Krill Oil – 18 Benefits of Krill Oil

Omega-3 fats are essential for your health. These healthy fats improve your cholesterol levels, protect you against heart disease, are good for your eyes, and help you burn unwanted body fat.

One of the best sources of omega-3 fatty acids is krill oil. In this article, you can read what krill is, where it comes from and how it can improve your health and weight.

What is krill?

Krill is a collective name for small crustaceans from the sea. It contains an enormous amount of omega-3, in a form that is very well absorbed by our body. We find the small crustaceans in huge quantities in the cold waters of Antarctica.


Is krill safe to take?

Krill is safe to eat. Krill oil is also 100% safe to take.

The waters where the crustaceans live are very clean. Krill is at the bottom of the food chain, so that it is not contaminated with harmful substances. Fish, and in particular fatty fish, are sensitive to pollution. This makes krill oil a better choice than fish oil.

The omega-3 fatty acids from krill oil are better absorbed by our body than the omega-3 fatty acids from fish oil.

At the bottom of this article you will find more reasons krill oil is better than fish oil.

Is krill oil sustainable?

Krill oil is a very sustainable choice. You don’t have to be afraid of overfishing, because there is a huge amount of krill. Krill is one of the species with the largest biomass (the total weight of a group of organisms).

The biomass of Antarctic krill, Euphausia superb, is estimated at 379,000,000 tonnes [1]. To make sure that the krill stock is not overloaded, strict limits have been agreed for the krill catch. This also leaves more than enough krill for whales and penguins. They are also crazy about these crustaceans.

Important to know: krill oil is only sustainable if the by-catch of fish is prevented.

The 18 benefits of krill oil

Krill is not only safe and sustainable but also healthy. Below you can read no less than 18 health benefits of krill oil.

1. Healthy cholesterol levels

Krill oil can help to improve your cholesterol levels if you suffer from high cholesterol. It helps to lower the ‘bad’ LDL cholesterol and to raise the ‘good’ HDL cholesterol.

In addition, krill oil can also help to lower your triglyceride levels. Triglycerides are a type of fats that belong in our blood. However, if your values ​​are too high, they can be harmful. You then have a higher risk of atherosclerosis and heart disease.

2. Fewer inflammations

Many people suffer from chronic inflammation without knowing it. These inflammations do not have clear symptoms. They are therefore also called silent inflammations .

These inflammations are unremarkable, but not harmless. They weaken your immune system and damage your body tissues.

Your diet plays an important role in fighting chronic inflammation. Krill oil can help you with this. The omega 3 it contains has an anti-inflammatory effect. In addition, krill also contains astaxanthin. This is a dye that works as an antioxidant and anti-inflammatory in our body.

3. Relief in arthritis (joint pain)

Thanks to the anti-inflammatory effect of krill oil, krill oil also helps to reduce arthritis complaints [2]. In arthritis there is an inflammation of the joints, which cause pain and may limit your freedom of movement.

This anti-inflammatory effect was proven in a study in mice with arthritis. You can read this study in 2010 in the medical journal BMC Musculoskeletal Disorders [3].

The conclusion of the study is that krill oil helps to prevent swelling and inflammation in mice. We need more research to determine the relationship between krill oil and a reduction in arthritis complaints in humans.

4. Healthy eyes

Omega-3 fatty acids play a major role in keeping our eyes healthy. These fatty acids form an important part of our retina. Research has shown that omega-3 can help prevent macular degeneration [4]. This is a common eye condition in which vision is constantly deteriorating. It mainly occurs among the elderly.

Since krill oil is one of the best sources of omega-3 fatty acids, it contributes to healthy eyes.

5. Good source of antioxidants

Your cells are exposed to oxidation every day, causing them to age. Antioxidants prevent this: they protect your cells. Krill oil contains a very powerful antioxidant: astaxanthin. This antioxidant is many times stronger than other known antioxidants such as vitamin A, vitamin E and lutein.

The amount of antioxidants in a food can be expressed in ORAC (Oxygen Radical Absorptance Capacity) value. Krill oil has an ORAC value of 300. For example, it beats [5]:

  • Zucchini: 180
  • Watermelon: 142
  • Eggplant: 245
  • Garden peas: 260
  • Canned tuna: 90
  • Salmon: 30
  • Eggs: 20

6. Lower risk of heart disease

Antioxidants help keep your heart healthy. But that is not the only way that krill oil helps you to prevent heart disease. The omega 3 fatty acids also play an important role in this.

Omega-3 fatty acids contribute to:

  • A healthy blood pressure
  • Preventing blood clots
  • Preventing plaque in the veins
  • A healthy endothelial function (endothelium is a layer of cells on the inside of your heart, blood vessels and lymph vessels)

All these points promote the health of your heart and blood vessels. Krill oil can help you in this way to keep your heart and blood vessels in top condition.

7. Less menstrual pain

For women who suffer from menstrual pain and PMS (premenstrual syndrome) krill oil has an additional advantage. It can help to reduce these complaints.

In one study, krill oil even turned out to be so effective that the subjects had to take less pain medication [6].

8. A healthy and slim body

Krill oil can help you with a slim body. This has to do with the influence that the omega-3 fatty acids have on your hormone balance. They indirectly ensure that you are less hungry and that you store fat less quickly.

Omega-3 fatty acids also help in burning fat and building lean muscle.

And 10 other benefits

It sounds almost unbelievable how many benefits krill oil can offer. However, krill oil has even more benefits because it is so rich in omega-3.

These are 10 more important benefits of krill oil :

  1. It helps to protect you against depression [7]
  2. It helps to combat non-alcoholic fatty liver [8]
  3. It contributes to a healthy brain [9]
  4. It helps to inhibit deterioration of brain functions in the elderly [10]
  5. It lowers the risk of insulin resistance and type 2 diabetes [11]
  6. It promotes a beautiful, healthy and hydrated skin [12]
  7. It helps to protect your skin against sun damage [13]
  8. It may help to inhibit cancer cell growth [14]
  9. It helps to prevent or reduce dry and red eyes [15]
  10. It is linked to a lower risk of asthma in children and young adults [16]

Krill oil or fish oil?

Krill oil and fish oil have many similarities. With both, omega-3 fatty acids are the most important nutrient they contain. Yet krill oil and fish oil are not the same.

Fish oil is cheaper and is used more. The most research has been done into this oil. Krill oil, however, is catching up. Krill oil beats fish oil in different areas:

  • The omega-3 fatty acids from krill oil are better absorbed by our body than those from fish oil, because they have a different composition.
  • Krill oil contains many antioxidants. The amount of antioxidants in fish oil is negligible.
  • Krill oil is more effective in combating menstrual pain and PMS than fish oil [4].
  • Krill contains fewer harmful substances than fish because the small crustaceans are at the bottom of the food chain.
  • Krill oil is not sensitive to oxidation, unlike fish oil. This can cause free radicals in fish oil.

Easily improve your health

Krill oil can help you improve your health in various ways. And the good thing is: it is very easy to add to your diet in the form of capsules.

With very little effort you can enjoy:

  • Healthier cholesterol levels
  • A lower risk of heart disease

  • Protection of your skin, brain, and eyes
  • A healthier hormone balance (which can help you lose weight)
