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

Triple Strength Omega-3 100 Soft...

Pros

  • ✓Very high EPA+DHA concentration (950 mg per softgel) — effectively triple a standard fish oil dose in one capsule
  • ✓Minimal fishy aftertaste or burping reported by the majority of reviewers when taken with food
  • ✓Broad user-reported benefits: improved hair, skin, nails, joint comfort, mood, and cardiovascular markers
  • ✓Molecularly distilled to remove mercury and other heavy metals; non-GMO, gluten- and dairy-free

Cons

  • ✗Capsules are notably large — several reviewers mention this, though most still find them manageable to swallow
  • ✗Child-proof bottle cap reported as excessively difficult to open by multiple Amazon reviewers
  • ✗Not third-party tested (no NSF, USP, or Informed Sport certification listed); no independent purity verification
  • ✗Contains fish gelatin — not suitable for vegetarians, vegans, or those requiring halal/kosher certification; allergen list also includes hazelnuts and mustard

Best For

Adults who eat little or no oily fish and need to supplement EPA and DHA People seeking cardiovascular and cholesterol support Those targeting hair, skin, and nail improvements Adults over 40 managing joint health or mild inflammation Anyone wanting a high-potency single-capsule omega-3 rather than multiple standard-dose pills Pregnant or breastfeeding women (under medical guidance) needing DHA support

What does the data say about NOW Foods Ultra Omega-... vs Triple Strength Omega-...?

The key difference between these two comes down to form, price, and verification. NOW Foods Ultra Omega-3 delivers 500mg EPA and 250mg DHA per softgel using an ethyl ester form — functional but not optimal unless taken with a fatty meal. Its enteric coating is the headline feature, reliably preventing the fishy burps that put many people off fish oil. At £19.99 and a score of 83/100, it represents genuinely good value. Solgar's Triple Strength packs 950mg of combined EPA and DHA per capsule — considerably more per dose — and scores higher on ingredient quality at 87/100, though the brand hasn't published third-party testing results and the price of £36.95 pushes the value score down to 68/100.

If you're after a well-verified, everyday omega-3 that sits comfortably in a monthly budget, NOW Foods makes more sense. The third-party testing, GOED membership, and Non-GMO Project certification provide meaningful reassurance, and the enteric coating matters if you've had bad experiences with fish oil repeating on you. It's a sensible pick for anyone over 50 managing heart or joint health who wants one capsule a day without the aftertaste.

Solgar suits those who want maximum EPA and DHA per capsule and are willing to pay a premium. The higher dose makes it appealing if you're under GP advice to hit a specific omega-3 target, or if you simply want fewer capsules. That said, the absence of third-party certification is worth noting, particularly at this price point. Both products come in large softgels, so if swallowing is a concern, neither has a clear edge — though NOW's softer gel texture may help slightly.

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.
