The Maths Trap: Why Your Daily Omega 3 Intake Is Probably Too Low

We’ve all heard the advice.

Eat more oily fish. Take a fish oil. Get more Omega 3.

It’s one of the few nutrition tips that never seems to go out of fashion. No matter the trend, Omega 3 always survives.

And yet, for something so widely recommended, most people still aren’t getting enough.

Even people who think they are.

You might eat fish occasionally. You might take a capsule every morning. You might even buy a “high strength” bottle from the supermarket.

But your omega 3 daily intake is still likely lower than you realise.

Not because you’re doing anything wrong.

Because the maths is quietly working against you.

Why Omega 3 Is One of the Few Supplements Everyone Agrees On

Omega 3 fats are classed as “essential”.

That word matters.

Essential means your body can’t make them on its own. You have to get them from food or supplements.

Omega 3 plays a role in everyday background jobs your body carries out constantly. It supports normal heart function. It supports brain and nervous system function. It also supports normal vision.

Nothing dramatic. Nothing instant.

Just systems quietly doing what they’re meant to do.

That’s also why Omega 3 rarely gives you a big “wow” feeling. When it’s working properly, you often don’t notice it at all. You just feel steady.

And that’s exactly why so many people assume it isn’t doing anything.

“I Take Omega 3… But I Feel Nothing”

This is one of the most common things we hear.

People say they’ve taken fish oil for years. They don’t feel any different. Some stop taking it and notice no change.

That usually leads to one of two conclusions.

Either Omega 3 doesn’t work for them. Or supplements are pointless.

In most cases, neither is true.

The issue is almost always dose and concentration, not biology.

You’re taking something. You’re just not taking enough of the right thing.

The Big Misunderstanding: Fish Oil vs Omega 3

This is where the maths trap really begins.

Most products don’t actually sell you “Omega 3”.

They sell you fish oil.

Fish oil is just the carrier. Omega 3 is what’s inside it.

The active parts you care about are two fatty acids called EPA and DHA.

These are the components linked to Omega 3’s recognised benefits.

Here’s the problem.

A capsule can say “1000mg Fish Oil” on the front, while only containing a small amount of EPA and DHA on the back label.

The rest is just neutral fat.

So you think you’re taking 1000mg of Omega 3.

In reality, your omega 3 daily intake might only be a fraction of that.

Why Front Labels Are So Misleading

Supplement labels aren’t lying. They’re just selective.

“1000mg Fish Oil” sounds impressive. But unless you turn the bottle around and read the small print, you have no idea how much Omega 3 you’re actually getting.

It’s a bit like buying orange juice that’s mostly water.

Still juice. Just not very effective.

This is why two people can both “take Omega 3” and have completely different experiences. One is hitting meaningful levels. The other is swallowing filler oil.

The NHS Baseline Most People Miss

In the UK, the NHS gives a clear guideline.

Adults should aim for at least 250mg of combined EPA and DHA per day.

That’s not a high-performance target. It’s the baseline. The minimum to support normal function.

If your supplement doesn’t hit that number in a normal daily dose, your omega 3 daily intake is technically under target.

Many supermarket brands only reach this level if you take multiple capsules per day. Most people don’t.

The “One Capsule” Assumption

Another quiet trap is assuming one capsule equals one dose.

Many brands define a “serving” as two, three, or even four capsules.

So when the front label says “high strength”, the back label often tells a different story.

That bottle you thought would last a month suddenly runs out in a week. And your intake still isn’t what you thought it was.

Why Plant Omega 3 Rarely Solves the Problem

Some people try to avoid this by using plant sources instead.

Flaxseed, chia seeds, and walnuts contain a type of Omega 3 called ALA.

ALA isn’t useless. But your body has to convert it into EPA and DHA before it can be used properly.

That conversion process is inefficient for many adults. Only a small percentage gets converted.

