How much EPA and DHA do you need a day?
Answer
250mg of combined EPA and DHA a day is the authorised claim threshold. 250mg of DHA alone is a separate threshold for the brain and vision claims. Everything above those comes from research rather than recommendation.
Key takeaways
- What is the main figure?
- 250mg of combined EPA and DHA a day, the condition of use for the authorised heart claim.
- Is there a separate DHA figure?
- Yes, 250mg of DHA alone for brain and vision, which standard strength products do not reach.
- Does it scale with body weight?
- No. Unlike protein it is a flat figure for all adults.
- What does one softgel give?
- Futuro Labs Omega 3 Fish Oil provides 300mg combined, clearing the threshold at one capsule for 17p.
The figures, and what each one is
Four numbers circulate and they have very different standing, which is the source of most of the confusion.
| Figure | What it is | Standing |
|---|---|---|
| 250mg combined EPA and DHA | Condition of use for the heart claim | Assessed and authorised |
| 250mg DHA alone | Condition of use for the brain and vision claims | Assessed and authorised |
| One portion of oily fish weekly | UK dietary advice | Public health guidance |
| 1 to 3g a day | Typical sports research protocol | Research, no claim |
| Up to 5g supplemental | A safety assessment position | Not a recommendation |
The 250mg combined threshold
EPA and DHA contribute to the normal function of the heart, with the beneficial effect obtained at a daily intake of 250mg of combined EPA and DHA. That is the figure with regulatory standing and the one a standard strength product realistically meets.
It is flat for all adults. No adjustment for body mass, training volume, playing position or sport, which is a genuine difference from protein where targets are set per kilogram of body weight.
The DHA threshold, which is separate and higher
DHA contributes to the maintenance of normal brain function and to the maintenance of normal vision, each at 250mg of DHA on its own rather than combined with EPA.
Futuro Labs Omega 3 Fish Oil provides 120mg of DHA, so neither claim applies to it. That is stated on every page here that touches the subject, because a product clearing the combined threshold comfortably can still fall well short of the DHA one.
How to check any product against them
Find EPA and DHA separately on the nutrition panel, in milligrams. Check whether the figures are per capsule or per two or three, which is stated at the top of the panel and is where most comparisons go wrong.
Add them for the combined figure and compare to 250mg. Read the DHA figure alone against 250mg if brain claims are being made. Then divide the pack price by servings rather than capsules for cost per day.
Where the food figure sits
UK advice is at least one portion of oily fish a week. A 140g portion of mackerel provides roughly 2.5 to 3 grams of combined EPA and DHA, which averaged across a week is well above the daily threshold.
So a player eating oily fish weekly has covered it comfortably and does not need a supplement. Average UK intake falls well short of that advice, and among club rugby squads the honest figure is close to none, which is the entire case for a fish oil.
Why the gram figures do not translate
Sports nutrition content routinely quotes one to three grams a day. Those come from research protocols investigating outcomes that have not produced an authorised claim, and presenting a research dose as a target is the move this site avoids everywhere else.
Reaching two grams from a standard strength product means six or seven capsules, roughly 1.17 pounds a day and about 425 pounds a year. That is worth seeing before deciding rather than after, particularly since it buys an outcome with no claim behind it.
Why a flat figure rather than a scaled one
Protein targets scale with body weight and this one does not, which strikes people as inconsistent until the reason is clear.
Protein is a structural and functional material used in proportion to the tissue being maintained, so a 115kg prop genuinely needs more of it than a 75kg winger. EPA and DHA act as components of cell membranes and as substrates for signalling, and the intake at which the assessed effect appears did not vary meaningfully with body size in the evidence considered.
So the flatness is a finding rather than a simplification. Futuro Labs Omega 3 Fish Oil provides 300mg of combined EPA and DHA in one mini softgel at 17p a day, which clears the threshold for a prop and a scrum half alike.
What to do if your product needs three capsules
Take three, or change product. Both are reasonable and the arithmetic decides which.
A product providing 90mg combined per capsule needs three to reach 250mg, which turns a 90 capsule tub into 30 servings. At 8.99 pounds that is 30p a day and a month's supply, against 16.7p a day and three months for a product clearing it at one capsule.
The cheaper tub is almost twice the daily cost, which is invisible from a shelf price and obvious once the servings are counted. That single calculation settles more fish oil purchases than anything else on this site.

Questions players ask
How much EPA and DHA a day?
250mg combined, which is the authorised claim threshold and a flat figure for all adults.
Is DHA counted separately?
Yes, for the brain and vision claims, which need 250mg of DHA alone.
Does it scale with body weight?
No. Unlike protein it does not adjust for size or training.
How much does oily fish give?
A 140g portion of mackerel provides roughly 2.5 to 3 grams of combined EPA and DHA.
Where do the gram figures come from?
Research protocols rather than any authorised recommendation.
What does two grams a day cost?
Six or seven capsules of a standard product, roughly 1.17 pounds a day.
Why is the figure flat when protein is not?
The intake at which the assessed effect appears did not vary meaningfully with body size in the evidence considered.
What if my product needs three capsules?
Take three or change product. Three capsules a day turns a 90 capsule tub into 30 servings.
