Carlson Elite Omega-3 Gems
Pros
- ✓No fishy aftertaste — natural lemon flavour consistently praised across reviews
- ✓High EPA/DHA concentration (800mg EPA + 600mg DHA) in superior rTG triglyceride form for better absorption
- ✓IFOS certified with independent third-party testing for purity, potency, and absence of heavy metals
- ✓Reviewers report noticeable results: improved skin, hair growth, clearer thinking, and reduced inflammation
Cons
- ✗Large softgel size — several reviewers note the capsules are big, though most find them easy to swallow
- ✗Can cause nausea or heartburn if taken on an empty stomach or both capsules simultaneously — best split across meals
- ✗Premium price point compared to standard fish oil products
- ✗One reviewer claimed a foam dissolution test suggested ethyl ester form, contradicting the rTG label claim — though this test is unreliable and product specs confirm rTG
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 Carlson Elite Omega-3 Gems vs NOW Foods Ultra Omega-...?
The key difference between these two comes down to form and price. Carlson's Elite Omega-3 Gems (£29.99, 87/100) use the re-esterified triglyceride (rTG) form, which research consistently shows absorbs better than the ethyl ester (EE) form used by NOW Foods' Ultra Omega-3 (£19.99, 83/100). Carlson also delivers more per serving — 800mg EPA and 600mg DHA versus NOW's 500mg EPA and 250mg DHA — meaning you're getting meaningfully more active fatty acids at the same one-to-two capsule dose. That difference in ingredient quality shows in the scores: 93/100 for Carlson versus 79/100 for NOW.
If budget is the main concern and you're happy taking your omega-3 with a meal containing fat (which improves EE absorption considerably), NOW is a reasonable option at £19.99 with its 85/100 value score. The enteric coating is genuinely useful if you've had trouble with fishy burps from other products. But if you want the most bioavailable option and can stretch to £29.99, Carlson is the better investment — especially for anyone focused on cardiovascular health who wants IFOS-certified purity and a natural lemon flavour rather than an enteric coating masking a less stable oil.
Both use large softgels, so if swallowing is a concern, neither has a clear edge there. Carlson's IFOS certification is more rigorous than NOW's GMP and GOED standards — useful if you're particular about third-party testing. NOW holds Kosher and Halal certification, which may matter to some buyers.
Carlson Elite Omega-3 Gems is a premium, professional-strength fish oil concentrate delivering 1,600 mg of omega-3s per two-softgel serving (800 mg EPA + 600 mg DHA) in the highly bioavailable rTG form, sourced from wild-caught Norwegian anchovies, sardines, and mackerel.

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.
