Krill oil is extracted from a tiny crustacean, very similar to a shrimp that is found in the cold seas of the Antarctic ocean and constitutes a great part of the marine fauna.
Because it is a crustacean that is found in huge amounts, it’s become the base of so many species nutrition like penguins, whales, fishes and other marine animals.
Krill is considered to be almost a treasure because it has excellent nutritional benefits like the great amount of proteins and omega-3 fatty acids it contains.
Omega-3 fatty acids are associated to cardiovascular protection properties as it increases HDL cholesterol and reduces cardiovascular risk.
Krill oil has multiple properties: it protects your heart, it has anti-inflammatory effects, it protects blood vessels, alleviates arthrosis symptoms, allergies, diabetes and reuma.
People often wonder how krill oil can help relieve cardiovascular diseases, arthrosis or the premenstrual syndrome. The answer is easy: krill oil is the most effective natural anti-inflammatory. In fact, research supports that chronic diseases and ageing processes are directly associated with inflammation.
After 12 weeks taking krill oil, cholesterol usually decreases by 13%, LDL by 32%, triglycerides by 11% and increases HDL by 44%.
Krill oil reduces the premenstrual syndrome
After 3 months taking krill oil, irritability decreases by 47%, depression by 40%, water retention by 37% and abdominal pain by 33%.
Krill oil mitigates joint pains
After taking krill oil for one week, joint pain gets reduced by 24%, stiffness by 22% and flexibility increases by 16%.
Krill oil has many more benefits
It provides energy, strengthens the brain, protect the skin (sun protection from the inside), fights wrinkles, etc.
Krill oil, its benefits as an anti-inflammatory
Most people eat too much omega-6 (sunflower oil, safflower oil, corn oil, hydrogenated vegetable oils, eggs, etc.) and too little omega-6 (fatty acids like salmon, tuna or Atlantic mackerel).
This imbalance provokes the inflammation of body cells, which, in a long term and before we notice, provoke a great damage, not being visible.
Recent research have proven that inflammation is the main cause for many diseases: cardiovascular diseases, osteoarthritis, cancer, allergies, diabetes, reuma, high blood fat levels and nervous diseases.
Inflammation also accelerates the ageing process and affects well-being. Krill oil naturally inhibits cell inflammation.
Nutritionists and nutrition professionals underline how important omega-3 fatty acids EPA and DHA contained in krill are for people, because krill oil deficiency contributes to the appearance of many diseases.
Omega-3 fatty acids are essential polyunsaturated fats for the development of the central nervous system, with a fundamental role in blood coagulation, normal blood pressure and cholesterol control, beside its anti-inflammatory contribution.
Our daily diet, includes too much Omega-6 and not enought Omega-3, causing an unbalance in our body. Omega-6, however, stimulates inflammatory processes in the organism.
Omega-3, contained in this oil, makes the organism go back to a normal state. An excessively low level of these essential polyunsaturated fats will increase the risk of suffering inflammatory diseases.
Neither Omega-3 or omega-6 are produced by the body, but they have to be supplied. Krill oil contains a ratio of 15-1 (omega-3 - omega-6), so it can compensate the imbalance of the organism. This way, the risk of suffering inflammatory processes decreases, as well as inflammation is reduced if has already developed.
Scientists are increasingly interested in the inflammation role in health or diseases; currently, inflammation is one of the most investigated areas in medical research.
These studies show that heart attacks and cerebrovascular diseases are potentially associated with high levels of c-reactive protein.
Krill oil effects on inflammation (C-reactive protein or CRP)
C-reactive protein levels in blood are reduced by taking 300 mg of krill oil a day.
After 7 days, they decreased by 19,3%.
After 14 days, they decreased by 29,7%.
After 30 days, they decreased by 30,9%.
Krill oil, the antarctic omega-3
Krill oil is extracted from krill, a type of shrimp that lives in the cold seawater of the antarctic ocean.
This crustacean is the food supply of the biggest marine animals and it’s not contaminated by heavy metals or toxins, that are harmful for our health.
