The introduction of Krill Oil into the market as a source of omega-3 was not taken seriously at the beginning. It was considered as a trend that would soon come to pass. This is because it was argued that the oil contained polyunsaturated fatty acids (PUFAs), which was not good for the health. It was also argued that this oil had low levels of EPA and DHA -100-150mg- that would not make much difference in the health of an individual, at least in the same way that high concentrations of omega 3 would.
What Are Krill?
Krill look like shrimps. They have a reddish body that is transparent and big eyes that are black. They can be found in oceans anywhere in the world.
Krill are eaten by most sea creatures, such as whales, fish, squid, penguins, and seals. They are a large part of the earth’s biomass.
These fish feed on phytoplankton. They can be found swimming in swarms.
There are over 85 species of krill. However, the OCEANO3 Krill Oil is derived from the Antarctic Krill. This fish is found in the Southern Antarctic Ocean.
What is Krill Oil?
Krill oil is extracted from krill, which is a shrimp-like creature. The specific species of shrimp that is commonly used is known as the Antarctic krill (Euphausia superb), and it can be found in the Antarctic Ocean. The good thing about this ocean is that the water has not been polluted.
The great news is that krill is available in plenty. There is no shortage given that fishing is highly controlled. CCAMLR regularly reviews the amount of fish that people are allowed to harvest.
Krill oil provides so many health benefits. It is rich in Omega 3 fatty acid and has live EPA and DHA levels. These two elements are important in the functioning of the human body. They help in proper functioning of the brain, heart, joints, nervous system, plus they help in minimizing inflammation in the body.
Krill oil is a new source of omega 3. As a result of this, there is a still lot of debate about its use and how it compares to fish oil.
Krill Oil vs. Fish Oil
Both fish oil and krill oil are good sources of omega 3 fatty acids. However, the two oils are not the same; their molecular properties differ. The omega 3 in the fish oil is connected to triglycerides, while the major part of the omega 3 in krill oil are attached to phospholipids, while a few others are connected to triglycerides.
As a result of this, it means that these two oils behave differently in the human body. The thing about phospholipids is that they do not combine well with water, while triglycerides do mix well with water. Phospholipids are better absorbed by the body as compared to triglycerides, so krill oil is better absorbed by the body as compared to krill oil.
Astaxanthin is an antioxidant that is found in krill oil. It is what gives this oil its characteristic dark red color.
Since astaxanthin is an antioxidant, it helps in the repair of inflamed of cells that have been damaged by free radicals. Astaxanthin falls under carotenoids. It has been proved to be one of the most powerful antioxidants, and it is much better than vitamin E, lutein, and beta-carotene.
Fish oil does not have any natural antioxidants; the antioxidants that it has - vitamin E tocopherols - are those that have been added by the manufacturer. The manufacturers add the antioxidants to prevent the oil from going rancid since the omega 3 oils tend to get lipid peroxidation and go bad fast.
Which One Should You Choose?
The decision that you make will be based on what your personal preferences are. Generally, there is no big benefit of choosing krill oil over fish oil supplements. As much as krill oil is better absorbed by the body, krill oil supplements tend to have lower amounts of omega 3 fatty acids as compared to fish oil supplements.
There are two major kinds of fish oil supplements. This includes ultra-strength and ordinary strength. The ultra-strength supplements are usually highly concentrated and have lots of omega grams for each capsule or teaspoon. This is usually much higher than what is contained in krill oil supplements.
The other thing about fish oil is that extensive research has been done on it. Therefore, there is lots of information about this product and its health benefits. Also, the correct daily dose of oil has been established based on the kind of condition that you have. However, because krill oil is absorbed differently by the body, we cannot simply transfer the research that has been done on fish oil onto krill oil.
There is also the issue of toxicity. Ideally, the fish harvested from the Antarctic should not have been polluted. But this is not always the case. There have been cases where products made out of krill that have been harvested from the Antarctic have been found to have some level of toxicity. However, the FDA has declared that krill and all products that have been derived from it have been found to pass GRAS (generally recognized as safe) standards.
It has also been found that fish oil tends to have traces of heavy metals, toxins, mercury and other contaminants. This is more so if they have been harvested from contaminated waters.
That is why it is essential that you buy your fish oil from a trustworthy manufacturer. The manufacturer must be adhering to the safety standards that have been set by fish oil safety organizations, such as the Council for Responsible Nutrition (CRN), European Pharmacopoeia, IFOS, and the Global Organization for EPA and DHA Omega–3 (GOED).
