The comparison might not be palatable, but fish oils are not unlike cocktails.  Like fine liquor, tuna oils have a veritable pedigree.  But if you're looking for ways to improve your health, you might want to look for a good mixer instead of serving it neat.


South Pacific tuna is generally recognized as the best source for fish oils supplements because it contains the most effective form of fatty acid called DHA.  It is usually bunched with its lesser cousin, EPA, into what is popularly known as "Omega 3", but studies indicate that it is DHA that induces the majority of the benefits in the human body...especially when used in combination with EPA


DHA fats serve a unique function in our diets: once assimilated, DHA is converted into an anti-inflammatory chemical potent enough to act throughout the body.  This mechanism is responsible for the lower incidence of sudden death from stroke or heart attack in fish oil consumers.  As an indispensable component of your brain, DHA also suppresses depression and anxiety episodes, and generally leads to brighter moods.


There's a caveat, however.  Pure tuna Omega 3 oils doesn't find its way into our bloodstream too easily.  To aid absorption, it should be blended with a substrate such as salmon oil, a product of New Zealand. 


There's also another matter of distillation.  Tuna fish are generally large creatures, which means it would have consumed a lot of smaller marine creatures throughout their lives.  These crustaceans usually carry minute amounts of toxic heavy metals such as lead, arsenic and mercury.  Since no organism can excrete them naturally, the poison would accumulate in the tuna flesh in a considerably more concentrated dosage.


Molecular distillation leaves these dangerous chemicals behind by evaporating the lighter oils into a pristine Omega 3 distillate.  This is necessarily a convoluted and expensive procedure, so many manufacturers skip the step, figuring that the symptoms of poisoning won't show until it's too late.  They are right about this point, so be sure to check the labels or the website.


It takes all the patience in the world to age a fine wine, and the same might be said for preventative healthcare.  Having avoided the common and perilous pitfalls, you can now look forward to a worry-free future. Cheers to that!
