Top 10 Krill Oil Supplements 2018 – Omega 3 Fatty Acid Benefits

Full Disclosure

Best Omega 3 Krill Oil Supplements

The most popular supplemental source of omega-3 fatty acids is fish oil, but many people are concerned that these supplements are contaminated with PBC and mercury. In order to avoid this possible contamination, another great source of omega-3 is krill oil supplements. Krill are small crustaceans that are found in the ocean, and krill oil is extracted directly from them.

In addition to having a lower chance of contamination, krill are also more sustainable than most sources of fish oil, and some would argue they are a more ethical source as well. However, this all depends on exactly how the particular oil in question is harvested.

Krill oil also provides a benefit that fish oils do not, which is the ability to provide a compound known as phospholipids that can help to improve your overall health. Phospholipids are a part of the lipid family and are used by the body to create and strengthen cell membranes.

As with any supplement, the actual benefits you will receive depend largely on the actual quality of the product you choose to use. To help you in this endeavor, we have reviewed many of the top-ranked krill oil supplement currently on the market to help you select the right one for your needs.

Nature Made Krill Oil

Nature made is a very well-known brand, and the products it creates seem to be available everywhere. Unfortunately, their krill oil supplement isn’t up to par when it comes to overall quality. It only provides a 300 mg dose of krill oil in each serving, and it also contains very low doses of DHA and EPA.

Phospholipids, which are krill oils primary unique offering, are also very sparse. A good krill oil supplement should also provide astaxanthin, which is a powerful antioxidant found in krill and other marine plant and animal life, but this product contains just a trace level of it that it isn’t even mentioned on the label.

Schiff MegaRed Krill Oil

MegaRed is a popular krill oil supplement, and it provides a respectable level of both DHA and EPA. These levels are actually pretty high compared to the amount of actually krill oil that is in the supplement, but this is partially because that amount is disappointingly low. Every capsule of MegaRad offers 350 mg of krill oil and only about 17 micrograms of astaxanthin.

Bronson Antarctic Krill Oil

Bronson Antarctic Krill Oil has a much better does of actual krill oil at about 500 mg per serving. It also provides a good level of astaxanthin, EPA, and DHA. There are other competitors that provide more per serving in all of these areas, but this is a decent dose and the product is straightforward.

Natrogix Antarctic Krill Oil

Natrogix provides a krill oil supplement that is neither the best nor the worst on our list. The product provides a moderate 500 mg serving of krill oil and a decent level of astaxanthin. One good thing about this product is that it doesn’t include extraneous ingredients and is a simple and pure option. If you’re a purist, then this might be the most appealing choice for you, but otherwise, there are better alternatives out there that are less run-of-the-mill.

NutraBlast Krill Oil

NutraBlast Krill Oil is one of the best options for those who have specifically selected krill oil over fish oil due to fear of contamination. While its 500 mg dose of krill oil isn’t setting any records, it is one of the only options that is marketed as being in line with California’s Proposition 65.

Its label declares this, which means that it follows a strict guideline on purity levels and must be strictly tested for PCBs. PCBs are a type of chemical that is synthetically made and they have been connected to certain cancers. They are also known to be found in certain marine wildlife. If you are extremely concerned with making sure your omega-3 supplements are free of this particular chemical class, this may be the right product for you.

Renew Naturals Antarctic Krill Oil

Renew Naturals provides yet another product that includes a moderate amount of krill oil at 500 mg per serving. However, it does have a relatively high dose of DHA and EPA. If your primary goal for taking krill oil is to get a decent daily dose of the primary omega-3 ingredients (which, for most people, it is) then this product isn’t a bad choice.

The total krill oil content could be better, but overall it’s not bad. This product also contains a decent amount of astaxanthin, but not the highest available n the market.

Jarrow Formulas Krill Oil

Jarrow Formulas provides the highest dose of krill oil per serving so far. Each capsule contains 600 mg, and the suggested serving is actually 2 capsules per day. This provides a whopping 1,200 mg of krill oil.

