DHA is an essential brain food that boosts neurotransmission, cognition, memory, learning, reduces brain inflammation, assists in the repair of and helps grow new brain cells.

DHA (docosahexaenoic acid) is an omega-3 fatty acid. DHA is crucial for the healthy structure and function of your brain at all ages.

DHA impacts your brain’s signaling systems, neurotransmitters, memory, learning, focus and attention. It helps reduce and even repair cognitive decline.

The best algae-sourced DHA on the market today is Performance Lab® Omega-3 which contains 600 mg of DHA and 300 mg of EPA per dose.

The famous Framingham Heart Study followed-up with 899 men and women who were free of dementia. Subjects had a median age of 76 years. And were followed for 9.1 years for the development of dementia and Alzheimer’s Disease.

Results from the study showed 99 new cases of dementia including 71 of Alzheimer’s. The researchers concluded that those with the highest levels of DHA were “associated with a significant 47% reduction in the risk of developing all-cause dementia”.[i]

DHA helps:

  • BDNF. Brain-derived neurotrophic factor (BDNF) is your brain’s growth hormone. DHA has the ability to turn on your brain’s BDNF.
  • Neuroplasticity. DHA helps your brain build new neural pathways. Critical for maintaining a healthy brain. And optimizing neural signaling and cognition.
  • Neuroprotection. DHA acts as an anti-inflammatory by reducing the enzyme COX-2. Inflammation is a key factor in both Alzheimer’s and Parkinson’s Disease. And in every other neurodegenerative disease.

Overview

DHA (docosahexaenoic acid) is an omega-3 fatty acid. Your brain is made up of 60% fat. And much of that fat is DHA.

Your body does not make DHA on its own. So you must get it from food or a supplement. And if you are a vegan, you are at serious risk of a life-threatening DHA deficiency.

Foods that are rich in DHA include fish, fish oil, Krill and other crustaceans, and algae.

But fish do not make DHA. Fish and other marine predators get it from smaller fish and crustaceans that feed on algae. It’s algae that has the enzymes to produce DHA that we need to remain healthy.

The best algae-sourced DHA on the market today is Performance Lab® Omega-3 which contains 600 mg of DHA and 300 mg of EPA per dose.

DHA from eggs and some dairy products only supply about 20 mg of DHA per day.

DHA is essential for maintaining brain health, memory and learning functions. DHA reduces brain inflammation, stimulates new nerve cell growth, and assists in brain cell repair.

DHA is critical for brain health

How does DHA Work in the Brain?

Your brain is composed of 60% fat. 15 – 20% of your cerebral cortex is DHA. Even the retina in your eyes is 30 – 60% DHA. Making DHA the most essential nutrient for eye and brain health.

The highest levels of DHA are found in phosphatidylserine (PS) and phosphatidylethanolamine (PE).[ii] Lower levels are found in phosphatidylcholine (PC).

PS makes up about 70% of neuron tissue mass. It helps in the storage, release and activity of neurotransmitters and receptors.

PC also makes up part of the neuron tissue mass. And helps in maintaining cell structure, fat metabolism, neuron signaling and the activation of a number of enzymes.

And PE is part of neuron cell membranes. PE is involved in cellular signaling.

PS, PE and PC are called phospholipids. Together they alter the fluidity of cell membranes. Changing the fluidity of cell membranes alters their permeability and protein activity. And influences cellular signaling.

Made up largely of DHA, these cellular membranes regulate entry into the cell, and control neuroreceptor function. Which facilitates cellular communication between, and within cells.

DHA also reduces inflammation by regulating proteins and enzymes within cells. And boosts the production of anti-inflammatory compounds that protect cells.

DHA maintains the activity of certain enzymes that control electrical signaling between cells. And it regulates the brain cell concentration of PS which is vital for cell survival.

And DHA regulates calcium oscillations, which are involved in neurotransmitter release, mitochondrial function, gene activation, oxidative stress and brain cell development and growth (BDNF).

DHA vs. EPA: What’s the Difference?

Most medical authorities and scientists agree that Omega-3 oils are important for good health. Omega-3s boost brain function, decrease inflammation, reduce the incidence of fatal heart attacks and strokes, help autoimmune diseases and improve vision.

Omega-3 from fishWe have general agreement about the health benefits of Omega-3 oils. But few appreciate the difference between DHA (docosahexaeonic acid) and EPA (eico-sapentaenoic acid).

The ratio of DHA and EPA varies a lot in commercial Omega-3 supplements. Most have higher concentrations of EPA to DHA. Mainly because it’s cheaper to manufacture, and has less of a fishy odor.

But studies show that most of the brain health benefits of Omega-3’s are derived from DHA rather than EPA.

