Fish oil is an omega-3 fatty acid supplement that has been linked to a number of health benefits.

In fact, studies show that fish oil can help reduce inflammation, improve heart health, protect brain function, and promote proper growth and development (1).

Additionally, taking your fish oil supplement at certain times can help optimize its effectiveness and prevent certain side effects.

This article takes a closer look at when you should take fish oil.

You can take fish oil at any time of the day, depending on when it is best for you.

This is because most research suggests that the potential benefits of fish oil supplements are not immediate, but rather related to long-term use (2).

Studies show that taking fish oil for weeks, months, or even years can increase the levels of omega-3 fatty acids in the blood (3, 4).

However, adjusting the timing of supplementation can help avoid some of the side effects associated with fish oil.

For example, acid reflux is one of the most common side effects associated with fish oil supplements.

While this could be due to the fat content of fish oil, the ingested oil floating on the stomach contents likely contributes to this side effect (5, 6, 7).

Breaking your fish oil into two smaller doses and taking them morning and evening is an effective strategy that can help prevent acid reflux and indigestion (7).


Since most of the benefits of fish oil are associated with long-term use, you can take it at any time of the day. That said, breaking your supplement into two smaller doses in the morning and at night can reduce acid reflux.

Regardless of when you take your fish oil supplement, it’s important to take it with a meal to maximize its absorption into the body.

In particular, consuming fish oil with a good source of fat can increase the bioavailability of omega-3 fatty acids and improve their effectiveness (8, 9).

Additionally, ingesting fish oil with your diet may reduce certain side effects associated with the supplement.

For example, consuming fish oil immediately before a meal can reduce the risk of acid reflux and indigestion (7).

Although more research is needed, some users also report that ingesting fish oil with their diet can often prevent other side effects such as diarrhea, belching, and nausea.


Ingesting fish oil with food can increase your omega-3 fatty acid intake and reduce certain side effects such as acid reflux, diarrhea, belching, and nausea.

Finding a time that works for you and consistently taking your fish oil supplement is key to maximizing its potential benefits.

For some, taking it first thing in the morning is the easiest way to make sure you are getting your daily dose.

In the meantime, others may find that taking fish oil at lunch or just before bed works better for them.

For this reason, it’s best to find out what works for you and establish a routine for optimizing potential health benefits.


By setting a routine and using your supplement consistently, you can maximize the potential health benefits.

Since the potential benefits of fish oil are tied to long-term use, consistently consuming fish oil is more important than the time of day you ingest it.

However, ingesting fish oil with food can increase absorption and prevent certain side effects.

Finding a time that works for you and consuming fish oil regularly is the easiest way to optimize its effectiveness.

If you want to try fish oil to improve your overall health, you can find various products in stores and on-line.

Discuss any new preparation with your doctor first, especially if you have an underlying medical condition.
