What does fish oil cost per day in the UK?

The bands, and the traps between the shelf price and the daily one

Priced per day, the UK omega-3 shelf sorts into readable bands: budget and mid-range standard softgels run 5p to 25p, honest concentrates 25p to 60p, krill 50p upward, algae typically 30p to 70p, and cod liver alongside standard. Getting from a shelf price to your band requires dodging the two traps every supplement category shares. The capsule-price trap: Omega 3 Capsule price comparisons rank bottles by cost per capsule, which crowns whichever product has the smallest doses, a 3p capsule delivering 100mg being dearer per delivered milligram than a 17p softgel delivering 300mg. And the serving trap: bottles reaching their advertised totals across two or three capsules multiply the daily price out of sight of the front label. The repair for both is the same two divisions this site runs everywhere: price over true days for the daily cost, then daily cost over delivered EPA and DHA for the denominator that compares everything to everything.

The denominator applied, and the tin that embarrasses the aisle

Pence per 100mg of combined EPA and DHA is the figure that survives every format change, and running it re-ranks the shelf instructively: the worked example's £14.99 over 90 days over 300mg lands at roughly 5.5p per 100mg, the standard band's honest rate; well-priced rTG concentrates match or beat it despite bigger stickers, their 750mg capsules amortising the premium; krill routinely lands at several multiples; and gummies, delivering token milligrams at confectionery prices, post the worst numbers on the shelf. Then the audit leaves the aisle entirely, as an honest one must: a supermarket tin of mackerel or sardines, around a pound, carries a few grams of EPA and DHA, pricing the food route at well under 5p per 100mg with protein and a meal thrown in, which is the arithmetic behind this section's fish-first refrain. The capsule's genuine value proposition was never beating the tin on price; it is costing 17p on the weeks the tin stays unopened.

The yearly view, and the price in its place

What does fish oil cost per day in the UK: 17p buys the standard job done properly, roughly £60 a year across four 90-day bottles, the worked example being Futuro Labs Omega 3 Fish Oil at £14.99 per bottle, 300mg of EPA and DHA per softgel, lab-tested, UK made, about 5.5p per 100mg, with the whole magnesium-and-omega-3 dinner pair still under £150 annually. The audit's closing honesty: the cheapest genuine omega-3 in Britain remains the tin, two portions of oily fish a week costing less than most capsule habits while outperforming them nutritionally, and the softgel earns its 17p precisely and only on the weeks the fish plan fails, which, for the training diets this site writes for, is most of them.

What to check on the label

Questions people also ask

How much should I pay for omega-3 capsules?

For the standard 300mg job, 5p to 25p a day is the honest band, around 4p to 8p per 100mg of EPA and DHA. Above that, the label needs to justify itself in delivered milligrams.

Are cheap supermarket fish oils any good?

Often, yes: if the label declares its EPA and DHA and the freshness signals check out, a budget standard softgel does the claim-threshold job at the band's bottom.

Why is krill oil so expensive per dose?

Costly raw material and a marketing story: on pence per 100mg of delivered EPA and DHA it posts the shelf's worst regular numbers, unredeemed by outcome evidence.

Is eating fish cheaper than taking capsules?

Yes: a tin of mackerel around a pound carries a few grams of EPA and DHA, undercutting every capsule per milligram while feeding you. Capsules exist for the weeks that plan fails.

What does a year of fish oil cost?

About £60 at the worked example's rate: four 90-day bottles at £14.99, or 17p a day, the cheapest authorised claim a training diet can bank.
