Krill Oil Vs. Fish Oil: 5 Reasons Why Krill Oil Is Better

For years, the recommended supplement for Omega-3 fatty acids was Fish Oil, and for good reason. Fish oil contains Omega-3’s, which contain a litany of proven health benefits, including heart health, brain health, immune system support, joint function, and can also help with inflammation. However, Krill Oil has recently made a strong statement, in terms of being a better option for the essential and recommended Omega-3 fatty acids, we all need in our daily diet.

Both krill oil and fish oil contain essential Omega-3 fatty acids (EPA) eicosapentaenoic acid and (DHA) docosahexaenoic acid. Essential, meaning that your body cannot produce them on its own, therefore they must be obtained through your diet or through supplementation. So which is better, Krill Oil or Fish Oil?

What Is Krill Oil?

Krill Oil is derived from tiny shrimp-like crustaceans that reside at the bottom of the oceanic food chain in the Antartic Ocean. Krill feed off of phytoplankton and zooplankton, which are incredibly abundant in micronutrients. Because Krill live on such a nutrient-rich and sustainable diet, they are an incredible source of Omega-3's and antioxidants. 

What Is Fish Oil?

Fish oil is a general health supplement that is created from cold water oily fish such as salmon, herring, mackerel, anchovies, and sardines. Fish oil is rich in the Omega-3 fatty acids, DHA and EPA, which can also be found in foods such as flax and walnuts. Through several clinical studies, fish oil has been proven to help cardiovascular function, immune system health, brain health, and inflammation.

However, despite the impressive clinical evidence that supports the amazing health benefits associated with fish oil, there are a few key differences why Krill Oil proves to be better than fish oil. 

Why Is Krill Oil Better Than Fish Oil?

1. Krill Oil Has Better Bioavailability Than Fish Oil

One of the key differences between krill oil and fish oil is the bioavailability, or how quickly your body can absorb it. The Omega-3s found in krill oil are packaged as phospholipids, (the same structure found in your cellular membranes) which can be utilized immediately by your body. The Omega 3’s found in fish oil, however, are bound in triglycerides, which have to undergo additional conditions and processes in order for them to become bioavailable1

Krill oil has been shown to be absorbed 68% better than fish oil2 thereby suggesting that the Omega-3 polyunsaturated fats in Krill Oil are more bioavailable than Fish Oil.3

Since Krill oil is bound in phospholipids and not triglycerides, the addition of the phosphate group permits more efficient digestion and absorption. Krill oil is absorbed in 2-3 hours as compared to fish oil, which can take anywhere from 48-72 hours, therefore prolonging the benefits associated with inflammation and workout recovery.

2. Krill Oil Contains Astaxanthin

One of the many reasons Krill Oil is better than Fish Oil, is because it contains the world's most powerful antioxidant Astaxanthin. Astaxanthin is a carotenoid or an antioxidant which helps fight the build-up of free radicals and suppress the signs of aging. Free radicals are uncharged molecules having an unpaired valence electron that can cause damage to your immune system, as a by-product from numerous cellular reactions. Astaxanthin also plays a crucial role in reducing inflammation of the cardiovascular system and improving immune system function by increasing HDL-cholesterol which helps the body rid of plaque build up on the arterial walls.

3. Krill Oil Reduces Joint Pain & Inflammation 

The anti-inflammatory effects of Astaxanthin can help reduce chronic inflammation of the tendons and joints, which can cause detrimental effects to your training and recovery. In a randomized, double-blind placebo-controlled trial by the Journal of the American College of Nutrition, 90 patients were recruited with rheumatoid and or osteoarthritis to evaluate the effectiveness of krill oil on arthritic symptoms. The results were astounding. After seven days of treatment with a dose of 300mg of administered krill oil, patients reported reduced pain scores by 28.9%, reduced stiffness by 20.3%, and reduced functional impairment by 22.8%.5

4. Krill Oil Is Safer Than Fish Oil 

Norway is the worlds leading nation in fish oil manufacturing, making up nearly 40% of the worlds fish oil market. A recent Norwegian study showed that 95% of 113 over the counter fish oil capsules were so rancid, that they didn’t even meet official quality standards. 8 The oxidative stability of fish oil, when tested at a storage temperature of 20 and 40˚C showed that the Omega-3 content was highly influenced.7 In another study, 171 North American Fish Oil brands were analyzed for oxidation safety and 50% exceeded the voluntary recommended levels for markers of oxidation.9

5. Krill Oil Is Better For The Environment Than Fish Oil

If you care about the environment and the preservation of the beautiful world we live in, krill oil is the responsible and sustainable choice to make when choosing an Omega-3 supplement. Why? Krill are tiny shrimp-like crustacean that measure between a minuscule 1-6cm in length and which are found in the deep, clean waters of the Antarctic Ocean, which feed primarily on phytoplankton and zooplankton. Because of their short lifespan, krill simply don’t accumulate heavy metals, pesticides and other toxins as compared to fish oil. In 2008, the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) set a precautionary catch limit of 5.6-million tons of krill. However the annual catch only measures 0.3% of the unexploited biomass of krill. Therefore, harvesting krill for krill oil production, won’t interfere with the long-term marine ecosystem.

So Which Is Better, Krill Oil Or Fish Oil?

Fish Oil, has been the preferred method for Omega-3 supplementation for years. However, overwhelming evidence proves that Krill Oil and it's powerful antioxidant Astaxanthin have even greater health benefits, especially for post-workout recovery, due to the bioavailability and inflammation response. Do yourself a favor and replace the four pills of fish oil you take a day with one 500mg capsule of Krill Oil. It will provide you with better results and better overall health. Not to mention, you can finally ditch the fish burps.
