Can You Put Omega 3 Fish Oil in the Freezer?

The health kits of many homes had fish oils in them, with some people keeping extra bottles in their cupboards.

If it’s in a warm environment, keeping it this way will shorten its shelf life.

That is the reason why some people use freezing as a method of storing things. We searched the internet to find out if freezing makes the fish oil last longer.

It’s possible to put a whole bottle of Omega 3 fish oil supplement in the freezer without negatively affecting its quality. 

The fish oil’s foul burps and the fishy aftertaste can be lessened by freezing it. 

The possibility of an upset stomach that affects some people who take fish oil may be decreased by freezing the fish oil.

Fish oil can be rancid in a short period. You need to be very careful about when, where, and how you store it.

We are going to dive into how freezing is the best preservation method for keeping Omega 3 fish oil safe.

How Can I Store Omega-3 Capsules?

Omega-3 fish oil has a shelf life of less than a year. However, knowing just that isn’t enough. What causes healthy oil to go bad fast is something we need to understand.

Omega-3 fish oil is high in reactivity to oxygen, which makes it go bad quickly. The fish oil is made up of unstable multiple bonds.

The rancid smell associated with fish oil is caused by the oxidation process that happens when these molecules are exposed to oxygen.

The bicycle that was left out in the open is a concrete example of this process. Over time, it becomes rusty and dull due to its continuous exposure to the elements.

If you expose fish oil to air or oxygen, it will go bad fast. This is the reason why high-quality fish oil is hard to find.

Most of the fish oils you see in stores are already oxidation-prone. We suggest that you do the fish oil storage hacks after you purchase one.

Use zip-lock bags

Zip lock bags are an effective way to store Omega 3 fish oil. The capsule should be transferred to the bag after opening the bottle.

Put excess air from the bag in the fridge or freezer by using a vacuum seal or the water vacuum seal method.

You can extend the shelf life of the fish oil by further slowing down the oxidation.

Keep away from heat or direct sunlight

If you choose to leave fish oil at room temperature, you should use a specialized container to store it.

The sunlight or heat mustn’t reach them. When exposed to direct sunlight, fish oils become unstable in the heat and can go bad very quickly.

Store in a cool environment

The majority of fish oils are in capsule or gel forms. This is an attempt by the fish oil manufacturer to slow the oxidation process.

It doesn’t mean you should put all your faith in the capsule to keep the fish oil fresh. You should always store fish oil in a dark place, especially in liquid form.

There is no better place to store fish oil than the fridge or freezer. The cool temperature in the fridge or freezer helps in slowing down oxidation.

If you follow the next storage hack, then it is safe to leave fish oils in gel forms on the counter or cupboard. It’s safer to put them in the fridge because it makes them last longer.

What Happens When You Freeze Fish Oil?

The most effective way to store fish oil is through freezing since the storage options have been taken care of.

When you put the fish oil in the freezer, it will become cloudy and not solid.

Unlike other oils, fish oil can be frozen at -47.2 degrees Fahrenheit or -44 degrees Celsius, which is way lower than -18 degrees Fahrenheit, the lowest temperature most chest freezers can get.

It’s easier to swallow the fish oil capsule after it’s been frozen. The chance of having a foul breath after taking a frozen fish oil capsule is lowered by the fact that they get slowly digested in the stomach.

After taking fish oil, taking fish oils that have been frozen can decrease a taker’s likelihood of having a bad experience.

Some fish oil consumers and manufacturers use freezing to check their purity. The belief is that pure and high-quality fish oil does not become cloudy when frozen.

Although it holds some truth, this is not the sole factor. It is not possible to determine if the fish oil is high quality by freezing alone.

Slowing down the oxidation process is the only role that freezing can play. There is no better time to do this than now. Nothing more.

Is It Possible That Freezing Destroys Omega-3?

While freezing prolongs shelf life, it can cause the Omega 3 content of fish oils to lose some of their effectiveness.

According to the National Fisheries Institute, this loss is only a small one.

If you are patronizing fish oils to get a full dose of the heart-healthy Omega 3, we suggest that you only store them in the fridge or your cupboard.

It’s a good idea to keep an eye on the expiration date.

What Is the Life of Fish Oil in the Freezer?

After their manufacturing date, a fish oil capsule’s lifespan is typically 24 months. The only thing that applies is when the bottle remains sealed.

The instant you open the bottle, the fish oil oxidizes and spoils. Fish oils can be kept in the freezer for up to one year if they are stored correctly.

Even if the fish oils are stored in the fridge or freezer, experts recommend consuming them within 30 to 90 days after opening their bottle.

Even though fish oils are highly susceptible to oxidation, they can still be purchased with a fish oil supplement.

Even though it was frozen, the short consumption time frame was still there.

Accidentally consuming expired fish oil can cause a range of symptoms, from indigestion to urinary tract infections.

Is It Possible That Fish Oil Go Bad If Not Refrigerated?

It’s not a good idea to put fish oil in the cupboard, the refrigerator, or the freezer.

Once fish oils get exposed to air, oxidation is an ongoing process and you can only do so much to make it last.

Focus on the ways you can safely consume fish oils, instead of worrying about variables outside of your control.

It is possible to label the bottle with the date it was opened and the expected expiration date, which is 30 days after opening.

You should abandon the idea of buying in bulk as fish oils can quickly spoil. You should buy them in small amounts and store them in a cool and dry place.

It’s important to keep it away from direct sunlight exposure and other forms of light for a long time.

If you buy fish oils in the malls outside the box, it’s a good idea to watch out for oxidation because it may already be bad.