Can You Combine Fish Oil with Krill Oil?
It is quite easy to find fish oil. You can buy it from most pharmacies or grocery stores, as they tend to have many products to choose from. Fish oil has high levels of omega 3 fatty acids. Whether you get omega 3 from supplements or fresh fish oil, there are so many benefits to consuming this product. Omega 3 is good for your brain, heart, blood pressure and circulatory system. Once you start taking omega 3, it will help to minimize the bad cholesterol in your body, while increasing good cholesterol shortly after you start taking it on a regular basis.
How can you tell that you are purchasing superior quality products? When buying fish oil, you must always be careful. This is because if the fish has been sourced from impure sources, it will affect the quality of oil that has been produced. In fact, oil that has been made from fish that have been sourced from manmade ponds tend to have a lower concentration of essential nutrients. In fact, there are some products that have been recalled over the years for failing to meet PCB standards when it comes to mercury contamination and other contaminants. Take a look at the label of the product to determine how good it is. Also, the longer the product sits unused on the shelf, the more its quality will go down, especially when it is exposed to sunlight, air, and heat. That means that you will be taking huge pills that give you a fishy burp for absolutely no gain at all.
You don’t have to take krill oil and fish oil simultaneously.
Krill oil produces a higher quality of omega 3 oils as compared to fish oil. The National Library of Medicine–National Institute for Health states that an adult should take 1-4g of omega 3 fatty acids on a daily basis, based on how much the person weighs. Viva Natural’s Krill Oil contains 300mg of omega 3 oils in each of its servings.
Krill oil also has high levels of astaxanthin. This is a powerful antioxidant that helps to protect the body from radical free cells that are thought to be some of the major causes of cancer and neurodegenerative illnesses, inflammation in the body and cell degradation. Astaxanthin works by neutralizing the free radicals in the body. It does this by giving out electrons to any unpaired electrons, or it can also abstract an unpaired electron.
According to the Alternative Medicine Review, consistently consuming astaxanthin of as low as 1mg a day on a regular basis over a 4-week period can result in significantly high levels of astaxanthin in the blood. This antioxidant is red. This color is derived from the reddish color of the algae that the fish feeds on. Viva Natural’s Krill Oil has high levels of astaxanthin that is as much as 54X the antioxidant level that is found in any fish oil product that is currently being sold. The krill oil that we sell has 1.6mg of astaxanthin for each serving.
Krill oil has phospholipids that are in a long chain form when it comes to structure. This is what makes them easily absorbed by the human body. This fast absorption into trillions of cells in the body is what makes the antioxidants quite powerful in fighting against free radicals in the body. On the other hand, fish oil must first be converted into the long chain form before it can then be absorbed into the body.
One major benefit that krill oil has over fish oil is that when you take it, you don’t get big fishy burps that you get when you take fish oil. This is something that a lot of people complain about and dislike about taking fish oil. This is because krill oil reduces the reflux action that causes such burps. Also, Viva Naturals Krill Oil has smaller pills than the ones that regular fish pills have. This makes them easy to take.
Viva Natural Krill Oil is derived from fish that are harvested in Antarctica. Considering that krill is lower on the food chain, it means that it is less likely to consume other fish or substances that might have mercury or toxins, rendering the products derived from krill oil as being relatively safe to consume. It is highly unlikely for the fish oil to go bad as it is being transported to the manufacturing plant considering that it is manufactured straight after the fish has been harvested. This means that the krill oil that you get has been shipped directly to you from the manufacturing plant, making it fresh and highly nutritious. There is no worry about the oil having been polluted by mercury, heavy metals and other pollutants that you can frequently find in fish sources. You will just need to take two of these pills on a daily basis, and you will have consumed enough antioxidant that is not found in fish oil. Some of the benefits that you will get by taking this oil include reduced chances of getting heart diseases, reduced blood pressure problems and reduced bad cholesterol levels, while your neurological health will get better. You can be sure that Viva Naturals Oil is free from toxins, PCB, and other contaminants. If you care about holistic health, then this is the product for you as it is made to the highest standards possible. Therefore, there is no need for you to take both fish oil and krill oil simultaneously, considering that krill oil has been made to a high standard.
Just by taking krill oil, you can be rest assured that you will get the required amount of omega 3 levels, plus you will get the benefit of getting antioxidants.
Krill Oil Components
Fat makes up 12-50% of this oil. However, in the spring the fat content tends to be lower. This is because there isn’t as much food in the spring for the fish. There is usually lots of food during summer months.
