Why seek pure omega3 oil? If you’re concerned about your health, you will want to make sure you get an omega3 supplement that is free from additives and free from contaminants. But not all supplements fulfil these criteria – despite what they might claim on the label.

Pure omega3 fish oil supplements should contain nothing but fish oil and some natural antioxidants, such as rosemary extract and broad spectrum natural vitamin E oil (tocopherol) to act as a preservative. The ingredients don’t need to be any more exotic than that and you should be suspicious of any omega-3 supplement marketed as ‘pure’ that includes any extra ingredients.

In terms of contaminants, it’s an unfortunate fact that many fish species are caught in waters contaminated by PCBs, heavy metals and dioxins. Oily species, such as salmon, mackerel and tuna, are particularly likely to contain such toxic substances because they are high up the food chain. Unfortunately, they are also the species you need to eat to get a good dose of omega 3 fatty acids.

Manufacturers of fish oil supplements must therefore put their product through exhaustive purifying and filtering processes to arrive at something that can be called pure.

But it is possible to find supplements that are naturally low in contaminants. These will use the fish species hoki, which is caught wild in the clean waters of the Southern Ocean, off the coast of New Zealand. Any lingering contaminants can then be removed by the sophisticated process of molecular distillation, guaranteeing a product that is genuinely pure omega3.

Purity can also refer to the amount of the omega 3 fatty acid DHA contained in each soft gel of fish oil. DHA is the most important of these essential fatty acids and is beneficial for the heart, brain and circulation. The better quality the product, the higher the concentration of DHA.

So when looking for pure omega3 oil, make sure you get a supplement that has been tested for its purity and freshness, that states its ingredients up front and that publishes proof of its lack of contamination.

Have you read about this recently?  There are many omega3 sources, although the one that always comes to mind first is fish.  Doctors and nutritionists have been telling people for years that if they want to be heart healthy, then they have to add a regular weekly rotation of fish to their diet.  That may have been a good idea at one point in time, but it is not advisable to eat large quantities of fish now.

The most recommended of the “oily” fish have always been salmon, herring, mackerel, trout, and albacore tuna.  These fish are all considered to be “predator” species, since they feed upon other species of fish smaller than themselves.  With all of the contamination that is now present in just about every body of water in the world, being higher up on the food chain causes some problems.

Even the smallest fish take in measureable amounts of toxins throughout their lives, but it seems as though when one fish feeds on another the feeding fish accumulates all of the toxins absorbed by their prey.  These larger omega3 sources tend to store high levels of lead, mercury, dioxins, PCBs, and furans.  Large predators such as sharks contain mercury levels so high that they are virtually toxic.

The reason that eating these fish is dangerous is that there is no way to control the level of toxicity.  If you are going to eat fish, then make sure that you are getting them from the cleanest bodies or regions of water possible.  You would rather eat wild Pacific Salmon for example than you would salmon caught in the more heavily polluted Atlantic Ocean.

Encapsulated over the counter omega3 sources are a far better bet in order for you to ensure that the fish oil that you are ingesting is pure.  The manufacturers of dietary fish oil supplements use a method of molecular distillation that reduces any present toxins to below measurable levels.  So with fish oil capsules you never need worry about the dangers of mercury or lead poisoning.

Most of the other sources for omega fatty acids are heavy in alpha-linolenic acid (ALA) which is good, but they are not good sources for either docosahexaenoic acid (DHA), or eicosapentaenoic acid (EPA).  Both DHA and EPA offer you far more benefits than any of the other omega fatty acids, so they are the ones that you need to be specifically concerned about getting.

Other than the level of purity that can be obtained encapsulated dietary omega3 sources are advisable because they can also offer you the correct balance of crucial omega fatty acids.  For example, in fish you are mostly getting EPA, with just a small amount of DHA.  In balanced nutritional supplements however, you are able to get more than twice as much DHA as EPA.

Make no mistake about it.  You need this sort of balance from your omega3 sources if you are going to enjoy the cardiovascular benefits, and improved brain function that these essential fatty acids offer.  Don’t endanger yourself with toxins, or leave the amount of DHA you are getting to chance.  Start taking a  balanced fish oil supplement today, and ensure yourself the good health that you deserve.