One study in Chicago followed 815 residents from 1993 – 2000. Study subjects were between 65 and 94 years. 131 study participants developed Alzheimer’s Disease. Those who ate fish at least once a week had a 60% less risk of Alzheimer’s compared to those who didn’t eat fish.

Researchers found that it was the intake of DHA rather than EPA that reduced the risk factor in getting Alzheimer’s. EPA made no difference whatsoever.[iii]

How Things Go Bad

From reviewing the “How does DHA Work in the Brain” section of this article, you can imagine that when things go bad with DHA – they go really bad.

Fish and marine oil supplements like krill oil are a source of DHA and EPA because they get it from algae. Plants contain another Omega-3 called alpha-linolenic acid (ALA).

Technically ALA can be converted to DHA and EPA. But most modern humans lack the ability to convert plant sources of Omega-3s into all the DHA our brain needs.

When we don’t get enough DHA, we experience:

↓ Problems with attention, learning and memory

↑ Depression, anxiety, aggression, anger, suicide risk

↑ Bipolar disorder, Alzheimer’s Disease and Schizophrenia

Not having adequate levels of DHA in the brain cause things to break down. If the inadequate intake of DHA goes on for a while, disease starts to set in. Including neurodegenerative diseases like Alzheimer’s and cancer.

DHA benefits

DHA makes up much of the gray matter in your brain. It’s an integral part of cell membranes and their function.

Your brain is 60% fat. And a large part of that is DHA.

The good news is; degenerative conditions can not only be prevented by adding DHA to your nootropic stack. It can also be reversed.

DHA for a healthy brain

In one study, researchers worked with 485 elderly subjects with memory problems. They saw significant improvement with those taking 900 mg of DHA per day for 24 weeks compared to the control group.[iv]

In another double-blind, placebo-controlled trial, scientists worked with 49 women aged 60 – 80 years. One group received 800 mg per day of DHA for 4 months.

Researchers found those using DHA had a significant improvement in verbal fluency scores. And an improvement in memory and learning.[v]

How does DHA feel?

Chances are when you start using DHA you won’t feel it. There’s no profound stimulant feeling.

But if you suffer from chronic depression, within a few weeks you should feel the depression lift.

After supplementing with DHA for a while your cognition will be better. You’ll think clearer and quicker. Your memory and ability to learn will improve. And you’ll likely have more energy and motivation.

But it is very likely you won’t think to attribute these improvements to adding DHA to your stack. Something else will get the credit.

DHA Clinical Research

DHA is crucial for an optimally functioning brain. The goal of every neurohacker. DHA impacts your brain’s structure, signaling systems, neurotransmitters, memory, learning, focus and attention.

We have decades of clinical research verifying the importance of DHA in your nootropic stack. And several books have been written on the subject in the last couple of years. Here’s just a snippet of what’s available…

DHA Reduces Hostility and Anger

In a study with 41 university students in Japan, scientists compared a high-DHA diet (1.5 grams/day) with placebo. This was recorded over 3 months to see the effects on hostile responses.

The researchers found a 27% incidence of hostile answers in the placebo group when nothing extraordinary was going on. And hostile responses rose to 92% during final exams.

There was no increase in hostility among those taking a DHA supplement. These guys even found DHA supplementation significantly reduced hostility among university staff.[vi]

DHA Restores Neurotransmitters & Memory

As your brain ages, there is an increase in membrane rigidity. This causes changes in synapses resulting in a decrease in transmitter release. Long-term potentiation is affected which impairs the development of memories.

Several studies have shown that DHA can support healthy levels of these neurotransmitters. In one study with aged rats, researchers restored neurotransmitter release in the hippocampus. And reversed age-related memory problems.

Adding omega-3 fatty acids to the rat’s feed for 8 weeks raised concentrations of DHA in the rat’s brain. And actually reversed age-related memory impairment.[vii]

DHA Improves Attention & Learning

DHA also has an effect on neurotransmitters serotonin, norepinephrine, acetylcholine, glutamate and dopamine. Deficiencies in DHA have been shown to lower levels of dopamine. Resulting in problems with attention and learning.[viii]

DHA even plays a role in neurotransmitter receptor function. DHA affects brain cell membrane structures including neuroreceptors.[ix]

Some of these receptors communicate inside cells when stimulated by glutamate, serotonin and acetylcholine.[x] The numbers of these receptors can be increased by you, by adding DHA to your nootropic stack.

So if you are using nootropics that affect things like acetylcholine, serotonin, dopamine and serotonin in your brain. It would be wise to add DHA to your nootropic stack. And ensure you get the most bang for your investment in nootropics.

DHA Recommended Dosage

Recommended daily dosage of DHA is 1,000 mg.

Fish oil supplements vary in ratios of DHA to EPA. Salmon naturally contain more DHA than EPA. A supplement from algae may contain only DHA.

