The Best Fish Oil Supplements in NZ
1. GO Healthy GO Fish Oil 1500mg – Best overall
GO Healthy’s GO Fish Oil 1500mg is a high potency fish oil sourced from deep sea wild fish, molecularly distilled and mercury tested to ensure purity, with each capsule containing 50% more omega-3 than GO Healthy’s standard 1,000mg formula.
It’s positioned as a general health and wellbeing supplement, supporting healthy skin, heart health, brain function and joint health, making it a sensible everyday choice rather than a specialised formula.
At 175 capsules per bottle and a straightforward dosage, it’s the pick most people should start with before considering a higher-strength or more specialised option.
Pros
- 1,500mg high potency dose
- Molecularly distilled and mercury tested
- 50% more omega-3 than GO Healthy’s standard formula
Cons
- Not odourless – some people notice fishy aftertaste or burps with standard capsules
- 175-capsule bottle needs replacing more often than the larger packs on this list
Key specs: 1,500mg fish oil per capsule, 175 capsules, deep sea wild fish sourced, molecularly distilled, mercury tested.
2. GO Healthy GO Fish Oil 2000mg – Best higher-strength
This is GO Healthy’s higher-strength 2,000mg fish oil, aimed at anyone wanting a more concentrated dose than the standard 1,500mg option without switching to a different brand or formula style.
It’s odourless, addressing the most common complaint about fish oil supplements generally, and comes in a large 200-capsule bottle.
The dosage is flexible at 1-3 softgel capsules daily, best taken with food, letting you adjust intake up or down depending on your needs.
Pros
- Higher 2,000mg strength than GO Healthy’s standard formula
- Odourless formula
- Large 200-capsule bottle
Cons
- Higher strength isn’t necessary for everyone – check with a healthcare professional if unsure what dose you need
- Costs more upfront than the standard 1,500mg option
Key specs: 2,000mg fish oil per capsule, 200 capsules, odourless, 1-3 capsules daily dosage.
3. GO Healthy GO Fish Oil Odourless 2000mg – Best odourless / value
This is GO Healthy’s dedicated odourless formula at 2,000mg strength, specifically marketed on being mercury tested and New Zealand made, for anyone who has avoided fish oil in the past due to fishy burps or aftertaste.
At 230 capsules per bottle, it’s the largest capsule count on this list, and priced lower than several other picks despite the larger pack size and higher strength.
Like the other GO Healthy picks, dosage is flexible at 1-3 capsules daily, best taken with food.
Pros
- Genuinely odourless formula addresses fish oil’s most common complaint
- 230 capsules is the largest pack size on this list
- Competitively priced despite the larger pack and higher strength
Cons
- No added ingredients like Vitamin D or antioxidants found on some other picks
- 2,000mg may be more than some people need for general maintenance
Key specs: 2,000mg fish oil per capsule, 230 capsules, odourless, New Zealand made, mercury tested.
4. Clinicians Omega-3 Fish Oil 1500mg – Best Clinicians brand
Clinicians is a well-known New Zealand supplement brand, and this 1,500mg omega-3 fish oil is marketed specifically around joint and mobility support, mental clarity and mood, and heart health and circulation.
At 200 capsules per bottle, it’s a solid mid-size pack that should last several months at a standard daily dose.
It’s a straightforward, no-frills fish oil from a trusted brand rather than a specialised or higher-strength formula, making it a sensible alternative to the GO Healthy range above.
Pros
- Well-known, trusted NZ supplement brand
- Marketed around joint, mood and heart health specifically
- 200-capsule bottle at a competitive price
Cons
- Standard 1,500mg strength – not a higher-potency option
- No added Vitamin D or other bonus ingredients
Key specs: 1,500mg fish oil per capsule, 200 capsules, supports joints, mood and heart health.
5. Nutra-Life Fish Oil One-A-Day – Best one-a-day convenience
Nutra-Life’s One-A-Day formula is built around simplicity – just one capsule daily with food and a glass of cold water, rather than the 1-3 capsule range most other fish oil supplements on this list require.
At 90 capsules per bottle, it covers roughly three months of daily use, a shorter supply than the larger GO Healthy and Clinicians packs but matched to its simpler single-capsule dosage.
This is the pick best suited to anyone who wants a fish oil habit that’s as low-effort as possible, without needing to think about adjusting daily capsule counts.
Pros
- Genuinely one capsule daily – no need to count out multiple capsules
- Straightforward dosage instructions
- Smaller bottle size suits trying the brand before committing to a bigger pack
Cons
- 90 capsules is a shorter supply than the larger packs on this list
- Single fixed dose offers less flexibility to adjust intake
Key specs: One capsule daily dosage, 90 capsules, take with food and water.
