what are the real differences between epa and dha

Is DHA better than EPA?

While both are beneficial, you may want to consider the unique properties of each to address different aspects of health. EPA has anti-inflammatory effects while DHA is known for boosting brain health. DHA stands for docosahexaenoic acid and EPA stands for eicosapentaenoic acid.

What exactly are EPA and DHA, really?

EPA and DHA stand for eicosapentaenoic acid and docosahexaenoic acid respectively. These fatty acids are omega-3 fats, which are found in cold water fish. EPA DHA are highly unsaturated fats because they contain six and five double bonds on their long structural chains. These polyunsaturated fats play a very important role with the function of ...

Is EPA more important than DHA?

Summary: DHA may be more effective at reducing chronic inflammation than EPA. The omega-3 fatty acids EPA and DHA work differently against chronic inflammation, according to the results of a small randomized study, suggesting each has its own important role to play in regulating the immune system.

Is DHA better for cardiovascular care than EPA?

When evaluating how EPA and DHA affect one another, they found that higher DHA blunts the benefit of EPA. In particular, they also found that those patients with higher levels of DHA than EPA, were more at risk for heart problems. Le said that these results raise further concerns about the use of combined EPA/DHA, particularly through supplements.

Is it better to have more EPA or DHA?

A new study that measured omega-3s in people's blood found that high levels of EPA were associated with a lower risk of cardiovascular events, whereas DHA appeared to counter the beneficial effects of EPA. The findings suggest that combining EPA and DHA in a supplement may void any potential benefits for heart health.

Which is better for inflammation EPA or DHA?

The results showed that DHA had a stronger anti-inflammatory effect than EPA: DHA lowered the genetic expression of four types of pro-inflammatory proteins, whereas EPA lowered only one type. DHA lowered white blood cell secretion of three types of pro-inflammatory proteins, whereas EPA lowered only one type.

What is the best ratio of DHA to EPA?

Stephen Kopecky recommends a 3:2 ratio of either EPA to DHA or vice-versa. According to the research reviewed here, DHA outperforms EPA in reducing total triglyceride counts and increasing HDL (good) cholesterol. Alternatively, EPA has a more beneficial effect on lowering overall LDL (bad) cholesterol.

Do EPA and DHA compete for absorption?

EPA is an inhibitor of the enzyme delta-5-desaturase (D5D) that produces AA, whereas DHA is not. The more EPA you have in the diet, the less AA you produce because both fatty acids compete for the same enzymes required to make eicosanoids. DHA does not compete for those enzymes.

Do you need both EPA and DHA?

EPA and DHA do different things, so you need them both, especially for the brain. If your goal is reducing cellular inflammation, then you probably need more EPA than DHA.

Should I take EPA and DHA separately?

Wong cited a recent study that had pooled data from 17 studies and had found that higher circulating levels of EPA and DHA, both taken separately and together, were associated with a lower risk of premature death and death from cardiovascular disease.

Is 1000mg of omega-3 too much?

Too much omega-3 can be harmful The Food and Drug Administration (FDA) claims that omega-3 supplements containing EPA and DHA are safe if doses don't exceed 3,000 mg per day. On the other hand, the European Food Safety Authority (EFSA) notes that up to 5,000 mg per day from supplements is safe.

Is EPA or DHA better for anxiety?

For both anxiety and depression, you want more EPA than DHA. For depression, the research points to the most benefit coming from a ratio of about 60% EPA to DHA. Then you need around 1000 mg/day of EPA.

Is EPA or DHA better for cholesterol?

When compared with each other, DHA resulted in a significantly greater increase in HDL cholesterol and a greater decrease in triglycerides than EPA, although this latter difference did not reach statistical significance [49].

Is EPA or DHA better for dry eyes?

The Omega-3 fatty acids EPA and DHA have the most potent health benefits and are the most important in controlling the inflammation related to dry eyes. Specifically, a high EPA to DHA ratio may be most beneficial for dry eyes.

Is EPA or DHA better for depression?

Clinical evidence indicated that eicosapentaenoic acid (EPA) was more effective than docosahexaenoic acid (DHA) in depression treatment.

What are the symptoms of lack of omega-3?

Symptoms of omega-3 fatty acid deficiency include fatigue, poor memory, dry skin, heart problems, mood swings or depression, and poor circulation. It is important to have the proper ratio of omega-3 and omega-6 (another essential fatty acid) in the diet.

