The body doesn’t produce all essential nutrients, including omega-3 fatty acids, which must come from your diet. However, getting enough can be challenging due to factors like food availability, cost, and dietary habits.

Krill oil is a commonly used supplement that could help in boosting your omega-3 intake. It has omega-3s in a phospholipid-bound form, which may be easier for the body to absorb compared to traditional fish oil. It also provides astaxanthin antioxidants.

With potential health benefits for heart health, inflammation, and overall wellness, krill oil supplements could potentially support your health goals. However, with so many options on the market, choosing the right one can be difficult.

This guide discusses what makes krill oil unique, key factors to consider when selecting a Krill oil supplement, and a list of 8 best krill supplements to help you decide.

What is Krill Oil?

Krill oil is derived from tiny crustaceans, primarily harvested from the Atlantic Ocean. This oil may serve as an alternative to fish oil, potentially offering similar health benefits while boasting a unique composition. Research shows that 68% of adults and 95% of children in the U.S. don’t consume sufficient omega-3s. Krill oil has omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which contain enhanced absorption capabilities. Krill oil may help in decreasing inflammation and promoting wellness. It could also aid in protecting against oxidative stress, which might reduce the chances of various age-related diseases.

Benefits Of Krill Oil Supplements

  1. They Might Reduce Inflammation

    Krill oil contains fatty acids, particularly EPA and DHA, which are known to have anti-inflammatory properties. These omega-3s may help modulate inflammatory pathways in the body, potentially reducing chronic inflammation associated with conditions like arthritis. By affecting inflammatory molecules such as cytokines and prostaglandins, krill oil supplements may assist in managing inflammation at the cellular level, potentially benefiting you in addressing joint discomfort.

  2. They May Improve Lipid Profiles

    One of the key omega-3s found in krill oil, EPA, has been shown to influence lipid metabolism by lowering triglyceride levels and improving the balance between HDL (good) and LDL (bad) cholesterol. This could help you maintain healthy cholesterol levels and reduce cardiovascular risks. The phospholipid structure of krill oil may also enhance absorption and effectiveness compared to other omega-3 sources.

  3. They Might Support Heart Health

    Taking krill oil supplements may also help in maintaining a healthy heart. DHA, in particular, is involved in the structure of heart cell membranes, helping to improve cardiovascular function. Omega-3s may work by reducing the formation of blood clots, lowering blood pressure, and improving the elasticity of blood vessels, which could contribute to better overall heart health. Krill oil supplements might provide a natural option to help maintain heart function and support your cardiovascular system.

  4. They Could Enhance Brain Function

    Krill oil’s DHA content is important for brain health, as it is a primary component of brain cell membranes and is involved in signaling between brain cells. Research has shown that omega-3s may support cognitive function, improve memory, and help maintain mood stability. These benefits arise from the ability of omega-3s to promote neuroplasticity, which is the brain’s ability to form new connections.

  5. They Could Boost Eye Health

    Regular intake of krill oil might support the health of the retinal cells and could be beneficial for maintaining eye function as one age. The anti-inflammatory effects of omega-3s might also contribute to reducing the risk of age-related eye conditions like macular degeneration.

  6. They Might Promote Skin Health

    Krill oil contains an astaxanthin compound, which could protect your skin from oxidative damage induced by free radicals. Oxidative stress can damage skin cells and speed up the aging process. Astaxanthin may help by neutralizing free radicals, potentially reducing visible signs of aging and promoting healthier, more resilient skin. By taking a krill oil supplement, you might notice improvements in skin hydration and elasticity, although the results might vary from person to person.

  7. They May Improve Joint Health

    The anti-inflammatory properties of krill oil’s omega-3s could also extend to joint health. It might regulate inflammation in the joints, which may reduce stiffness and discomfort, particularly in conditions like osteoarthritis. While research on krill oil specifically is still growing, its potential to improve joint function and flexibility may make it an option for those seeking to support joint health as they age.

How To Select The Best Krill Oil Supplements?

  1. Check for High-Quality Sourcing

    When choosing a krill oil supplement, start by considering where the krill comes from. Antarctic krill is often the preferred source due to the clean, unpolluted waters of the Southern Ocean, where these tiny, shrimp-like creatures are harvested. This environment could minimize the risk of contamination from heavy metals and other toxins that are commonly found in industrialized waters.

    Sustainability is another key factor. Overfishing krill can damage marine ecosystems, so look for products that are certified by organizations like the Marine Stewardship Council (MSC). This certification ensures that the krill oil is sourced in an eco-friendly way, protecting ocean life and maintaining long-term krill populations.

  2. Verify Purity And Freshness

    Purity should also be a priority when selecting krill oil supplements. Contaminants like heavy metals, PCBs, and dioxins can accumulate in marine life, so reputable brands test their products for these harmful substances. Always check if the product meets safety standards and has undergone third-party testing.

    Freshness is just as important. Omega-3 fatty acids, especially in krill oil, are vulnerable to oxidation, which can reduce the oil’s effectiveness and create an unpleasant odor. Look for products with natural antioxidants like astaxanthin, which not only helps maintain freshness but also adds additional health benefits. A fresh krill oil supplement should have no foul smell or taste, indicating it’s been properly preserved.

  3. Consider Dosage

    The appropriate dosage is also crucial for maximizing the health benefits of krill oil. Typically, supplements provide between 500-1000 mg of krill oil per serving, which includes the necessary amount of EPA, DHA, and astaxanthin. If you are targeting specific health issues, like inflammation or high triglycerides, a higher dose may be recommended, but always consult your health expert before adjusting your dosage. Exceeding the recommended dosage might cause gastrointestinal discomfort or an increased chance of bleeding, especially if you’re taking medications that affect blood clotting.

