How We Ranked The 10 Best Krill Oil Supplements

After going through the reviews, you might wonder what we considered when ranking the krill oil supplements. And we kept these crucial factors in our minds when scrutinizing the options:


The list of ingredients is the first thing that can say whether the product is effective or not. So, the first thing that we checked was the ingredients. If the blend contained any elements that the Food and Drug Administration did not approve, we did not examine the product.

For the ones that did have the right ingredients, we checked the strength. No matter how good the brand might advertise its krill oil product, if the potency of the ingredients is low, it will not be able to offer that many benefits at all. And we prioritized the ones that had the right blend of the essential elements.

Lab Testing and Research

Another factor that plays an essential role in terms of effectiveness is tests. Even with the proper selection of ingredients, some supplements did not offer that much of an effective result. And the brands that do invest their money on tests and lab reports usually offer krill oil products that can provide the most of krill oil.

For that reason, we prioritized the ones that were backed by test reports and clinical tests. And if they offered effective results, they got a higher position on our list.


Plenty of brands promote their krill oil products by stating that they have surpassed different lab results and tests. However, they will offer any information regarding the results. We did not check them out because it is easy to promote stuff by stating such bold claims.

Instead, the ones that got most of our attention were the products that provided accurate information about the test results. The more health information they offered in those tests, the higher the ranking they got.

Advertised Benefits

Even some of the effective krill products claim to offer unexpected and uncommon benefits. They will state that they will cure certain diseases in a matter of weeks. But you should know that no supplements are intended to cure diseases.

Alongside that, many brands claim their offerings can help with weight loss, which is not possible with a krill oil product. For that reason, we did not even check the supplements that were claiming random stuff. Instead, we prioritized the ones that stated known benefits.

Sustainable Sourcing

Most of the krill products will rely on a handful of fishing companies. However, many go a step ahead and source their ingredients from certified sources. Those krill oils are harvested from the pristine waters of the Antarctic Ocean.

We did consider both cases. But our priority went to the brands that were sourcing the ingredients from the certified sources.

What Does Science Say?

Even though krill products have surged in popularity in recent years, scientists and researchers have been studying these oils for an extended amount of time. And these are the findings that they have concluded:

Reduction of Inflammation

This study from 2007 proved that krill oils could lead to a significant drop in inflammation. The research involved older adults where they had to take krill oils. After a couple of doses, the researchers have found that the adults had a substantial drop in CRP levels.

Another study found a similar connection between inflammation and krill oil. In this study, the researchers gave a group 300 mg of krill oil. A different group got placebos. After one month, the group that took the krill oils saw 30% lower inflammation.

Boost Immunity

It is a well-known fact that reduction of inflammation can boost immunity. A study that took place in 2013 showed that krill oils could significantly reduce TNF-a levels. And after that, the immunity system of the participants saw a significant boost too. They were less likely to catch viral diseases.


Multiple studies have found the link between joint health and krill oil. In this specific study, researchers gave krill oil tablets to a group of knee pain participants. After a month, the participants reported that there was a significant reduction in their knee pain.

Additionally, they have claimed that their limitation in the case of mobility was highly uplifted too. They enjoyed an increased range of motion. Other studies have also found that krill oil tablets could reduce arthritis pain.

Side Effects of Krill Oil

Healthy adults will be able to tolerate the krill oils without any issues at all. Different studies have already proved how safe krill oils are. However, that is only applicable when the ingredients are at the recommended dosages. If the krill oils are too strong, they can cause different side effects.

The mild effects that krill oils can cause are fishy burps, fishy breath, upset stomach, bloating, constipation, and constipation. Also, the higher dosages can sometimes suddenly lower cholesterol levels.

Some of the studies have found that it can interact with blood-thinning medications and slow down blood clotting. And this blood clotting problem only occurs when the dosages are too strong. That is why many doctors will recommend against taking krill oil within the first two weeks of surgery.
