Is Krill Oil Safe Krill Oil Benefits
1. Fights Inflammation
Acute inflammation is a normal immune response that can help protect your body against foreign invaders. Chronic inflammation, on the other hand, is thought to contribute to a range of health conditions, including obesity, diabetes, heart disease and even cancer.
Krill oil is high in omega-3 fatty acids like docosahexaenoic acid and eicosapentaenoic acid , which have been shown to have anti-inflammatory properties. According to one study out of the University of Tehran in Iran, supplementing with omega-3 fatty acids for just eight weeks was able to significantly reduce levels of inflammatory markers in the blood. Krill oil also contains astaxanthin, a natural pigment that can help fight the free radicals that cause chronic inflammation.
In addition to lowering the risk of chronic disease, the anti-inflammatory properties of krill oil could have far-reaching benefits that extend to nearly every aspect of health, from slowing aging to protecting against certain autoimmune conditions.
2. Improves Heart Health
Whether youre looking to drop your cholesterol levels or simply keep your heart in tip-top shape, krill oil may be able to help. Krill oil is jam-packed with omega-3 fatty acids, which have been linked to reduced inflammation, a decreased risk of heart disease and improvements in cardiovascular function.

How Much Omega 3 For Dogs With Allergies
Omega 3s are not only beneficial for humans, but for dogs as well. In fact, one study found that adding 1 tablespoon of flaxseed oil to a dogs diet can reduce allergies by 30%.
The recommended dose is 20 mg per pound EPA and DHA per day.
While this isnt necessarily a question about allergies specifically, omega 3s have been proven to be beneficial in combating other health problems such as cancer and arthritis.
It would make sense that these benefits might also extend to those who struggle with seasonal allergies as well since many allergic reactions are caused by inflammation in the body.
Are Krill Oil Benefits Even Better Than Fish Oil Benefits
Looking to shed a few pounds, improve your skin or keep your brain sharp? You may want to consider taking krill oil. High in both omega-3 fatty acids and antioxidants, the potential krill oil benefits are pretty impressive.
While I dont personally consume krill oil, which comes from shellfish, as I follow a biblical diet, it has gained widespread popularity in recent years as a safe and healthy alternative to fish oil. The benefits of krill oil vs. fish oil are nearly identical, but krill oil is more bioavailable, more sustainable, and less likely to be contaminated by mercury or heavy metals.
So what is krill oil made from, how can it affect your health and should you be adding it to your daily routine? Lets take a look.

What Is Krill Oil
While the word krill means small fish in Norwegian, the tiny crustaceans pack a big punch with their sources of docosahexaenoic acid and eicosapentaenoic acid , two omega-3 fatty acids only found in marine life.
Research has shown that these omega-3 fatty acids may benefit heart health, as well as inflammation, says Ilic.
What Is The Best Vegetarian Alternative To Krill Oil
So even though krill oil is slowly rising in popularity versus the classic fish oil option, it still comes with its own health, ethical, and environmental concerns. The problem is especially pertinent for vegetarians who need a reliable omega-3 source.
Omega-3s can be found in numerous plant-based foods, including walnuts, chia seeds, and flax seeds. Unfortunately, the omega-3s that are prevalent in most plant-based foods are alpha-linolenic acids . While still an essential nutrient, ALA needs to be converted into DHA and EPA in your body in order to be used for any health benefits. The conversion process has a notoriously low yield, which means that you would have to eat an extraordinary amount of ALA-rich fare to reap any health benefits.
The best way for vegetarians to get their necessary omega-3s would be to get their EPA and DHA directly, but fish oil and krill oil are not suitable.
So what is the best vegetarian alternative for krill oil? All signs point to a revolutionary new solution: algae oil supplements.

Fish Oil Is Cheaper And More Accessible
One advantage that fish oil may have over krill oil is that its typically much cheaper and more accessible.
While krill oil may share and even exceed many of fish oils health benefits, it comes at a higher cost. Because of expensive harvesting and processing methods, krill oil can often be as much as 10 times more expensive than fish oil.
However, fish oil isnt just cheaper. It is also often much more accessible.
Depending on where you live and shop, you may have a harder time finding krill oil supplements, and youll likely find less of a selection than fish oil.
Epa And Dha Absorption
A notable distinction is that krill oil has a different structure in EPA and DHA contents compared to fish oil. This is because the fatty acids in omega-3s are triglycerides, while those in krill oil are phospholipids. Due to the structural changes, our bodies will process krill oil in a different way. Predominantly, we will absorb higher quantities of EPA and DHA in krill oil than we do with fish oil.
There are studies that analyze the fatty acids in the blood after consuming krill oil and fish oil separately. During the first three days of post-intake, it was reported that more EPA and DHA had been found in the participants who took krill oil. Those who consumed omega-3 fish oil experienced lower proportions of the same fatty acids.