Each year, only a small part of krill is captured. Because they reproduce so fast, krill provision is almost unlimited.
These crustaceans, similar to shrimps, live in huge sandbanks in the cold and clear Antarctic waters.
What is krill oil?
Krill oil combines three very valuable and vital substances within its composition:
Krill oil contains omega-3 fatty acids and has been proven to be fundamental for a good health and well-being. However, they are not produced by the body and have to be food supplied.
The body needs omega-3 fatty acids to keep the body cells repaired. They are also very important for the central nervous system as well as for blood coagulation, which has a decisive influence on cholesterol, blood pressure and prevention and treatment of inflammation.
Furthermore, krill oil has a positive effect on intellectual performance and has been proven to have a remarkable effect on mood, concentration and alertness.
Omega-6s, which we often overeat, help the body cause the inflammation that fights infections. Fatty acids help the body to successfully fight infections caused by inflammation. Therefore, an Omega-3 deficiency can have serious health consequences.
Unlike other fatty acids, krill oil has an important antioxidant effect. Antioxidants are substances that protect the body cells from free radical consequences.
Also, nutritional supplements contain special fats called phospholipids, a basic component of the cell membranes that also protect our body from free radicals.
In addition, krill oil omega-3 fats provide resistance to stress, as brain cells depend on the omega-3 supply. In this regard, krill oil also contributes to improving cognitive performance and memory.
As a third part of the combined triangle of basic nutrients, krill oil is a potent natural antioxidant that helps counteract the damaging effects of oxygen molecules (free radicals).
What’s more, it works against oxidative stress, which is responsible for a lot of health problems.
Krill oil is rich in antioxidants
Clinical analysis have proven that krill oil has an incredible antioxidant blend with powerful effects that not only provide health benefits but they also keep health stable (unsaturated fats tend to be highly sensitive to oxidation).
Krill oil antioxidants inhibit that unpleasant “fishy” taste, which is often very noticeable in other omega-3 oils.
Krill oil is rich in astaxanthin
The most powerful antioxidant of krill oil is astaxanthin, a carotenoid that belongs to the beta-carotene family and contains lutein and lycopene. It has been proven that all these ingredients have special properties to inhibit the ageing process.
A remarkable characteristic of this carotenoid contained in this krill oil, is that it is completely esterified, that is only attached to EPA and DHA molecules.
This means the body can apply it and benefit from its considerable antioxidant properties. Astaxanthin can also get through the blood-brain barrier, which means that it protects and stimulates the brain.
This carotenoid, that krill oil contains, offers a fantastic protection against UVA rays and against skin damaged by UVA rays, thus delaying the ageing process.
Antarctic krill oil has a very high content of astaxanthin in comparison to other products, which is very beneficial for the overall health as it stabilises the organism and protects from oxidative processes.
Krill oil also contains a new flavonoid that it’s normally found in plants and has a really powerful antioxidant capacity.
Krill oil has a high ORAC value
ORAC is a standard laboratory test that is used to assess the proportion of several antioxidants. The minor the amount, the minor the effects.
It has been proven that the antioxidants found in this oil have an incredible potential.
Krill oil antioxidants have been ORAC (Oxygen Radical Absorbance Capacity) tested and the results were unexpectedly high, which means it has a greater antioxidant feature than other elements.
Compared to other oily antioxidants, krill oil has a really high ORAC value: 378. This means that its antioxidant effect is 300 times greater than vitamin A or vitamin E, and 48 times greater than omega-3 in conventional fish oil.
A unique combination
The benefits and properties that krill oil provides are still being researched.
Currently, experts have already stated that its extraordinary properties come from the three main ingredients (omega-3 fatty acids, phospholipids and antioxidants) of krill oil.
Krill oil: joint pain support
Great part of clinical trials with krill oil refers to its effects on the prevention of chronic joint pain and inflammation.
During a series of trials, carefully controled, scientists analysed the effects of krill oil in patients with osteoarthritis, rheuma or high blood levels of c-reactive protein (CRP), a protein that is produced by the liver as a response to an inflammatory sign. Results were very encouraging.
