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
Moller's Omega-3 Liquid Lemon Flavour
Pros
- ✓IFOS 5-Star certified — the highest independent standard for fish oil purity and potency
- ✓Natural triglyceride form offers superior bioavailability compared to ethyl ester capsules
- ✓Liquid format removes capsule barriers, making it accessible for children and those with swallowing difficulties
- ✓Exceptionally clean formula — only cod liver oil, lemon flavour, and vitamin E as antioxidant
Cons
- ✗Premium pricing compared to capsule alternatives providing equivalent omega-3 content
- ✗Vitamin A content (250mcg/serving) requires monitoring total intake when combining with other supplements or multivitamins
- ✗Liquid form requires refrigeration after opening and has a shorter shelf life than encapsulated oil
- ✗Fish odour may still be perceptible despite lemon flavouring

What does the data say about NOW Foods Ultra Omega-... vs Moller's Omega-3 Liqui...?
Both products cost £19.99, but they take quite different approaches to delivering omega-3s. NOW Foods Ultra Omega-3 comes in softgels with 500mg EPA and 250mg DHA each, using an ethyl ester form — common and effective, but absorption is noticeably better when taken alongside a fatty meal. Moller's takes the liquid route, providing 1200mg of omega-3 per 5ml teaspoon in natural triglyceride form, which the body absorbs more readily regardless of what else you've eaten. That difference in form goes a long way to explaining why Moller's scores higher on ingredient quality (91.0 versus 79.0), while NOW Foods edges ahead overall (83.0 versus 80.0) largely due to its superior value score (85.0 versus 64.0).
If you want a no-fuss daily capsule that won't repeat on you — NOW Foods' enteric coating genuinely works for that — it's the practical pick for most adults, particularly those over 50 managing cardiovascular or joint health. Moller's suits people who struggle with large capsules, parents supplementing children, or anyone willing to pay a premium for IFOS 5-Star certified purity and better bioavailability.
One practical note: Moller's contains 250mcg of vitamin A per serving, so check your multivitamin before stacking them.
NOW Foods Ultra Omega-3 is a concentrated fish oil supplement delivering 500 mg EPA and 250 mg DHA per enteric-coated softgel, sourced from molecularly distilled anchovy, sardine, and mackerel oil.

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.
