The Best Ways to Store Fish Oil

Fish oil contains important omega-3 fatty acids such as eicopentaenoic acid and docosahexaenoic acid. These fatty acids provide the body with many benefits such as reducing inflammation, helping prevent Alzheimer’s and Parkinson’s, and even possibly reducing cancer risks. While the name would imply fish oil is produced by fish, it is actually accumulated in their bodies from eating microalgae which produce the oil. Here are some ways to properly store your fish oil supplements.

• Purchase your fish oil supplement in small quantities, preferably a month’s supply at a time. This will decrease the amount of time the bottle is open and will keep your fish oil fresher than opening a bottle that would last a year. Date the bottle when you open it and carefully inspect the fish oil before you take it to ensure that it is still good.


• If you wish to increase the shelf life of your fish oil, try freezing it. This will prevent the fish oil from being exposed to high temperatures and humidity which can cause spoilage to occur at a faster rate. Just make sure the type of fish oil you purchase can be frozen safely. Likewise, the refrigerator is also an option to keep the supplement in a cool environment.


• Store your fish oil away from any light or put it in a dark container. Light can cause the oil to undergo oxidative rancidity, a reaction that can be triggered by sunlight. 


• Keep the supplement in an airtight container. This will decrease the amount of oxygen which is available, which can also help prevent oxidative rancidity from occurring.

If your fish oil begins to have a rancid odor, this is a sign that it may have spoiled. Another sign of spoilage is discoloration of the gel capsules. If you notice any signs of spoilage, do not take the supplements.
