Tag: Omega 3 aftertaste

Did you know that a high-quality, fresh omega-3 oil should not have a strong, fishy taste? While many people assume this is a normal characteristic, an unpleasant fishy flavor is actually a key sign that the oil has gone rancid due to oxidation.

According to one 2022 analysis, some flavored omega-3 fish oil supplements exceeded acceptable oxidation levels by over 68%. The truth is, high-quality, fresh omega-3 vitamins should not taste like fish. A strong, fishy taste or aftertaste is a key indicator of rancidity, which can reduce the supplement's effectiveness and is often masked by flavorings.

According to a 2022 analysis, some fish oil supplements contained oxidation levels up to 11 times higher than recommended limits, directly contributing to a fishy aftertaste. This unpleasant side effect raises the question: does omega-3 have an aftertaste, and is it always a sign of a problem?
