Tag: Fish oil shelf life

According to a 2023 study referenced by BodyBio, as much as 45% of fish oil supplements may be rancid by the time they reach consumers. This surprising statistic highlights a critical issue: the high perishability of fish oil, even when protected within capsules. While many assume the gelatin coating provides indefinite protection, environmental factors can cause the beneficial omega-3 fatty acids to degrade over time, compromising quality and potency.

According to the USDA, properly strained and refrigerated used frying oil can be safely stored for up to three months. However, when it comes to used fish oil, the lifespan is often much shorter due to its high polyunsaturated fat content, which is prone to oxidation. Understanding proper storage and knowing the signs of spoilage is crucial for both flavor and health.