While this is a pretty big dose of krill oil, it only contains about 0.11 mg of astaxanthin. If the inclusion of astaxanthin is an important benefit for you, then there are other products that contain higher doses.

Viva Naturals Krill Oil

Viva Naturals is another krill oil supplement that provides great levels of all the major ingredients more users are looking for. Each dose contains 165 mg of EPA, 95 mg of DHA, and a massive 1,250 mg of krill oil.

The only real downside to this product is the fact that this dose is divided among 2 soft gel capsules. If you hate taking pills and want to minimize the number you have to swallow, you may not love this offering.

Neptune Krill Oil

Neptune Krill Oil is in a unique situation because the company that makes it has spent a significant amount of money actually researching krill oil to determine its benefits, downsides, and proper dosages. Many of the tests and studies which have discovered the benefits and uses of krill oil are performed using this exact product.

The product provides a 1,000 mg dose of krill oil with equally respectable doses of astaxanthin, EPA, and DHA. If you want to get the best results that are as close as possible to the benefits found in most studies, the best way to do it is to use the same product that was given to the participants.

Antarctic Krill Oil

Antarctic Krill Oil provides a great 1,000 mg dose of krill oil, and it’s probably the best available if you want to make sure you get plenty of phospholipids. The product provides a whopping 400 mg of phospholipids, along with 60 mg of DHA and 128 mg of EPA. A full 1 mg of astaxanthin is also included, which provides great antioxidant qualities and is a pretty high dose compared to most other krill oil supplements.

Krill Oil Benefits And Side Effects

Krill oil is becoming very popular as an alternative to fish oil as a supplemental source of omega-3. It provides phospholipids to increase cell health and astaxanthin as a powerful antioxidant, which you can’t find in most fish oil available on the market.

The use of krill oil is relatively new and there isn’t a ton of research available, but all of the current research suggests that krill oil can be legitimately considered to offer all of the benefits of fish oil with a few added bonuses.


The benefits that users have come to expect from fish oil can also be expected from krill oil since these benefits in both cases are derived from the provision of omega-3 fatty acids. The benefits of omega-3 are well-known and have been proven by a variety of conclusive studies, and they can positively affect a variety of different health concerns.

Omega-3 fatty acids, and specifically DHA and EPA, have been proven to lower the risks of heart disease and increase heart health overall. This was most notably proven by a study that was published by the American Heart Association in 2003. They have also been proven to be beneficial to your mental health.

A review that was published in 2006 on the Journal of Clinical Psychology examined the benefits of omega-3 for preventing and treating depression, and it has also been linked to a decrease in cognitive impairment and decline among the elderly.

There are all well-documented benefits of omega-3, and they can be seen by those using either fish oil or krill oil. The question here is a bit more specific: Does krill oil offer any specific benefits that cannot be achieved with the use of fish oil? Luckily for us, there have been a few studies that have asked this exact question with promising results.

One study was performed on mice in 2010, in which researchers gave the test subjects a case of rheumatoid arthritis. They then divided these mice into 3 different groups. One group was given no treatment, another group was given fish oil supplements, and the third group was given krill oil supplements.

They concluded that the krill oil supplement was the most effective at treating and curing rheumatoid arthritis. This is because the krill oil was able to significantly reduce the inflammation that rheumatoid arthritis causes down to the cellular level. This caused the researchers to determine that krill oil could be an effective treatment for many different types of inflammation.

Additional studies tested this theory among human participants. One randomized trial that was conducted for a period of 2 weeks was able to deliver significant results and was published in the Journal of the American College of Nutrition. This study was conducted by collecting subjects who had either osteoarthritis or rheumatoid arthritis and giving them either 300 mg of krill oil a day or a placebo.

When the blood of each participant was tested at the end of 2 weeks, those who were given krill oil showed a significant reduction in the levels of inflammatory chemicals in their blood. This study was very short, and a much longer study is needed to determine the long-term effects of this treatment. However, these results are very promising and are sufficient to show that krill oil could be an effective treatment for the inflammation that causes joint pain and arthritis.

