Say no to artificial additives! This supplement has no filler oils or artificial ingredients. It costs more, but you’ll benefit from the healthier premium formula.

Frequently Asked Questions about Omega 3 Fish Oil

Yes, this omega-3 fish oil supplement undergoes rigorous third-party testing to ensure it is free from heavy metals, PCBs, and other contaminants. It is made using molecular distillation, which removes impurities and guarantees a high level of purity and safety for daily consumption.

Vegan omega 3 made from algae is a great alternative for people with fish allergies or who stick to strict vegan diets. However, it contains a lot less EPA and DHA than fish oil, and the ratio between these two oils is inverted, with a lot less EPA than DHA. It’s the EPA that does most of the heavy lifting when it comes to reducing inflammation and helping to protect the heart. For this reason, traditional oil from fish is still the better choice for most people. 

EPA has powerful anti-inflammatory properties that help reduce inflammation throughout the body, which is particularly beneficial for heart health, joint comfort, and immune function. You need a high EPA content, like the 660 mg in this supplement, to help relieve arthritis pains, improve cardiovascular markers and help reduce inflammation.

Our omega-3 fish softgels give you a high dose of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which are essential for maintaining heart health, supporting brain function, reducing inflammation, and promoting joint mobility. The high concentration of 660 mg EPA and 440 mg DHA specifically helps lower triglycerides, improve cognitive function, and support overall cardiovascular wellness. Scroll down to our Scientific References section for more information. 

DHA forms 12% of the human brain as a major structural component. It’s vital for cognitive function, memory, and overall mental health. The 440 mg of DHA in this supplement helps protect brain cells, improve communication between neurons, and may reduce the risk of cognitive decline and memory loss associated with ageing.

This supplement's combination of 660 mg EPA and 440 mg DHA helps lower triglyceride levels, reduce blood pressure, and improve overall cholesterol balance. Regular intake can reduce the risk of heart disease by preventing plaque buildup in the arteries, promoting better circulation, and decreasing the risk of arrhythmias.

Yes, omega-3 fatty acids, particularly DHA, are known to help maintain skin hydration, elasticity, and a healthy barrier function. The anti-inflammatory properties of both EPA and DHA can also help reduce skin conditions like acne, psoriasis, and eczema, leading to healthier, more radiant skin.

Good quality omega 3s

Easy to swallow; high quality packaging; great quality soft gels. Easy to swallow with no flavour and good quality for the money.

Luisa Hoggard, Sunderland

Really happy to find these

These are stronger than my previous brand and also cheaper, so it's a win-win for me. Me and my husband both take them, I think they help with brain fog that I started getting in menopause and he takes them to try and keep his heart and arteries healthy because he doesn't like fish. Good job he can't taste these.

More About Pro Omega 3

If you've ever picked up a supermarket fish oil and wondered why your body doesn't seem to notice it, you're probably looking at a low-strength product with poor EPA and DHA content. Some generic fish oils contain just 180mg of EPA and 120mg of DHA per capsule. Pro Omega 3 was built differently. Each serving provides 2,000mg of fish oil delivering 1,100mg of omega 3 fatty acids, including 660mg EPA and 440mg DHA. It's the high strength omega 3 most adults over 40 actually need.

What Is Omega 3 and Why the Strength Matters

Omega 3 fatty acids are essential fats your body can't produce on its own. You have to get them from food or supplements. The two most important forms are EPA (eicosapentaenoic acid), which sits in your blood vessels, cell membranes, and immune cells and plays a central role in reducing inflammation, and DHA (docosahexaenoic acid), which forms around 12% of the structural fat in your brain and is concentrated in the retina of your eyes.

The UK diet doesn't deliver much of either. The NHS recommends two portions of oily fish per week, including one of salmon, mackerel, sardines, or herring. According to the National Diet and Nutrition Survey, the average UK adult eats less than half that amount. The result is that millions of people are running on lower-than-ideal levels of EPA and DHA without realising it.

Why Choose Pro Omega 3 from Swallow?

2,000mg of Fish Oil, 1,100mg of Omega 3 Per Serving

Each two-softgel serving provides 2,000mg of pure fish oil, delivering 1,100mg of omega 3 fatty acids in total. That breaks down to 660mg of EPA and 440mg of DHA, the active forms your body actually uses. This is a genuinely omega 3 high strength formula, not a label-dressed version of a low-concentration oil.

The higher EPA content matters in particular. EPA is the form most associated with anti-inflammatory effects, cardiovascular support, and joint comfort.

Molecular Distillation and Third-Party Testing

Fish accumulate environmental contaminants over their lifetime, which is why the source and purification of fish oil supplements matter more than people often realise. Pro Omega 3 is purified using molecular distillation, a process that removes mercury, PCBs, dioxins, and other contaminants while preserving the fragile omega 3 fatty acids. Every batch is independently lab-tested for purity, oxidation, and contaminants. The oil is also stabilised with mixed tocopherols (natural vitamin E) to protect it from going rancid before you take it.

Sustainably Sourced, Friend of the Sea Certified

The fish oil in Pro Omega 3 is certified by Friend of the Sea, an independent organisation that audits fishing practices for sustainability. That means the oil comes from fisheries that manage their stocks responsibly, use selective fishing methods to reduce bycatch, and meet strict environmental standards. Fish oil should not come at the cost of the ocean it comes from.

Clean Formula, No Filler Oils

A surprising number of fish oil supplements bulk up their softgels with cheaper filler oils like soybean or sunflower oil, so what looks like a 1,000mg fish oil capsule actually contains far less. Pro Omega 3 contains no filler oils, no artificial additives, and no flavourings beyond natural mixed tocopherols. The only ingredient in the softgel beyond fish oil is the gelatine and glycerine that make up the capsule shell itself.