Effects on joint pain after only seven days taking krill oil:
Pain reduction by 24%
Stiffness reduction by 22%
Flexibility improvement by 16%
What is inflammation?
Inflammation corresponds to the swelling and pain caused in joints.
Inflammation is produced when the immune system responds to the body to destroy the germs that invade the infected tissues.
Once the infection stops, inflammation reduces and the healing process begins. Sometime, however, this inflammatory process does not end and becomes a chronic issue.
Joint pain and inflammation
Rheuma inflammation is provoked because the immune system responds incorrectly for unknown reasons and attacks its own joint tissues. Which happens next is just a classic example of the basic inflammatory process.
White blood cells accumulate in the joints and launch an attack, releasing inflammatory substances (interleucines and others). Consequently, this produces pain, inflammation and reddening of joints.
A great part of osteoarthritis inflammation and pain occurs because the joint cartilage literally tires over time. This wear causes chronic inflammation and of the affected tissues, pain, swelling and numbness.
Inflammation reduction is the key to alleviate joint pain and osteoarthritis symptoms.
Doctors usually recommend taking anti-inflammatories to relieve or suppress body inflammation. But nature has plenty of powerful anti-inflammatory agents, Omega-3 fatty acids are included.
Studies show that people suffering from rheuma taking omega-3 fatty acids feel less pain, swelling and stiffness, even with the possibility of needing to reduce anti-inflammatory medication dosage.
Antioxidants have been proven to have a great capacity to fight free radicals and providing a great anti-inflammatory effect. Both are the two main components of krill oil.
Krill oil on premenstrual syndrome relief
The first important study on krill oil showed the effects of the premenstrual syndrome symptoms.
This study was carried out in 2002 by the University of Montreal, McGill and other medical centers in Quebec. This was a randomised controlled trial on krill oil use to alleviate premenstrual syndrome symptoms (PMS). The results were published in 2003 in “Alternative Medicine Review”, (Vol. 8, No. 2).
The clinical trial carried out for 3 months concluded in the patented ingredients of Krill oil reducing physical and emotional symptoms related to the premenstrual syndrome and painful periods, also known as dysmenorrhea.
The participants were asked to classify the seriousness of the symptoms on a scale of 0 to 10. Their state was assessed in the beginning, after a krill oil treatment for 45 oil, and after 90 days.
The result showed that the PMS symptoms were considerably reduced, from 20% up to 60%.
What is the premenstrual syndrome?
Between 85 and 97% of women of childbearing age suffer from pain, discomfort and emotionalswings every month, which is directly related to the menstrual period.
Symptoms vary depending on the woman and the month.
Normally, PMS symptoms are continuous and unpleasant from chocolote cravings to a wide range of physical problems (breast pain, belly pain, belly cramps, water retention, weight gain, body pain, fatigue and headache).
Why does krill oil alleviate PMS symptoms?
The extraordinary results of krill oil were attributed to the molecule profile of krill oil, composed of phospholipids, omega-3 fatty acids and several antioxidants.
A thesis was formulated suggesting that phospholipids and omega-3 fatty acids (mainly DHA and EPA) work together to stop inflammation, which is the main cause of the most of Premenstrual syndrome symptoms. Furthermore, phospholipids are known by its calming effects on brain neurotransmitters, affecting emotional and physical symptoms.
After clinical studies during three months, it was decided to believe and trust the capacity of krill oil to reduce emotional and physical symptoms caused by the premenstrual symptoms.
Krill oil is the perfect natural prescription
Krill oil contains omega-3 fatty with an anti-inflammatory rate regarding omega-6 of 15-1.
Krill oil reduces cholesterol
The second important study on the benefits of krill oil for human health focused on the effects of high levels of lipids in blood.
High levels of lipids in blood are a risk factor to suffer from cardiovascular and cerebrovascular diseases.
The study was carried out by the University of Montreal, University of McGill and the Medical Center of Riverview in Montreal on the effects of krill oil on hyperlipidemia (which causes the increase of fat blood levels and cholesterol).
