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 does the data say about WHC UnoCardio 1000 vs NOW Foods Ultra Omega-...?
These two fish oils sit at opposite ends of the quality-versus-value spectrum, and the difference starts with the oil itself. WHC UnoCardio 1000 uses triglyceride-form omega-3, which is how fish oil occurs naturally and how your body absorbs it most efficiently. It delivers 1000mg of EPA and DHA in a single softgel, alongside 1000 IU of vitamin D3 — making it genuinely two supplements in one. NOW Foods Ultra Omega-3 uses ethyl ester form, which absorbs less efficiently unless taken with a fatty meal. Its dose is 750mg EPA and DHA per softgel (500mg EPA, 250mg DHA), which is still respectable, and the enteric coating is a practical touch that effectively prevents the fishy aftertaste many people find off-putting with standard fish oils.
If purity and potency are your priority and budget isn't a concern, WHC is the stronger product. Its IFOS 5-star certification and Labdoor number-one ranking are the most rigorous third-party validations available for fish oil, and that ingredient quality score of 100/100 reflects it. At £26.95 it scores just 60 on value, so you're paying a meaningful premium. NOW Foods at £19.99 scores 85 on value and suits anyone who wants solid daily omega-3 support without spending heavily — particularly people who've struggled with fishy burps from other supplements.
Practically speaking, NOW's enteric-coated softgels are on the larger side, so anyone with swallowing difficulties may find them awkward. WHC's single softgel is simpler to take but should ideally be had with food to maximise absorption given its triglyceride form. NOW carries Kosher, Halal, Non-GMO, and GOED certifications — useful if those matter to you. Both are third-party tested, so neither involves a leap of faith on quality claims.
WHC UnoCardio 1000 is a premium Belgian-made omega-3 supplement that has been ranked #1 by independent testing lab Labdoor and holds IFOS 5-star certification.

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.