6. Nutra-Life Fish Oil 1500mg Plus Vitamin D – Best with added Vitamin D
This Nutra-Life formula combines a standard 1,500mg fish oil dose with added Vitamin D in the same capsule, covering two common supplement needs – omega-3 and Vitamin D – without needing to take two separate products.
The recommended adult dosage is 2 capsules daily, and the 180-capsule bottle covers around three months of use at that rate.
This is a sensible pick for anyone already planning to take a Vitamin D supplement (common in NZ over winter months) who’d rather combine it with their fish oil than take two separate pills.
Pros
- Combines fish oil and Vitamin D in one capsule
- 180-capsule bottle at a reasonable price
- Useful for anyone in NZ supplementing Vitamin D over winter
Cons
- 2-capsule daily dose means going through the bottle faster than a one-a-day formula
- Fixed Vitamin D dose – not adjustable separately from the fish oil dose
Key specs: 1,500mg fish oil plus Vitamin D per serve, 180 capsules, 2 capsules daily dosage.
7. GO Healthy PRO EPA/DHA Advanced – Best high-potency EPA/DHA
This is GO Healthy’s advanced formula, concentrated to 1,350mg of fish omega-3 triglycerides per capsule, providing 540mg of EPA and 405mg of DHA specifically – the two individual omega-3 fatty acids most associated with fish oil’s health benefits.
It also includes Vitamin D3 (250IU) and Vitamin E in the same softgel capsule, adding two further nutrients beyond straight omega-3s.
For anyone who wants to compare fish oils by actual EPA and DHA content rather than just total fish oil milligrams, this is the pick with the clearest breakdown of both figures.
Pros
- Clear EPA (540mg) and DHA (405mg) breakdown, not just a total fish oil figure
- Includes Vitamin D3 and Vitamin E in the same capsule
- Positioned as GO Healthy’s advanced, higher-concentration formula
Cons
- Smaller 120-capsule count than several other picks on this list
- Higher price reflects the more concentrated, multi-ingredient formula
Key specs: 1,350mg fish omega-3 triglycerides (540mg EPA, 405mg DHA), plus Vitamin D3 and Vitamin E, 120 capsules.
8. Blackmores Omega Triple – Best international brand
Blackmores is a well-known Australian supplement brand, and this Omega Triple formula contains three times the omega-3s of a standard fish oil capsule, in an odourless, vanilla-flavoured softgel so you take fewer capsules for the same omega-3 intake.
It’s extracted from 100% wild-caught small fish, and is marketed specifically at people who don’t eat the recommended two servings of fish per week, providing EPA and DHA for joint, heart, eye, brain and skin health.
The vanilla flavouring and odourless design are a genuine point of difference from the plain GO Healthy and Clinicians capsules on this list, aimed at anyone who dislikes the taste or smell of standard fish oil.
Pros
- 3x the omega-3 concentration means fewer capsules for the same intake
- Odourless, vanilla-flavoured capsules
- Well-known international brand, wild-caught small fish sourced
Cons
- Smaller 75-capsule count reflects its concentrated, fewer-capsules-needed design
- Vanilla flavouring won’t appeal to everyone
Key specs: 3x standard omega-3 concentration, odourless vanilla-flavoured capsules, 75 capsules, wild-caught small fish sourced.
9. About Health Lester’s Oil – Best premium multi-ingredient formula
Lester’s Oil is a genuinely different formula to the other picks on this list – backed by a human study conducted at a New Zealand university, it contains more omega-3 than standard formulas in the same size softgel, plus five additional ingredients: Vitamin D, Co-Enzyme Q10, Lutein, Zeaxanthin and Astaxanthin at therapeutic doses.
The manufacturer states every batch is independently lab tested at a government-owned laboratory for potency and quality, and that Lester’s Oil has consistently exceeded its own label claim for omega-3 levels.
This is the premium pick on this list for anyone wanting a broader multi-ingredient antioxidant formula rather than a straightforward fish oil, and it’s priced accordingly.
Pros
- University-study-backed formula with independent government lab testing
- Five added ingredients (Vitamin D, CoQ10, Lutein, Zeaxanthin, Astaxanthin) beyond plain omega-3
- Manufacturer states it consistently exceeds its own label claim for omega-3 potency
Cons
- Highest price per capsule of any pick on this list
- 60-capsule bottle is one of the smaller pack sizes here
Key specs: Concentrated omega-3 plus Vitamin D, CoQ10, Lutein, Zeaxanthin and Astaxanthin, 60 capsules, independently lab tested.
10. GO Healthy GO Krill Oil 1500mg – Best krill oil alternative
This is a krill oil, not a fish oil – a genuinely different marine-oil source worth knowing before buying, where the omega-3s are naturally bound to phospholipids, which GO Healthy states helps support more efficient absorption into body cells than standard fish oil.
