Krill Oil

    Krill oil is an extract prepared from a species of antarctic krill, euphausia superba. Processed krill oil is commonly offered as a dietary supplement. Two elements of krill oil are omega-3 fats similar to those in fish oil, and phospholipid-derived fats (plfa), primarily phosphatidylcholine (additionally referred to as marine lecithin). (1 )


    Krill oil comes from a tiny, shrimp-like marine animal. It’s abundant in the omega-3 fatty acids eicosapentaenoic acid (epa) and docosahexaenoic acid (dha).

    The advantages of krill oil seem to come from its omega-3 fat content. The body does not produce much of its own omega-3 fatty acids. Omega-3 fats can decrease pain and swelling and also avoid the blood from thickening easily.

    Individuals utilize krill oil for dry eye. It is also utilized for high levels of triglycerides in the blood, high cholesterol, diabetes, anxiety, and numerous other conditions, however there is no good scientific evidence to support a lot of these uses.

    Don’t confused krill oil with algal oil, cod liver oil, fish oil, or shark liver oil. These are not the exact same. (2 ).


    In the last couple of years there has actually been a noticeable boost in both the promotion and research study of krill oil for its purported health advantages, including the management and treatment of conditions, such as hyperlipidemia, swelling, and arthritis. Furthermore, due to the fact that krill oil includes the same omega-3 fats eicosapentaenoic acid (epa) and docosahexaenoic acid (dha) found in fish and fish oil, krill oil is deemed a feasible alternative to fish oil to deliver the health advantages associated with epa and dha. The following review supplies a summary of the currently available 10 peer-reviewed human medical research studies on krill oil, its safety, in addition to a quick summary of the commercial krill oil market. (3 ).

    Krill vs. Fish oil

    While krill and fish oil both have dha and epa, it’s believed that those omega-3 fatty acids discovered in krill oil have a greater bioavailability– or rate of absorption in your body– than fish oil.

    It might have something to do with the dha and epa being found as particles called phospholipids in krill oil. In fish oil, the dha and epa are saved in the form of triglycerides.

    More research is needed to determine the exact reason krill oil might be absorbed more quickly. (4 ).

    Advantages of krill oil

    Krill oil is a supplement that is quickly gaining appeal as an option to fish oil.

    It is made from krill, a kind of little shellfish consumed by whales, penguins and other sea animals.

    Like fish oil, it provides docosahexaenoic acid (dha) and eicosapentaenoic acid (epa), kinds of omega-3 fats discovered only in marine sources. They have important functions in the body and are connected to a variety of health advantages.

    Excellent source of healthy fats

    Both krill oil and fish oil contain the omega-3 fats epa and dha.

    Nevertheless, some proof recommends that the fats found in krill oil might be much easier for the body to use than those from fish oil, since the majority of omega-3 fats in fish oil are stored in the form of triglycerides.

    On the other hand, a big part of the omega-3 fats in krill oil can be discovered in the form of particles called phospholipids, which may be much easier to take in into the blood stream.

    A couple of studies found that krill oil was more effective than fish oil at raising omega-3 levels, and assumed that their varying forms of omega-3 fats might be why.

    Another research study carefully matched the amounts of epa and dha in krill oil and fish oil, and discovered that the oils were equally effective at raising levels of omega-3s in the blood.

    More research study is needed to identify whether krill oil is in fact a more efficient, bioavailable source of omega-3 fats than fish oil.


    Krill oil is an outstanding source of healthy fats. The omega-3 fats in krill oil might be much easier to absorb than those in fish oil, however more research studies are required to state for sure.

    Can assist fight inflammation

    Omega-3 fatty acids like those discovered in krill oil have actually been shown to have crucial anti-inflammatory functions in the body.

    In fact, krill oil might be much more reliable at battling inflammation than other marine omega-3 sources due to the fact that it seems easier for the body to use.

    What’s more, krill oil contains a pink-orange pigment called astaxanthin, which has anti-inflammatory and antioxidant effects.

    A couple of studies have actually started to check out the specific results of krill oil on swelling.

    One test-tube study discovered that it decreased the production of inflammation-causing particles when harmful germs were introduced to human intestinal tract cells.

    A research study of 25 individuals with somewhat raised blood fat levels found that taking 1,000-mg supplements of krill oil daily improved a marker of inflammation a lot more efficiently than a 2,000-mg daily supplement of purified omega-3s.

    In addition, a study of 90 people with persistent inflammation found that taking 300 mg of krill oil daily was enough to decrease a marker of swelling by approximately 30% after one month.

    Although there are just a couple of research studies investigating krill oil and swelling, they have actually shown possibly useful outcomes.


    Krill oil consists of inflammation-fighting omega-3 fats and an antioxidant called astaxanthin. Just a few studies have actually particularly investigated the impacts of krill oil on swelling, however they have all discovered advantageous effects.

    May decrease arthritis and joint discomfort

    Because krill oil seems to help reduce swelling, it might likewise enhance arthritis symptoms and joint discomfort, which typically arise from swelling.

    Additionally, scientists studied the impacts of krill oil in mice with arthritis. When the mice took krill oil, they had actually enhanced arthritis scores, less swelling and less inflammatory cells in their joints.

    While more research studies are needed to support these outcomes, krill oil appears to have good capacity as an additional treatment for arthritis and joint pain.


    A number of animal and human research studies have actually discovered that taking krill oil supplements assists enhance joint pain and arthritis signs, though more research studies are required.

    Could enhance blood lipids and heart health

    Omega-3 fats, and dha and epa particularly, are thought about heart-healthy.

    Research study has shown that fish oil might improve blood lipid levels, and krill oil appears to be efficient as well. Studies have shown it might be particularly efficient at reducing levels of triglycerides and other blood fats.

    One study compared the impacts of krill oil and purified omega-3s on cholesterol and triglyceride levels.

    Only krill oil raised “excellent” high-density-lipoprotein (hdl) cholesterol. It was likewise more efficient at reducing a marker of swelling, even though the dosage was much lower. On the other hand, the pure omega-3s were more effective at reducing triglycerides.

    A recent review of seven research studies concluded that krill oil is effective at lowering “bad” ldl cholesterol and triglycerides, and may increase “great” hdl cholesterol, too.

    Another research study compared krill oil to olive oil and found that krill oil substantially enhanced insulin resistance scores, as well as the function of the lining of the blood vessels.

    More long-term studies are needed to investigate how krill oil affects the risk of heart disease. However based on the proof so far, it appears efficient at enhancing specific known danger factors.


    Research studies have actually found that krill oil, like other sources of omega-3 fats, may work at improving blood lipid levels and other risk aspects for heart problem.

    May assist handle pms signs

    One study compared the effects of krill oil and fish oil in ladies diagnosed with pms.

    The research study discovered that while both supplements led to statistically significant enhancements in signs, females taking krill oil took considerably less pain medication than women taking fish oil.

    This research study suggests that krill oil may be at least as effective as other sources of omega-3 fats at enhancing pms signs.
