Fish Oil Vs.Krill Oil

Why Omega-3 from Krill Oil is Superior

Most people know about fish oil but far less have actually heard about krill oil or know what the difference is. In this article we will explain what makes krill oil the superior source choice for your important Omega-3 fatty acids.

Krill oil is rich in antioxidants, meaning it will not become rancid inside your body and that will not lead to free radical formation in your body. The most powerful antioxidant found in nature is a carotenoid called Astaxanthin and is found naturally in krill oil. A unique marine-source flavonoid that bonds with EPA and DHA, making them a much more bioavailable source.

The source

Fish oil is extracted from oily cold water fish, wild caught fish such as halibut, herring, mackerel, sardines, cod, albacore tuna or farmed fish such as salmon.However, most fish oil supplements on the market contain oils from more than one fish source.

Krill oil comes from a small crustacean and shrimp looking creature that lives in the pristine waters  around the Antarctic. The feed solely on plankton that floats on the ocean surface and are at the very bottom of the food chain.

What's the nutritional content?

Fish oil is made up of about 30% of the important EPA and DHA Omega-3 fatty acids. EPA and DHA in fish oil are packaged as triglycerides and have to undergo additional processing in the body in order to make them bioavailable. Furthermore, fish oil is highly perishable compared to krill oil because it lacks natural preservatives and turns rancid inside your body.

Krill contain 14% of EPA and DHA. Krill oil is a superior source of EPA and DHA because the polyunsaturated fats are packaged as phospholipids, which can be used immediately by your body without the need of conversion. This makes krill oil up to 48x more potent than fish oil and makes it a much better source for omega-3. As krill oil naturally contains astaxanthin, the most powerful natural antioxidant, it helps to keep krill oil stable for much longer compared to fish oil.

What is the most sustainable source of Omega-3?

Large scale fishing since the 1950's has seen a 90% reduction of large fish species in our oceans. Fish caught for consumption by humans and used for fish oil are currently being fished out. Scientist believe that we are over-fishing our oceans annually by up to 35% of what is sustainable. This has been especially devastating for some local ecosystems in the pacific that have fishing quotas of 100% over the recommended sustainable limit. Species and populations of top predatory fish are disappearing at an alarming rate.

Krill are caught in the pristine waters around the Antarctic and the sustainability is strictly ensured by the international organisation; Commission for the Conservation of the Antarctic Marine Living Resources or CCAMLR for short. In 2002 CCAMLR set an annual limit of 6.6 million tons as a precautionary harvesting limit to ensure the sustainability of krill and the marine life that depends on krill. This is out of an estimated 740 million tons of krill that live in our waters, making krill the largest biomass on Earth. So far only 2% of the set limit has ever been harvested in a given year and scientists theories that the annual limit of 6.6 million tons could be safely increased 50x of today's levels without damaging the ecosystem.

What about contaminants - what is safest?

Most fish that are used in fish oil are at the top of the food chain. This means that fish oil is extracted from fish species that have accumulated high levels of contaminants by eating other fish that feed on other fish. Contaminants that are be found in fish are:

 Radioactive substances such as Strontium
 Toxic's such as Cadmium, Lead, Chromium and arsenic

So what about farmed fish? A large portion of fish oil supplements comes from farmed fish but they have actually been found to contain higher levels of heavy metals. In fact much higher levels than fish caught in our oceans and fish farming strains the local environment.

Krill oil comes from krill that are harvested in our most pristine waters around the Antarctic. Krill are also at the very bottom of the food chain so they do not accumulate heavy metals, PCB's, Dioxins and other contaminants making it the safer source of Omega-3. Each batch we create can be checked for exact harvested location. Please select the "Eco" tab at the top to see where your batch has been harvested.

What about the stability of the oils?

Fish oil is highly perishable compared to krill oil because it lacks a natural preservative. When fish oil turns rancid inside your body, it leads to free radical formation and damages cells. This is a major drawback of fish oil. Regardless of what format the fish oil is in, the high levels of the omega-3 fatty acids EPA and DHA, which are responsible for the health benefits of fish oil, are susceptible to oxidation*.

Fish oil should always resemble fish in its most pure and fresh state. Exposure to oxidation increases taste and fishy smell and is a clear indication of oxidation of the fish oil. Never buy Omega-3 in liquid form as it is highly exposed to oxidation. A test was recently conducted by ConsumerLab, who tested 35 products for freshness and purity and assessed whether or not these products contained the amounts of EPA and DHA claimed on their product labels. Out of the 35 products tests, 11 failed to pass testing.

Krill oil naturally contains natures most powerful antioxidant called Astaxanthin that is 800 times stronger than CoQ10 and 65 times more powerful than Vitamin C. Astaxanthin has many amazing health benefits and as an antioxidant it naturally protects krill oil from oxidation*. Learn more about the many health benefits of Astaxanthin by clicking here.


Let me give you an example that you can relate to from the kitchen. Cut apples or avocados and they are beautiful in their natural color but leave them on the kitchen table for a short while and they begin to turn brownish. This happens as the apples and avocados react to oxygen in the air. Continue to leave the apples or avocados and they end up brown and not looking very appealing to eat. There is a trick to slow them turning brown and that is simply to squeeze lime or lemon over them and the reason that they now turn brown much slower is the natural antioxidant you know as Vitamin C. Tests made comparing Vitamin C to Astaxanthin showed far longer protection with Astaxanthin.

When we first decided to add an omega-3 supplement we were all sure that it was going to be a fish oil but the more studies we read and saw the evidence we knew it had to be from a better source in order to create a supplement that was of superior quality and ended up with our AntarcticRed Krill Oil supplement. We have worked with the best in the industry to create this state of the art supplement that is superior in quality. Learn more about our AntarcticRed Krill Oil by clicking here.

Fish oil and krill oil are both not recommended for some people, such as those with a shellfish or seafood allergy. Those who have a blood coagulation disorder or are taking blood thinners should also refrain from taking these supplements.
