Omega-3

Also called omega 3, fish oil, cod liver oil and 5 more

krill oil, algae oil, algal oil, EPA, DHA.

Cheapest omega-3 fish oil today: 11p per 1 g EPA + DHA at Myprotein, of 140 products at 18 shops. Checked 29 October 2026.

The best price per 1 g EPA + DHA and per month, form by form, across 19 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.

Comparing omega-3

We count the EPA + DHA a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Omega-3 comes as fish oil, krill oil, algae oil (vegan) and cod liver oil, and each form has its own table, because someone buying one would not usually take another as a like-for-like substitute. A product with one other ingredient is ranked here with an “also contains” note; products that combine omega-3 with several others are listed separately, because their price buys more than EPA + DHA. 1 g is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

Omega-3 Fish oil

Most prices last checked: ; an older price shows its own date. Ranked purely by price per 1 g EPA + DHA — a comparison unit, not a recommendation. We earn commission when you buy through these links; it never affects the order.

7 of the 10 cheapest links on this page earn us nothing; the order is price alone. Shop by shop

By shop

Each shop's Omega-3 products, with where its cheapest sits in the market.

How we work out these prices

We count EPA + DHA — the components stated on the label — not the weight of the oil. A 1,000 mg capsule of oil can contain very different amounts of EPA + DHA. Products that state only the oil weight are left out until the content is confirmed.

Questions

Where can I buy omega-3 cheapest in the UK?

On 29 October 2026, the cheapest omega-3 per dose from a UK seller was High Strength Omega 3 | 2340mg at Myprotein (11p per 1 g EPA + DHA, £3.36 a month). Then Super Strength Omega 3 Fish Oil 2000mg at ZipVit (14p per 1 g EPA + DHA, £4.09 a month) and High Strength Omega 3 | 2340mg at Myprotein (14p per 1 g EPA + DHA, £4.22 a month). That is by price per 1 g EPA + DHA, across 18 UK retailers and 145 products, with every price checked daily; the table above shows the working for each.

What is the best price per 1 g EPA + DHA of omega-3 today?

11p per 1 g EPA + DHA, for High Strength Omega 3 | 2340mg at Myprotein (11p per 1 g EPA + DHA, £3.36 a month), on 29 October 2026. The dearest of the 145 products we price is £34.09 per 1 g EPA + DHA, and the middle one is 51p.

How much does omega-3 cost per month?

At one 1 g dose a day, the cheapest works out at £3.36 a month, for High Strength Omega 3 | 2340mg at Myprotein, on 29 October 2026. Across the 145 products we price it runs from £3.36 to £1022.69 a month. A month is 30 days, and the figure follows the dose you enter in the table.

Which omega-3 form is cheapest per dose?

On 29 October 2026: cod liver oil from 11p per 1 g EPA + DHA (Simply Supplements), fish oil from 11p per 1 g EPA + DHA (Myprotein), algae oil (vegan) from 49p per 1 g EPA + DHA (WeightWorld) and krill oil from £1.25 per 1 g EPA + DHA (WeightWorld). The forms differ in what they contain, so this is a fact about price and not a recommendation of one over another.

Do bigger omega-3 packs cost less per dose?

Mostly, yes: on 29 October 2026, the 5 packs that last more than six months average 17p per 1 g EPA + DHA, against 89p for the 140 that last six months or less. The table marks the cheapest pack that lasts six months or less as the best value for anyone who would rather not buy a year at once.

How long does a pack of omega-3 last?

At one 1 g dose a day, the packs we price last from under a day to 1.8 years; the middle one lasts 50 days. Each row says how long its pack lasts at the dose you enter.

What does “per 1 g EPA + DHA” mean?

It is the unit we use to put every product on the same scale: the price of 1 g of EPA + DHA, whatever the pack size or serving size. It is a comparison unit, not a recommendation of how much to take. Use the “Your daily dose” box to see costs at the amount you actually take.

Why are the omega-3 forms in separate tables?

We only rank products against others of the same form, because someone buying one form would not usually see another as a like-for-like substitute on price. Forms we compare separately: Fish oil; Krill oil; Algae oil (vegan); Cod liver oil.

Why is a product I have seen in the shops missing?

If a retailer’s listing does not let us confirm the amount per serving, the pack size or the form, we do not guess and we do not show the product. It appears once its label has been read and confirmed.

How up to date are the prices?

Prices on this page were last checked on 29 October 2026. Every table shows the date its prices were checked. Always confirm the price on the retailer’s site before buying.

Do retailers pay to appear higher?

No. We earn a commission when you buy through our links, but the order is set only by price per dose. No retailer or brand can pay for position.