Another unique benefit of krill oil is that is has been shown to help with the severity of premenstrual syndrome. One company that manufactures and sells krill oil supplements conducted a study which followed women who were taking krill oil supplements for 3 months. The study found that these women reported having fewer symptoms and they had to take fewer medications that are designed to help deal with the pain, bloating, and other symptoms of premenstrual syndrome during those 3 months than they had previously.

We already know that both fish oil and krill oil can lower the risk of cardiovascular diseases, but it is now thought that krill oil might actually be more effective at this than its fish oil alternatives.

A study that was published in the medical journal Alternative Medicine Reviews is 2004 separated participants into 4 groups, and each group was given a placebo, fish oil, a low dose of krill oil, or a high dose of krill oil. Each subject was followed for 90 days, and their cholesterol, blood sugar, and blood triglycerides were all closely observed.

Any of these 3 having high levels can be a sign of an increased risk of cardiovascular disease. The study concluded that when fish oil and krill oil were given in equal doses, krill oil was more effective at reducing triglycerides and cholesterol than fish oil was.

Not every study on krill oil has resoundingly proclaimed its virtues. Stine Ulven and other scientists at the Norwegian Akershus University College performed a study on the comparable effects of krill oil and fish oil in human subjects, and they found that there wasn’t very much difference in the results between the two. Neither product caused metabolic activity to increase significantly, and both products caused a very similar level increase in the omega-3 found in the blood.

It is worth noting, however, that the levels of DHA and EPA in the krill oil were only about two-thirds as high as the levels in the fish oil that was used, but they both achieved the same results. It is possible that this means that the omega-3 found in krill oil is more bioavailable than that in fish oil, so your body can absorb more of it.

Side Effects

Krill oil supplements are very gentle on the body, much like their fish oil alternatives. The only minor side effect that is commonly reported is that a small number of users may experience a slightly upset stomach. There are also some products that can leave a slightly fishy taste in your mouth.

One of the primary reasons that many people chose krill oil over fish oil is that there is a significantly lower likelihood of mercury or PCB contamination. The krill that most krill oil supplements are made from are harvested from Antarctic waters that are extremely cold and are not often traveled by humans.

This means that the water in these regions is not nearly as contaminated as the waters that most fish used in fish oil supplements are sourced from. Many krill oil supplement manufacturers are aware of this concern, and it is not hard to find supplements that are tested for both mercury and PCB levels.

Omega 3 Fatty Acid Recommended Dosage

The majority of krill oil research that is currently available has been funded by krill oil manufacturers, so the dosages used in these studies directly reflect that dosage of the products these companies make. This means that the dosages we have data on are fairly arbitrary, but we do have more to go on than we would if there were no studies available at all.

Keeping this in mind, most studies indicate that you should be using at least 300 mg of krill oil a day to see the desired benefits. Most studies utilize a higher dose than this, though, especially those that include fish oil. When we pair this knowledge with the relative lack of dangerous side effects of krill oil, it’s perfectly safe to keep your dosage closer to 800 mg or 1,200 mg of krill oil each day. This amount gives you a better chance of fully taking advantage of the product’s health benefits.

Most krill oil supplements, especially those of higher quality, come in doses that easily fit within the optimal range. Alternatively, you could also take a smaller dose supplement at multiple times throughout the day.

Top 10 Krill Oil Supplements 2018 Final Words

Krill oil is a fairly new supplement in terms of being widely accepted, and it is slowly overtaking fish oil as the general user’s primary supplement for omega-3 fatty acids. It can also help you fight off inflammation, improve your heart health, and even decrease premenstrual symptoms in women. While it’s still not definitively proven whether or not krill oil is vastly superior to fish oil, it does definitely provide some unique benefits that fish oil cannot give you.

There is still not enough independent research regarding the uses and benefits of krill oil, and more studies will need to be conducted to definitively conclude its long-term benefits, but we already know enough to know that if you’re taking a fish oil supplement now, switching to krill oil is almost certainly an upgrade.
