What is the “inflammation ratio” and why does it matter?

The inflammation ratio refers to the balance between omega-6 and omega-3 fats in your diet. Ideally, this ratio is close to 1:1. In modern diets, it is often closer to 25:1 in favour of omega-6. That imbalance can contribute to low-grade, ongoing inflammation that affects how you feel day to day. Omega-3 helps restore balance, which is why it is linked to benefits across heart, brain, joint, and general health.

Why is omega-3 important for brain function and mental clarity?

A specific omega-3 fat called DHA makes up a large structural portion of the brain, including much of its gray matter. It is not just fuel for the brain, it is part of what the brain is built from. Research shows DHA supplementation can support memory, reaction time, and cognitive performance, particularly in people with low habitual omega-3 intake.

Can omega-3 support heart and cardiovascular health?

Yes. Clinical research shows omega-3 can help maintain healthy triglyceride levels already within the normal range and support overall heart health. Large trials have shown reductions in heart attack risk in certain populations, especially those with low fish intake. Omega-3 also supports healthy blood flow and vascular function.

How does omega-3 help with joint comfort and exercise recovery?

Omega-3 plays a role in regulating inflammatory messengers in the body. Studies in healthy athletes show that supplementation can reduce muscle soreness after intense exercise and help maintain performance during recovery. By supporting a healthy inflammatory response, omega-3 may also support joint comfort and flexibility.

Why isn’t eating fish once a week enough?

To meaningfully shift the omega-6 to omega-3 ratio, you need a consistent and sufficient intake of EPA and DHA. A single weekly serving of oily fish is unlikely to provide enough to rebalance a 25:1 dietary ratio. Achieving therapeutic levels through food alone would typically require frequent, near-daily consumption of oily fish, which many people find impractical.

What makes a high-quality omega-3 supplement different?

The key difference is concentration. Many standard supplements contain relatively low amounts of EPA and DHA per capsule, meaning you may need several capsules to reach an effective intake. A high-potency supplement delivers a meaningful amount of EPA and DHA per serving, focuses on clean, high-grade oil to avoid oxidation, and provides a balanced combination of both EPA and DHA to support brain, eye, heart, and general health.

We’ve all heard it. “Eat more oily fish.”

It’s the sort of advice that gets nodded at, agreed with, and then quietly ignored while you crack on with life. School runs. Deadlines. Dinner that needs to be on the table in 20 minutes.

Most people know omega-3 is “good for the heart”. That’s about where the knowledge ends.

So when you Google benefits of omega-3 and get hit with claims about eyesight, mood, skin, joints, metabolism, and even weight management, it feels… suspicious. One nutrient doing all that? Sounds like wellness bingo.

Here’s the truth, stripped of hype.

Omega-3 isn’t magic. It doesn’t “fix” you. What it does is far more boring, and far more useful.

It helps restore balance in a system that’s quietly been pushed way out of line.

That system is something most people have never heard of, but it connects every benefit you’ve ever read about omega-3.

We call it the inflammation ratio.

The One Big Thing Most People Miss: The Inflammation Ratio

If there’s one concept worth understanding, this is it.

Your body uses different fats for different jobs. Two of the big ones are:

Omega-6 fats – common in processed foods, vegetable oils, and modern convenience diets
Omega-3 fats – found in oily fish and a few other sources

Omega-6 isn’t “bad”. You need it. Omega-3 isn’t “good”. You need it too.

The issue is balance.

Health researchers often suggest the ideal ratio of omega-6 to omega-3 is close to 1:1.

The modern diet? Closer to 25:1.

That’s not a typo.

It means most people are swimming in omega-6 and scraping by on omega-3. The result isn’t dramatic overnight illness. It’s low-grade, background inflammation that never really switches off.

Not “I need a doctor” inflammation. More like “why do I always feel a bit creaky, foggy, or flat?” inflammation.

Omega-3 doesn’t put out fires because it’s special. It puts them out because it restores balance.

Once you understand that, all the “unexpected” benefits start to make sense.

Let’s break them down.

1. The Brain Structure Benefit (Focus, Clarity, Mood)

A lot of people treat poor focus or low mood like a personality flaw.

“I’m just not a morning person.” “My brain feels like treacle.” “That’s just stress.”

Sometimes it is. Sometimes it isn’t.

Here’s the bit most people never hear.

A specific omega-3 fat called DHA makes up a huge chunk of your brain’s structure. Roughly 40% of the polyunsaturated fats in the brain are DHA.

That means omega-3 isn’t just something your brain uses. It’s something your brain is literally built from.

If your intake is low, you’re not topping up a battery. You’re short on building materials.

Research has linked low DHA levels with poorer concentration, memory issues, and lower mood. Not because omega-3 is a happy pill, but because a brain built on poor-quality fats simply doesn’t run smoothly.

Think of it like this.

You wouldn’t expect a high-performance engine to run well on contaminated fuel. Yet we expect sharp thinking from brains built on whatever fats happen to show up in our diet.

When people increase omega-3 intake, many report feeling clearer, more even, and less “jangly”. Not wired. Not stimulated. Just… smoother.

The takeaway: Feed your brain properly. You can’t expect mental sharpness from low-quality building blocks.

2. The Metabolic Switch (Why Fat Can Help With Weight Management)

This is the one that makes people squint.

“How can eating fat help me manage body fat?”

Fair question.

The answer isn’t calories. It’s signals.

Chronic low-grade inflammation, remember that 25:1 ratio, is closely linked to poor insulin sensitivity. When insulin doesn’t work well, your body gets very good at storing energy and very bad at using it.

That’s not a willpower problem. It’s a signalling problem.

