Krill oil may be one of the most powerful supplements on the market today. Krill oil contains the omega-3 essential fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) along with the potent antioxidant astaxanthin.
High levels of DHA are required for optimum brain and retinal health. DHA is the primary building block of the brain, retina, and central nervous system. Although DHA can be found in the brain and retinas, our bodies cannot produce it. We must acquire DHA from our diets.
Deficiencies of DHA may increase our risk of depression, memory loss, diabetes, attention deficit hyperactivity disorder (ADHD), cystic fibrosis, Alzheimer's disease, autism, nervous system disorders, psychiatric disorders, alcoholism, sleeplessness, and behavioral problems. EPA provides anti-inflammatory benefits.
Pregnant women with deficiencies of DHA and EPA are at increased risk of developing postpartum depression and delivering a baby with lower IQ.
Krill is also a natural source of the vitamins A, D, and E.
Krill oil is derived from miniature shrimp-like marine crustaceans found in oceans worldwide. Krill are most prevalent in cold-water oceans, such as the Antarctic and North Pacific. There are 18 species of krill and an estimated 500 - 750 million tons of krill worldwide - making them the most significant biomass of animals in the world. Krill are commonly one to five centimeters in size and swim in vast swarms. They are food to fish, whales, sharks, seals, penguins, and other sea birds. Krill eat phytoplankton (microscopic plant life). Unlike many fish, krill are low enough on the food chain that they don't pose a threat of containing mercury.
The benefits of krill oil have been studied for at least 20 years.
Clinical studies have found krill oil especially effective when treating heart disease and heart-related health issues. The DHA and EPA found naturally in krill oil dramatically reduce factors of heart disease by lowering high cholesterol, reducing high blood pressure, and inhibiting plaque and blood clots in arteries.
Krill oil reduces LDL (the bad) cholesterol, raises HDL (the good) cholesterol, and helps control blood sugar, which can aid in the prevention and treatment of diabetes.
The anti-inflammatory properties of EPA provide pain relief from rheumatoid arthritis and other joint pains, by reducing stiffness and tenderness in the joints, and increases grip strength.
Krill oil can assist in the prevention and treatment of osteoporosis. EPA increases calcium in the body, which deposits onto bones and improves bone strength.
Research has shown that krill oil can effectively treat a wide variety of common ailments and health concerns.
Krill oil may promote weight loss by controlling blood sugar and lowering high cholesterol. The essential fatty acids DHA and EPA not only lower the risk, but also aid in the treatment of depression and bipolar disorder. Children with ADHD often have low stores of omega-3 fatty acids. Low levels of these essential acids are shown to cause learning and behavioral problems. By increasing amounts of omega-3, researchers found that improvements were made in academic abilities and behavior.
Krill oil helps decrease light sensitivity in those who suffer from intolerance to light.
Omega-3 may help asthma suffers; supplements have been shown to decrease inflammation and increase respiratory function.
DHA and EPA may lower the risk of developing macular degeneration.
Omega-3 fatty acids have also been shown to alleviate problems associated with premenstrual syndrome (PMS). Krill oil can decrease hot flashes, night sweating, and PMS-related pain.
Krill oil may help decrease the risk of certain types of cancer.
In clinical studies, DHA and EPA appear to slow or reverse the early stages of colon cancer. The benefits were not applicable to late stages though. Consuming large quantities of omega-3 acids has shown a significant decrease in risk from dying of breast cancer. Researchers are currently studying the effects of omega-3 combined with vitamins and other nutrients to prevent and treat breast cancer.
As with breast cancer, researchers speculate that omega-3 reduces the chance of developing prostate cancer.
Krill oil provides many benefits over fish oil.
Krill oil and fish oil both contain DHA and EPA. However, krill oil does not contain heavy metals that are harmful to the body. Krill oil contains powerful antioxidants, astaxanthin and vitamins, that are not present in fish oil. Unlike fish oil, krill oil does not cause fishy burps or bloating. Krill oil is a superior choice.
The only downfall is that people allergic to shellfish may have an allergic reaction to krill oil; studies are currently being done on this. With all of the amazing benefits krill oil has to offer, it may just be the next natural superstar supplement.
