LabDoor analyzed 30 best-selling fish oil supplements in the United States, measuring total omega-3 content, EPA and DHA quantities, vitamin D and CLA amounts, methylmercury concentration, and total oxidation values.
21/30 products demonstrated omega-3 levels that varied by over 10% off their label claims, 15 of which recorded a 25% variance between actual versus claimed content. EPA + DHA content also showed significant ingredient variance, ranging from -50.7% to +90.2% versus its stated label claims.
Every product contained measurable amounts of mercury, with 3 products recording 50% or greater of the allowable mercury content per serving. The majority of products passed oxidation (freshness) assays, although 1 product recorded a TOTOX score above the upper limit and 6 more products measured within 5% of the upper limit.
