Omega-3 Explained: EPA vs DHA, Heart, Brain & Vision Benefits – and What Makes a High-Purity Fish Oil Different?

Omega-3 fatty acids are among the most widely recognised nutrients in everyday nutrition, but choosing an Omega-3 supplement can quickly become confusing.

Should you look at the amount of fish oil, the amount of total Omega-3, or specifically the levels of EPA and DHA? Does the EPA:DHA ratio matter? And what does “high-purity fish oil” actually mean?

These questions are particularly relevant when looking at concentrated formulas such as EnzOmega® 700 mg, which provides 700 mg Omega-3 fatty acids per capsule, including 400 mg EPA and 200 mg DHA.

This guide explains what EPA and DHA do, how to read an Omega-3 label and what to consider when choosing a fish oil supplement.


What Are Omega-3 Fatty Acids?

Omega-3 fatty acids are a family of polyunsaturated fatty acids.

The three names you will encounter most frequently are:

ALA – Alpha-Linolenic Acid

Primarily found in plant foods such as flaxseed, chia seeds and walnuts.

EPA – Eicosapentaenoic Acid

A long-chain Omega-3 fatty acid found primarily in marine sources.

DHA – Docosahexaenoic Acid

Another important long-chain marine Omega-3 fatty acid.

Although all three belong to the Omega-3 family, ALA is not the same as EPA or DHA.

The body can convert some ALA into EPA and DHA, but they remain nutritionally distinct. Fish oil and algae oil are therefore commonly used when the goal is to obtain EPA and DHA directly.


EPA vs DHA: What Is the Difference?

EPA and DHA are often listed together, but they are not identical.

Both have recognised physiological functions, while DHA has additional established roles of its own.

❤️ EPA + DHA and Normal Heart Function

EPA and DHA contribute to:

The Normal Function of the Heart

The beneficial effect is obtained with a daily intake of at least:

250 mg EPA + DHA

One EnzOmega® capsule provides 600 mg EPA + DHA, consisting of 400 mg EPA and 200 mg DHA.


🧠 DHA and Normal Brain Function

DHA contributes to:

The Maintenance of Normal Brain Function

For this beneficial effect, the required daily intake is:

250 mg DHA

This point is especially important when comparing Omega-3 supplements.

A product may contain a large amount of “fish oil” or even total Omega-3 without necessarily providing 250 mg DHA.

The manufacturer's current information for EnzOmega® confirms that DHA's beneficial effect on normal brain function is obtained with a daily intake of 250 mg DHA.

Because one EnzOmega® capsule provides 200 mg DHA, two capsules provide 400 mg DHA, exceeding the 250 mg DHA level associated with this beneficial effect.


👁️ DHA and Normal Vision

DHA also contributes to:

The Maintenance of Normal Vision

Again, the beneficial effect is obtained with a daily intake of:

250 mg DHA

This means DHA has recognised nutritional roles relating to both normal brain function and normal vision.


Fish Oil Is Not the Same as Omega-3

This is one of the most important things to understand when shopping for an Omega-3 supplement.

Imagine two products both say:

“1,000 mg Fish Oil”

That does not necessarily mean they provide the same amount of Omega-3.

Fish oil is the source material. EPA and DHA are specific Omega-3 fatty acids contained within that oil.

A better label comparison therefore looks at:

Total Omega-3 → EPA → DHA

rather than simply comparing the total amount of fish oil.


How Much Omega-3 Does EnzOmega® Provide?

EnzOmega® is designed as a concentrated marine Omega-3 formula.

Each capsule provides:

Omega-3 Component Per Capsule
Total Omega-3 Fatty Acids 700 mg
EPA 400 mg
DHA 200 mg
EPA + DHA 600 mg
EPA:DHA Ratio 2:1

The product is available in a 60-capsule pack under PZN 03960657.

The manufacturer's recommended intake is 1–2 capsules daily, taken whole directly before or with a meal and sufficient liquid.

That provides:

Daily Intake Total Omega-3 EPA DHA
1 Capsule 700 mg 400 mg 200 mg
2 Capsules 1,400 mg 800 mg 400 mg

What Does a 2:1 EPA:DHA Ratio Mean?

EnzOmega® provides EPA and DHA in a:

2:1 Ratio

In practical terms, that means the formula contains approximately twice as much EPA as DHA:

400 mg EPA : 200 mg DHA

The manufacturer describes this as a physiological EPA:DHA ratio.

However, a ratio should never be considered in isolation.

When comparing products, it is generally more informative to look at the actual milligrams of EPA and DHA delivered by the recommended daily serving.

For example, a product can advertise an attractive EPA:DHA ratio while providing relatively small absolute quantities of both fatty acids.


Why Does Fish Source Matter?

The source of the fish oil is another factor worth considering.

According to the manufacturer, EnzOmega® uses fish oil concentrate obtained from wild small cold-water ocean fish, particularly:

Anchovies

and

Sardines

The manufacturer specifically highlights the use of small wild marine fish and its controlled purification process as quality characteristics of the product.

The current ingredient declaration identifies the fish oil concentrate as coming from anchovies and sardines.


What Does “High-Purity Fish Oil” Mean?

Fish oil quality is not determined only by EPA and DHA concentration.

Purification is also important because marine oils require careful processing and quality control.

The manufacturer describes EnzOmega® as a highly purified fish oil concentrate produced using a controlled vacuum distillation process. It states that the oil is tested and purified with regard to contaminants such as heavy metals.

This is one of the reasons why simply comparing the number of milligrams on two Omega-3 bottles does not provide the whole picture.

