The great Krill oil Versus fish oil debate. Who wins?
There has been much noise made lately about the benefits of Krill oil, and many people have started taking Krill oil capsules as a result. It is said that Krill oil contains more beneficial components, and as a result there has been a bit of a Krill oil versus fish oil debate. So should you be taking Krill oil or fish oil?
Perhaps we should begin by discussing exactly what Krill oil is. Krill are tiny shrimplike creatures that live in the colder areas of our oceans. Whales eat them by the ton, and they also make up a part of the diet of humans, mainly the Japanese and Russians.
Lets say at the start that the important Omega 3 essential fatty acids are DHA and EPA. Both Krill and fish oil are a source of these important Omega-3 fats.
So if both oils contain both EPA and DHA how do you choose one or the other?
1. Compare The Cost Of The DHA That You Are Getting.
It is generally considered that DHA is more important to your health than EPA, though EPA is certainly important as well. Around 60% of your brain is fat, and DHA is the most prevalent, and adding DHA and EPA to your diet promotes a range of health benefits including benefits to your mental function as well as reducing the risk of death from heart disease, helping your cholesterol levels and helping you reduce weight, and much more.
When you’re buying quality Omega 3 oil supplements you are primarily buying DHA. So one of the most important parts of comparing the different oil capsules is to assess the cost of the DHA that you’re buying. This is simply a matter of making a mathematical calculation of the amount of DHA in each capsule as a proportion of the price.
If you make a comparison of Krill oil compared to fish oil capsules you’ll find that the DHA that you’re buying in Krill oil softgels is significantly more expensive than the DHA you are buying in fish oil supplements. In fact it is over 5 times more expensive to buy DHA in Krill oil form that it is as fish oil.
Krill oil is very low in DHA, the most important of the Omega 3 fats.
2. The Level Of Toxic Contamination In Each.
One of the perceived differences between fish oil and Krill oil is that the latter is less contaminated than the former. This however is not necessarily the case.
Airborne contamination can affect all parts of the globe. Scientists have found man-made pollution even in the North Atlantic and the Antarctic, including in creatures which inhabit the Antarctic such as penguins. Airborne pollution is found everywhere.
Establishing the cleanliness of the supplements that you buy is essential. Nowadays, sad to say, all forms of Omega 3 oils are likely to demonstrate some degree of contamination. The days are gone when it is possible to source marine oils high in DHA and EPA that are completely contamination free. This includes Krill oil.
However it’s quite possible to buy completely clean fish oil supplements. This is not because they are totally clean to begin with but it is because they have undergone rigorous decontamination processes, and the results have been checked by independent laboratory analysis. Before buying any Omega 3 supplements you should always check the certificate of analysis of the oil, which should always be made available to the public on the website.
Many people are unaware that Krill oil undergoes no decontamination process. It is therefore untrue to say that Krill oil is free from contamination.
3. Scientific Evidence Showing The Effectiveness Of The Supplements.
There have been literally thousands of studies which have demonstrated the effectiveness of the DHA and EPA Omega 3 fats in improving your health. However although there are claims by the manufacturers that Krill oil is tremendously effective in improving your health there are very few, if any, independent scientific studies that show that Krill oil is any better to your health compared to fish oil. The benefits of the Omega 3 fats in one will be the same benefits as found in the same quantity of Omega3 fats in the other.
Most of the studies that do exist are in fact financed by people with a financial interest in selling Krill oil. One Canadian company owns the patent on Krill oil and finances the studies, of which there are very few.
4. The Presence Of Astaxanthin In Krill Oil.
It is said that Astaxanthin is a powerful antioxidant with significant health benefits, and that Astaxanthin is found in Krill. Whilst this is true it is also true that some high quality fish oil supplements contain Astaxanthin at a significantly higher proportion that is found in Krill oil.
The anti-oxidant potency of Krill oil is in fact lower than that of the best fish oil supplements.
5. The DHA And EPA Are Attached To Phospholipids.
This is one more reason why it is claimed that Krill oil is more potent than fish oil. Without going into all of the scientific mumbo-jumbo about what this means, the bottom line is that there is no scientific evidence that this does anything at all, and there is no more evidence that the phospholipid structure in Krill oil offers any health benefits.
Ultimately Krill oil is about marketing. The health benefits of Omega 3 supplementation are established by many many scientific studies, and the benefit of fish oil to your health is recognized by such eminent authorities as the American Heart Association.
However, whilst Krill oil supplements are cleverly marketed, there is no independent scientific evidence to suggest that they are any more beneficial to your health than high quality Omega 3 fish oil supplements, they are dramatically more expensive for the same amount of active ingredient, and because they are not subject to any decontamination process the contamination level of Krill oil supplements may be extremely high. Nobody knows.
So if you’re convinced of the health benefits of DHA and EPA supplementation, and if you’ve been wondering about fish oil vs Krill oil debate, then rest assured that buying fish oil supplements will be cheaper, safer, and better for your health.
NOTE: More recently we have noticed an issue crop up with krill oil capsules that we had never thought of before.
There are some suggestions that krill can contain very small amounts of shellfish. This may be because they eat it, we have no idea. However we have read the suggestion that this may be an issue for people who have a shellfish allergy. To read a little more about krill allergens, albeit in scientific language, click here.
We haven’t seen any solid evidence in support of this suggestion, but thought we’d mention it anyway. Perhaps it’s being studied somewhere, we don’t know. To find clean quality fish oil supplements click here.To find out more about Peter Click Here