Omega 3 fatty acids make up 19% of the total amount of fat in the whole krill.
One of the things that the phospholipids in the fish do is to protect cells from getting damaged as a result of free radicals.
There are other acids that can be found in this fish. These include:
Antioxidants and Vitamins
Krill oil contains vitamin A, vitamin E, Vitamin B9 and vitamin B12. It also has choline. This is used to move fats around and helps to minimize homocysteine.
Moreover, krill oil has astaxanthin, which is a strong oxidant. It dissolves in fat. Though, the astaxanthin levels in krill might be too low to make any significant health benefits.
Mechanisms of Action
The Endocannabinoid System
Taking omega 3 helps the endocannabinoid system to work quite well. Endocannabinoids excite the immune system. It helps to improve memory, mood, and motivation. If you have a problem with your endocannabinoid system, it can affect how your heart functions, your weight, blood sugar, anxiety levels depression and your memory.
When experimented with on with rats, krill oil helped to lower the endocannabinoid levels, accumulated fat, and endocannabinoid receptor activity.
Keep in mind that reduced levels of endocannabinoid activity in the brain can be negative, but krill oil does not negatively affect the rational capacity of an individual.
Krill oil is an anti-inflammatory. The Omega 3s in it helps to reduce inflammatory cytokines IL-1β and TNF-α.
Misconceptions About Krill
One of the things that have been emphasized in the marketing of krill oil is its phospholipid structure as compared to that of triglycerides that are derived from fish oil. Even though this is true, it has been unduly emphasized, such that it has been blown out of proportion. This has led many people to ignore the dosage issue. A lot of users wrongly think that consuming low doses of EPA and DHA omega 3 that has been derived from krill oil is the same as consuming high doses of EPA and DHA from fish oil.
Research shows that higher doses of omega 3 fatty acids are needed in the body, especially when it comes to EPA levels than what most manufacturers recommend consumers to take. This is if you are to experience any significant impact on the state of your health. For instance, most manufacturers recommend that you take 150 mg of krill oil capsules. However, this is not sufficient to get enough EPA and DHA levels to boost blood plasma levels of omega 3, and it also does not help in therapy or clinical nutrition.
For the omega 3 to be at a high level in your blood, you need to consume more krill oil than fish oil. Considering that krill oil costs three times as much as what fish oil does, then it will be considerably more expensive for you to consume more krill oil, to get the same amount of omega 3 blood level that is achieved by fish oil.
Krill Oil Health Benefits
Krill oil is largely being used instead of fish oil as a supplement. A lot more people are starting to embrace it. Krill oil is made from a small crustacean that is mainly eaten by whales, penguins and other sea creatures. Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) and omega 3 fatty acids are derived from it. These elements are quite important to the human body and provide many advantages.
If you are unable to take the recommended 8 ounces of seafood on a weekly basis, then it is important that you take fish oil or krill oil as a supplement.
Krill oil has important health benefits, such that it is propagated to be having more benefits than what fish oil provides. This is something that is yet to be proved, as more research needs to be done on this subject.
Here are research-based benefits of consuming krill oil
Good Source of Healthy Fats
Both fish oil and krill oil are good sources of omega 3 fatty acids EPA and DHA.
There is evidence to suggest that fats from krill oil are better absorbed by the body as compared to fish oil. This is because fats from fish oil are stored in the form of triglycerides.
This is as compared to fats in krill oil, which are stored in the form of phospholipids. These kinds of fats are easily absorbed by the body.
There was research was done that proved that krill oil raised omega 3 acids more significantly in the blood as compared to fish oil. The reason that was given for this was due to the phospholipids that are found in krill oil, as they are absorbed better in the bloodstream.
Different research was done, which matched up the DHA and EPA levels that were found both in krill oil and fish oil. It was concluded that both oils raised omega 3 levels in the blood at the same rate.
However, there is still need for more research to be done to evaluate how effective krill oil is as a source of omega 3 as compared to fish oil.
Can Help Fight Inflammation
Krill oil has Omega 3 fatty oils. The oil has anti-inflammatory attributes that help to protect the body. Krill oil might be a better option when it comes to its anti-inflammatory properties as compared to other marine sources. This is because it is easily absorbed by the body.
Krill oil also has astaxanthin, which is an anti-oxidant and has anti-inflammatory attributes. It is pink-orange.
There have been studies that have been conducted to focus on the anti-inflammatory properties of krill oil particularly.
