Source-based analysis, not hands-on testing. Our method
Cofounder of Superhuman Chambers · About the author. General information, not medical advice. No independent clinical review is claimed.
The verdict
Ultimate Omega 2X Sport is a high-dose lemon fish oil, with 2,150 mg of total omega-3s in two soft gels. It suits a drug-tested athlete, since NSF's own database lists it as Certified for Sport, with lot numbers. The catch is cost: about $681 a year at the Buy Once price, and Nordic's site lists only one size.
The trade-off
It costs about $1.87 a day (roughly $681 a year) at the suggested dose and Buy Once price, it contains fish and gelatin, and Nordic doesn't say whether it's in rTG or TG form.

About this price
The "Buy Once" price for the 60-count lemon soft gels on Nordic's product page, before tax. Subscribe & Save takes 10% off, to $50.36, and you can skip, modify or cancel at any time. That price isn't used here. Nordic says standard shipping is free on all orders.
A GOOD FIT FOR
A drug-tested athlete who wants about 2 g of EPA plus DHA from two soft gels a day, with a lot number to check against NSF's listing.
- An athlete subject to drug testing who wants a fish oil listed as NSF Certified for Sport
- An adult who wants a large omega-3 dose (2,150 mg total) in two soft gels a day
THINK TWICE IF
- Anyone avoiding fish or gelatin: it's fish oil from anchovies, sardines, mackerel and herring in a gelatin soft gel
- Anyone allergic to iodine or taking blood thinners, unless a physician has approved it: the label warning says to consult one first
- Anyone on a tight budget: at the suggested two soft gels a day and the Buy Once price, it's about $1.87 a day, or roughly $681 a year
What still needs checking
- Whether it's in rTG or TG form (Nordic's page names both for its fish oils)
- The soft gel's gelatin source
- Bottle size and net weight
- Whether opened bottles qualify for Nordic's 60-day satisfaction guarantee
- Who pays return shipping on nordic.com returns
- Results of Nordic's own third-party purity tests and its Friend of the Sea certification, which weren't checked independently

Nordic doesn't state a product warranty. Instead it offers a satisfaction guarantee: the original end-user purchaser can ask for a refund or replacement within 60 days of purchase (see returns).
ReturnsFor nordic.com orders, you have 30 days from receiving the order to request a return
For nordic.com orders, you have 30 days from receiving the order to request a return. You do that by getting a Return Authorization Number (RA#) from customer service by email or phone. The RA# must be marked on the outside of the package. For full credit, the return must arrive within 30 days of the RA# being issued. Nordic credits only products that are unmarked, resalable and in their original packaging. Defective products can be returned for a refund after a call to customer service. Nordic doesn't offer exchanges. The page doesn't say who pays return shipping or whether an opened bottle counts as resalable. The satisfaction guarantee is separate. It lets the original end-user purchaser ask for a refund or replacement within 60 days of purchase, for products bought in the US from Nordic or its authorized sellers. You generally go through the seller you bought from. Nordic may ask you to mail the product back for inspection at your own cost. The guarantee excludes unauthorized sellers and purchases from authorized sellers in other countries. It doesn't say whether opened bottles qualify.

Recorded recurring parts and refills:
- Ultimate Omega 2X Sport, 60 soft gels, lemon: $55.95 every 0.99 months. A 60-count bottle lasts 30 days (about 0.99 months) at the suggested two soft gels a day. The cost is the $55.95 Buy Once price. The 10% subscription price and tax aren't included.
- Annual refills at the suggested two soft gels a day: 730 soft gels / 60 per bottle x $55.95 = $680.73, at the Buy Once price. At the $50.36 Subscribe & Save price, the same year costs about $612.71. Tax isn't included, and Nordic says standard shipping is free.
- The first $55.95 bottle counts as the purchase, and refills cover three full years. So the three-year estimate ($55.95 + 3 x $680.73 = $2,098.14) includes about one bottle more than three years at the suggested dose (1,095 days, or 2,190 soft gels) would need.
Evidence & sources.
Do creatine, fish oil, vitamin D and magnesium work? Our evidence review grades the research as Mixed. That grade is about the claim, not about this product.
- CertificationNSF's Certified for Sport database lists Ultimate Omega 2X Sport (NUS-01807) by Nordic Naturals as a fish oil/omega softgel. The listing gives a package size of 60, a serving size of 2 softgels and 11 certified lot numbers. NSF's results for Nordic Naturals also show a second Ultimate Omega 2X Sport entry with no product code.23 Checked in NSF's own database, not just taken from the mark on Nordic's page. The listing shows no certification date and doesn't say what the program screens for. A sport certification is about what's in the product, not its health effects. You can match the lot number on your bottle to the listed lots.
- Manufacturer claimNordic's product page says the product is NSF Certified for Sport and that its fish oils are Friend of the Sea certified. It says its products are non-GMO and third-party tested, and that certificates of analysis are available for any product. The page makes structure/function statements for heart, brain, joint and muscle support. It says these statements haven't been evaluated by the FDA and that the product isn't intended to diagnose, treat, cure or prevent any disease.1 These are Nordic's own statements. The Friend of the Sea certification and the third-party test results weren't checked independently for this review. The page's benefit statements aren't evidence of a health effect.
- Published studyA 2021 meta-analysis pooled 7 randomized cardiovascular-outcome trials with 81,210 participants. Their mean age was 65, and the weighted average follow-up was 4.9 years. It found that marine omega-3 supplements were associated with a higher risk of atrial fibrillation (hazard ratio 1.25, 95% CI 1.07 to 1.46). The rise was larger in trials testing more than 1 g a day (HR 1.49, 95% CI 1.04 to 2.15). In trials testing 1 g a day or less, it was smaller (HR 1.12, 95% CI 1.03 to 1.22). Each extra 1 g a day was associated with an HR of 1.11.7 Summarized from the abstract as indexed by Europe PMC. The trials enrolled people for cardiovascular-outcome research and didn't test Ultimate Omega 2X Sport. The analysis looked only at atrial fibrillation, not at overall benefit or harm. Nordic's suggested two soft gels a day supply 2,150 mg of total omega-3s, above the 1 g a day split the analysis used.
