Natural Biology highly suggest you consider taking both. Take 1 Norwegian Omega 3 daily with 1 Arctic Ocean Krill Oil. The combination offers you the the best alternative of both worlds - and both worlds have strengths the other one does not offer. Natural Biology Omega 3 supplements are pure, at full strength, and are not diluted. Often companies dilute omega 3 krill oils and fish oils to reduce the fishy smell - and some to increase profits. Your krill oil and a good fish oil should have a modest fishy smell but the odor if real fishy means the product is rancid or not fresh. If so, do not take.
Why Krill Oil May Be a Better Choice Than Fish Oil According to Dr. Oz
Many experts, including Dr. Mehmet Oz, cardiothoracic surgeon, author, talk show host, and commentator for "The Dr. Oz Show", have made the switch from fish oil to krill oil, as research suggests it is the superior choice for high-quality, animal-based omega-3 fats.
We however do not believe Dr. Oz has evaluated Norwegian Omega 3 yet? We obviously cannot comment for him, but based on research we are confident most physicians and scientist would agree to its merit.
The primary drawback with fish oil is its susceptibility to oxidation (rancidity), which can occur at any point during the processing, or after you open the bottle. This process was taken care dutifully with the processing of Norwegian Omega 3. Processing is actually accomplished on-board the ship in a state-of-the-art facility. Nothing compares. Omega-3 fats are extremely fragile and are prone to be damaged by oxygen, which can radically reduce their health benefits and even make them damaging to your body.
Aside from the astaxanthin, krill oil offers other benefits over fish oil as well.
Two studies illustrated the superior benefits of krill oil over fish oil.
• The first study, published in January, found that the metabolic effects of the two oils are "essentially similar," but that krill oil is as effective as fish oil despite the fact that it contains less EPA and DHA.
• This finding corresponds with unpublished data suggesting that krill oil is absorbed up to 10 to 15 times as well as fish oil, which would explain this discrepancy.
But what makes it that much more absorbable? In a nutshell, it has to do with its molecular composition.
Fish oil is in a triglyceride molecule that has to be broken down in your gut to its base fatty acids of DHA and EPA. About 80% to 85% is never absorbed and is eliminated in your intestine (this is why fish oil can cause you to experience burp back, and why about half of all people cannot tolerate fish oil). Then, once the fatty acids are absorbed into your bloodstream, your liver has to attach it to phoshphatidyl choline for it to be used by your body.
The amazing beauty of krill is that it is already in the correct, phosphatidyl choline-bound form in the capsule, so your body uses virtually 100% of it.
Unlike fish oil it contains 69 different phospholipids, 9 of which are omega-3 fatty acid bound. Phospholipids can act as emulsifiers, enabling oils to form a colloid with water, basically enhancing the absorption and transport of the fats to which they are bound.
According to an article in Functional Nutrition, krill oil typically provides 14% EPA and DHA, along with 0.2% naturally occurring astaxanthin. Fish oil typically provides 30% EPA and DHA. At first glance, it may appear as though fish oil is better simply because it contains a higher ratio of omega-3 fats.
