Core takeaway
- Two softgels: 1,125 mg EPA + 875 mg DHA (2,000 mg combined), 2,150 mg total omega-3, EPA:DHA about 1.29:1. That makes one softgel 1,000 mg of EPA + DHA.
- Amazon US price (October 12, 2026): $40.97 for 60 softgels, which is 30 servings.
- Real cost: $0.68 per 1,000 mg of EPA + DHA and $1.21 per 1,000 mg of EPA.
- Pack size matters: the 180-count pack at $104.60 works out to $0.58 per 1,000 mg of EPA + DHA, the lowest on the listing.
- Against regular Ultimate Omega: nearly the same cost per 1,000 mg ($0.68 vs $0.70), with about 1.8 times the EPA + DHA per serving.
Nordic Naturals Ultimate Omega 2X is the higher-strength version of one of the best-known fish oils in the US, and it is the same product we used in our Nordic Naturals vs Carlson comparison. This review looks at it on its own: what the Supplement Facts panel says, then what each 1,000 mg of EPA and DHA really costs at the Amazon US price.

What the Ultimate Omega 2X label says
| Amount per serving | Amount | % Daily Value |
|---|---|---|
| Calories | 25 | |
| Total fat | 2.5 g | 3% |
| Total omega-3s | 2,150 mg | Not established |
| EPA (eicosapentaenoic acid) | 1,125 mg | Not established |
| DHA (docosahexaenoic acid) | 875 mg | Not established |
Source: Supplement Facts panel on the Amazon US listing (60 count, Lemon), viewed October 12, 2026. The label notes the total includes EPA, DHA and other omega-3s in triglyceride form (rTG).
Ingredients on the label: purified deep sea fish oil (from anchovies, sardines, mackerel and herring), a softgel capsule (gelatin, glycerin, water, natural flavor), natural flavor, RRR-alpha tocopherol (antioxidant) and rosemary extract. The label states it contains no gluten, milk derivatives or synthetic dyes. Nordic’s own product page describes the oil as coming from wild-caught sardines and anchovies, so check the fish list on your bottle.
EPA plus DHA is 2,000 mg per serving, so 150 mg of the 2,150 mg total is other omega-3 that the label does not break out. Per softgel that is 562.5 mg of EPA and 437.5 mg of DHA, exactly 1,000 mg together.
Label math: the real cost per 1,000 mg
- Servings. The label serving is 2 softgels, and the 60-count bottle holds 30 servings.
- Total EPA in the bottle. 30 x 1,125 mg = 33,750 mg, or 33.75 g.
- Total DHA in the bottle. 30 x 875 mg = 26,250 mg, or 26.25 g.
- Total EPA + DHA in the bottle. 30 x 2,000 mg = 60,000 mg, or 60 g.
- Cost per 1,000 mg of EPA + DHA. $40.97 / 60 = $0.68.
Cost per 1,000 mg = price / (servings x mg per serving / 1,000)$40.97 / (30 x 2,000 / 1,000) = $40.97 / 60 = $0.68
- Cost per 1,000 mg of EPA. $40.97 / 33.75 = $1.21.
- Cost per 1,000 mg of DHA. $40.97 / 26.25 = $1.56.
- Cost per serving. $40.97 / 30 = $1.37.
Because one softgel is 1,000 mg of EPA + DHA, the $0.68 per softgel on the listing is also the cost per 1,000 mg. One caution on price: Amazon showed $40.97 as 23% off a $52.95 list price that day. At $52.95 the cost would be $0.88 per 1,000 mg of EPA + DHA, so recheck the price before you buy.
Which pack size is cheapest?
| Pack | Amazon US price | Servings | Per softgel (listing) | Per 1,000 mg EPA | Per 1,000 mg EPA + DHA |
|---|---|---|---|---|---|
| 60 count | $40.97 | 30 | $0.68 | $1.21 | $0.68 |
| 90 count | $62.00 | 45 | $0.69 | $1.22 | $0.69 |
| 120 count | $75.26 | 60 | $0.63 | $1.12 | $0.63 |
| 180 count | $104.60 | 90 | $0.58 | $1.03 | $0.58 |
The Supplement Facts panel was shown for the 60-count pack. Other rows assume the same per-softgel amounts, and per-softgel prices are as shown on the listing.
The first step up does not save anything: the 90-count pack costs a cent more per softgel than the 60-count ($0.69 vs $0.68). The savings start at 120 count ($0.63) and are largest at 180 count ($0.58).
