Best For
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

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.