It naturally contains EPA and DHA omega-3 fatty acids, supporting heart health, healthy cholesterol balance, mental clarity and general vitality, similar territory to the fish oil picks above but via a different source oil.
At just 30 capsules per bottle, it’s priced and packaged as a specialised alternative rather than a everyday bulk supplement, worth considering if standard fish oil hasn’t suited you or you’re curious about krill oil specifically.
Pros
- Phospholipid-bound omega-3s may support more efficient absorption, per the manufacturer
- A genuine alternative if standard fish oil hasn’t agreed with you
- Naturally contains EPA and DHA
Cons
- This is krill oil, not fish oil – a different product, not simply a stronger fish oil
- Only 30 capsules per bottle at a price similar to much larger fish oil packs on this list
Key specs: 1,500mg krill oil per capsule, phospholipid-bound omega-3s, naturally contains EPA and DHA, 30 capsules.
How to choose the best fish oil supplement for you
With so many fish oil formulas on the market, a few genuine factors matter more than brand name alone when deciding which one is actually right for you.
EPA and DHA content
EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are the two specific omega-3 fatty acids responsible for most of fish oil’s health benefits, and they’re not always broken out separately on the label – some products just list a total fish oil milligram figure. Where a product does list EPA and DHA individually, like the GO Healthy PRO EPA/DHA pick above, it’s easier to compare like-for-like against other supplements.
Source and quality testing
Look for fish oil sourced from wild-caught, cold-water fish, and check whether it’s mercury tested and molecularly distilled – both are genuine purity indicators rather than marketing language, and several picks on this list (the GO Healthy range in particular) state both explicitly.
Odour and capsule form
Fishy aftertaste and burps are the most common reason people stop taking fish oil. An odourless formula, like the GO Healthy Odourless pick or Blackmores’ vanilla-flavoured capsules, is worth the small price premium if this has put you off fish oil before.
Added ingredients
Some fish oil supplements combine omega-3s with other nutrients in the same capsule – Vitamin D is the most common addition, but formulas like Lester’s Oil go further with CoQ10, Lutein, Zeaxanthin and Astaxanthin. These combination formulas cost more per capsule but save you taking a separate supplement if you’d be buying those nutrients anyway.
Dosage and pack size
Check both the recommended daily dose (one capsule versus two or three) and the total capsule count, since the two together determine how long a bottle actually lasts and the real cost per month, not just the shelf price.
Anyone building out a broader supplement routine might also want to check our guides to omega-3 supplements, multivitamins and probiotics.
Verdict
For most people, GO Healthy’s GO Fish Oil 1500mg is the easiest everyday recommendation – a high potency, mercury-tested formula from a trusted NZ brand. If fishy aftertaste has put you off fish oil before, the GO Healthy Odourless pick or Blackmores Omega Triple are both genuinely odourless alternatives.
Anyone wanting to compare supplements by actual EPA and DHA content should look at the GO Healthy PRO EPA/DHA Advanced formula, while anyone wanting a broader antioxidant formula beyond plain omega-3 should consider Lester’s Oil. If standard fish oil hasn’t agreed with you, the GO Healthy Krill Oil is worth trying as a genuinely different source – just remember it’s krill, not fish, oil.
Frequently Asked Questions
What’s the difference between fish oil and omega-3?
Omega-3 is the general name for a family of essential fatty acids, while fish oil is one specific source of it – primarily EPA and DHA. Other omega-3 sources include krill oil (a different marine source) and plant-based options like flaxseed or algae oil, which contain a different type of omega-3 (ALA) that the body converts less efficiently into EPA and DHA.
What’s the best time of day to take fish oil?
Fish oil is generally best taken with a meal containing some fat, which helps with absorption and reduces the chance of fishy aftertaste or an upset stomach. Many people find taking it with their largest meal of the day works well, but consistency day-to-day matters more than the specific time.
How much fish oil should I take daily?
This varies by product and individual needs, so always follow the dosage on the specific product’s label or a healthcare professional’s advice rather than a generic figure. Most of the products on this list recommend somewhere between 1 and 3 capsules daily depending on their individual strength.
Why is my fish oil supplement giving me fishy burps?
This happens when capsules break down too quickly in the stomach, releasing oil before it’s properly digested. Odourless formulas (like several picks on this list) use additional processing to reduce this, and taking fish oil with food, or trying a different brand, can also help.
Is krill oil better than fish oil?
Krill oil’s omega-3s are naturally bound to phospholipids, which some research suggests may support more efficient absorption than standard fish oil, but it typically comes in smaller doses per capsule and at a higher price. Neither is definitively “better” for everyone – it often comes down to whether standard fish oil agrees with you.
Can I take fish oil with other supplements or medication?
Fish oil can interact with blood-thinning medication and some other supplements, so it’s worth checking with a pharmacist or doctor before combining it with prescription medication, particularly anticoagulants, or before any planned surgery.