Which omega is best for inflammation?

A healthy diet contains a balance of omega-3 and omega-6 fatty acids. Omega-3 fatty acids help reduce inflammation, and some omega-6 fatty acids tend to promote inflammation. In fact, some studies suggest that elevated intakes of omega-6 fatty acids may play a role in complex regional pain syndrome.

Which omega-3 is best for inflammation?

DHA is more effective at reducing inflammation than EPA, but both have a role. All of these effects makes fish oil potentially beneficial for people with arthritis. EPA and DHA come with other health benefits: They can help prevent heart attacks by making it harder for blood to clot.

Does EPA reduce inflammation?

EPA and DHA, plentiful in fish and shellfish, have, in some studies, been linked to lower risk of heart disease and are believed to work by reducing inflammation.

How much DHA should I take for inflammation?

Fish Oil Dosage Matters Research has consistently shown that at least 2000 mg of EPA/DHA daily may be necessary for anti-inflammatory effects (7, 8, 9).

Why is DHA not an inhibitor of EPA?

DHA is not an inhibitor of this enzyme because it can’t fit into the active catalytic site of the enzyme due to its larger spatial size. As an additional insurance policy, EPA also competes with AA for the enzyme phospholipase A2 necessary to release AA from the membrane phospholipids (where it is stored). Inhibition of this enzyme is the mechanism of action used by corticosteroids. If you have adequate levels of EPA to compete with AA (i.e. a low AA/EPA ratio), you can realize many of the benefits of corticosteroids but without their side effects. That’s because if you don’t release AA from the cell membrane, you can’t make inflammatory eicosanoids.

What is EPA in the diet?

EPA is an inhibitor of the enzyme delta-5-desaturase (D5D) that produces AA. The more EPA you have in the diet, the less AA you produce. This essentially chokes off the supply of AA necessary for the production of pro-inflammatory eicosanoids (prostaglandins, thromboxanes, leukotrienes, etc.)

Why is EPA important?

The ultimate goal of using omega-3 fatty acids is the reduction of cellular inflammation. Since eicosanoids derived from arachidonic acid (AA), an omega-6 fatty acid, are the primary mediators of cellular inflammation, EPA is the most important of the omega-3 fatty acids to reduce cellular inflammation for a number of reasons.

Why is DHA important for the retina?

This increase in membrane fluidity is critical for synaptic vesicles and the retina of the eye because it allows receptors to rotate more effectively, thus increasing the transmission of signals from the surface of the membrane to the interior of the nerve cells . This is why DHA is a critical component of these parts of the nerves. On the other hand, the myelin membrane is essentially an insulator so that relatively little DHA is found in that part of the membrane.

How to find out how much fish oil you need?

How much more? The most effective way to find out how much fish oil you need is to test your blood. Our Cellular Inflammation Test Kit allows you to test your personal levels at home. You will receive a detailed report with your AA and EPA levels, as well as your Cellular Inflammation Score, and personalized wellness recommendations. Then, you will never need to guess how much fish oil you should take.

Does DHA affect cellular inflammation?

This makes DHA a poor substrate for these key inflammatory enzymes. Thus DHA again has little effect on cellular inflammation, whereas EPA can have a powerful impact. Finally, it is often assumed since there are not high levels of EPA in the brain, that it is not important for neurological function.

Is DHA a good competitor for EPA?

Because of its increased spatial dimensions, DHA is not a good competitor of phospholipase A2 relative to EPA. On the other hand, EPA and AA are very similar spatially so they are in constant competition for the phospholipase A2 enzyme, just as both fatty acids are in constant competition for the delta-5 desaturase enzyme. This is why measuring the AA/EPA ratio is such a powerful predictor of the state of cellular inflammation in your body.

Where do EPA and DHA come from?

EPA and DHA both naturally occur in fatty cold-water fish such as salmon, mackerel or anchovies. They are also present in the small crustacean called krill that can be processed into krill oil.

Where is DHA concentrated?

Is especially concentrated in the grey matter of the brain and the rod outer segments of the retina.

What are the different omega-3 fatty acids?

Omega-3 fatty acids are a specific type of fat that has a lot of health benefits for your body and mind! They are part of our cell membrane and are essential for our body. This means, that we are not able to produce them in our metabolism but that we need to consume them through food or supplements like fish oil or krill oil.

What is the only plant based omega-3 fatty acid?