Note: the softgel shell uses bovine gelatine, so Pro Omega 3 is not suitable for vegetarians or vegans. It contains fish, so it's not suitable for anyone with a fish allergy.

Key Benefits of High Strength Omega 3

The following health claims about EPA and DHA have been approved by the European Food Safety Authority (EFSA):

EPA and DHA contribute to the normal function of the heart (at a daily intake of 250mg).

DHA contributes to the maintenance of normal brain function (at a daily intake of 250mg).

DHA contributes to the maintenance of normal vision (at a daily intake of 250mg).

EPA and DHA contribute to the maintenance of normal blood pressure (at a daily intake of 3g).

EPA and DHA contribute to the maintenance of normal blood triglyceride levels (at a daily intake of 2g).

Omega 3 for Heart Health

The American Heart Association recommends EPA and DHA specifically for reducing triglycerides.

EPA also supports normal blood pressure, healthy cholesterol balance, and the rhythm of the heart. It's one of the reasons cardiologists routinely recommend oily fish to patients with cardiovascular risk factors.

Omega 3 for Brain Function and Cognitive Support

DHA forms around 12% of the structural fat in the human brain. It's a major component of nerve cell membranes and the membranes that surround the synapses, where brain cells communicate with each other.

Many customers in their 50s and 60s notice an improvement in mental clarity and a reduction in brain fog after a few months of consistent use, particularly women going through perimenopause and menopause when oestrogen-related cognitive changes are at their most noticeable.

Omega 3 for Joints and Inflammation

EPA in particular has anti-inflammatory effects. It works by influencing the production of eicosanoids, the signalling molecules that drive much of the body's inflammatory response.

For everyday joint comfort, particularly in adults over 50 dealing with osteoarthritis-related stiffness, an omega 3 high strength supplement can be a useful daily addition to a joint support routine.

Omega 3 for Mood and Mental Resilience

The relationship between inflammation, omega 3 status, and mood is one of the more interesting areas of recent nutrition research, with growing evidence that low EPA levels are linked to a higher risk of depressive symptoms.

Omega 3 for Skin Hydration and Barrier Function

EPA and DHA are incorporated into the lipid layer of the skin, where they help maintain hydration, elasticity, and a healthy barrier against environmental stressors. The anti-inflammatory effects of omega 3 can also help with skin conditions that have an inflammatory component, including acne, eczema, and psoriasis.

Who Should Consider Pro Omega 3?

Pro Omega 3 is suitable for most adults and is particularly worth considering if you:

Don't eat oily fish at least twice a week, which describes the majority of UK adults.

Are over 40 and want to support heart, brain, and joint health together with a single daily supplement.

Have raised triglycerides, borderline blood pressure, or cardiovascular risk factors and want a nutritional approach alongside lifestyle changes.

Are dealing with joint stiffness or inflammatory aches and want a high strength omega 3 to support an anti-inflammatory routine.

Are going through perimenopause or menopause and noticing brain fog, mood dips, or skin changes.

Have tried lower-strength fish oils without much effect, possibly because the EPA and DHA doses were too low.

Want a clean, sustainably sourced, lab-tested, UK-formulated omega 3 high strength supplement without filler oils or artificial additives.

How to Take Pro Omega 3

Take two softgels daily with food. Omega 3 is a fat-soluble nutrient, so taking it with a meal that contains some dietary fat (like avocado, eggs, or a piece of cheese) meaningfully improves absorption. Many customers take their two softgels with breakfast or lunch.

Pro Omega 3 has no fishy aftertaste when stored properly. Keep the bottle in a cool, dry place out of direct sunlight, which preserves the oil and the natural vitamin E that protects it.

Most omega 3 benefits build over 60 to 90 days of consistent daily use. Changes in joint comfort and inflammation markers often appear first, followed by cognitive and mood benefits over the following weeks.

Caution: speak to your GP before use if you are taking blood-thinning medication such as warfarin, since omega 3 can have a mild blood-thinning effect at high doses. Stop taking the supplement at least two weeks before any planned surgery. Not suitable for anyone with a fish allergy. Pregnant or breastfeeding women should consult a healthcare professional before starting any new supplement.

Clean, Ethical, and Made in Britain

Swallow supplements are made in the UK in GMP-certified facilities to pharmaceutical-grade standards. Every batch of Pro Omega 3 is independently tested for purity, potency, oxidation, and heavy metal content. The fish oil is sustainably sourced and Friend of the Sea certified. The bottle is recyclable, with compostable inner packaging. Like every Swallow product, Pro Omega 3 is backed by a six-month money-back guarantee.

The Best High Strength Omega 3, Delivered to Your Door

Whether you're looking to support your heart, your brain, your joints, your mood, or your skin, the evidence behind EPA and DHA at the right doses is among the strongest in the supplement world. The catch is that you have to take a high strength omega 3, not a low-dose generic fish oil.

Pro Omega 3 gives you 1,100mg of omega 3 fatty acids, including 660mg of EPA and 440mg of DHA, in two daily softgels. Sustainably sourced, molecularly distilled, third-party tested, and made in the UK. Free UK delivery on every order, fast dispatch from our UK warehouse, and a six-month money-back guarantee on every product.

    Jury's Still Out

    Product as described.

    No nasty aftertaste.

    Still waiting to notice any benefits but will give it another month.

    If no noticeable benefits in that period will stop on grounds of cost.