One of the notable benefits of using Krill oil for dogs is its effectiveness in relieving chronic pain from injuries occurring from an attack.
It can also help to repair and restore your pets skin coat to make it look much great. For those who have tried other aids for their dogs cognitive impairment, they find this oil quite fabulous by far.
Most people have reported the successful use of this product to treat their dogs scraggy and dry skin after an attack. It does not leave behind any fishy breath in your dog besides being easy to store and apply.
What Evidence Is There For The Beneficial Effects Of Omega
Although experts agree food sources rich in omega-3s are vital to maintain healthy body function, few studies have confirmed any benefits for additional dietary intake or supplementation.
A Cochrane review stated it was unclear whether omega-3 fatty acids changed the risk of death, heart attack, stroke, or cancer in people with or without pre-existing cardiovascular disease.10
No convincing evidence was found for omega-3 supplementation in the prevention of cognitive decline and the treatment of mild to moderate Alzheimers Disease.11,12
In intermittent claudication a Cochrane review found no evidence of a consistent benefit for omega-3 fatty acids. Supplements were also more likely to cause diarrhea, nausea, or flatulence.13
For cystic fibrosis, supplements may provide some benefits however, the results were not significant enough to recommend routine supplementation.14
For type-2 diabetes, no effect on blood glucose control or fasting insulin was noted for omega-3 fatty acid supplementation, although some triglyceride lowering was noted .15
For many other disorders such as ADHD, bipolar, Crohns disease or Multiple Sclerosis there appears to be little benefit for omega-3 supplementation.16,17,18,19
Are There Risks With Krill Oil
Less research has been performed on krill oil and although no side effects have been reported, the safe maximum dose of natural astaxanthin has not been determined.
Krill make up a vital part of the Antarctic food chain and a huge number of species higher up the food chain depend on them. Fishing krill has the potential to catastrophically destabilize this important food chain. Therefore, fish oils are more sustainable than krill oil.
Are There Any Side Effects
Fish oil is usually well tolerated. A possible side effect from fish oil supplements is a mildly upset stomach . There is currently no evidence that fish oils increase the risk of bleeding or interact with medicines that affect bleeding, such as aspirin or warfarin. Despite this, it is recommended that you consult with your doctor before having major surgery or if you are commencing fish oil while taking warfarin. INR monitoring tests may be done more often at first, as with the addition of any new treatment, to ensure there are no side effects. If there is any bleeding, stop taking fish oils and consult with your doctor.

Krill Oil Vs Fish Oil: Krill Oil Has Better Bioavailability
One of the key differences between krill oil vs. fish oil is the bioavailability, or how quickly your body can absorb it. The Omega-3s found in krill oil are packaged as phospholipids, which can be utilized immediately by your body. The Omega 3s found in fish oil, however, are bound in triglycerides, which have to undergo additional conditions and processes in order for them to become bioavailable
Krill oil has been shown to be absorbed 68% better than fish oil thereby suggesting that the Omega-3 polyunsaturated fats in Krill Oil are more bioavailable than Fish Oil
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

Krill Oil Vs Fish Oil: Is Krill Oil Really Better Than Fish Oil
For years, the recommended supplement for Omega-3 fatty acids was Fish Oil, and for good reason. Fish oil contains Omega-3s, 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 Eicosapentaenoic acid and 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 is Krill Oil really better than Fish Oil?