Krill oil provides both DHA and EPA. So read the labels. And whatever supplement you get, make sure you end up with at least 1,000 mg of DHA.

And recall that fish and krill do not produce DHA on their own. Marine life get their DHA from algae in the wild.

Most brands of fish oil have been proven safe, and free of mercury. And do not contain unsafe levels of PCB’s (polychlorinated biphenyls).

To further avoid the contaminants in an unrefined supplement, choose a fish oil or Omega-3 supplement made from small, oily fish like anchovies, sardines or menhaden. And check the labels carefully for purity.

Ideally, get one of a few supplements now available that are pure, refined DHA. With lower or minimal amounts of EPA.

DHA Side Effects

Fish oil capsules commonly have both DHA and EPA. Capsules with EPA are not recommended for infants or small children. Because they upset the balance between DHA and EPA during early development. This also applies to pregnant women.

Fish oil could cause minor side effects like loose stools, upset stomach and belching.

Fish oil may lower blood pressure. So if you already take a medication to lower blood pressure, make sure you talk to your doctor first.

If you’re supplement contains EPA, it could interact with blood thinners and increase bleeding. Same is true for aspirin. But this is not true of DHA. DHA-only supplements do not thin the blood.

Fish oil supplements may lower blood sugar levels. So be careful if you’re on diabetes medications.

Omega-3 fatty acids may reduce some of the side effects of cyclosporine which is used to stop rejection after an organ transplant.

Type of DHA to Buy

Performance Lab® Omega-3 DHA is available as a supplement in two forms:

  • Fish oil or Omega-3 capsules. Which usually have both DHA and EPA. Most Omega-3 supplements contain higher amounts of EPA compared to DHA. But for our purposes, and to support cognitive health, we need an Omega-3 supplement containing higher amounts of DHA to EPA.
  • DHA from fish oil. Some supplement manufacturers now offer capsules containing higher amounts of pure, refined DHA. And reduced amounts of EPA. Our brains require 1,000 mg DHA per day. So look for a DHA supplement that provides 1,000 mg DHA in 2-3 gelcaps.
  • DHA from algae. Which may or may not contain EPA and is vegetarian friendly. Algae is the natural source of these Omega-3s in the wild and where fish and other marine life get their Omega-3s.

For as little as $49/month you can experience better cognition, memory and mood simply by using a daily DHA supplement. My favorite is Performance Lab® Omega-3 which contains 600 mg of DHA and 300 mg of EPA per dose.

Performance Lab® Omega-3 contains life’s™ OMEGA algae oil which supplies natural triglyceride Omega-3s that are 70% more bioavailable than synthetic ethyl esters used in cheaper and lower quality Omega-3 fish oil supplements.

Performance Lab® Omega-3 is delivered in NutriGels which are vegan, carrageenan-free softgels. No fishy smell or aftertaste and easy on your digestive system.

Nootropics Expert Recommendation

DHA (Omega-3) 1,000 mg per day.

Nootropics Expert Tested and ApprovedI recommend using DHA as a nootropic supplement.

Your body does not make DHA on its own. So you must get it from food. Or take it as a supplement.

DHA is one of the most important nootropics you can add to your stack. Your brain is 60% fat. And much of that fat is DHA.

DHA is critical for brain cell repair and regeneration (neurogenesis). And it is an integral part of neural signaling. Both between neurons as well as inside brain cells.

DHA has an effect on critical neurotransmitters and neuroreceptors. It is a powerful anti-inflammatory. And is involved in neuroplasticity.

Hundreds of studies on Omega-3s and DHA show benefits in preventing and even reversing neurodegenerative disease.

It’s best if you find a supplement that contains twice as much DHA than EPA. Such as Performance Lab® Omega-3. And you can safely take 1,000 mg of DHA per day.

Hi David Tomen,

Will DHA help for my next problems:

I am very bothered by forgetfulness and difficulty learning.
Will it help with my studies? And career and so on.

so that’s why I bought this product:

Carlson labs Elite DHA

Thank you very much,

Greetings,

Hi David Tomen,

I have read your article, have a question for you. What happens if you take in around 2200 mg of DHA? is it too much?

Greetings,

Murat

    David Tomen
    March 1, 2018

    Murat, you should be fine with 2,200 mg of DHA. Worst that could happen is listed in the “side effects” section of this review.

      Murat

      David Tomen,

      Okey thanks for your information.

I have been taking nordic natural fish oil which has total of 970mg dha & *400 mg eha. I feel tired with a slight headache. I actually felt better with the nordic natural that had only 450mg dha. I don’t understand why I feel worse with more dha???