Omega-3s help calm the inflammatory noise that interferes with those signals. When that background stress eases, your metabolism can behave more normally.

Some studies suggest that, alongside a sensible diet, omega-3 intake may encourage the body to use fat for energy rather than clinging to it for dear life.

No promises. No miracles. Just better conditions for normal metabolic function.

This is why obsessing over the calories in fish oil misses the point. The message omega-3 sends is far more important than the small energy cost.

The takeaway: Stop fearing fat that supports balance. The signal matters more than the number.

3. The Fire-Extinguisher Effect for Everyday Joint Comfort

If you wake up feeling stiff, you’re not broken.

Modern life is hard on joints. Sitting too much. Moving too little. Then suddenly moving a lot at the weekend.

Joint discomfort is often linked to the body producing inflammatory messengers called eicosanoids and cytokines. When omega-6 dominates, these messengers get a bit shouty.

Omega-3s help tilt that conversation back toward calm.

In research settings, omega-3 intake has been shown to reduce the production of certain inflammatory compounds. That’s why people using omega-3 often describe feeling less creaky over time.

Not numbed. Not masked. Just less inflamed in the background.

This is also why omega-3 is so often compared to anti-inflammatory approaches, but without the downside of hammering one pathway while ignoring everything else.

The takeaway: Don’t just mute discomfort. Support the system that created it.

4. The “Internal Skincare” Benefit

We’re very good at putting things on our skin.

Creams. Serums. Oils. Half the bathroom shelf.

What we’re less good at is feeding the skin from the inside.

DHA is a structural component of skin cell membranes. It helps determine how flexible, hydrated, and resilient your skin looks.

EPA, another omega-3 fat, plays a role in regulating oil balance and hydration.

When people are low in omega-3, they often notice dry skin, dullness, or irritation that no cream quite fixes.

That’s because you can’t moisturise a cell that wasn’t built properly in the first place.

Omega-3 acts more like internal scaffolding than a topical plaster.

The takeaway: Healthy skin isn’t just what you apply. It’s what you’re built from.

5. The Volume Trap (Why “Just Eat More Fish” Rarely Works)

Here’s the part nobody tells you.

To meaningfully shift that omega-6 to omega-3 ratio, you need a therapeutic amount of EPA and DHA.

That’s not a token salmon fillet once a week.

To get there from food alone, you’d need to eat a decent portion of oily fish, salmon, sardines, mackerel, almost every single day.

For most people, that’s:

Expensive
Impractical
Socially awkward
And not without concerns around contaminants

So people turn to supplements.

Which is sensible. But also where things go sideways.

Most supermarket omega-3 supplements are low-potency. They look impressive on the front, but when you check the actual EPA and DHA content, it’s often tiny.

That’s why people end up swallowing handfuls of capsules and still not feeling much difference.

It’s not because omega-3 “doesn’t work”. It’s because they’re not getting enough of the bit that matters.

The Supplement Problem (And How We Approached It Differently)

This is where we’ll be upfront.

If you want the benefits of omega-3 without living on grilled mackerel, a supplement makes sense.

But you don’t need more pills. You need better ones.

At Lean Greens, we applied our usual rule to omega-3.

Rule of one: concentration.

Instead of padding capsules with filler oil, we focused on delivering a meaningful amount of EPA and DHA in every serving.

That’s how Good Fats was born.

Not flashy. Not trendy. Just properly dosed omega-3 for real life.

Why Good Fats Is Different

High potency: Many standard brands offer around 300mg of combined EPA/DHA per capsule. Good Fats delivers 750mg per capsule, so you get what you need without swallowing a handful.
No fishy repeats: Those dreaded “fish burps” usually come from oxidised or low-quality oil. We use clean, high-grade oil, and customers consistently report zero after-effects.
Balanced EPA and DHA: EPA supports mood balance and everyday comfort. DHA supports brain and eye structure. You need both.
No calorie panic: A daily serving comes in at around 40 calories, with zero sugar. Enough to send the right signals without sabotaging anything.

Good Fats isn’t about optimisation. It’s about fixing a quiet imbalance most people didn’t know they had.

If you’ve ever felt like you’re “doing the right things” but not quite getting the payoff, this is one of those boring, unsexy pieces that often gets missed.

Don’t settle for filler. Get the Good Fats.

Final Thoughts (No Wellness Lectures, Promise)

You don’t need to overhaul your life. You don’t need a new identity.

Most people just need a few quiet gaps filled.

Omega-3 is one of those gaps.

Not because it’s trendy. Because modern life stripped it out, and your body still expects it to be there.

Concludes that 4g/day of Omega-3s is effective for reducing triglycerides. Supports claims regarding maintenance of healthy blood lipid levels.

3. Table 2: Mechanism of Action (Animal & In Vitro)

Mechanism	Study Citation	Key Findings
Inflammation Resolution (Resolvins)	Serhan CN. Nature. 2014	EPA and DHA are enzymatic precursors to Resolvins, Protectins, and Maresins. These "Specialized Pro-resolving Mediators" (SPMs) actively terminate inflammation, preventing it from becoming chronic without suppressing the immune system.
Cell Membrane Fluidity	Calder PC. Biochem Soc Trans. 2005	Incorporation of EPA/DHA into phospholipid bilayers increases membrane fluidity. This enhances the function of membrane-bound receptors (e.g., insulin, neurotransmitters) and improves signal transduction efficiency.
Hepatic VLDL Synthesis	Harris WS, et al. J Lipid Res. 2008	Omega-3s inhibit the enzyme diacylglycerol acyltransferase in the liver, reducing the synthesis and secretion of VLDL particles, which directly lowers circulating triglyceride levels.
