In researching the quality differences in fish oil supplements we found a company in New Zealand that that has quality standards far above their competition. It's called Xtend-Life Natural Products. It's a family-owned manufacturer and distributor of natural supplements and skin care products. This page takes a close look at their standards for fish oil.
A closer look at fish oilWe have already covered the anti-inflammatory benefits of fish oil. Like any supplement on the market there are good and bad ones. This turns out to be especially true for fish oil. Low quality products may be contaminated with heavy metals, PCBs or dioxins. Such low quality can also limit the anti-inflammatory benefits of omega 3 fish oil.
Your digestive system converts food particles into natural molecules that the body can easily absorb. The food particles are now said to be bio-available to the body. When it comes to fish oil, the benefits can only start taking effect once the body has absorbed the nutrients contained within it. The more natural the molecular structure the more easily your body can absorb them.
(Ethyl Esters versus Triglyceride forms)
Xtend-Life?s Omega 3 / DHA Fish Oil is the perfect blend of 50% exceptionally pure, natural hoki fish triglyceride oil and 50% highly purified molecularly distilled ethyl ester tuna oil. The hoki fish is one of the best sources of omega 3 fish oil.
When measuring the purity of fish oil products, there are international standards but those standards have been set with the fish oil industry in mind rather than the wellbeing of the consumer. Fortunately the people at Xtend-Life have set their standards higher.
We found the purity standards at Xtend-Life to be better than the Global Organisation for EPA and DHA Omega-3 (GOED), better than the Council for Responsible Nutrition (CRN), better than the European Pharmacopoeia, and better than the Norwegian Medicinal Standard. In this case "better" means a higher standard, which means lower levels of contaminants, as low as three parts per billion.
A current Certificate of Analysis, which is published on their website, backs up these figures.
At Xtend-Life, they endeavor to give you the freshest products possible. They are so confident that their fish oil is the freshest in the world, they encourage you to cut open a soft gel of Omega 3 / DHA Fish Oil and smell it. You should only smell a faint oceanic aroma ? if anything at all.
Their Omega 3 / DHA Fish Oil is so fresh that they guarantee no burping or fishy taste. That is, as long as you don?t have any digestive ailments which could compromise your system. They will even give you a refund on the return of the partially opened bottle should you not be entirely convinced.
Note that the unpleasant burps that taste like fish, which you may have experienced with other fish oil supplements, was likely due to a rancid product.
How to determine the freshness of fish oil
Freshness is measured by oxidation. Always look for the total oxidation (TOTOX) value on the supplier?s COA ? it is made up of two components:
Some manufacturers in Europe do not publish their anisidine values and although the peroxide values may be reasonable, the overall TOTOX value can be very high.
Interestingly, some manufacturers do their testing just for the peroxide value (conveniently after encapsulation and after an elapsed period of time). The peroxide values in a soft gel actually go down over time but the anisidine values go up, therefore pushing the TOTOX value up as well.
It is a trick of the trade that some manufacturers use. Although the ?N/A? indication on the COA may mean ?Not Available?, it should really mean ?Not Acceptable? ? don?t be fooled.
The table below shows comparative oxidation specifications between acceptable international standards and Xtend-Life standards. All of the indicated values are absolute minimum standards.
MORE ABOUT DHA AND EPA
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:
