and squid. Although most krill is used for aquaculture, sport fish bait, aquarium feeds, or food in Japan, much of it is used for krill oil extraction for nutritional supplements.
Krill oil is an excellent source of omega-3 fatty acids, which makes it popular as a nutritional supplement. Omega-3 fatty acids are also contained in other cold water fish like salmon, herring, mackerel, and sardines. They can affect cardio health through the management of cholesterol. Inflammation, respiratory health, immune health, eye health and brain development in infants, mood, and more can also be positively affected by the use of krill oil.
Krill oil also contains astaxanthin, the anti-oxidants that give shrimp, lobsters, and krill their pink color. These anti-oxidants can protect the cells in your body from free radical damage, which is caused by unstable substances that can contribute to chronic health problems. Astaxanthin can move across the blood brain barrier and can help to protect the eyes, central nervous system, and brain from free radical damage.

Krill oil also has powerful antioxidant astaxanthin whereas fish oil supplements do not contain. Astaxanthin is known to be beneficial for body in many different ways.Krill oil is often used to remedy high cholesterol levels. Researchers conducted a study with 120 people who were given fish oil, krill oil, or placebo. Users who took krill oil had a reduction in their bad LDL cholesterol of 34% and an increase in good HDL cholesterol of 43.5%, compared to the users who took the placebo. The users who took fish oil reduced their LDL cholesterol at 4.6%, while their HDL cholesterol increased by 4.2%. The krill oil was also found to lower triglycerides.
The Journal of the American College of Nutrition performed another study in which they gave users 300mg of krill oil each day to compare to a placebo group, and discovered that krill oil effectively reduced arthritis symptoms and inflammation. There has been some preliminary research that suggests premenstrual syndrome symptoms may be reduced by krill oil as well, and more research should be conducted for other health benefits of Krill Oil in women.
Although the typical dose of krill oil contains less EPA and DHA than fish oil, the krill oil’s omega-3 fatty acids are bonded to phospholipids, not triglycerides. This gives unique biological attributes when ingested by humans so they are more easily absorbed and retained by the body.