May Promote Cardiovascular Health
Krill oil contains essential omega-3 fatty acids that may promote cardiovascular health. The oil was found to decrease total cholesterol levels and increase HDL cholesterol. A high dose of krill oil was also shown to decrease triglyceride levels in the blood . However, the cardiovascular benefits of krill oil remain unproven and need further research. Another study suggests that this oil may reduce the risk of cardiovascular disease, specifically endothelial dysfunction, in patients with type 2 diabetes .
As stated, krill oil may help lower total and LDL cholesterol levels. According to a study, this oil may effectively manage hyperlipidemia by reducing total cholesterol, LDL, and triglyceride levels, and increasing HDL levels. In fact, krill oil was found to be more effective than fish oil in lowering glucose, triglyceride, and LDL levels .
However, the cardiovascular benefits of krill oil need further research.
What Are The Risks Of Taking Krill Oil
- Side effects. Krill oil seems to cause few side effects. Some people might have gas, bloating, or diarrhea.
- Risks. Check with a doctor before using krill oil if you have a bleeding disorder or a seafood allergy. Krill oil can slow blood clotting, and shouldnt be taken for two weeks before surgery. If you are pregnant or nursing, talk to your health care provider before taking krill oil.
- Interactions. If you take any medicines regularly, talk to your doctor before you start using krill oil supplements. Like other omega-3 fatty acids, krill oil may cause increased risk of bleeding and should be used with caution, especially if you are taking anticoagulant medications . Since krill oil interferes with the blood‘s ability to clot, it could interact with medicines such as blood thinners and anti-platelet drugs. The same risks might apply to taking krill oil while using supplements such as ginkgo biloba, garlic, and ginger. Its absorption may also be affected by certain weight loss drugs. Krill oil may lower blood glucose levels, so talk to your doctor before using if you take any medicines for diabetes.

Krill Oil Vs Fish Oil: Real World Comparison
Lets compare MegaRed to a Ultra-concentrated Fish Oil.
MegaRed contains 90 mg of Omega-3 per pill.
No, that was not a typo.
It contains only 90 mg of Omega-3 per pill. And its the Omega-3 in the krill oil that gives you the actual health benefit.*
There are a few good fish oil pills that provide 900 mg of Omega-3 in just one pill. Or 10X more Omega-3 per pill.
Lets compare it with GNCs Triple Strength Fish Oil with 900 mg of Omega-3 per pill.
It costs $26 for 60 pills. Or $0.43 per pill. Almost exactly the same as a MegaRed pill.
MegaRed = 90 mgTriple Strength Fish Oil = 900 mg
But Krill oil is only 40% better absorbed. For the price, shouldnt krill oil be 1000% better absorbed?
Forget Triple Strength Fish Oil how about cheap, old fish oil from Walmart? Even that has 300 mg Omega-3.
Krill oil would have to be 300% better absorbed than REGULAR fish oil to equal the discount fish oil at Walmart, let alone ultra-concentrated or Triple Strength fish oil!
But it is only 40% better.
Why Are Omega Fatty Acids So Important
Omega-3 and -6 fatty acids have an important structural role needed for cell membranes. They are also energy sources and are used to form signaling molecules called eicosanoids, comprised of prostaglandins, thromboxanes, and leukotrienes.
There are many different prostaglandins with wide-ranging roles, such as the sensation of pain, inflammation, regulation of pregnancy and birth, control of blood pressure, secretion of stomach acid, contraction, and relaxation of smooth muscle.
Thromboxanes regulate blood clotting by causing constriction of blood vessels and the aggregation of platelets , which are early steps in blood clotting.
Leukotrienes are involved in immune function by attracting immune cells such as neutrophils to sites of inflammation. They also constrict bronchioles in the lungs and make capillary walls permeable.
This is thought to be because the metabolic products of omega-3 fatty acids are less inflammatory than those produced from omega 6 fatty acids. Western diets are associated with an imbalance of omega-3, -6 such that instead of levels of omega 3 being higher than 6, the reverse is more commonly seen. This is associated with an increased risk of chronic inflammation.
There are three types of omega-3: those found in oily fish called EPA and DHA and the plant-based ALA.
Dietary Supplementation With Krill Oil Reduces Hind Paw Thickness In Mice
The extent of hind paw swelling was assessed using a dial caliper .1B). Hind paw swelling was significantly lower in krill oil supplemented mice at day 54, 60, 62 and 66, compared to control mice. Paw thickness in mice administered fish oil was different from control animals at day 49 and 54. In all groups, the main increase in hind paw swelling occurred after day 58.
Krill Oil Vs Fish Oil: Which Is Better
When it comes to taking an Omega 3 supplement, some people swear by the health benefits of krill oil.
Others stand firm with fish oil. In fact, these two fishy oils are a cause of great controversy, with debates raging across the web as to which is the superior source of Omega 3.
Despite multiple debates, the jury is still out, and the questions remain which is indeed betterkrill oil vs fish oil?
