Krill Oil and Mood Improvements

(Last Updated On: June 2, 2017)

In this contemporary era, the wellness industry is thriving as more and more individuals seek solutions for their health challenges. In many cases, the health issue that people struggle with pertains to a nutritional deficiency such as a lack of omega-3 fatty acids. Often, individuals who have struggled with this nutritional deficiency have made use of fish oil to attain the omega-3 fatty acids they need. Research now indicates that there may be a much better source of omega-3 fatty acids-krill oil. By learning more about krill oil, people interested in optimizing their level of wellness can take a great stride towards accomplishing this objective.

Krill Oil-The Basics

Krill oil is derived from krill, which are tiny crustaceans found in all oceans, but concentrated heavily in the Arctic and Antarctic polar seas. Krill are a part of the same animal family as lobsters, crabs, and shrimp. More than 80 different types of krill have been identified. Among the known varieties, the Antarctic krill (Euphausia Superba) is the type of krill that one can fish given that it resides in large swarms and swim within the open water. Krill oil comes from Antarctic krill, and its two most important nutrients are omega-3 fatty acids and phospholipid-derived fatty acids (PLFA).

The Importance of Omega-3

Omega-3 fatty acids are an important nutrient for several reasons, including the fact that they can reduce fat levels in the heart and liver. Three studies from 2009 revealed that deficiency in omega-3 fats may precipitate up to 96,000 premature deaths every year, meaning that omega-3 fatty acid consumption may preserve lives. One study regarding krill oil indicates that it is effective in reducing fat levels within the hearts of rats by 42%. Krill oil was also discovered to reduce fat within the liver by 60%. Krill oil’s ability to reduce the presence of fat in the liver is important for several reasons, including the fact that excess fat in the liver can precipitate metabolic syndrome, insulin sensitivity, and type 2 diabetes. Excess fat in the heart can also have adverse health effects such as greater susceptibility to a heart attack.

In addition to preventing the onset of heart attacks and metabolic syndromes, omega-3 fatty acids are important for the nervous system, especially the brain. This is the case because DHA is converted into a substance called neuroprotectants. Individuals who fall prey to Alzheimer’s disease are often found to have a shortage of these substances. Omega-3s also play a critical role in proper eye and brain development for children and infants.

Krill Oil Versus Fish Oil-Which Is Better?

Although many people have relied on fish oil as their primary source of omega-3 fatty acids, research indicates that krill oil is a much superior source of the nutrient. First of all, it appears that krill oil is more effective in providing our bodies with the needed omega-3 fatty acid as well as other antioxidants. Additionally, krill oil does not contain the type of pollutants that have been found in fish oil, namely mercury.

Krill Oil-The Importance of Antioxidants

In addition to providing nutritional supplementation because it contains omega-3 fatty acids, krill oil is importance as a result of one of its antioxidants, astaxanthin. Krill consume algae that produce this antioxidant, and it is responsible for giving them, and other types of crustaceans like shrimp and lobster a pinkish-red color. The fact that krill oil contains antioxidants is important because they protect our cells from damage that results from the presence of free radicals. Free radicals are unstable substances believed to contribute to various chronic conditions. Unlike some other antioxidants, the astaxanthin in krill oil crosses the blood-brain barrier. In so doing, it could theoretically protect the brain, eye and central nervous system from damage resulting from the presence of free radicals.

Krill Oil and Mood

In addition to being a source from which individuals can attain the omega-3 fatty acid, krill oil is believed to have a positive effect on mood. This is the case because both the omega-3 fatty acid and phospholipids help facilitate mental function. When this mental function is impaired, the result can be poor moods. In many cases, individuals who have experienced difficulty with poor moods find that consuming adequate amounts of omega-3 fatty acids results in mood elevation. Since this is the case, krill oil can likely play a primary and effective role in generating positive moods that entail a sense of holistic wellness and thus entail productivity.

Krill Oil For Women

While krill oil can play a positive role in facilitating the health of both men and women, the compound may provide unique benefits for women. Specifically, many pregnant women have reported that consumption of krill oil has helped them maintain a positive mood during pregnancy. Additionally, many women who take krill oil supplements have reported that they help promote a healthy menstrual cycle.

Krill Oil and Anti-Inflammation

Another health benefit that results from krill oil consumption is that it can reduce inflammation within the human body. This is the case because krill oil produces compounds called protectins and resolvins, both of which can help reduce inflammation within the body before it generates excessive damage within the tissues. For this reason, krill oil can be effective in combating diseases that involve inflammation like arthritis.

Other Benefits of Krill Oil

Krill oil has a plethora of other health benefits, some of which include a reduction of stiffness, pain, and functional impairment within people who have inflammatory disorders. The compound is also known to reduce the symptoms for osteoarthritis and rheumatoid. Some of the other health benefits that can result from krill oil consumption include the combating of hyperlipidemia, cognitive dysfunction, brain aging, memory loss, kidney disease, ADHD, and cancer.

Metabolic Gene Assistance

Research has indicated that krill oil is effective in influencing genes. Specifically, one study indicated that krill oil affects the genes responsible for controlling metabolism. Additionally, studies have revealed that krill oil boosts the metabolism of glucose in the liver, promotes lipid metabolism, regulates the mitochondrial respiratory chain, and decreases the synthesis of cholesterol.

Precautions

Individuals who have allergies to seafood should not use krill oil. Also, individuals who have bleeding disorders should not make use of krill oil unless they have the approval of a trained health professional.

Side Effects

Some of the side effects that can result from the use of krill oil include diarrhea, indigestion, and loose stools.
