Why should you take omega-3 at night?


Omega-3 fatty acids are incredibly important for overall health. They provide many benefits for your heart, brain, eyes and more.

Many people take omega-3 supplements to increase their intake of these beneficial fats. But when is the best time to take them - morning or night?

Here's a detailed look at why taking omega-3 at night may be advantageous.

Why should you take omega-3 at night?

What Are Omega-3s?

Before exploring when to take omega-3s, let's briefly go over what they are and why they're so important.

Omega-3s are polyunsaturated fatty acids. There are three main types:

  • Eicosapentaenoic acid (EPA): Mainly found in fish and seafood. Provides anti-inflammatory effects.
  • Docosahexaenoic acid (DHA): Also found in seafood. Important for brain and eye health.
  • Alpha-linolenic acid (ALA): Found in plant oils like flaxseed. The body can convert ALA to EPA and DHA, but only in small amounts.

These omega-3 fats provide many health benefits, including:

  • Reduced inflammation
  • Lower triglycerides
  • Improved heart health
  • Enhanced brain function and mental health
  • Better eye health
  • Healthier skin and hair

However, most people don't get enough omega-3s from their diets. Taking supplements can help fill this nutritional gap.

Now let's look at why nighttime may be the optimal time to take your omega-3 supplement.

Why Take Omega-3s at Night?

Here are some of the main reasons why taking your omega-3 supplement in the evening may be beneficial:

1. Symptoms of Omega-3 Deficiency Worsen at Night

Omega-3s help regulate inflammation, mood and circulation. Deficiencies in these fats can cause symptoms like joint pain, depression and poor blood flow to become worse at night.

Taking an omega-3 supplement before bed may help relieve these overnight symptoms.

For example, if joint pain flares up at night, omega-3s can help reduce inflammation and discomfort. They also promote better sleep, which is important for pain management.

Additionally, omega-3s enhance blood flow by making blood cells more flexible and blood vessels dilated. This may alleviate nighttime leg cramps and restless legs caused by poor circulation.

2. Omega-3s May Enhance Overnight Heart Benefits

Heart rate and blood pressure dip during sleep. Omega-3s help optimize these overnight heart rhythms by their effects on the nervous system.

Studies show omega-3s also significantly lower heart rate and improve heart rate variability. These benefits are enhanced when omega-3s are taken in the evening.

By optimizing heart health at night, omega-3s may protect against nocturnal cardiac events, like heart attacks and strokes while you sleep.

3. May Support Overnight Metabolic Functions

Omega-3s have beneficial effects on energy balance and metabolism. Research shows taking them at night may amplify these effects.

In one study, omega-3 supplements at bedtime helped increase overnight lipolysis - the breakdown of fat for energy. They also improved insulin sensitivity in the morning.

These overnight metabolic effects may promote weight loss. In another study, taking omega-3s before bed increased feelings of fullness the next morning and decreased calorie intake.

4. Promotes Better Sleep Quality

Getting good sleep is crucial for overall wellbeing. Unfortunately, many adults don't get the recommended 7-9 hours of sleep per night.

Omega-3s have been shown to improve several aspects of sleep. DHA, in particular, increases melatonin and promotes deeper, more restorative sleep.

In studies of children and adults, taking an omega-3 supplement at bedtime consistently improved sleep quality, reduced the time to fall asleep and increased sleep duration.

Better sleep regulates hormones, enhances brain function and improves focus, memory and mood the next day.

5. May Support Brain Function Overnight

The brain stays active while you sleep, consolidating memories, clearing out toxins and more. Omega-3s support these overnight brain functions.

DHA makes up over 90% of omega-3s in the brain. It helps form cell membranes and facilitates communication between brain cells.

Supplementing with DHA enhances oxygen delivery to the brain, provides neurons with energy and supports the regeneration of brain cells overnight.

By optimizing overnight brain cell repair and connections, omega-3s promote focus, learning, mood and memory the next day.

6. Convenient Dosing Schedule

Taking any supplement at night helps make it part of your bedtime routine. This can improve compliance compared to morning dosing.

Omega-3s are best absorbed with a meal containing fat or oil. For most people, dinner tends to be the heaviest meal and fat intake for the day.

Taking omega-3s along with dinner allows them to digest and absorb optimally. Fatty acids also have a natural mild sedative effect, which can promote sleepiness.

Overall, taking omega-3 supplements at night is easy to remember and effective.

How Much and What Kind of Omega-3 to Take at Night

To enjoy the full overnight benefits of omega-3s:

  • Take 1-2 grams of total omega-3s - Look for a supplement with both DHA and EPA. A ratio of 2:1 EPA to DHA is ideal.
  • Time it with dinner - Take your supplement during your final meal to improve absorption.
  • Choose a quality product - Look for reputable third-party testing and purity guarantees. Fish oil and algal oil omega-3s are both good options.
  • Talk to your doctor - Get personalized advice on the right omega-3 dosage and formulation for your needs.

Any Downsides to Taking Omega-3s at Night?

Omega-3 supplements are generally very safe. The most common side effect is a fishy aftertaste, especially with fish oil products.

There is little evidence of significant downsides to taking omega-3s at night. However, a few things to keep in mind:

  • Omega-3s may intensify vivid dreams or nightmares in some people. This can usually be resolved by reducing your dosage.
  • Very high doses may contribute to blood thinning. Consult your doctor if taking blood thinners or before surgery.
  • Pay attention to any changes in sleep quality. Omega-3s should improve sleep, but can cause insomnia in rare cases.

As with any supplement, it's wise to start with a low dose and work your way up to assess your individual tolerance.

Conclusion: Why Take Omega-3s at Night

Research increasingly supports taking omega-3 supplements in the evening to enhance their broad health benefits.

The main reasons to take omega-3s at night include:

  • Relieving inflammation, pain, low mood and poor circulation overnight
  • Optimizing heart health while you sleep
  • Providing metabolic and weight loss benefits
  • Promoting deeper, more restorative sleep
  • Supporting brain function and repair overnight

Simply making omega-3s part of your bedtime routine improves compliance. Fatty acids are also well absorbed with a heavy dinner containing fat or oils.

Given the multitude of overnight benefits, take your omega-3 supplement as the last thing you ingest before bed. This simple habit ensures you wake up feeling healthier, happier, sharper and more refreshed.
