The Claim
All 20 omega-3 supplements tested in France met the Global Organization for EPA and DHA Omega-3s (GOED) standards for oxidative status, with peroxide values below 5 mEq O₂/kg, p-anisidine values below 20, and Totox values below 26, indicating no detectable oxidative degradation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
All 20 omega-3 supplements tested in France met established international quality standards for oxidative stability, with measured levels of oxidation markers below defined safety thresholds.
See the scientific wording
All 20 omega-3 supplements tested in France complied with the Global Organization for EPA and DHA Omega-3s (GOED) standards for oxidative status, with peroxide values below 5 mEq O₂/kg, p-anisidine values below 20, and Totox values below 26, indicating no detectable oxidative degradation.
Omega-3 oils are protected from air, light, and heat during production and stored in sealed containers with antioxidants, which stops the chemical breakdown that causes rancidity.
What the research says
1 studyStudy: Assessment of Lipid Quality in Commercial Omega-3 Supplements Sold in the French Market
Scientists tested 20 omega-3 supplements sold in France and found that all of them were fresh and not spoiled, meeting the global safety rules for oxidation. So yes, none were rancid.
