Fish is one of the foods that must be on the menu at least once a week. And that is because fish oil is a very nutritious element that our bodies need. It helps lower blood pressure[1], lower triglycerides[2], and reduce cholesterol[3]— all benefits for your heart health. Also, because fish oil is rich in omega-3 fatty acids, it benefits your brain health and nerves. Omega 3s fatty acids have been proven to help with memory and significantly help the brain mitigate or slow down age-related mental decline illnesses[4] like Alzheimer’s disease.

However, in this piece, we are looking at krill oil which is not the same but closely related to fish oil since it is still sourced from marine wildlife.

You will learn about health benefits and get seven of the best krill oil supplements.

Read on to learn more.

Best Krill Oil Supplements on The Market in (June. 2023)

What Is Krill Oil?

Krill oil is high in docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA)[5]—the two different types of omega 3s fatty acids. The oil is extracted from Antarctic krill, a small shrimp-like shellfish.

The fatty acids in krill oil, on the other hand, are inherently different from those in fish oil, which may affect how the body processes them.

Krill oil has a different appearance than fish oil. While fish oil usually is yellow, this oil is reddish-brown due to a naturally present antioxidant known as astaxanthin.

In a nutshell, pure krill oil containing natural astaxanthin may assist cardiovascular health, skin protection and restoration[6], inflammation, the therapy of age-related disorders[7] and reduce oxidative stress.

If you compare fish oil and krill oil, krill oil turns out superior in a few instances:

  • The body absorbs krill oil better since it is available as phospholipids and not as triglycerides as found in fish oil. In one randomized trial, people who took krill oil had higher concentrations of EPA and DHA[8]. This claim, however, requires more studies to be deemed conclusive.
  • This type of oil is richer in the antioxidant astaxanthin, which helps fight oxidative stress.

On the flip side, fish oil is more affordable than krill oil when comparing the two. And that is why it is widely used.

Health Benefits of Krill Oil 

Here are the health benefits of krill oil supplementation:

  • As per some studies, krill oil intake can help lower triglycerides, low-density lipoprotein (LDL), or bad cholesterol, two blood lipids that can negatively influence heart health[9] if levels are elevated.
  • Reduced inflammation, improved blood lipid levels, and improved brain function is all advantages of astaxanthin, EPA, and DHA-rich krill oil. The oil may also help treat arthritis[10] and problems linked with premenstrual syndrome[11].
  • A daily dose of this oil provided medical properties in adults with dry eye disease when contrasted to a placebo. According to the researchers, the advantage was related to the long-chain krill oil omega 3s fatty acids.
  • When used to decrease neuroinflammation and cognitive function in high-fat diets, this kind of oil may be more successful than other marine oils at delivering omega 3s. This improved omega-3 absorption, combined with the natural astaxanthin in krill oil, could be beneficial in treating age-related disorders[12], including Parkinson’s and Alzheimer’s.

7 Best Krill Oil Supplements in 2023

According to the Transparent Labs website, both EPA and DHA may help avert or reduce the effects of several ailments, spanning from depression[14] to cardiovascular disease[15].

Elm & Rye Krill Oil comes in a bottle with 30 pills to help consumers enhance joint health and reduce inflammation, limiting movement. With 500 milligrams (mg) of krill oil, it supports greater health in your body and the maximum quantity of how much krill oil per day you need. The corporation outsources lab inspections to an impartial third party to verify that customers get what is advertised on the label and it is free from contamination. 

Its eye-health prowess is owed to astaxanthin[16], an antioxidant and carotenoid that aids in the treatment of glaucoma, eye fatigue, dry eye, and Acute Macular Degeneration (AMD), and other conditions.

1MD KrillMD, being one of our best krill oil supplements, outperforms most other krill oil supplements on the market because it is sourced entirely from Antarctic Krill. It has plenty of astaxanthin, EPA, DHA, and phospholipids, all found in krill.

Chronic inflammation[17] and the oxidative stress[18] that it causes can be fought with astaxanthin.

