What Is Krill Oil And How Does It Work?

What Is Krill Oil And How Does It Work? Krill oil supplements have become the most demanded products for consumers interested in protecting their heart, boosting their brain power, and improving their performance on the job, in education, and on the sports field.

As concerns about contamination have plagued the fish oil market, attention has shifted to krill oil as a superior alternative. Krill oil is also bound to phospholipids which makes it much more absorbable in the body and produces better results than fish oil.


Krill are small crustaceans from the Antarctic & North Pacific Oceans. They are similar to shrimp, however, the only edible part is the tail. The tail is a rich source of omega-3 fats, which are healthy fats that the human body does not produce naturally. Numerous scientific studies have validated the power of these fats to help lower cholesterol levels, support brain functions, and nourish all the cells of the body.

Krill oil is taken from the tails of fresh krill pulled from the Antarctic and North Pacific Oceans. The krill are kept fresh until they are ready for processing, then the oil is delivered to consumers in capsule form. Most krill oil products are designed for daily use since the human body requires a steady supply of omega-3 fats.


Antarctic krill oil is able to support all organs of the body due to its rich supply of antioxidants and omega-3 fats. These antioxidants work their way into the system and help eliminate free radicals known to cause disease. High quality Antarctic omega-3 fats are powerful sources of nourishment for the brain, the skin, and other organs in the human body, and it contains the right amount of these super antioxidants.

In order to achieve maximum support and nourishment, a person needs to consume a healthy dose of our krill oil on a daily basis. Since the body does not produce omega-3 fatty acids naturally, it must be fed a regular supply so that your system can do its job effectively.

Krill oil is distributed throughout the body just as food is. Food is broken down, and the nutrients are distributed through a person’s blood flow. When you consume a krill oil supplement, the oil is distributed in the same fashion. The fats in the oil are passed into the brain, the skin, and other area’s of the body where they are needed for nourishment and healing. Antarctic krill oil is pure and compatible with your body. It doesn’t need to be taken with food to deliver great results. It will go where it is needed.

Health Benefits

May Prevent Obesity

Krill oil blocks the endocannabinoid (EC) pathway, which controls appetite, promoting weight loss.

Mice with normal omega-3 levels have normal EC levels, while omega-3-deficient mice have higher endocannabinoid levels.

Krill oil raised omega-3 levels and reduced EC levels in rats [R].

Although krill oil did not affect food intake, it lowered 2-arachidonoylglycerol (2-AG), an EC involved in overeating.

Lowering EC levels reduces the likelihood of overeating, which helps prevent weight gain and obesity.

Lower Cholesterol Levels

Krill oil reduced cholesterol in healthy rats, rats with high levels of fat in the blood, and rats fed a high-cholesterol diet.

n patients with high cholesterol, both low (1-1.5 g) and high (2-3 g) doses of krill oil decreased total cholesterol (by 13 and 18%) compared to fish oil and placebo.

Reduces Inflammation

In a study (DB-RCT) of 90 heart disease and arthritis patients, krill oil reduced C-reactive protein, a marker of inflammation.

Krill oil lowers TNF-α (inflammation marker) in mice fed a high-fat diet.

Astaxanthin in krill oil blocks nitric oxide production, which reduces TNF-α production. However, astaxanthin levels in krill oil may be too low to provide health benefits.

Lowering these markers of inflammation helps prevent oxidative damage and excessive inflammation.

Krill Oil Combats Arthritis

Omega-3s from krill oil reduced inflammatory cytokine levels, which helps prevent arthritis.

In one study (DB-RCT) of 90 heart disease and/or arthritis patients, daily krill oil reduced pain, stiffness, and functional impairment.

Another study (DB-RCT) of 50 patients, krill oil improved mild knee pain and range of motion.

In mice genetically susceptible to arthritis, krill oil reduced arthritis symptoms and development. However, krill oil did not lower inflammatory cytokines.

Protects the Brain

Omega-3s from krill oil help protect the brain. DHA is essential for brain development and EPA improves behavior and mood.

Phospholipids from krill oil have antioxidant and anti-inflammatory properties. They reduce oxidative damage in the brain and help prevent brain disorders such as depression, schizophrenia, dementia, epilepsy, and autism.

Omega-3s in krill oil also prevent brain function decline in elderly people. In a study (DB-RT) of 45 elderly males, krill oil enhanced the function of brain areas that perform calculations and working memory tasks.

Improves Depression Symptoms

Seafood consumption is associated with lower rates of depression.

In rats, krill oil increases brain DHA levels and lowers depression-like behaviors.

In a study (DB-RCT) of 70 patients, krill oil improved PMS-associated depression.

Protects the Heart

The omega-3s in krill oil lower the rate of heart disease.

Additionally, krill oil:

Increases HDL (good) cholesterol in patients with high cholesterol.
Reduces fat and cholesterol levels in patients with high cholesterol and triglycerides.
Reduces blood pressure in rats with high blood pressure, total blood cholesterol in rats fed high-fat diets.

Helps Treat Diabetes

Krill oil reduces risk factors for diabetes, such as insulin resistance and glucose levels.

Krill oil reduced blood glucose levels and improved glucose tolerance and insulin sensitivity in animal studies.

Helps reduce the risk of heart attack in diabetic patients by:

Improving blood tissue function
Lowering C-reactive protein
Increasing HDL (good) cholesterol

In 48 participants with type 2 diabetes, krill oil reduced insulin resistance after four weeks.

Krill Oil Stops Cancer Cell Growth

In human cells, fatty acid extracts from krill oil stopped the growth of colorectal cancer cells.

Since krill oil extract kills cancer cells and is well-tolerated, it is a potential anti-cancer therapy.

Helps Dry Eyes

Low omega-3 intake was associated with dry eye disease (eye pain and vision loss) in a study of 32,000 women.

In a trial (DB-RCT) of 54 participants, krill oil reduced dry eye symptoms, inflammation, and eye redness.

Reduces PMS Symptoms

EPA and DHA lower PMS symptoms such as mood swings, fatigue, and depression.

In a study (DB-RT) of 70 women, krill oil reduced stress, depression, irritability, and use of pain relievers.

Krill Oil Reduces Colitis Symptoms

Colitis is the inflammation of all or part of the colon. By reducing inflammation, krill oil reduces colitis symptoms.

In rats with colitis, krill oil reduced oxidative damage and colon inflammation.


High-quality krill oil supplements are gentle and safe. Antarctic krill oil is from clean waters and has the Best species of krill. This brings you the finest omega 3 krill oil supplement on the planet. It is both highly beneficial and very safe for your growing and developing children.
