Life Extension Super Omega-3 EPA...

Pros

  • IFOS 5-star certified fish oil — independently verified for purity and potency, a gold standard in the category
  • Added sesame lignans and olive polyphenols enhance antioxidant stability and cardiovascular support beyond basic fish oil
  • Minimal fishy aftertaste reported by most users — capsules rated as fresh and neutral
  • Efficient dosing: reviewers note fewer capsules needed per day compared to lower-concentration competitors

Cons

  • Capsules described as large by some users, which can make swallowing uncomfortable
  • Price point is higher than basic fish oil brands — a noted drawback versus competitors like Now Foods Ultra Omega-3
  • Occasional mild fish smell reported, particularly in certain batches or after prolonged storage
  • Standard serving of 4 capsules daily may feel burdensome for those preferring a 1-2 capsule routine

Best For

Adults seeking clinically relevant EPA/DHA doses for cardiovascular support People with elevated triglycerides or cholesterol looking for adjunct supplementation Those who have had negative experiences with low-quality fish oils (fishy burp, rancidity) Pregnant or breastfeeding women needing reliable DHA intake (consult physician) Over-50s focused on brain health, joint comfort, and inflammation management Supplement-aware consumers who prioritise third-party certification over price

NOW Foods Ultra Omega-3 500 EPA ...

Pros

  • Enteric coating reliably eliminates fishy burps and aftertaste — the most frequently cited advantage across dozens of reviews
  • High potency 500/250 mg EPA/DHA per single softgel reduces the number of capsules needed compared to standard fish oil products
  • Molecularly distilled for heavy metal removal; GMP, Non-GMO Project Verified, GOED Omega-3 member, Kosher and Halal certified
  • Multiple reviewers report real-world outcomes: reduced joint stiffness, improved focus, skin and hair improvements, and improved blood lipid panels

Cons

  • Ethyl ester form rather than the superior triglyceride form — absorption may be meaningfully lower without dietary fat at time of dosing
  • Softgels are on the larger side; some users flag swallowing difficulty despite their soft, gel texture
  • A minority of reviewers note residual digestive fishy odour (from stomach, not burping) and recommend taking with a fat-containing meal or refrigerating the bottle
  • Some iHerb reviews are clearly off-topic or low-information (emoji-only, unrelated product descriptions), slightly reducing the usable review signal

Best For

Adults over 50 focused on cardiovascular and joint health maintenance People sensitive to fishy aftertaste or burping from standard fish oil capsules Those seeking high-potency EPA/DHA from a single daily softgel Individuals who eat little or no oily fish and need a reliable dietary source of omega-3 Active adults looking for inflammation and recovery support after exercise

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.
