Introduction
Do fish oil capsules expire? Most fish oil products have a shelf life of approximately 24 months from the date of manufacture, provided they remain unopened and are stored properly. Exposure to heat, light, or air can accelerate the oxidation process, shortening their usability. Once opened, the capsules’ freshness may decline faster, so storing them in a cool, dark place, like a refrigerator, is recommended. Always check the expiration date on the packaging and inspect for signs of rancidity, such as a strong odor or bitter taste, to ensure safety and effectiveness.
What Is Fish Oil, and Why Does It Expire?
Fish oil is a dietary supplement derived from the tissues of fatty fish such as salmon, mackerel, and sardines. It is rich in omega-3 fatty acids, particularly EPA and DHA, which are essential for heart health, brain function, and reducing inflammation. Fish oil is commonly consumed in capsule or liquid form and is prized for its potential to support overall well-being.
Like all oils, fish oil is susceptible to oxidation, which is the process where the oil reacts with oxygen, leading to the breakdown of its molecular structure. This degradation results in the oil becoming rancid, with an unpleasant odor and taste. The omega-3 fatty acids in fish oil are particularly prone to oxidation because they are polyunsaturated fats, making them less stable than saturated fats.
Fish oil capsules can expire due to several factors, such as exposure to heat, light, and air, which accelerate the oxidation process. If the capsules are not stored correctly—in a cool, dark place or preferably in a refrigerator—they can lose their potency more quickly. Over time, the beneficial effects of the omega-3 fatty acids diminish, and consuming expired fish oil can lead to unpleasant side effects, such as digestive issues or a fishy aftertaste. Always check the expiration date and store fish oil properly to maintain its quality.

Identifying spoilage and its potential risks
Food spoilage occurs due to various factors affecting its quality and safety. Chemical reactions, like oxidation, can alter nutrients and flavors, while physical changes, such as moisture loss, impact texture.