When evaluating fish oil, it can be useful to consider:

EPA and DHA concentration, fish source, purification process, quality controls and complete ingredient composition.


Why Is Vitamin E Added to Fish Oil?

Omega-3 fatty acids are polyunsaturated fats and are susceptible to oxidation.

The current EnzOmega® ingredient list includes vitamin E, together with rosemary extract.

In this formulation, vitamin E serves as part of the oil-protection system rather than turning EnzOmega® into a conventional vitamin E supplement.


What Is Actually Inside an EnzOmega® Capsule?

The current ingredient declaration lists:

Fish Oil Concentrate (67.7%) from Anchovies and Sardines, Vitamin E, Rosemary Extract, Gelatin, Humectant: Glycerin, Water.

Because the capsule contains fish oil and gelatin:

EnzOmega® is not vegan or vegetarian.

It contains fish as an allergen.

The current product information also identifies the formula as free from milk protein, lactose, gluten, yeast, soy and added colourings.


Fish Oil vs Algae Oil: Which Should You Choose?

Fish oil is not the only direct dietary source of EPA and DHA available in supplement form.

Fish oil provides marine EPA and DHA derived from fish.

Algae oil can provide DHA and, depending on the formula, EPA without using fish.

For people following a vegan diet or avoiding fish, algae-derived Omega-3 can therefore be a useful alternative.

For consumers who are comfortable with marine fish oil, products such as EnzOmega® offer concentrated EPA and DHA in relatively few capsules.

Neither source should be judged simply by whether it is “fish” or “algae.” The actual amounts of EPA, DHA and total Omega-3 per recommended daily serving remain important comparison points.


How Much EPA and DHA Should You Look For?

There is no single number that makes one Omega-3 supplement automatically suitable for everyone.

For general nutritional comparison, however, the authorised health-claim thresholds provide useful context:

❤️ Normal Heart Function

250 mg EPA + DHA daily

🧠 Normal Brain Function

250 mg DHA daily

👁️ Normal Vision

250 mg DHA daily

These amounts refer to the conditions required to obtain the respective beneficial effects; they are not a universal prescription for every person's individual nutritional needs.

This also illustrates why reading EPA and DHA separately is useful.


One Capsule or Two?

The manufacturer recommends:

1–2 Capsules Daily

One capsule provides:

700 mg total Omega-3
400 mg EPA
200 mg DHA

Two capsules provide:

1,400 mg total Omega-3
800 mg EPA
400 mg DHA

At one capsule, the combined 600 mg EPA + DHA exceeds the 250 mg daily amount associated with the beneficial effect on normal heart function.

At two capsules, the 400 mg DHA exceeds the 250 mg daily amount associated with DHA's beneficial effects on normal brain function and normal vision.


When Should You Take Omega-3?

The manufacturer's recommendation for EnzOmega® is:

Take 1–2 capsules daily, whole, directly before or with a meal and sufficient liquid.

This makes it easy to integrate Omega-3 into an existing meal routine.

Consistency and following the recommended intake are more relevant than trying to identify a particular “perfect” hour of the day.


Who Might Consider an Omega-3 Supplement?

People who regularly eat oily fish may already obtain meaningful amounts of EPA and DHA through their diet.

Others may eat fish only occasionally or not at all.

An Omega-3 supplement can provide a convenient and measurable way to complement dietary intake of EPA and DHA when desired.

It should still be considered a supplement to the diet, rather than a substitute for a varied and balanced diet and healthy lifestyle.


What Should You Look for When Buying Omega-3?

Instead of choosing based only on the largest number printed on the front of the package, check the complete label.

Five particularly useful questions are:

  1. How much total Omega-3 is provided?
  2. How many milligrams of EPA are provided?
  3. How many milligrams of DHA are provided?
  4. What is the source of the oil?
  5. How is the oil purified and protected from oxidation?

EnzOmega® makes these values relatively transparent, with 700 mg total Omega-3, including 400 mg EPA and 200 mg DHA per capsule, plus information about its fish source and purification process.

Is EnzOmega® a Medicine?

No.

EnzOmega® is a:

Food Supplement

It is intended to supplement dietary intake of Omega-3 fatty acids and should not be described as treating or preventing cardiovascular, neurological, eye or other diseases.

The appropriate nutritional claims relate specifically to EPA and DHA's recognised physiological functions.


Important Information

Do not exceed the recommended daily intake.

Food supplements should not be used as a substitute for a varied, balanced diet and healthy lifestyle.

Keep out of reach of young children and follow the storage instructions on the original packaging.

If you take medication – particularly medication affecting blood clotting – or have a medical condition, discuss Omega-3 supplementation with an appropriate healthcare professional.

Always refer to the current product packaging for the latest ingredient, allergen, dosage and safety information.


Final Thoughts: What Makes a Good Omega-3 Supplement?

When comparing Omega-3 supplements, “fish oil” and “Omega-3” should not be treated as interchangeable numbers.

EPA and DHA are the figures that tell you much more about what a marine Omega-3 supplement actually provides.

EnzOmega® offers a concentrated formula with:

700 mg Total Omega-3 per Capsule

400 mg EPA

200 mg DHA

600 mg EPA + DHA

2:1 EPA:DHA Ratio

It combines these amounts with fish oil sourced from small wild cold-water ocean fish and a controlled purification process.

For anyone comparing Omega-3 supplements, checking EPA, DHA, total Omega-3, source and purification is a much more informative approach than looking at fish-oil milligrams alone.
