Plenty of people seem to be confused because they’re both sources of Omega-3 fatty acid awesomeness. I’ll now explain the difference between krill oil vs fish oil.
But, just like other things, they have various qualities on which I will explain.
Just about the most vital in favour of fish oil, is that it’s significantly less expensive than krill oil. But, krill oil is much more effective, albeit a bit more costly, but its high strength outweighs its price drawback.
But when money is tight, fish oil or just quality foods with natural levels of Omega-3 (fish, pastured eggs, etc.) are the way to go.
The primary difference between the 2 is how the Omega 3 fatty acids are bound to the compounds of the oil. In fish oil, they come in the form of triglycerides (fat), but in krill oil they are bound to phospholipids (mainly phosphatidylcholine).
Phospholipids form the “lipid bilayer” which the cell membranes in the body are constructed with. If you do not understand how that works, then you should check out this cool video illustration showing something that is fundamental to life as we know it.
This one reason alone might be the reason on why Omega-3s in krill oil is a lot better than Omega-3s present in fish oil.
At present, there’re only a few tests regarding the comparison of krill oil against fish oil, but here are some tests that I found.
In one of them, krill oil provided a lot more benefits for ladies with premenstrual syndrome or pms and dysmenorrhea.
In another, krill oil had a much bigger effect on hyperlipidemia than fish oil, that is decreased total and Cholestrerol levels, triglycerides and raised HDL a lot more.
With these 2 tests, it appears that krill oil is a better source of Omega-3s. Read on to find out more about the benefits of krill oil.
Krill oil has an antioxidant known as Astaxanthin, which is an excellent source of health nutrients. This Astaxanthin anti-oxidant will be discussed on another post later.
Fish oil, in comparison, contains high amounts of Vitamin D and A. This might be significant for people who get little of these vitamins from food (or very little D from the sun).
Most people complain about the horrible after taste and “fishy burps” they feel after they take fish oil. This is much less commonly observed with krill oil.
I often swallow a tablespoon of cod liver oil every morning (caps are for wussies, I said) but now that I moved to krill oil capsules I do not think I’ll be going back to that. Yuck.
Krill oil is less likely to go rancid due to the high anti-oxidant content. Compared to fish oil, it has forty eight times the number of antioxidants, as calculated by the ORAC value.
Sadly, because of some people polluting some parts of the oceans, creatures in the ocean, including fishes have been toxified by pollution.
The animals which are on top of the food chain will eat all other animals below them, and this way, the toxins gather on the biggest fish (that is, incidentally, the largest suppliers of fish oil).
Krill is far below on the sea’s food chain, even lower than fish; this means that it has less contaminants in comparison to fish.
The amount of contaminants in fish oil will vary significantly between brands, thus please do not panic after reading this. Even if they contain an extremely little amount of pollution, the health benefits will still much outweigh the unwanted effects.
I have recently switched to krill oil. It’s a little bit more expensive, but you get what you pay for.