So even with a plant-heavy diet, your omega 3 daily intake of usable EPA and DHA may still be low.

That’s why oily fish and fish oil remain the most reliable sources.

Real Food vs Real Life

In a perfect world, we’d all eat oily fish twice a week.

Salmon. Mackerel. Sardines. Trout.

That’s the NHS recommendation.

But real life gets in the way.

Fish goes off quickly. It smells. Kids complain. Work takes over.

Supplements exist to bridge that gap.

The problem is choosing one that actually does.

The Concentration Rule That Changes Everything

Here’s the simplest rule that cuts through the confusion.

Ignore the front of the label.

Look at the EPA and DHA numbers on the back.

Add them together. Then compare that total to the overall oil amount.

If EPA and DHA make up less than half of the oil, it’s a low-concentration product. Most of what you’re swallowing isn’t doing much.

Higher-quality Omega 3 supplements usually hit at least 50% concentration.

Some go further.

That’s where the maths finally starts working in your favour.

Why Cheap Omega 3 Often Costs More

Low-concentration oils look cheaper at first glance.

But they force you into higher capsule counts.

Six capsules a day. Eight capsules a day. Sometimes more.

That bottle you thought would last weeks disappears quickly.

You end up paying more over time, swallowing more capsules, and often dealing with side effects like fishy burps.

The Fishy Burp Test

Fishy burps aren’t “normal”.

They’re often a sign of oxidised oil or poor processing.

High-quality Omega 3 oils are purified and stabilised properly. They should be easy to take and easy to forget about.

No aftertaste. No repeat appearances.

Why Intake Advice Varies by Country

You might notice different Omega 3 numbers online.

That’s because recommendations vary.

In the UK, 250mg of EPA and DHA is the baseline. In the US, many guidelines suggest a daily range of 250–500mg for healthy adults.

Not as a treatment. Just as sensible daily support.

Higher-concentration oils make it easier to reach these levels without increasing capsule count.

EPA and DHA: Why Balance Matters

EPA and DHA aren’t identical.

DHA plays a major role in brain and nervous system structure. EPA supports other aspects of everyday wellbeing.

For most people, a balanced oil that provides both makes the most sense.

Extreme formulas usually complicate things without improving consistency.

Why Fortified Foods Don’t Move the Needle

You’ll see Omega 3 added to eggs, spreads, yoghurts, and cereals.

The amounts are usually small.

They’re fine as a bonus, but they’re not enough to rely on for your omega 3 daily intake.

The Real Issue Isn’t Knowledge. It’s Maths.

Most people already know Omega 3 matters.

What they don’t realise is how little they’re actually getting.

They trust the front label. They assume one capsule is enough. They never check EPA and DHA.

So they take it for months or years and quietly stay underdosed.

The High-Concentration Shortcut: Good Fats

This exact maths problem is why we created Good Fats.

Not to be clever. Not to reinvent Omega 3. Just to make the numbers work in real life.

Each Good Fats capsule contains 1000mg of fish oil in a 50/25 formulation.

That means roughly 500mg of EPA and 250mg of DHA in every capsule.

In plain English, one capsule delivers around 750mg of combined EPA and DHA.

That comfortably clears the NHS baseline in one go.

If your diet already includes some oily fish, one capsule a day does the job. If your intake is lower, taking two still feels simple and manageable.

No handfuls of capsules. No label gymnastics. No guessing how many you need.

Why High-Potency Oils Are Easier to Stick To

When the maths works, habits stick.

Fewer capsules mean better consistency. Better consistency means your omega 3 daily intake stays steady.

And that’s what matters most.

Not perfection. Just showing up every day.

Stop Guessing. Start Counting What Matters

Omega 3 isn’t magic.

But it is essential.

And the difference between “taking it” and “getting enough” comes down to simple numbers.

EPA. DHA. Concentration.

Once you understand those, the confusion disappears.

And so does the need to swallow half a bottle every day.
