Life Extension Super Omega-3 EPA...
Pros
- ✓IFOS 5-star certified and molecularly distilled — among the highest purity standards available for fish oil

- ✓Widely reported tangible benefits: improved cholesterol, reduced joint and systemic inflammation, better skin, hair, and nails
- ✓Minimal fishy aftertaste and good tolerability reported by the majority of reviewers
Cons
- ✗Softgels are noted as larger than average by multiple reviewers — may be difficult for those with swallowing issues
- ✗Omega form is not specified on labelling and is likely ethyl ester rather than triglyceride form, which has lower bioavailability
- ✗Contains sesame — a declared allergen increasingly relevant for sensitive individuals
- ✗Mild fish odour noted by a minority of reviewers, particularly after opening the capsule

What does the data say about Life Extension Super O... vs Omega-3 Fish Oil 1000mg?
Life Extension's Super Omega-3 (£24.99, 86/100) adds sesame lignans and olive polyphenols to its 700mg EPA+DHA—compounds that amplify anti-inflammatory activity beyond standard fish oil. IFOS 5-star certified and molecularly distilled. Nordic Naturals' Omega-3 (£70.20, 80/100) takes a different route: lemon flavouring eliminates fish taste, and vitamin D3 is included. You pay nearly three times more for taste and a second supplement.
Life Extension suits anyone serious about inflammation, cholesterol support, or DHA during pregnancy. Nordic Naturals works if fish oil's taste is genuinely unbearable, or you want omega-3 and vitamin D3 combined. The price gap is substantial enough that Life Extension wins for most people.
Both have large capsules. Life Extension uses ethyl ester form (lower bioavailability than triglyceride), whilst Nordic's form isn't specified. Life Extension's IFOS 5-star certification outweighs Nordic's complete lack of third-party testing.
Life Extension Super Omega-3 is a well-regarded fish oil supplement distinguished from standard options by the addition of sesame lignans and olive fruit extract (hydroxytyrosol), compounds with research-backed synergy with EPA and DHA for extended anti-inflammatory effect.

What the Data Says
What is the real cost per dose of omega-3 in the UK?
NOW Foods Ultra Omega-3 costs £0.22/serving — the cheapest effective dose we found across 21 products. That's 750mg EPA+DHA per serving, 90 servings per bottle at £19.99 (value-for-money score: 85/100).
Here's the full price-per-serving breakdown for our top-scoring products:
- NOW Foods Ultra Omega-3: £0.22/serving
- Moller's Omega-3 Liquid Lemon: £0.40/serving
- Life Extension Super Omega-3: £0.42/serving
- WHC UnoCardio 1000: £0.45/serving
- Carlson Elite Omega-3 Gems: £0.67/serving
- Solgar Triple Strength: £0.70/serving
The gap between cheapest and priciest is over 3x per dose. And expensive doesn't mean better — WHC UnoCardio scores highest overall (90/100) at just £0.45/serving, while Solgar scores 79/100 at £0.70. Always divide bottle price by serving count before you compare products.
How much EPA and DHA do you actually need?
250-500mg combined EPA+DHA daily for general health. 1000-2000mg for heart health support. Most health authorities land in that range, and clinical studies typically use 1000mg+.
Our top-scoring omega-3 products hit these targets well:
- WHC UnoCardio 1000 (90/100): 1000mg EPA+DHA — sits right in the clinical sweet spot
- Carlson Elite Omega-3 Gems (87/100): 1600mg total omega-3 (including 800mg EPA + 600mg DHA) — the highest dose in our top 6
- Moller's Omega-3 Liquid (80/100): 1200mg per 5ml teaspoon
- Solgar Triple Strength (79/100): 950mg EPA+DHA
- NOW Foods Ultra Omega-3 (83/100): 750mg EPA+DHA
- Life Extension Super Omega-3 (86/100): 700mg EPA+DHA + sesame lignans
One thing to watch: check the label for the EPA and DHA split, not just "total omega-3." Total omega-3 includes other fatty acids like ALA that aren't as well studied for the same benefits. Most research uses EPA-dominant or balanced EPA/DHA formulas.
