How long is omega 3 good past expiration date?

Omega-3 supplements can remain effective for a few months past their expiration date if stored properly in a cool, dark place. However, their potency and freshness may diminish over time, and they can develop an unpleasant odor or taste if rancid. It's always best to check for signs of spoilage, such as off smells or changes in appearance, and to consult a healthcare professional if unsure about their safety. When in doubt, it's safer to replace expired supplements.