Ultimate Omega 2X vs Ultimate Omega vs Thorne Super EPA vs AquaOmega 5X
| Product | Price and pack | Label serving | EPA | DHA | EPA:DHA | Per 1,000 mg EPA | Per 1,000 mg EPA + DHA | Per serving |
|---|---|---|---|---|---|---|---|---|
| Nordic Naturals Ultimate Omega 2X | $40.97, 60 softgels | 2 softgels | 1,125 mg | 875 mg | 1.29:1 | $1.21 | $0.68 | $1.37 |
| Nordic Naturals Ultimate Omega | $22.97, 60 softgels | 2 softgels | 650 mg | 450 mg | 1.44:1 | $1.18 | $0.70 | $0.77 |
| Thorne Super EPA | $41.00, 90 gelcaps | 1 gelcap | 425 mg | 270 mg | 1.57:1 | $1.07 | $0.66 | $0.46 |
| AquaOmega 5X Ultimate Strength | $42.00, 120 softgels | 4 softgels | 2,659 mg | 532 mg | 5:1 | $0.53 | $0.44 | $1.40 |
EPA and DHA come from each product’s Supplement Facts panel. EPA:DHA is label EPA divided by label DHA. Green marks the best value in a column.
Compared with the regular Ultimate Omega, the 2X costs $18.00 more per 60-count bottle but gives about 1.8 times the EPA + DHA per serving (2,000 mg vs 1,100 mg). The cost per 1,000 mg of EPA + DHA ends up almost the same, $0.68 against $0.70. The regular version is a hair cheaper per 1,000 mg of EPA ($1.18 vs $1.21) because the 2X carries relatively more DHA.
AquaOmega 5X Ultimate Strength is cheaper on every cost-per-1,000-mg measure in the table, and the 2X sits just above Thorne Super EPA on cost per 1,000 mg of EPA + DHA ($0.68 vs $0.66). In our head-to-head, the Carlson fish oil came to $0.47 per 1,000 mg of EPA + DHA on a 130-count pack at $42.42, so see the full comparison if cost per 1,000 mg is your priority. Label details for the others are in the Thorne Super EPA review and the AquaOmega High EPA review.
Pros and cons
Pros
- One softgel is 1,000 mg of EPA + DHA, so the math is easy and the listing’s per-softgel price equals the cost per 1,000 mg.
- Fewer softgels per gram: 4 softgels for 4 g, against about 7.3 for regular Ultimate Omega.
- $0.68 per 1,000 mg of EPA + DHA on the 60-count pack, falling to $0.58 on the 180-count pack.
- More DHA per serving (875 mg) than any other product in our table.
- The label states triglyceride form (rTG) and names the fish: anchovies, sardines, mackerel and herring.
Cons
- More expensive than AquaOmega 5X Ultimate Strength on every cost-per-1,000-mg measure ($0.68 vs $0.44 for EPA + DHA).
- $1.21 per 1,000 mg of EPA is above Thorne Super EPA ($1.07) and regular Ultimate Omega ($1.18).
- Softgel contains gelatin, so it is not vegetarian or vegan.
- The price on October 12 was a 23% discount, and at the $52.95 list price the cost is $0.88 per 1,000 mg of EPA + DHA.
- 150 mg of the total omega-3 is not broken out on the label.
Dose and safety
This is a high-potency label, so count carefully
One serving (2 softgels) gives 2,000 mg of EPA + DHA. At that amount, 4 g a day of EPA + DHA is 2 servings (4 softgels), and 5 g a day is 2.5 servings (5 softgels). Two servings a day already reaches the 4 g level.
The FDA has concluded that dietary supplements providing no more than 5 g per day of EPA and DHA combined are safe when used as recommended, and has said it cannot determine safety above that amount (FDA letter and NIH fact sheet). The NIH reports that two large trials using 4 g per day of omega-3 supplements for several years slightly increased the risk of atrial fibrillation (an irregular heartbeat) in people with or at high risk of cardiovascular disease. Talk to a doctor first if you take blood thinners, have a heart rhythm condition, or are pregnant. This post does not recommend a dose.
Verdict
A strong, simple label that is fairly priced rather than cheapest
Ultimate Omega 2X costs $0.68 per 1,000 mg of EPA + DHA at $40.97, and $0.58 in the 180-count pack. It gives about the same cost per 1,000 mg as the regular version while packing 2,000 mg into a serving, so you take fewer softgels.
It suits you if you want a high-potency, DHA-rich label and plan to buy a bigger pack. If you want the lowest cost per 1,000 mg, the label math points to AquaOmega 5X Ultimate Strength. If you avoid gelatin, this one is out. All figures are Amazon US prices from October 12, 2026.
