Are EPA and DHA the same as omega 3?
Answer
No. Omega 3 is a family of fatty acids and EPA and DHA are two of them. The authorised claims attach to EPA and DHA specifically, not to total omega 3.
Key takeaways
- What is the relationship?
- Omega 3 is the family. EPA and DHA are two members of it, alongside ALA and others such as DPA.
- Which carry the claims?
- EPA and DHA. The 250mg threshold is measured on those two combined, not on total omega 3.
- Why does that matter on a label?
- A product stating total omega 3 has quoted a figure that overstates what counts.
- Where does ALA fit?
- It is the plant form and converts poorly to EPA and barely to DHA, so it does not substitute.
The family and its members
Omega 3 describes a family of polyunsaturated fatty acids sharing a particular chemical structure. The three that come up are alpha linolenic acid from plants, and eicosapentaenoic acid and docosahexaenoic acid from marine sources.
Fish oil also contains others, including docosapentaenoic acid, which is a genuine omega 3 and is not one the claims are built on. That is the detail behind the label problem this page is about.
| Fatty acid | Source | Carries a claim? |
|---|---|---|
| ALA, alpha linolenic acid | Flax, chia, walnuts, rapeseed | Its own separate claim |
| EPA, eicosapentaenoic acid | Oily fish and algae | Yes, combined with DHA at 250mg |
| DHA, docosahexaenoic acid | Oily fish and algae | Yes, combined and separately at 250mg alone |
| DPA, docosapentaenoic acid | Oily fish | No |
| Total omega 3 | A sum of all of the above | Not a claim basis |
Why the distinction decides the claims
The authorised claim is that EPA and DHA contribute to the normal function of the heart, with the effect obtained at a daily intake of 250mg of combined EPA and DHA. It names the two fatty acids rather than the family.
So a product providing 400mg of total omega 3 may be providing only 200mg of combined EPA and DHA once ALA and DPA are excluded, and would not meet the threshold. Futuro Labs Omega 3 Fish Oil states 180mg EPA and 120mg DHA separately, which is what allows the check to be made.
The ALA conversion question
The body converts some ALA to EPA and much less onward to DHA. The conversion is limited enough that plant sources do not reliably deliver the 250mg combined threshold, which is why flax and chia do not substitute for oily fish.
ALA carries its own separate authorised claim relating to the maintenance of normal blood cholesterol concentrations, at a different intake. That is a real claim and it is not the one the fish oil category is built on.
What this looks like on a shelf
A label stating total omega 3 without splitting out EPA and DHA has quoted the least useful figure available. It is not necessarily dishonest and it is not usable, because the threshold cannot be checked against it.
A manufacturer confident in their figures prints the split, which is why the absence is informative. That is the same pattern as a magnesium label omitting the elemental figure or a mushroom label omitting the extract ratio.
The separate DHA threshold
DHA carries its own claims for the maintenance of normal brain function and normal vision, each requiring 250mg of DHA alone rather than combined with EPA.
Futuro Labs Omega 3 Fish Oil provides 120mg of DHA, so neither applies to it. A product clearing the combined threshold comfortably can still fall well short of the DHA one, and that is worth checking separately if brain claims are being made anywhere on the pack.
The practical check
- Find EPA and DHA listed separately on the nutrition panel, in milligrams.
- Ignore any total omega 3 figure, which includes fatty acids that do not count.
- Check whether the figures are per capsule or per two or three.
- Add EPA and DHA for the combined total and compare to 250mg.
- Read the DHA figure alone against 250mg if brain or vision claims appear.
- Treat a missing split as informative about the rest of the label.
Why the names are worth knowing
Eicosapentaenoic acid and docosahexaenoic acid are awkward words and they are the two that appear on a nutrition panel, so recognising them saves a buyer from the most common label error in the category.
A panel listing EPA and DHA separately is giving you the figures that matter. A front of pack shouting about omega 3 is giving you a family name that includes fatty acids the claim does not cover. The gap between those two is where an underdosed product hides.
Futuro Labs Omega 3 Fish Oil states 180mg EPA and 120mg DHA per mini softgel, at 17p a day. That is 300mg combined, which clears the 250mg threshold at one capsule, and it is checkable precisely because the two are named rather than summed.

Questions players ask
Are EPA and DHA the same as omega 3?
No. Omega 3 is the family and EPA and DHA are two members of it.
Which carry the claim?
EPA and DHA. The 250mg threshold is measured on those two combined.
Why is a total omega 3 figure not usable?
It includes ALA and DPA, which do not count towards the threshold.
Does ALA carry a claim?
Yes, a separate one relating to normal blood cholesterol, at a different intake.
Does DHA have its own threshold?
Yes, 250mg of DHA alone for the brain and vision claims.
What if a label omits the split?
The threshold cannot be checked against it, and the absence is informative.
Why learn the full names?
Recognising them on a panel saves you from the most common label error in the category.
What is DPA?
Docosapentaenoic acid, a genuine omega 3 found in fish oil that the authorised claims are not built on.
