Top 7 Cod Liver Oil Supplements in the UK for 2026
Published on Wednesday, 25 February 2026
Cod liver oil supplies vitamins A and D alongside EPA and DHA, and the vitamin A is the part that decides whether it suits you. NHS advice is not to take cod liver oil, or any supplement containing vitamin A (retinol), during pregnancy, because too much can harm the baby's development. For everyone else, total vitamin A from food and supplements should stay under 1.5 mg (1,500 µg) a day; averaging more than that over years may weaken bones. If liver or pâté is already in your weekly diet, a fish liver oil on top is not advised. On omega-3, cod liver oil is a dilute source: a 1,000 mg capsule typically gives only around 100-200 mg of EPA plus DHA combined, below the 250 mg a day linked to normal heart function under GB/EU authorised claims, so most people need two capsules or a liquid dose - which doubles the vitamin A too. UK vitamin D advice is separate and simple: 10 µg (400 IU) daily through autumn and winter, which most cod liver oils cover. The only claims permitted on these products concern EPA and DHA for normal heart function at 250 mg a day and vitamin D for normal bones, muscle and immune function; anything about joints, arthritis or immune boosting is marketing, not an authorised claim. Buy on three things: EPA, DHA and vitamin A stated per serving on the label, independent contaminant testing, and a format you will actually take daily.

Bare Biology Lion Heart Liquid Cod Liver Oil
Lion Heart is Bare Biology's concentrated omega-3 fish oil, not a cod liver oil. It is pressed from wild-caught anchovy, sardine and mackerel rather than cod livers, so it carries no naturally occurring vitamin A or vitamin D. Bare Biology has since renamed the range Life & Soul; remaining Lion Heart stock is the same oil under the former name. It appears here as the honest dose comparison: the daily capsules supply roughly 1,700 mg of omega-3 per two-capsule serving, of which about 1,100 mg EPA and 500 mg DHA, several times what any cod liver oil on this page reaches - and it does so without adding to your vitamin A intake. Fish is sourced from Norwegian suppliers certified by Friends of the Sea and Marin Trust, with independent batch testing on top of the producer's own.

What UK guidance and the evidence actually support for cod liver oil
Cod liver oil is judged on two separate things that pull against each other: its omega-3 (EPA and DHA) dose, and its fat-soluble vitamin A and D content. Raising one raises the other. UK guidance on vitamin A is stricter than most product pages admit, and the authorised GB/EU health claims are narrower than the marketing around this category. The points below separate what may lawfully be claimed from what remains unsettled.
Vitamin A is the limiting factor: NHS advice is to keep total vitamin A from food and supplements below 1.5 mg (1,500 µg) a day, because averaging more than that over many years may affect your bones. Fish liver oils are a high-vitamin-A source, so check the labelled µg figure before adding one to a diet that already includes liver.
Pregnancy: NHS advice is explicit - do not take cod liver oil or any supplement containing vitamin A (retinol) while pregnant, as too much can harm the baby's development. That rules the whole category out in pregnancy, regardless of brand, format or price.
Authorised claims only: under retained Regulation 1924/2006, EPA and DHA may be linked to normal heart function at an intake of 250 mg a day, and vitamin D to normal bones, muscle function and immune system function. Claims that omega-3 treats joint pain or arthritis, or that cod liver oil boosts immunity, are not authorised and should be read as marketing rather than evidence.
Omega-3 dose per serving: cod liver oil is dilute compared with concentrated fish oil. A 1,000 mg cod liver oil capsule usually delivers around 100-200 mg of EPA plus DHA combined, so reaching 250 mg a day often takes two capsules or a measured liquid dose - and that doubles the vitamin A alongside it.
Vitamin D: UK advice is 10 µg (400 IU) a day for everyone during autumn and winter, and year-round for people with little sun exposure. Most cod liver oils cover this, but a plain vitamin D supplement does the same job with no vitamin A load at all.
Cardiovascular and cognitive evidence: randomised trials and meta-analyses consistently show omega-3s lower triglycerides, while effects on major events such as heart attack and stroke vary by dose and population. Cognitive findings are mixed and strongest where baseline omega-3 intake is low; none of it supports prevention of dementia.
Purity and label quality: look for an independent certificate covering heavy metals, dioxins and PCBs - IFOS or an equivalent third-party laboratory report - and a label that states EPA, DHA and vitamin A per serving rather than only the total oil weight in milligrams.
Frequently Asked Questions
Can you take cod liver oil when pregnant?
No. NHS advice is not to take cod liver oil, or any supplement containing vitamin A (retinol), during pregnancy, because too much vitamin A can harm your baby's development. That applies to every product on this page, including the premium liquids. Pregnant women who want omega-3 are usually directed to a plain fish oil or algae DHA that contains no vitamin A, plus 10 µg of vitamin D separately - check with a GP, midwife or pharmacist first.
How much cod liver oil is too much?
The binding number is vitamin A, not omega-3. NHS advice is to keep total vitamin A from food and supplements under 1.5 mg (1,500 µg) a day, because averaging more than that over many years may affect your bones. Read the µg figure on the label, add anything from liver or pâté in your diet, and avoid stacking a cod liver oil with a multivitamin that also contains retinol.
Is cod liver oil better than fish oil for omega-3?
No - it is weaker per gram. A 1,000 mg cod liver oil capsule typically supplies around 100-200 mg of EPA plus DHA, below the 250 mg a day linked to normal heart function under GB/EU authorised claims, whereas a concentrated fish oil reaches that in a single capsule. Cod liver oil's real advantage is its naturally occurring vitamins A and D, and that is also its ceiling: you cannot raise the omega-3 dose without raising the vitamin A with it.
Which cod liver oil is best for everyday capsules?
Seven Seas Simply Timeless Cod Liver Oil One-A-Day is the simplest everyday option here: one capsule daily, natural vitamins A and D from cod liver oil, and the widest high-street availability of the group, with a 4.6 average rating. As with any fish liver oil, check the vitamin A per capsule against the 1.5 mg daily ceiling before you add anything else containing retinol.