DHA and EPA can help you live a healthier life by decreasing blood pressure[19], boosting HDL or “good” cholesterol, decreasing triglycerides, and preventing blood clots by preventing platelets[20] from aggregating together.

Due to the highly accessible phospholipids in the blend and the fact that they used krill from the Antarctic ocean, they are one of the best krill oils for decreasing cholesterol. Krill thrive in the Antarctic ocean due to the abundance of food and ice for their healthy growth.

These omega-3 fatty acids are also important for your brain, eye, liver, and bone and joint health.

How We Ranked the Best Krill Oil Brands

While searching for potent krill oil supplements, you must go for the best and most high-quality product to celebrate health benefits. So much so, we chose the best krill oil pills in this post based on the following criteria:

Third-Party Lab Testing

Here, you answer this question: Has a third party evaluated the supplement for authenticity, toxicity, and quality? 

If they have any of the following verifications, the better: United States Pharmacopeia (USP), NSF International, Informed-Sport, and ConsumerLab are among prominent third-party supplement screening companies. The only 3rd party testing and certification program dedicated solely to this type of supplementation is International Krill Oil Standards (IKOS).

A stamp will usually appear on the product, showing that it has undergone third-party testing by this body.

Omega-3 Fatty Acid Content

In this section, we aim to answer three main questions:

  • Is there at least 250 mg of EPA and DHA omega 3s fatty acids in the product?
  • Are there phospholipids in the product to boost the omega-3 absorption rate?
  • Is there any extra oil, filler, or additive that offers additional health benefits to the consumer?

These seven top krill oil supplements reviewed were sufficient in all three categories. They have a good omega 3s fatty acids content, presence of phospholipids, and extras that may help you gain more from this oil supplement naturally.

The Reputation of the Brand

Here, the two main questions are:

  • Is the oil supplement brand well-known and recognized in the industry?
  • Is it getting good feedback for its ingredients, products, and customer service?

A well-known brand, especially one that has been in business for decades, is a good sign. They are probably doing it right, and that is why they are still in business, so this can help. If they are additionally getting overwhelming feedback online, that cements their credibility.

But please be aware that you will most certainly find a couple of bashing feedbacks because not all supplements work for everyone.

Read wide to make an informed decision. But what if you cannot find any feedback about the brand?

Truthfully, some brands are relatively new to the scene, so you may not get as much feedback content on the effectiveness of the product. But should you discredit that brand?

Certainly not! Instead, dive deeper into the ingredient list and conduct more profound research on each ingredient combing through its benefits. If they match your needs, then well and good, and give it a go. But if the science is not conclusive, use a renowned product instead.

Side Effects of Krill Oil

Generally, krill oil intake for adults has been deemed safe, but the studies on its safety are still in infancy. The common side effects are bad breath, fishy taste, loose stool, stomach upsets, and nausea.

But that is not all; the following groups of people may suffer far more severe side effects:

For people healing from surgery, this kind of oil slows down blood clotting, so it’s better to stay away to mitigate bleeding. Such individuals should avoid using this oil before and after surgery for a fortnight.

How Much Krill Oil Should I Take a Day?

The suggested intake of this type of oil is determined by the quantity of DHA and EPA included in the supplement, similar to fish oil. DHA and EPA intake should be between 250 and 500[34] milligrams (mg) per day.

However, studies[35] have indicated that significantly larger dosages of DHA and EPA, up to 4 g per day, may be required for certain persons. Before using any supplement above the suggested dosage, speak with your doctor.

Final Thought

There are a lot of companies that claim to have the best krill oils on the market. And while there are a lot of brands to choose from, selecting the perfect one can be difficult. Regardless, you now have seven brands to choose from, and we’ll throw you two more like bonuses.

The two that are similarly as competent as the above are Krill Oil Plus and Bronson Antarctic Krill oil, but carefully read reviews and examine third-party testing and the ingredient list before making a final decision.

Lastly, supplements should never be used as a meal replacement. For best results, you must maintain a healthy diet and exercise. Most essential, seek medical counsel from your doctor before using these or any other krill oils.
