Facts about Pharmaceutical Fish Oil

What is Pharmaceutical Fish Oil?

Pharmaceutical fish oil is a high potency fish oil supplement containing high levels of the omega 3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

The oil has undergone a special manufacturing process, such as molecular-distillation, to ensure it doesn't exceed specific levels of mercury, PCB's, dioxins and other contaminants.

How Do You Know if Your Fish Oil is Pharmaceutical-grade?

One of the best ways to determine the grade of your fish oil is check the IFOS list of fish oils.

The IFOS (International Fish Oil Standards) is a Canadian company that tests fish oils from all over the world. They use a third-party testing lab to determine the actual amount of omega 3 fatty acids, detectable levels of mercury, PCB's and dioxins, and the overall purity level of the fish oil.

The IFOS publishes a report showing these test results and grades the oils on specific criteria. A fish oil receiving 5 Stars is said to be a high quality pharmaceutical-grade fish oil.

The criteria used by the IFOS to determine if a product is pharmaceutical-grade are:

• Must contain minimum 60% EPA and DHA concentrations.
• Oxidation levels must be less than the 75% standard set forth by the Council of Responsible Nutrition (CRN).
• PCB levels must less than 50% of the CRN standard.
• Dioxin and Furan Levels less Than 50% of World Health Organization Standard.

Additional criteria used to classify pharmaceutical-grade fish oils are:

• Must be made according to "pharmaceutical standards" that ensures the oil is free of environmental contaminants, heavy metals, lipid peroxides, and other harmful substances.
• Ratio of omega-3 fatty acids to arachidonic acid must be greater than 50:1.
• Must contain an optimal amount of natural vitamin E as a preservative.
• Must be manufactured in a facility that's been certified Good Manufacturing Practices (cGMP) which is approved for pharmaceutical products.

Some manufacturers will claim their fish oil is pharmaceutical-grade. But remember there's no federal regulation on any claims made about the purity of fish oils without reliable testing.

The IFOS is a third-party testing company that doesn't receive compensation from fish oil companies so their results are reliable and unbiased.

Fish oils not listed on the IFOS website may be pharmaceutical-grade, but you'll have no way of validating the manufacturer's claims without scientific testing.

Why You Should Use Pharmaceutical Fish Oils

These high potency fish oils will give you greater amounts of omega 3 fatty acids and less impurities than cheap oils. These qualities will help you achieve the health benefits you seek from these powerful marine oils.

Lower quality oils may not give you the same results as pharmaceutical-grade fish oils and may contain rancid oils (due to oxidation) that may cause upset stomach, gas and bloating.

Pharmaceutical-grade fish oils will cost more due to the more stringent manufacturing procedures not found in lower grade oils.
