Comparison
Best omega-3 in the UK for women
The best omega-3 for you comes down to source (fish oil, or vegan algae oil), the EPA and DHA amounts per serving, freshness and your dietary needs. Below we compare named UK brands. EPA and DHA have EFSA-authorised roles in normal heart function and, for DHA, brain function and vision, at the intakes EFSA specifies. The NHS recommends two portions of fish a week, one of them oily, first.

How we compared
Our methodology is disclosed and consistent. We shortlist real UK omega-3 brands across fish oil and algae sources, then compare them on source, format, EPA and DHA content and who each suits. We do not rank by affiliate commission, and we do not accept payment for a favourable placing. Where a buying link is not yet live, the link is marked as pending rather than guessed.
Frequently asked questions
What is the best omega-3 in the UK?
There is no single best. The sensible choice comes down to source (fish oil or vegan algae), the EPA and DHA amounts per serving, freshness and your dietary needs. We compare named UK products below so you can match one to your situation.
How did you choose these?
We shortlisted real UK omega-3 brands across fish oil and algae sources, then compared them on source, format, EPA and DHA content and who each suits. We do not rank by commission, and we add a buying link only once it is live. See our methodology below.
Fish oil or algae omega-3, which is better?
Both can provide DHA, and many algae products provide EPA too. The difference is source: fish oil from oily fish, or algae oil for vegans and those avoiding fish. Compare the EPA and DHA per serving rather than the total oil weight.
Do I need an omega-3 supplement?
Not necessarily. The NHS recommends two portions of fish a week, one of them oily, which provides omega-3. A supplement helps those who eat little or no oily fish. See our omega-3 guide for the context before you buy.
