Your Complete Guide to IFOS Fish Oils

IFOS Fish Oils

Zone Labs Omega Rx is an IFOS Fish Oil

What are exactly are IFOS Fish Oils and why would you want to buy them?  IFOS fish oils are ultra high-grade fish oil supplements that have been tested to meet very strict standards of purity and quality.

The IFOS is actually an acronym which stands for International Fish Oils Standards.

It’s operated by an independent Canadian company called Nutrasource that tests products for purity and their omega 3 fatty acid concentrations.

If you own a nutritional supplement company that makes fish oils, you can submit your product to Nutrasource and they’ll test your product for omega 3 concentrations and purity levels.

There is a fee to have the testing done and the results are made available to the public called the 5 Star Ratings Report.

What I like about IFOS fish oils is you can visit the company website to see if the item you bought has been tested by the IFOS and you can also see the actual results for certain batches of product that were tested.



Get Your 5 Star Rating Fish Oil Right Here!

The most popular reports from the IFOS are their 5 Star Ratings Reports.

This category is used to test ultra-refined, high-concentrated oils that contain a minimum 60 percent of combined eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

A product oil is given ‘5 Stars’ if it meets criteria in five specific areas:

Star 1 – Product Passes all CRN/WHO Testing Categories

Star 2 – Product Tests show Minimum 60% EPA plus DHA combined concentration

Star 3 – Oxidation Level less than 75% of CRN Standard

Star 4 – PCB Levels less than 50% of CRN Standard

Star 5 – Dioxin and Furan Levels less than 50% of WHO Standard

The CRN/WHO standards are actually set forth by the CRN (Council for Responsible Nutrition) and WHO (World Health Organization).

The 5 Star Rating is further classified as follows:

  • 5 Star – Exceptional Product Batch
  • 4 Star – Very Good Batch
  • 3 Star – Good Batch
  • 2 Star – Fair Batch
  • 1 Star – Poor Batch

So if you use this rating system, you should know that these ratings apply only to a particular batch of products that were actually tested for each corresponding brand.

You should be aware that not all manufacturers will test every single batch in their inventory.

The best way is to think of these ratings is to imagine if you’re standing along the assembly line and testing the occasional bottle to assure purity.

Unfortunately, the whole industry isn’t government regulated in all countries and manufacturers don’t have to publish poor test results of certain batches.