ALA is the only plant based omega-3 fatty acid out of the three named above. It naturally occurs in plants like specific types of algae for example. Other food sources are plant oils like flaxseed, soybean or canola oils.

Why is DHA important for infants?

DHA has been shown to play an important role in childhood cognitive development. Because supports the healthy development of the brain and eye in foetus, infant and throughout early childhood it is especially important for pregnant and breastfeeding mothers to watch their DHA intake.

Why is fish oil important?

DHA is an important building block in the brain cells. It improves how fluid and flexible neurons are and improves communication between them. Overall brain function improves when the neurons are healthier and communicate well with each other. DHA may therefore boost brain health and a high DHA content in your fish oil supplement can support issues such as depression, mood swings, bipolar symptoms or poor memory.

Can you get ALA from fish oil?

ALA is an essential fatty acid, which means that our body cannot generate it itself but we need to get it from the foods we eat. Our body can convert some ALA into EPA and DHA, but only in very small amounts. This is why consuming EPA and DHA directly through food or dietary supplements like fish oil or krill oil can be more practical and an easy way to increase your omega-3 intake.

EPA benefits

One of the most popular uses of omega-3 is for the purpose of reducing inflammation, and in this regard, EPA is the more effective omega-3.

DHA benefits

Though EPA is the star when it comes to reduction of inflammation, DHA is necessary for physiological function, and has its own exclusive host of benefits.

The Bottom Line

Both types of omega-3 are necessary for the maintenance of physiological function, though they both differ in their structure and effects on the body.

What is the difference between EPA and DHA?

Eicosapentaenoic acid (EPA) is one of the main types of omega-3 fatty acids and contribute to cognitive development. Docosahexaenoic acid (DHA) is one of the three main types of omega-3 fatty acids, and play a beneficial role in brain function and eye health. When combined in adequate doses, EPA & DHA provide the body with a multitude ...

What is EPA in the body?

Eicosapentaenoic acid (EPA) is one of the main types of omega-3 fatty acids, with a range of applications in the management of numerous health conditions. Along with DHA, EPA belongs to the group of the most abundant fatty acids in the brain and the retina, and it is necessary for optimal brain development and nervous functions.

How much EPA is in vegan omega 3?

Amandean’s Vegan Omega-3 supplement includes 300mg DHA + 150mg EPA for optimized levels of these valuable fatty acids. When purchasing an omega-3 supplement, make sure to study the ingredient list and pay special attention to the EPA & DHA content, as it is what determines the quality of this product at the end of the day.

What are the two classes of Omega 3 fatty acids?

Omega-3 fatty acids belong to the group of polyunsaturated fatty acids, simply referred to as PUFAs. All PUFAs, including their two predominant classes - omega-3 and omega-6, consist of long carbon- atom chains. What makes PUFAs stand out, in particular, is that they have at least two double bonds between carbons in their chain. Both omega-3 and omega-6 fatty acids have important roles in the structure of cell membranes, acting as a source of energy and precursors to bioactive lipid mediators. Yet another mutual characteristic between these two categories of PUFAs is that they’re considered essential nutrients - meaning that the body cannot manufacture them from scratch.

What does DHA do to a child?

What’s more, DHA levels can determine numerous brain functions and cognitive processes in a child, including attention, problem-solving, as well as social, emotional, and behavioral development. According to a study conducted by C. Agostoni and colleagues, a DHA deficiency at an early age can be linked to cognitive issues and disorders, such as learning disabilities.

Where is DHA found?

DHA is mostly present in the membranes of cells, and it has a rather significant structural role. In addition, DHA is one of the main elements of cellular communication.

Can you convert EPA to DHA?

Yes, our body is able to convert EPA to DHA. However, the amount of DHA received through this conversion process is minimal. This is why it’s important to choose an Omega-3 supplement that contains both EPA and DHA. Speaking of conversion rates, ALA can be converted into EPA, but once again, the results are almost negligible. As far as ALA is concerned, it cannot be manufactured via conversion and it must therefore be obtained through dietary sources.

Omega-3S at A Glance

• There are 11 differentomega-3 fatty acids, but the majority of all scientific research on omega-3 fatty acidshas only centered around three. They are ALA, EPA, and DHA. Omega-3s are considered essential fatty acids. When a fatty acid or other nutrient is essential, it means our bodies need it to thrive and function properly, but can’t make it on th...