    David Tomen
    November 13, 2017

    James, great question and impossible to answer. DHA affects so many things in our brain including cells, neuroreceptors, and neurotransmitters. Is sounds like more DHA threw something out of balance in your brain. Go back to what works and mark this one off as an experiment. I do appreciate your report because someone else may experience something like this. And wonder if they were the only one. So thank you.

      Murat
      March 1, 2018

      Hi Mr. David Tomen,

      I have read your article, what happens if you ingest more than 1000 mg dha per day? for example if you take 2200 mg? I do not like capsules so that’s why I take a drink.

      Thanks in advance,

      Greetings,

      Murat

        David Tomen
        March 1, 2018

        Murat, you should be OK with 2200 mg. But it depends on how your body responds to that dose. Some natural health practitioners recommend higher doses than 1,000 mg. Please read the “side effects” section of this post for possible issues.

Barb W.

Hi David, the extra DHA upset my tummy when I took it
with my regular fish oil. Should I break them up a bit?
Barb

    David Tomen
    September 22, 2017

    Barb, you can divide your dose throughout the day. Or you could see if you really need the other fish oil supplement your currently using. Either way, dividing doses throughout the day is always a good idea. But anything that has a stimulant-type reaction should be used before noon.

I just started taking Carlson’s Super DHA, 3 per day, and I am amazed at the results! I immediately noticed a mood boost, clearer thinking and my eyesight became noticeably sharper! I won’t pretend to be immune to a placebo effect, but I am virtually certain the effects are real.
What do you think? Is is considered possible to get such results virtually overnight?

    David Tomen
    August 30, 2016

    It’s a very real possibly to get rapid results from therapeutic doses of DHA Joseph. Many are surprised at how DHA affects vision. The rods and cones of the retina are rich in DHA. So supplemental DHA directly affects photoreceptor activity of retinal cells. DHA is directly involved in boosting BDNF which helps new neural networks develop for learning and memory. DHA also has an effect on the neurotransmitters serotonin, norepinephrine, acetylcholine, glutamate and dopamine. Affecting mood, cognition and memory. Thanks for sharing your experience with DHA. Hopefully more will see this and add DHA to their stack.

which pure DHA product do you take?

    David Tomen
    August 27, 2016

    I use Nature’s Way EfaGold Mega-DHA which has 1,000 mg of DHA per 2 capsules. Or Carlson Super DHA which also has 1,000 mg of DHA per 2 capsules. Both companies have a good reputation for purity. Both are regularly tested by 3rd party labs for heavy metals and other toxins.

Joseph thorpe
July 29, 2016

I have been taking Nordic Naturals DHA, which has 480mg of Dha and 205mg per 2 capsules and I take 4 a day. Is this 2/1 ratio clearly inferior to a pure DHA fish oil? Why is it better to use a pure DHA product? Does the EPA interfere with the efficacy of the DHA? If there is a compelling rationale to switch to a pure DHA I will happily do so!

    David Tomen
    July 29, 2016

    I don’t think a combined DHA and EPA supplement is “inferior” Joseph. But our bodies convert DHA to EPA as needed. So I choose to supplement with pure DHA. This is typically a more expensive option but not absolutely necessary. As long as you’re getting 1000 mg of DHA per day.

      Steven
      May 14, 2019

      I cannot find any info that our bodies convert DHA into EPA as needed. Can you confirm where you got this information?

        David Tomen
        May 14, 2019

        Steven, our bodies do NOT convert DHA into EPA and it’s nowhere in this review.

        Technically alpha-linolenic acid (ALA) from plants can be converted to DHA and EPA. But us modern humans do not do this conversion process efficiently enough for it to be useful. Which is the reason why we use an Omega-3 supplement.

Joseph thorpe
July 29, 2016

What is your opinion of fish oil “experts” who claim that you can only process around 4mg of Dha a day and that it it has a very long half life, if I recall correctly, up to a year? These same “experts” of course recommend a very high epa fish oil.

    David Tomen
    July 29, 2016

    In my humble opinion, they are NOT fish oil experts Joseph. Your brain is made up of about 60% fat. Most of it is DHA and is found primarily in the gray matter in your brain. And assigning a “half-life” to DHA doesn’t make much sense to me considering that it’s permanently part of my brain. And if there’s not enough I die.

    Dr. David Perlmutter who wrote “Brain Maker” and who is an expert on brain and cognitive health recommends 1000 mg of DHA daily. It’s what I use and I can feel the difference. If I miss supplementing with DHA for 3 days, my thinking in not nearly as fluid. And things just feel off somehow.

    Our bodies use EPA to improve blood flow and improve overall brain function. But our bodies convert DHA to EPA naturally (http://www.ncbi.nlm.nih.gov/pubmed/9076673). So to me, it makes more sense to supplement with pure DHA.
