Omega-3 is one of the most evidence-backed nutritional supplements available — but the quality difference between a premium fish oil and a cheap generic is substantial. The active components — EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) — need to be present in meaningful doses in a bioavailable form. This guide ranks the best UK options.
What to look for in an omega-3 supplement
| Factor | What to look for | What to avoid |
|---|---|---|
| Combined EPA+DHA per serving | 1,000mg+ for therapeutic use | Under 300mg per serving |
| Form | Triglyceride (TG) form — higher absorption | Ethyl ester (EE) form — lower absorption without fat |
| Purity | IFOS-certified or equivalent third-party testing | No purity certification on high-dose products |
| Freshness | No fishy burps; within date | Strong fishy smell indicates oxidised oil |
| Additional nutrients | Vitamin E for antioxidant protection of oil | Unnecessary fillers and additives |

Frequently Asked Questions
What is the difference between fish oil and omega-3?
Fish oil is the product; omega-3 (EPA and DHA specifically) are the active components within it. A fish oil supplement may contain only 30% omega-3 by weight — check the specific EPA+DHA content rather than total fish oil weight.
Do I need omega-3 supplements if I eat oily fish?
If you regularly eat two portions of oily fish per week (salmon, mackerel, sardines, herring, trout), your omega-3 intake is likely adequate. Most UK adults do not reach this target, and people on GLP-1 medication with reduced appetite rarely do.
What is the difference between EPA and DHA?
EPA (eicosapentaenoic acid) is primarily anti-inflammatory and cardiovascular-protective. DHA (docosahexaenoic acid) is primarily structural — particularly important for brain, eye, and nervous system health. Both are important; most evidence suggests the combined total EPA+DHA is more relevant than the ratio between them.
