Fish oil is widely acclaimed for its health giving properties – the benefits of which span across the entire health spectrum. However, considering the vast range of fish oil suppliers and products currently available, you’ll understandably be hard-pressed to find the one that is not only the most effective, but also the purest, freshest and most natural fish oil in the world – well, at least until you’ve finished reading this article.
Every effect has a cause. One thing leads to another – it’s a fact. In terms of aging and deteriorating health conditions, your body’s main culprit is almost always inflammation. What makes inflammation so deadly is that it sneaks up on you and over time, the cumulative effect is a chain reaction of various health conditions ranging from arthritis and chronic pain to more serious issues such as atherosclerosis, aneurisms, strokes, brain disorders and ultimately, death.
Why is fish oil so important?
Most scientists and health professionals believe that it is the anti-inflammatory properties of fish oil that enable it to provide so many health benefits particularly in areas of the: Heart, Brain, Joints, Skin, Immune system, Vision and, Digestion.
However, like any nutritional product on the market today there are good and bad ones. Fish oil is no exception. With a bad one you may be unwittingly introducing substances into your body that you do not want, for example: mercury, PCBs or even increasing your load of free radicals.
You owe it to yourself to use only the purest, and thus the safest omega-3 fish oil available, plus it also has to be the most effective in order for you to receive the benefits above. If you and your family want the best product possible there are certain ‘rules’ that you need to follow.
- Â·Â Â Â Anti-inflammatory properties: Does your current fish oil have the best possible anti-inflammatory properties?
- Â·Â Â Â Bio-availability: It must be in its natural form.
- Â·Â Â Â High content of quality omega-3 and DHA: Be reasonably high in omega-3 with the dominant essential fatty acid being DHA.
- Â·Â Â Â Purity: The fish oil must be free from any contaminants with supporting evidence to prove it.
- Â·Â Â Â Freshness: This means low oxidation levels; once again with cold, hard evidence to back-up such claims.
These ‘rules’ will be individually explained in more detail throughout this article.
Omega-3’s best catch of the day
Which fish species is the most effective when it comes to inhibiting inflammation?Â Our research points to hoki.
In addition to its exceptionally high levels of purity and freshness (when correctly handled and processed), hoki fish also seem to contain a fascinating ‘x-factor’ which turbo-charges the efficacy of its oil – especially when combined as a natural triglyceride with a highly concentrated and molecularly distilled fish oil (more about this ‘x-factor’ and the various types of fish oils will be revealed later).
This fish is found off the coast of New Zealand in the Southern Ocean. The hoki fishery in New Zealand is controlled by the New Zealand government and is considered to be the best managed and sustainable fish resource in the world.
Unlike most fish which are caught by large factory ships and frozen at sea, hoki fish are caught by smaller vessels fishing within seven hours travelling from the hoki fishing grounds. The catch is able to be kept fresh in ice and processed immediately upon arrival back on shore.
Amazing anti-inflammatory alchemy
As mentioned earlier, inflammation is VERY important, it can have profound detrimental influences to your heart and cardio-vascular system, as well as being a precursor for many other ailments. This is why Xtend-Life researchers have focused so much on improving the anti-inflammatory properties of the Omega 3 / DHA Fish Oil with amazing success – a product that is now setting new standards for fish oil products.
This was established as part of a study carried out this year by Trinity Bioactives, part of the Wellington School of Medicine in New Zealand.Â The study tested the inflammation inhibition properties of three fish oils while using aspirin as a dose-related control. The three fish oils were:
- Â·Â Â Â A concentrated tuna oil with 85% omega-3
- Â·Â Â Â A ‘normal’ consumer fish oil 18/12 which consists of 18% EPA and 12% DHA
- Â·Â Â Â Xtend-Life’s Omega 3 / DHA Fish Oil
- Â·Â Â Â Normal fish oil – 14%
- Â·Â Â Â Concentrated tuna oil – 20.6%
- Â·Â Â Â Xtend-Life’s Omega 3 / DHA Fish Oil – 38.1%
Your digestive system is probably the most efficient production line known to man, however it is as natural as nature itself. It converts food particles into natural molecules that the body recognises and therefore can easily absorb. The food particles are now said to be bio-available to the body.
