A lot of people seem to be confused since they’re both sources of Omega-3 fatty acid awesomeness. I’ll now explain the main difference between fish oil or krill oil.
However, they do differ in several crucial ways that I’ll explain here.
With regard to price, fish oil is less expensive of the two. But, krill oil is a lot more strong, albeit a little more expensive, but its high potency outweighs its price disadvantage.
But when money is tight, fish oil or simply quality foods with natural levels of Omega-3 (fish, pastured eggs, etc.) are the best option.
The real difference between the 2 is how the Omega-3 fatty acids are bound to the molecules of the oil. In fish oil, they are available in the form of triglycerides (fat), but in krill oil they are bound to phospholipids (primarily phosphatidylcholine).
Phospholipids are what forms the double layer, which in turn makes up the cell membranes of our body. If you don’t understand how that works, then you should look at this cool video illustration showing something that is fundamental to life as we know it.
This might be the reason the Omega 3s in Krill oil are better absorbed/more potent than those in fish oil.
Presently, there are only some 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 females with premenstrual syndrome and dysmenorrhea.
Another test shows which krill oil makes a bigger effect on the hyperlipidemia compared to fish oil, as it reduces Cholesterol levels and raises HDL cholesterol.
With these 2 tests, it seems that krill oil is a much better source of Omega-3s. Read on to learn more about the benefits of krill oil.
Krill oil has an antioxidant known as Astaxanthin, which is a fantastic source of health nutrients. I’ll discuss this anti-oxidant in another post very soon.
A lot of types of fish oil do contain useful amounts of Vitamin A and D. This may be vital for people who get little of these natural vitamins from food (or very little D from the sun).
Lots of people complain about nasty after taste and “fishy burps” after taking fish oil. This is, however, only a common incidence among those who take fish oil instead of krill oil.
I often swallow a tablespoon of cod liver oil every morning (caps are for wussies, I said) but now that I switched to krill oil capsules I do not think I will be going back to that. It tastes bad, in fact.
Krill oil is less likely to go rancid because of the high antioxidant content. Actually, the anti-oxidant power of krill oil is 48 times stronger compared to fish oil, measured by the ORAC value.
But, if you desire to ensure that if your krill / fish oil has gone rancid, you may take a bite at among the gel caps. If it tastes slightly unpleasant, then it still ordinary and it hasn’t yet gone rancid. If they taste all nasty and rotten, throw them away.
Unfortunately, because of some people polluting certain parts of the oceans, creatures in the ocean, like fishes have been toxified by pollution.
The animals which are on top of the food chain will eat other animals below them, and this way, the harmful toxins gather on the biggest fish (that is, incidentally, the biggest suppliers of fish oil).
Krill is much below on the ocean’s food chain, even below fish; this means that it contains less pollutants in comparison with fish.
Different brands of fish oil will have different amounts of toxins, but this shouldn’t freak you out. While they may have a lot more contaminants in comparison to krill oil, its (fish oil) health benefits still outweighs the unwanted effects.
Krill oil is certainly a superior form of Omega 3 compared to fish oil (that is something I’ve been taking consistently for years).
I have recently moved to krill oil. It is a little bit more expensive, but you get what you pay for.