During 3 months, researchers assessed the levels of total cholesterol (LDL and HDL) and triglycerides on krill oil treatment. The study was published in “Alternative Medicine Review” in 2004 (Vol. 9, No. 4).
The study concluded on krill oil reducing considerably total cholesterol and triglycerides - LDL levels, increasing however HDL cholesterol levels.
What it cholesterol?
Even if you’re thin and healthy, you can have high cholesterol levels, which implies the risk of suffering heart diseases or cerebrovascular diseases.
Cholesterol is part of a lipid group (blood fat), which is essential to produce hormone, nerve fibres and cellular membranes.
However, cholesterol can become a problem if there is an excess of it. Normally, the liver produces all the necessary cholesterol. If you eat food with a high level of cholesterol or saturated fats, the liver will respond by releasing even more cholesterol.
Over time, this excess accumulates in arteries and they harden, forming a fibrofatty plaque. If this is not treated, the organism can develop atherosclerosis, angina, heart attack or strokes.
Know your blood lipid levels
It’s important to keep your lipids in a healthy rank.
The optimum level of cholesterol should be under 200 mg/dl. Also, the main two groups of cholesterol should be known by everybody. LDL should have a lipoprotein concentration lower than 100 mg / dl, and HDL should have a concentration of 60 mg/dl.
(Lipoproteins are small drops of fat and protein that helps transport this fat in cells through our body.)
Triglycerides, the other type of lipids, must be lower than 150 mg/dl. Triglycerides are formed from the most common fats in food (90% of the fat we consume) and are the main energy source for the body. Each type of lipoprotein has different effects on health.
The higher your LDL levels, the higher the risk of suffering heart diseases.
On the other hand, HDL levels reduce the risk of suffering cardiovascular diseases because it transports the cholesterol to the liver, where it is processed by the metabolism and it’s finally excreted.
High levels of triglycerides help the blood thicken and make people more sensitive to suffer arterial thrombosis. These high levels of triglycerides are produced as a side effect of cholesterol and other risk factors to suffer heart diseases like obesity.
Keeping optimum Low Density Lipoproteins levels
Nowadays, heart diseases and strokes are the most frequent causes of death in United States, Canada and a great part of the western countries. High cholesterol levels are a very important risk factor to develop this kind of cardiovascular diseases.
The American Heart Association estimates that nearly 150 million people in USA have a cholesterol level higher than the limit (200 - 239 mg / dl).
As a result of a study, the government has been asked to take action regarding those people who are in the high-risk group (for example, those who have suffered a heart attack), with the objective of adjusting the levels to the standard recommendations.
Doctors, for their part, have responded through the prescription of cholesterol reduction treatments.
In addition, people are suggested to start healthy habits like exercising, weight control, stop smoking, reduce stress and eat healthy foods that are good for the heart (less fat and trans, more fruit, vegetables, cereals, oily fish).
Krill oil prevents cardiovascular diseases
Scientists became aware of the benefits of fish oils when they realised the low rate of cardiovascular diseases in Greenland eskimos, despite their fatty diets.
According to research, the reason for this is the high amount of omega-3 fatty acids contained in fish, which is in the daily diet of an Eskimo.
This theory was confirmed by other studies, as well as the protected route of krill oil to reduce cholesterol, triglycerides and LDL, and increase HDL.
Therefore, omega-3 fatty acids prevent artery inflammation, which is a factor that contributes to the formation of fibrolipid plaque or the hardening of the arteries.
Why is krill oil heart-healthy?
Research has concluded that the beneficial effects of krill oil are due to its unique molecular structure.
Krill oil has a high content of phospholipids and antioxidants (especially astaxanthin), which explains its amazing effects on the regulation of cholesterol and other blood lipids.
The investigators have reached the conclusion that it has an extraordinary combination of substances with superior effects to prevent cardiovascular diseases.
Krill oil reduces cholesterol
The study showed that a dose of 1.0 to 1.5 grams of krill oil a day had more significant effects on LDL cholesterol and triglycerides reduction than a dose three times higher of other fish oil (3 grams a day). Higher doses of krill oil reduces triglyceride levels in blood, which does not happen with other fish oil.