  4. Look For Certification

    To ensure the quality and safety of a krill oil supplement, check for third-party testing and certification. Independent seals from organizations like NSF International, USP, or ConsumerLab provide confidence that the product meets rigorous safety and quality standards.

    If you have dietary restrictions, look for additional certifications such as Non-GMO, Gluten-Free, or Allergen-Free. These can help guarantee that the supplement may suit your dietary needs.

  5. Avoid Additives

    High-quality krill oil supplements should be free of unnecessary additives, fillers, and artificial ingredients. Some manufacturers include flavorings or coatings to mask any fishy taste, but these should not compromise the supplement’s purity or effectiveness.

    Avoid products that list synthetic colors, preservatives, or chemical stabilizers on their ingredient labels. Instead, choose supplements with minimal, natural ingredients to ensure you are getting the purest form of krill oil.

  6. Read Reviews and Reputation

    Customer feedback and a brand’s reputation may provide you with valuable insights into the quality and reliability of a krill oil supplement. Check reviews for any comments about product effectiveness, taste, ease of swallowing, and overall health benefits.

    Look for brands with a long history of positive reviews and a strong commitment to transparency. They should provide clear and detailed labeling and detailed information on sourcing, manufacturing, and testing processes.

  7. Price And Value

    While high-quality krill oil supplements might come at a higher price due to sustainable sourcing, third-party testing, and premium ingredients, this investment is generally worth it. On average, you could expect to pay anywhere from $20 to $82 for a month’s supply of krill oil, depending on the dosage and brand. Higher-end supplements with additional features like enteric coating or added antioxidants might cost a bit more.

    Look for products that offer good value without cutting corners. Bulk purchasing or subscription plans may also help reduce costs without sacrificing quality.

    Be cautious of krill products that seem unusually cheap, as they may use low-quality sourcing or manufacturing processes that could compromise the safety and efficacy of the supplement. Products priced below $15 may indicate potential issues with sourcing or testing, so it’s best to be wary of those, especially if they lack transparency or third-party certifications.

Are Krill Oil Supplements Safe?

Krill oil supplements are typically safe for most people when taken as directed, providing various health benefits because of their high omega-3 fatty acid content. However, some people may experience mild side effects, including digestive discomfort or a fishy aftertaste. Those with fish or shellfish allergies should avoid krill oil, as it’s derived from Antarctic krill. Additionally, krill oil can have a blood-thinning effect, which could be a concern for individuals taking blood thinners or preparing for surgery, so it’s important to consult a healthcare provider beforehand. High doses may also increase the risk of bleeding, emphasizing the need to follow the maker’s recommended dosages. Pregnant or breastfeeding women and those with any existing medical conditions, like bleeding disorders or liver problems, should seek medical advice before using krill oil.

Side Effects Of Krill Oil Supplements

  1. They Might Cause Digestive Issues

    You might experience mild digestive discomfort when taking krill oil, such as bloating, gas, or an upset stomach. These side effects are often due to your body adjusting to the supplement and may subside over time. If digestive issues persist, consider taking krill oil with meals or trying a lower dosage. If you’re sensitive to supplements, starting slowly can help minimize discomfort.

  2. They May Increase The Risk of Bleeding

    Omega-3 fatty acids, including those found in krill oil, have blood-thinning properties that can reduce the risk of clot formation. However, this effect could increase your risk of bleeding, especially if you take high doses or are on blood-thinning medications like aspirin or warfarin. If you’re on such medications or have a bleeding disorder, consult with your doctor before taking krill oil.

  3. They Could Cause A Fishy Aftertaste or Burps

    While krill oil is known for having a milder fishy odor compared to regular fish oil, you may still experience a fishy aftertaste or burps. This could be due to omega-3 fatty acids, which can leave a lingering taste. To reduce this, you can take krill oil with meals or try enteric-coated capsules, which release the oil later in the digestive process to minimize this side effect.

  4. They Might Trigger Allergic Reactions

    Since krill oil is derived from shellfish, if you have a shellfish allergy, you should avoid it. Even if you don’t have a known allergy, there’s still a small chance you could experience allergic reactions, like severe skin rashes, swelling, or difficulty breathing. If you notice any allergic reaction after taking krill oil, stop using it immediately and seek medical help.

  5. They May Interfere With Certain Medications

    Krill oil, like other omega-3 supplements, may interact with certain medications. It could affect blood thinners, medications for high blood pressure, diabetes, or immunosuppressive drugs. If you are on any prescribed medications, it’s crucial to discuss with the doctor before adding krill oil to your routine to avoid potential interactions.

  6. They Could Cause An Increase In Blood Sugar Levels

    Very high doses of omega-3s, including krill oil, might impact blood sugar regulation, especially for people with diabetes. This could lead to slightly elevated blood sugar levels. If you have diabetes or have concerns regarding blood sugar, monitor your levels regularly and consult your healthcare provider to ensure krill oil is a good fit for you.

  7. They Might Affect Liver Function

    In rare cases, high doses of omega-3 supplements, like krill oil, could affect your liver function. You might experience elevated liver enzymes, which could indicate stress on your liver. If you have liver disease or concerns about liver health, it’s best to talk to your healthcare provider before using krill oil regularly.

    While krill oil offers several health benefits, it’s important to be mindful of potential side effects. Your response to the supplement may vary, so if you experience discomfort or have concerns, it’s always a good idea to consult a healthcare professional.
