When it comes to taking an Omega 3 supplement, some people swear by the health benefits of krill oil. Others stand firm with fish oil. In fact, these two fishy oils are a cause of great controversy, with debates raging across the web as to which is the superior source of Omega 3.
Yet, despite multiple debates, the jury is still out, and the questions remains…which is truly better…krill oil or fish oil?

Krill Oil vs. Fish Oil
Although it is true that both supply Omega 3 fatty acids, there are significant differences between the two.
Fish oil comes from a variety of fish, such as herring, mackerel or salmon, and may be wild-caught or farmed (typically it is farmed). While fish oil can be a good source of Omega 3, many supplements tend to use low quality fish oils. These can easily become rancid and cause indigestion. Although they might be cheaper, they are less effective.
A further issue is where it’s sourced from. Fish oil is generally sourced from farmed fish, and this in itself creates a multitude of problems. Recent footage has revealed that in some fish farms, the fish are polluted, deformed and rife with pesticides. Studies have shown that farmed fish contain lesser amounts of omega-3 fatty acids than wild-caught fish, as well as containing 20% less protein.
To make matter worse, farmed fish tend to be fattier with a higher concentration of omega 6. This can result in imbalances in the levels of omega-3 and omega-6 fatty acids, which can eventually cause inflammation in the body.
Krill oil, on the other hand, is sourced from krill. These are small shrimp like crustaceans that live in the clear, pure Antarctic waters. As a result, krill from which the oil is sourced is unpolluted and sustainable.
Many fish oils are derived from farmed fish or polluted waters and need to be processed. In contrast, as krill is sourced from the natural, unpolluted waters of the Antarctic, it requires no processing, and therefore it remains in natural phospholipids form.
When it comes to taking a supplement, absorption it an important factor. The quicker a supplement is absorbed, the faster and more efficiently it can begin to work. Research has shown that fish oil from supplements is not absorbed as well as fish in food form.
In one six-week study, the results showed that the active ingredients of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in fish oil capsules were not as effectively absorbed by the body’s blood plasma fat particles. When you process omega 3, the processing converts the oil to a triglyceride form. As a result, the triglycerides cannot pass through the brain barrier and is absorbed less efficiently, meaning that to absorb a sufficient amount of Omega 3 you would need to take a high dosage. Further studies have verified this, suggesting that there is a difference in bioavailability of EPA and DHA between fish oil and krill oil.
In contrast, omega 3 fatty acids found in krill are bound to phospholipids (a lipid containing a phosphate group in its molecule). The Omega 3 in our brain is phospholipid, therefore if the Omega 3 consumed is of the same type, it is absorbed much more efficiently and directly by the brain. Studies conducted by the Cleveland Clinic have shown that krill oil improves DHA absorption and DHA delivery to the brain. This means less krill oil is needed than fish oil for health befits.
Krill has also been hailed for improving brain boosting capabilities, with one study suggesting that phospholipids and astaxanthin within it might play a role in preventing depression and mental cognition, offering a new approach to treat mental health disorders.
3) Nutritional Value
When it comes to nutritional value, krill oil definitely wins this round. Krill oil has a higher number of antioxidants, including astaxanthin. Known as the king of the carotenoids, astaxanthin ability to fight free radicals is even more powerful than well-known antioxidant powerhouses such as vitamin c or curcumin. This makes krill oil a formidable opponent in the battle against fish oil.
A closer look at the nutritional differences between krill and fish oil also shows that krill oil is a better source of omega 3. Our bodies do not produce enough essential fatty acids (EFAs), therefore it is important that we obtain them through our diet.
That’s where omega 3 comes in. Omega 3 is necessary for healthy brain development, hormone production and even healthy skin, hair and nails. Yet research suggests that about 90 percent of Americans today are deficient in omega-3s. We’re eating too many omega-6s and not enough omega-3s. An imbalance between omega 3 (which is anti-inflammatory) and omega 6 (which is highly inflammatory) leaves the body exposed to every form of inflammatory disease.
One study, which reviewed fish oil supplements in New Zealand, found that almost all supplements contained lower concentrations of n-3 PUFA than claimed on the product label. More worryingly, they were also highly oxidised.
This discrepancy went beyond the New Zealand market, with an international survey including Canada, USA and the UK, finding that more than half of the marine products surveyed contained less than 90% of the n-3 PUFA originally claimed.
The Winner…Krill Oil!
Having reviewed the evidence, krill oil is clearly the winner. Not only is it a superior form of Omega 3, but studies have shown that when it comes to bioavailability it beats fish oil hands down. By being significantly more bioavailable, you are able to consume a smaller dose, yet get a greater effect.
Fish oil is converted into triglycerides, while Krill remains in a phospholipid form, helping it to be easily and efficiently absorbed by the brain.
When it comes to taking a supplement, it is important to do your homework. Finding a supplement you can trust can be difficult, and as evident from the points discussed in this article, many will make false claims about the actual nutritional content you are receiving. However, finding a potent and effectively absorbed source of omega 3 is an important part of your daily supplement routine.