Results of the study:
1,000 mg of krill oil after 90 days reduced:
Total cholesterol - 13,44%
LDL - 32.03%
HDL - 43,92%
Triglycerides - 11: 03%
Maintenance dose of krill oil 500 mg a day after 180 days, reduced:
Total cholesterol - 18,90%
LDL - 44,40%
HDL - 33,40%
Triglycerides - 25.40%
Krill oil is the only natural product that can reduce the cholesterol level with a lower dose than any other product.
Krill oil and better looking skin
Due to krill oil’s powerful antioxidants (especially astaxanthin), it protects the skin from damage and inflammation caused by UVA rays. For the first time in history we have a capsule that protect skin from sunlight.
On the other hand, 58% of women who answered a survey on quality of life, stated that krill oil had reduced their wrinkles and other skin problems like reddening.
One of the participants said “My skin is less dry and much softer, and my scalp eczema has been reduced.”
In fact, the action of krill oil on eczemas and psoriasis is currently being investigated.
Astaxanthin protects cells from the oxidative processes, from the simplest cellular damages all they way through the most complex like carcinogenesis.
It also improves the hair and nails look. Women who participated in the survey, admitted to have shinnier hair, a reduces hair loss and stronger nails. These positive effects are due to the high content of omega-3 fatty acids contained in krill oil.
Krill oil increases energy
In the survey, 51% of participants said to have felt more energy as less drowsiness while taking krill oil. A man said he even stopped taking his usual nap.
A canadian business student wrote:
Now I live my life at an incredible speed, before I felt empty and lacking of energy. Thanks to krill oil my mental fatigue has been reduced and I feel my acuity has increased considerably.
Sportsmen have also confirmed a greater performance and endurance while taking krill oil. It’s believed that this is due to its high choline content, which is a key component of acetylcholine, along with omega-3 fatty acids. Athletes said they can train faster and better.
Increases concentration and attention
In study cases of children with dyslexia, Attention-Deficit/Hyperactivity Disorder (ADHD) or Autism, the parents noticed a significant improvement in the concentration and attention of their children after starting to take krill oil.
Once more, these results are due to the omega-3 fatty acids (in particular DHA, in the form of phospholipids, an important constituent of the brain). People have stated that they no longer needed a nap and that they could concentrate on highly complex mental situations.
Krill oil helps hay fever
Due to its anti-inflammatory properties, krill oil reduces rhinitis, wheezing, runny nose and eye pain, which are related to the immune system response to pollen and other microscopic allergen particles.
Krill oil reduces autoimmune diseases
A study of the American College of Nutrition magazine, 2002, stated that omega-3 fatty acids can provide significant improvements to the patients suffering from inflammatory and autoimmune.
Currently, several trial are being carried out to go deep in the effects of krill oil on rheumatoid arthritis, multiple sclerosis, crohn's disease and systemic lupus erythematosus.
Recent studies are focused on the benefits of krill oil on prostate and breast cancer, as they both have a positive response as it is also a hormone regulator.
The amazing Krill oil
Euphausia superba, is a multicellular species with the greatest accumulation on the earth (biomass). The estimated amount of krill in the Antarctic Ocean around the Antarctica is among 135 and 670 million tonnes.
In the recent years, the annual capture of commercial fishing in the Antarctic Ocean was from 102,000 to 110,000 tonnes, much less than the quotas imposed by the Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR). This ensures the conservation of krill species in the Antarctic Ocean and the continuation of its incredible oil in a foreseeable future.
The fact that krill oil is available as a dietary supplement has no harmful effects on the environment as the annual capture represents only a 0.03% of the estimated krill production.
Even the WWF and the CCAMLR confirm such estimation, so krill oil can be considered as ECOSAFE.
Everybody, all the way from russians to japaneses, tried to find an economic method to capture krill in the Antarctic Ocean and offer it as food, but no method was successful since frosting and defrosting krill means a very short lifetime. This is how came up the idea of capturing molluscs to use their therapeutic oil.