Bio-availability is influenced by the molecular shape of fatty acids, sugars, proteins, and other nutrients that are easily absorbed by the body. When it comes to fish oil, the benefits associated with it can only start taking effect once the body has absorbed the nutrients contained within it. The more natural the molecular structure the better.
So, when assessing how ‘natural’ fish oil is, it is important to know about the different forms currently available on the market:
- 1.Â Â Â Natural fish oil comes in a triglyceride form. This is the oil that you get when you ‘squeeze’ the fish and extract the natural oil from it. The drawback from this particular form of fish oil is that it usually has low overall omega-3 content because it’s not concentrated and generally has high levels of contaminants such as heavy metals, PCBs, dioxins etc.
- 2.Â Â Â Ethyl ester oil occurs when you take natural triglyceride oil and concentrate it whilst molecularly distilling the oil to eliminate purities. The concentration process cannot take place until the natural triglycerides are converted to an ester form. The ester form is still in a semi-natural state because it is the result of a process that naturally occurs in the body to allow for bio-availability. It’s not uncommon to double or even triple the omega-3 content of a fish oil using this concentration process.
- 3.Â Â Â Synthetic triglyceride oil is another form of fish oil that is very common and marketed as ‘natural’ when in fact it isn’t. It is a triglyceride, but not a natural one. It is produced after concentration. As mentioned above, the natural triglycerides are converted to ethyl esters for concentration. This is perfectly fine however; but some manufacturers then re-convert the esters back into triglycerides – a synthetic form which occurs as a result of this re-conversion process. The original position of the triglyceride’s carbon bonds change and the molecule’s overall structure is altered. Part of it becomes foreign to what the body is used to – negatively impacting the bio-availability of the fish oil. Why do they do it? Because they can state that it is a triglyceride form and infer to the customer that it is natural – which in actual fact, it’s not.
It’s about quality and synergy
There are some fish oil products out there that are saturated with high levels of omega-3.Â However, both history and science have proven time and time again that it is quality and naturalness not quantity that’s important.
As an example, there is a highly concentrated omega-3 fish oil produced by a pharmaceutical company that has an exceptionally high omega-3 content (about 98%). It is registered as a drug and approved by the US FDA for treating high triglycerides. However, recent studies have shown that in addition to reducing triglycerides (which is good), it actually also increases cholesterol levels (which is bad). However, ‘normal’ fish oil lowers both triglycerides AND cholesterol. Obviously, there is some beneficial component of the fish oils that is removed in the highly concentrated oil.
Why is DHA in the spotlight?
DHA (Docosapentaenoic acid) is without a doubt the most complex and beneficial fatty acid as far as the human body is concerned (more so than EPA) as it is a 22 carbon chain bond with six (cis) double bonds. You see, DHA is essential for the growth and functional development of the brain in infants. It is also required for maintenance of normal brain function in adults.
The inclusion of plentiful DHA in the diet improves learning ability, whereas deficiencies of DHA are associated with deficits in learning. DHA is taken up by the brain more readily than any other fatty acid.
Other omega-3 fatty acids follow DHA in order of complexity, number of carbon chain bonds and overall efficacy for your body. They are:
- Â·Â Â Â EPA (Eicosapentaenoic acid) has 20 carbon bonds. It is difficult for the body to convert EPA to DHA because it has to add two carbon bonds. On the other hand the body only has to ‘drop off’ two carbon bonds from DHA to create EPA.
- Â·Â Â Â ALA (alpha linolenic acid) – commonly found in flaxseed oil, this omega-3 fatty acid only has 18 carbon bonds, making it almost impossible for the body to manufacture DHA from.
- Â·Â Â Â A special mention must be made with regards to another omega-3 fatty acid – DPA (Docosapentaenoic acid). It acts as the ‘sidekick’ for both DHA and EPA. The