A test tube study was conducted where harmful bacteria were added to the intestines of a human being. The krill oil helped to reduce the resultant inflammation that happened.
They also conducted an experiment where 25 people, who had high-fat levels, were given 1,000mg of supplements of krill oil. It was observed that the anti-inflammatory marker was more improved with the 1,000mg as compared to when 2, 000mg of pure omega 3 oil was used. Another study, where 90 people were studied showed that after taking 300mg of krill oil every day, the inflammation marker was reduced by up to 30% after one month.
Might Minimize Arthritis and Joint Pain
Because krill oil helps to minimize soreness and swelling, it comes in handy when it comes to reducing arthritis pain and other symptoms and joint pain.
In a study that was done and showed that soreness was greatly reduced, it was also observed that krill oil helped to minimize stiffness, not being able to function as a result of injury and body aches that people who have rheumatoid or osteoarthritis experience.
In a second study, where 50 adults who had mild knee pain were observed, it was observed that patients who took krill oil for 30 consecutive days experienced reduced pain when seated or standing. Their range of motion also significantly improved.
Additionally, professionals also observed how mice reacted with krill oil. They noticed that mice that were given krill oil showed better arthritis scores. They also experienced reduced soreness and had reduced inflammation in their cells.
There is still need for more research about the effects of krill oil on arthritis. However, the studies that have been done so far support the proposition that taking krill oil is good for people who have arthritis and joint pain, therefore it is a good supplement when it comes to treating these conditions.
Can Improve Blood Lipids and Heart Health
Omega-3 fats and DHA and EPA are good for the heart. According to studies that have been done the oil from fish can enhance blood lipid levels and this applied to krill oil as well. This oil can be quite good when it comes to reducing triglycerides levels and blood fats. There was a study that compared results that krill oil gave as compared with pure omega oils when it came to cholesterol and triglyceride levels.
The effect was that krill oil increased high-density-lipoprotein (HDL) cholesterol, which is good cholesterol. It also helped to decrease inflammation even when the low dosage was used. The pure omega 3s decreased triglycerides.
An assessment of seven studies showed that krill oil helps in minimizing LDL cholesterol, which is bad cholesterol and triglycerides, while it increased the good cholesterol.
On another occasion, krill oil was compared to olive oil. The results showed that krill oil helped to improve resistance levels of insulin significantly. It also enhanced the functioning of the blood lining vessels.
There still needs to be more extensive research on how krill oil affects heart disease. However, based on the findings that have been made so far, it has also enhanced certain risk factors.
May Help Manage PMS Symptoms
The thing about omega 3s is that it can help to reduce pain and soreness.
Different research has shown that the use of supplements from fish oil can help to make such a huge difference, such that there might not be a need to use any pain medication. It can significantly reduce the discomfort felt during PMS and when has their menstrual flow.
Since krill oil has omega 3 fatty acids, it can just be as effective when it comes to reducing soreness.
The research was done comparing the effects of using krill oil vs. using fish oil to manage women who had PMS.
The outcome showed that both study groups, those who use krill oil and those who used fish oil, experienced significantly improved symptoms. However, it was noted that women who used krill also had enhanced symptoms that were much better than those who used fish oil.
The conclusion is that since krill oil has omega 3, it is quite as good as another omega 3 sources when it comes to managing PMS symptoms.
Easy to Add to Your Routine
The good thing about krill oil is that it can be easily purchased at pharmacies or even online shops. The pill sizes are much smaller as compared to fish oil supplement pills. The pills are also much less likely to reduce the fishy burps that most people get after taking the supplements.
Krill oil is in abundance since there are plenty of kills. Also, krills reproduce much faster than fish. Also, it also has astaxanthin, which fish oil does not. However, it is much more expensive as compared to fish oil.
According to health institutions, the recommended dose of DHA and EPA is 250g-500g in a day.
Before taking the supplements, you need to follow the instructions given by the manufacturer or by your doctor. Nevertheless, more research’s till needs to be done to establish the right dosage for the pills.
Note that it is not advisable to take more than 5000mg of this EPA and DHA, whether you are getting it straight from your diet or from supplements.
There are some people who should not be taking EPA and DHA. This includes people who are on blood thinning medication, women who are pregnant or breastfeeding and women who are being prepared for an operation.
When taken in high doses, omega 3 fatty acids can cause an anti-clotting effect. However, this has not been proven to have negative effects on the body. There are yet to be any studies done on pregnant and nursing mums.