Scientists tried to obtain krill oil from Antarctic without destroying its nutrients, but they would always fail. This changed thanks to Neptune Technologies & Bioressources patented processes.
A team of scientists spent five years trying to find out how to obtain krill oil and keep its beneficial properties intact. Finally, collaborating with Sherbrooke University in Quebec, it was developed a unique extraction process to not alter its properties.
Which foods contain krill oil?
There are many fishes that are rich in omega-3 fatty acids like Atlantic mackerel, salmon and tuna. However, krill oil is much healthier and beneficial for the human body, only found in krill crustaceans that live in the Antarctic ocean.
Which are the symptoms of omega-3 deficiency?
Omega-3 deficiency can cause body inflammation or a chronic inflammation that is not properly healed.
Omega-3 can also cause a faster ageing process in the skin and brain cells.
How to take krill oil
Krill oil, as a nutritional supplement, should be taken right before a meal several times during the day. Krill oil has not side effects or interactions with other drugs.
Krill oil is particularly recommended for:
People who needs to be active and healthy
People who want to protect their cells
Women with PMS
People with high cholesterol levels
Preventing cardiovascular diseases
What do the experts on krill oil say?
Studies show that krill oil presents so many advantages in comparison to other products containing Omega-3 fatty acids.
Experts also believe that krill oil has a positive effect on women with PMS. Many of the PMS symptoms can be reduced up to 50% by taking krill oil.
Krill oil, naturally healthy
This crustacean finds it self at the beginning of the food chain and eats plankton plants, which does not contain toxic heavy metals or other harmful substances.
Krill oil originates in Antarctic seas.
It’s one of the most numerous species on the earth and constitutes the main food source for many marine animals, especially whales and penguins.
The fact that krill oil is available as a dietary supplement has no impact on the ecological balance in the Antarctic, as the annual catch represents only 0.03% of the estimated total krill population.
Even the WWF (World Wide Fund for Nature) and the International Commission for the Conservation of Antarctic Habitats (CCAMLR) have confirmed this data.
If you suffer from PMS, have high cholesterol levels, joint pain or you just want to stay healthy, krill oil will definitely help you.
However, it’s important to know the following information whenever you decide to purchase and use krill oil.
What you should know when buying Krill Oil
Remember: Not all krill oil products are the same. When you buy krill oil, check if it comes from the Antarctic ocean.
It’s important to have been obtained through a cold water extraction process so that it keeps its sensitive bioactive ingredients intact.
It has been clinically tested that krill oil is a quality source of phospholipids, as well as it contains a high concentration of antioxidant astaxanthin and it’s rich in important omega-3 fatty acids EPA and DHA. Furthermore, krill oil is an excellent choline source.
Correct dosage of Krill Oil
During the first two weeks, take 2 - 4 500mg capsules. Then reduce the dose to 1 - 2 capsules a day. The necessary amount of krill oil depends on the purpose of each person.
Generally, a dose from 300 to 1,000mg of krill oil a day is more than enough for most of health problems.
When should I take krill oil?
Krill oil can be taken anytime. The most recommendable is to take it before meals and/or breakfast.
When will I start seeing results?
If you suffer from joint pain, you’ll see results in a few weeks. Regarding cholesterol levels or PMS, results will appear after 2 - 3 months of regular treatment.
Taking krill oil daily will improve your skin, hair and nails, brain functions, allergy symptoms and your general well-being.
Side effects and interactions of krill oil
Krill oil does not have side effects on its recommended dosage. Maybe the person just feels more energy and activity.
Patients who suffer from some blood coagulation disorder, should first consult a doctor on the matter.
Even if you present allergy to shellfish it should not cause problem as normally this allergy is causd by the proteins from these shellfish and pure krill oil does not contain proteins so the probability of having any intolerance is remote.
It is still advisable to be cautious and consult your doctor. In any case it is best tocarefully checked the product's label, where all the information regarding allergens of the product must be detailed.
In relation to the interactions of krill oil with other products, it is advisable to inform the doctor if anticoagulants are being taken. Just like if you are taking other medications such as estrogens, etc.
