Krill Oil Guide
Health benefits, dosage & cautions
Fish oil based omega-3 supplements have been popular among people for many years. And for a reason, as it’s been much studied for its health benefits for i.a. heart, brain, joints, cognitive functions and even hormonal balance.
In the past years, krill oil has become more and more popular as an alternative omega-3 source among the health conscious people. There are two important reasons why people choose krill oil over fish oil - first, it's a pure and clean source of omega-3 fatty acids, and secondly, it’s said to absorb more efficiently. (1)
Krill oil comes from the Euphausian crustaceans, which can be found from the pristine waters of the Antarctic Ocean. Like fish oil, it’s rich in omega-3 fatty acids called EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid). (2)
One reason why krill oil’s fatty acids are said to penetrate better into cell membranes is because they are phospholipid formed.
Why have we chosen krill oil?
We want to use the purest ingredients we can find. We know that our krill oil is 100% pure & natural source of omega-3s. And besides that, we know exactly where our krill comes from – the krill we use is sustainably harvested and traceable Antarctic krill.
Krill oil - a safe source of EPA and DHA fatty acids
Omega-3 fatty acids called EPA and DHA are the most studied fatty acids. Especially EPA and DHA are shown to have many health benefits. Many studies have revealed that the intake of these fatty acids is important for the normal functioning of eyes, heart, liver and brain. Krill oil contains EPA and DHA but also phospholipids and astaxanthin, which all have positive health effects.
Krill oil's fatty acids are phospholipids. In fish oil these same fatty acids are in the form of triglycerides. The form of fatty acids is connected to the absorption of important omega-3 nutrients, and phospholipids are said to absorb better than triglycerides.
Phospholipids can be described as cars, which carry omega-3 fatty acids to cells - they help omega-3 fatty acids to penetrate into cell membranes. The cell membranes are complex and they prevent many nutrients from entering into cells. Thanks to phospholipids, nutrients and fatty acids get inside the cells more easily.
Choline is an essential nutrient for proper function of the nervous system, muscles and eyes. It also helps liver to stay healthy and it contributes to lipid metabolism. Lately, a study about choline and it's connection to brain health and dementia has been published. It is the first study that reveals choline’s connection to dementia. Choline is possibly one of the nutrients that may prevent dementia. (3)
Human body is not able to produce enough choline, so it is essential to obtain it through the diet.
Astaxanthin is krill oil’s own antioxidant which also gives a reddish color to krill oil capsules. It’s a natural preservative, which protects fatty acids form oxidation - thus krill oil doesn’t need any other additives to stay good.
Thanks to phospholipids, omega-3 fatty acids in krill oil are more effective and stable. The phospholipid formed fatty acids also allow smaller capsules.
No fishy burps!
Unlike fish oil, krill oil’s phospholipid formed fatty acids are easily mixed with stomach fluids and they do not cause any fishy burps, produce reflux or cause stomach ache.
WESTERN DIET CAUSES INADEQUATE INTAKE OF OMEGA-3
A study published in the journal Progress in Lipid Research found that 97% of the world's population don’t have adequate levels of omega-3 fatty acids. (4)
The typical western diet has been claimed to be one of the reasons why people are consuming much less omega-3 in many countries.
Another study in 2017 showed that many people in the United States and in Germany had inadequate knowledge of the benefits of omega-3 fatty acids. 98% of the study’s attendants had lower levels of important omega-3 fatty acids than is needed to prevent & reduce heart and cardiovascular problems (5).
Omega-3 fatty acids are essential for a healthy heart and cardiovascular health.
A recent review of seven studies concluded that krill oil is effective in reducing "bad" LDL cholesterol and triglycerides, and can also increase "good" HDL cholesterol. (6)
Omega-3 fatty acids EPA and DHA have plenty of EFSA approved health claims. They contribute to obtain normal triglyceride levels in the blood and help to obtain normal blood pressure. DHA is good for the normal vision and DHA together with EPA intake contribute to normal brain function.
Overall omega-3 fatty acids are an important source of good fats that are essential for normal health.
Krill oil to fight inflammation?
The benefits of omega-3 fatty acids against inflammation have been increasingly investigated. Attention has been directed to krill oil in particular, mainly because it’s rich in phospholipids and astaxanthin.
One study found that it reduced the production of molecules that cause inflammation when harmful bacteria were introduced into the human intestinal cells. (7)
It may also help with knee pain
A study with 50 participants, who suffered from mild knee pain, found that after 30 days supplementation of krill oil attendants had less pain and stiffness. (8)
How much krill oil should I take?
Dietary recommendations for EPA and DHA are between 250 and 500 mg/day. The recommendations by EFSA are based on the recommended amount that supports cardiovascular health and contributes normal function of heart, brain and vision. This amount is recommended to be adjusted to your personal diet. (9)
Krill oil is safe to people in most cases, but we recommend to consider supplementation in certain circumstances like (10):
Pregnancy and breast-feeding:
There is not enough information about the use of krill oil supplements during pregnancy and breast-feeding. Stay on the safe side and avoid use. Usage only if recommended by a doctor.
Because krill oil can slow blood clotting, there is a concern that it might increase the risk of bleeding in people with bleeding disorders. Until more is known, people with such conditions should use krill oil cautiously.
Because krill oil can slow blood clotting, there is concern that it might increase the risk of bleeding during and after surgery. Stop using krill oil at least 2 weeks before a scheduled surgery.
Krill oil might lower blood sugar levels in people with diabetes. Watch for signs of low blood sugar (hypoglycemia) and monitor your blood sugar carefully if you have diabetes and you use krill oil.
Krill oil might lower how well insulin works in people who are overweight or obese. This might increase the risk of developing diabetes or heart disease.
Some people who are allergic to seafood might also be allergic to krill oil supplements. There is no reliable information showing how likely people with seafood allergy are to have an allergic reaction to krill oil; however, until more is known, avoid using krill oil or use it cautiously if you have a seafood allergy.
