A recent study by the Global Organization for EPA and DHA Omega-3s (GOED) tested the quality of 48 of the top-selling EPA / DHA omega-3 supplements in the United States. The quality was determined by testing the EPA / DHA content of the products and comparing the content indicated on the bottle.

The results showed that of the 42 products with label contents, all met US requirements by containing at least 80% of the labeled content. Of the 42 products, 40.5% (17 products) had an EPA / DHA content between 80 and 100% of the labeled content, 57.1% had between 100 and 110.4% of the labeled content and 1% contained 138.7 % of the labeled EPA / DHA content.

The products were also tested for compliance with the oxidation parameters. This was a challenge as there are no regulatory limits for the quality of primary or secondary oxidation for EPA / DHA supplements in the US. However, based on strict industry and relevant pharmacopoeia quality standards, 89.5% of the 48 products tested were found to be compliant.

Although the results were positive overall, GOED admits that there is still room for improvement.
