Onnit Krill Oil Review – Is This The Best Omega-3 Supplement?

What is Krill Oil?

Harvested from tiny shrimp-like animals found in Antarctic and North Pacific oceans Krill oil is a dietary supplement rich in omega-3 fatty acids, phospholipids and the important carotenoid, astaxanthin essential to your body.

As one of the more potent krill oils available today, Onnit Krill Oil draws on the curative properties of omega-3s found in pure Antarctic krill, EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) to help promote cognition, cardiovascular health, relieve joint pain and discomfort as well as improve mental health and emotional development.

Advantages of Krill Oil vs Fish Oil

Although the use of fish oils have been widely popular, persons are becoming more concerned about toxins found within the oil extract. Because of this, krill oil has become the preferred choice of most individuals for omega-3s.

Much like fish oil, krill oil contains omega-3 polyunsaturated fatty acids, EPA and DHA. However, unlike fish oil, DHA and EPA found within krill oil are bound to phospholipids. This leads to better absorption and delivery of DHA. In addition, krill oil contains a powerful carotenoid antioxidant astaxanthin, that prevents EPA and DHA oxidation.

Research shows that a 300mg daily supplementation of krill oil can decrease inflammation and arthritic symptoms commonly found in patients suffering from arthritis. Further studies also suggest that in addition to lowering triglycerides and raising good HDL cholesterol, krill oil at a much lower dose works just as effectively as compared to other sources of omega-3s.

A more sustainable source of omega-3s due to the fact that it is harvested at the bottom of the food chain and located in one of the most unpolluted oceans due to the almost non-existent occurrence of commercial fishing, Krill Oil is practically free of toxins.

Key Benefits of Krill Oil

Krill oil contains a powerful antioxidant known as astaxanthin which protects your cells from harmful free radicals. The human body produces free radicals whenever you digest food or come in contact with environmentally hazardous materials such as smoke or pollution from the air that you breathe. Normally your body produces antioxidants to combat one free radical at an instance whereas astaxanthin can fight multiple free radicals simultaneously.

  • Boost Heart Health

Much like fish oil, krill oil is made up of fatty acids which help lower cholesterol and triglycerides to improve circulation. Though not conclusive, research has shown that the cardiovascular benefits of krill oil were almost identical to those of fatty fish.

  • Relief of PMS Symptoms

Hailed as a “Wonder Pill” Canadian researchers have found that krill oil offers an all-natural and safe solution to help women cope with the painful and emotional symptoms of premenstrual syndrome, PMS. During the study, some participants were given krill oil throughout their menstrual cycles while the others were given fish oil. The study though argued among researchers show the women who were given krill oil felt less pain than those who took fish oil.

  • Lessen Arthritis Pain

Studies have shown that krill oil can offer relief in arthritis patients by reducing inflammation. In recent study participants who given krill oil for their arthritis pain reported a significant reduction in pain and stiffness between one to two weeks. Though successful the study offers no conclusive evidence that krill oil is superior to fish oil for relieving arthritis symptoms.

  • Cognitive Benefits

Did you know that low levels of omega-3s can bring about memory loss and cognitive skills and supplements such as Onnit Krill Oil improve brain function? Animal studies have proven this. Norwegian researchers found that mice given krill oil supplements performed better at aptitude tests.

  • Reduce the Risk for Skin Cancer

Makers of krill supplements promote krill oil’s ability to improve skin texture, reduce wrinkles, ease the itchy red plaques of psoriasis, strengthen nails, and make hair appear thicker. No credible studies back these claims, however, there may be one benefit. Krill eat algae, and a study conducted in the area of Agricultural and Food Chemistry revealed that mice, when subjected to astaxanthin, were less likely to develop skin cancer.

Krill Oil Ingredients and Use

Krill eat algae that produce an astaxanthin. This gives the krill its own red color. Because astaxanthin is an antioxidant, prevents free radicals from damaging the cells in your body. As a dietary supplement, it is generally recommended to take two soft gels of Onnit Krill Oil daily. This allows a simpler digestive process than other forms of fatty acids subsequently absorbed into the blood and to the brain where it can also protect the cerebrum and nervous system something which many antioxidants cannot do.

Are There Any Dangers With Taking Krill Oil? Let's Look at the Pros and the Cons

  • Pros:

Several recent studies have shown that krill oil is an effective treatment for controlling cholesterol levels. Studies indicate that 1 to 1.5 grams of krill oil taken daily can reduce levels of LDL, the so-called ‘bad’ cholesterol. As with omega-3 fatty acids, it also helps to increase levels of LDL, the ‘good’ cholesterol. An increased 24-hour dosage of up to 3 grams additionally revealed a significant reduction in the levels of blood fat triglycerides.

A low ‘bad’ cholesterol level is essential for maintaining a healthy cardiovascular system and helps prevent heart conditions and cardiac arrests.

  • Cons:

A minor side effect of krill oil, however, is that it slows the speed at which the blood clots and as such may cause problems for individuals who are planning to undergo surgery in the near future. Because of this, it is strongly advised to stop taking krill oil prior to surgery.

It is also recommended that individuals who are taking anticoagulants (blood thinners) or non-steroidal anti-inflammatory medications seek medical advice before taking any krill oil supplement. Likewise, if you are allergic to shrimp or any other form of seafood, use caution when supplementing with krill oil as it may trigger an allergic reaction.

Where to Buy Krill Oil

Endorsed by many athletes who have reported significant benefits while taking krill oil supplements, Onnit Krill Oil can be ordered directly from Onnit or from independent re-sellers found on websites such as on

Final Thoughts

An ideal substitute for fish oil, Onnit Krill Oil is three times more effective at delivering omega-3s to the brain due to its phospholipid complex. Unlike the triglyceride structures found in fish oil, krill phospholipids embrace the naturally occurring chemicals choline and phosphatidylcholine, which help improve how quickly omega-3s reach the brain and the duration they keep working minus that fishy aftertaste.

While krill oil may offer health benefits, you should not take krill oil if you are allergic to shellfish, or if you take blood thinners. Check with your doctor before taking any supplements, including krill oil.