If you are allergic to seafood, you are better off avoiding krill oil.
Krill and Cholesterol
There hasn’t been much research done on how krill affects triglycerides and total cholesterol. However, there are suggestions that taking krill can help to reduce your cardiovascular issues.
Both fish oil and krill oil have EPA and DHA, which are essential parts of omega 3oil. EPA and DHA are quite important when it comes to reducing triglycerides and soreness, which can have a negative effect on your blood vessels.
According to an article that was published by the Pharmacy & Therapeutics, you only need to consume 1-3g of krill oil on a daily basis, to lower your cholesterol levels and triglycerides. It does this better than the same amount of fish oil does.
You are free to take the pill at any time of the day. However, if you want to minimize chances of irritation, then it is best that you take the pill after you have eaten a meal first.
Some of the side effects that you might experience after taking this pill are that you might get a bit of gas or you might experience a fishy taste in your mouth.
Something that you should be more concerned about is the effect that this supplement will have on you when you take it in addition to other drugs.
If you are on blood thinners or antiplatelets or anticoagulants to help prevent blood clotting taking krill oil chances can worsen your bleeding problems. It can cause your blood to become thinner. This increases the chances of you bleeding more profusely in case you happen to get a cut or an injury to your body.
Therefore, it is best that you talk with your doctor first before you start taking these supplements, in case you are on blood thinners. Additional things you can do to enhance your cholesterol levels include:
Exercising on a regular basis
Losing weight, in case you are obese
Being on a healthy diet
Use satins or other medicines that will reduce cholesterol levels
In case your doctor approves of you taking krill oil supplements, then go ahead and do so and observe whether it affects your cholesterol levels.
Krill Oil Side Effects
The human body does not manufacture omega 3s. That is why we have to eat foods that are rich in omega 3s, to get this nutrient into our bodies. As much as this oil is great for human health, there are several side effects that have been noticed when you take krill oil as a supplement.
The EPA and DHA that’s found in this product are known to thin blood. Based on research that has been done by the University of Pittsburgh Medical Center, krill oil reduces the ability of the blood to clot. This is risky for people who have bleeding problems. Also, if you happen to cut or injure yourself, then it will take longer for your wounds to heal if you’re taking this supplement.
Krill oil can interact with other drugs that you are taking and have various effects. For instance, this includes medicines, such as aspirin, warfarin, ibuprofen, diclofenac, naproxen, dalteparin, enoxaparin, heparin and, diclofenac, ibuprofen, naproxen, dalteparin, enoxaparin, heparin, and warfarin. You should; it is prudent for you to talk to your doctor first before using this supplement.
Given that this oil can oxidize and get spoilt, it is important that you buy from manufacturers that have Generally Recognizes as Safe certification. So far, this is a certification that has only been attained by two manufacturers; Neptune Krill Oil and Superba Krill Oil.
Lots of people are allergic to crustaceans. If you are one of these people, then don’t take krill oil. If you do, you might have a bad reaction that might require you to get hospitalized. If you experience any negative reaction to krill oil, it is important that you stop using it immediately and that you consult a medical doctor.
Krill and Environmental Impact
A lot of marine creatures feed on krill as their main food source. As more and more kills are being harvested, there is a concern as to the effect this will have on the environment and the food chain.
That is the reason why “Commission for the Conservation of Antarctic Marine Living Resources” (CCAMLR) was set up. The main aim of this organization is to manage the fishing of krill, considering that this fish cannot be farmed, as it can only be found in the ocean.
That is why you should find out how the krill oil that you use has been sourced.
Tricks used by krill oil sellers
If you have been researching about krill oil, you might have come across several products, and you might have been left wondering about which brand is the best so that you buy it.
In some cases, the oil that you buy might have sufficient phospholipids but lack enough omega 3 fatty acids for you to find it useful. This is known as ‘weak’ oil. There is no point in buying oil with low amounts of omega 3 fatty acids since this is the main reason you are making this purchase in the first place.
Tricks and Manipulations of Krill Oil Sellers
Since it is normally quite challenging to fish in the ocean, the krill are normally harvested during certain months only when conditions are favorable. This means that most fish oil is a couple of months old.
A company might be selling a product that does not have contaminants, but it could be ‘weak’ oil.
Capliques have not been proven to be better than soft gels. In any case, they have a higher chance of leaking even before delivery and ruining the entire bottle.
You won’t get any fishy burps or fish smell, whether you are using capliques or soft gels.
