Can EPA and DHA Help With Sleep?
We all know how important sleep is. It helps the body recover, keeps the mind sharp, and supports overall health. But what happens when sleep becomes elusive, no matter how hard you try? If you’ve been struggling to get enough rest, you may have heard that EPA and DHA, types of omega-3 fatty acids, could be the answer. But can these nutrients actually help improve sleep?
Why Sleep Matters
Before we dive into EPA and DHA, it’s important to understand just how essential sleep is. Sleep isn't just about resting. It’s when the body repairs itself, when memories are solidified, and when the immune system gets a boost. Consistently good sleep has been linked to better mood, improved memory, and a lower risk of chronic diseases like heart disease, diabetes, and even cancer.
However, sleep doesn’t always come easy for everyone. So, can EPA and DHA help us out here?
What Are EPA and DHA?
To understand how EPA and DHA can help with sleep, you first need to know what they are. Both are types of omega-3 fatty acids, which are essential nutrients that our bodies cannot produce on their own. This means we need to get them from food or supplements.
- DHA (Docosahexaenoic acid) is primarily found in the brain and retina, where it plays a critical role in brain function and vision.
- EPA (Eicosapentaenoic acid), on the other hand, is known for its anti-inflammatory properties and benefits to heart health.
How EPA and DHA helps with your sleep
Now, let’s get into the science of how EPA and DHA might help with sleep.
-
EPA and DHA and Sleep Hormones
One of the most important ways EPA and DHA affect sleep is through their influence on sleep hormones. Melatonin is a hormone produced by the pineal gland that signals to the body when it’s time to wind down and prepare for sleep. If melatonin levels are out of balance, sleep can be disrupted.
Studies show that omega-3s, particularly DHA, can support the regulation of melatonin production. When EPA and DHA are present in adequate amounts, melatonin is better able to do its job, leading to improved sleep cycles and more restful sleep.
-
EPA and DHA and Stress Reduction
Stress is one of the biggest culprits behind sleepless nights. When you’re stressed, the body releases cortisol, a hormone that prepares you for the “fight or flight” response. But when cortisol levels remain high, sleep quality suffers.
Luckily, EPA and DHA have been shown to help with stress. A 2017 study found that people who consumed EPA and DHA had lower levels of anxiety and stress, leading to improved sleep quality.

Impact on Sleep Disorders
For people with sleep disorders, like insomnia or sleep apnea, getting a good night’s sleep can feel like a distant dream. But here’s where EPA and DHA may come in handy.
A study on children with ADHD found that omega-3 supplementation helped reduce sleep disruptions. This suggests that EPA and DHA could be particularly helpful for individuals who have trouble sleeping due to other health conditions.
How to Incorporate More EPA and DHA Into Your Diet
If you’re convinced that EPA and DHA could help improve your sleep, the next step is to figure out how to get more of these omega-3s into your routine. Here’s how:
-
Eating Omega-3 Rich Foods
The best way to get EPA and DHA is through food. Here are some top sources of omega-3s:
- Fatty Fish: Salmon, mackerel, sardines, and anchovies are excellent sources of EPA and DHA.
- Chia Seeds: While chia seeds are higher in ALA (a plant-based omega-3), they can still help boost your omega-3 intake.
- Flaxseeds: Like chia seeds, flaxseeds are another great source of ALA. They are not as rich in EPA and DHA but are still beneficial for overall omega-3 consumption.
-
Omega-3 Supplements
If eating fatty fish isn’t your thing, omega-3 supplements are an easy alternative. Fish oil supplements are the most common, but there are also plant-based supplements, like algae oil, which is an excellent source of DHA for vegetarians and vegans.
Omega-3 supplements typically come in the form of capsules or liquids. Look for supplements that list both EPA and DHA in the ingredients. The dosage depends on your needs, but a good starting point is around 1,000 milligrams of combined EPA and DHA per day.
How Much EPA and DHA Should You Take?
If you’re new to omega-3 supplementation, you might wonder how much EPA and DHA is enough. While it varies by individual, most studies suggest that consuming at least 1,000 milligrams of combined EPA and DHA per day can provide benefits for sleep, mood, and general health.
Other Tips for Better Sleep
Here are a few tips to help make sure you’re setting yourself up for better sleep:
-
Create a Sleep Friendly Environment
- Keep your bedroom dark and quiet.
- Use comfortable pillows and blankets.
- Set a consistent sleep schedule by going to bed and waking up at the same time every day.
-
Practice Relaxation Techniques
- Try deep breathing exercises.
- Consider gentle yoga or stretching before bed.
- Meditate to calm your mind and reduce stress.
-
Limit Screen Time Before Bed
Avoid looking at your phone, tablet, or computer for at least an hour before bed. The blue light emitted by screens can interfere with melatonin production.
Are There Any Side Effects to EPA and DHA?
EPA and DHA are generally safe to consume, whether through food or supplements. However, like anything, it’s important not to overdo it. Excessive amounts of omega-3s can lead to mild side effects like fishy burps, upset stomach, or an increased risk of bleeding, especially if you’re taking blood-thinning medications.
It’s always a good idea to talk to a healthcare provider before starting new supplements, especially if you have any underlying conditions or take medications regularly.
Wrapping It Up
Incorporating more EPA and DHA into your diet through omega-3 foods and supplements could be a helpful step toward improving sleep quality. While EPA and DHA alone might not be a cure for sleep disorders, they have the potential to enhance sleep patterns by supporting healthy hormone regulation, reducing stress, and promoting better brain health.
