How we evaluated it
Why we chose it What put it on our list
- NSF’s Certified for Sport directory lists Thorne Super EPA (EPA & DHA): gelcap, 90 count, one-gelcap serving, with 18 lot numbers shown. Thorne explains the mark as testing for the label claims and for nearly 300 banned substances.
- The label gives EPA and DHA separately: 425 mg EPA and 270 mg DHA in each gelcap, which is 695 mg.
- The label is short. The only other ingredients are mixed tocopherols (vitamin E) and a bovine gelatin gelcap with water and glycerin.
- Thorne says it tests each ingredient for identity, purity and potency, including heavy metals, pesticides and microbes. We found no results published.
Trade-offs What to weigh before you buy
- Thorne publishes no oxidation (TOTOX) figure and no lot report, and Thorne is not in IFOS’s registry. NSF’s program checks the label and banned substances; we could not confirm it tests freshness.
- The page says “sustainably sourced fish” but does not name the species or a sustainability certifier.
- The label directs one gelcap two to three times a day, which is 1,390 to 2,085 mg of EPA plus DHA. Our sources and dosing guide gives 250 to 500 mg a day for general health. Check with a clinician if you take blood thinners or have atrial fibrillation (see omega-3 and heart health).
- It costs about $0.36 per 500 mg of EPA plus DHA, roughly twice the budget IFOS-listed oils. The gelcap is bovine gelatin, so it is not vegetarian.
What to know Details worth knowing first
Thorne is a well-known supplement maker, and Super EPA is one of its best-selling products. What sets it apart in this category is the NSF Certified for Sport listing, which tests a product against its label and for substances banned in sport and lists the lots in a public directory.
What we could not find is anything about freshness. Fish oils oxidize, and the programs that publish a TOTOX figure for each lot (IFOS, for example) do not list Thorne. NSF’s listing is useful, but it is not a freshness report. Thorne also does not name its fish or a sustainability certifier.
That leaves a fish oil with a clear label and a respected certification, but less evidence on freshness and source than the IFOS-listed options. Our guide to sources and dosing explains the forms and doses.
Quality & testing How it measures up against our checklist

- NSF (Certified for Sport)
| What we checked | What we found |
|---|---|
| Independent testing (NSF Certified for Sport) Verified | Listed in NSF’s directory as Thorne Super EPA (EPA & DHA): gelcap, 90 count, 18 lots. Not in the IFOS registry. |
| Freshness (TOTOX at or under 26) Not verified | No oxidation figure on Thorne’s page and no lot report found. |
| Stated EPA and DHA Maker’s claim | 425 mg EPA and 270 mg DHA per gelcap, from Thorne’s ingredient table. We did not see a lot test of the amounts. |
| A named source Not verified | “Sustainably sourced fish”. No species, region or certifier is named. |
| Lot or best-by date Maker’s claim | Thorne’s page does not show a date. Vitacost lists best-by dates for the bottles it ships. |
| Smell and taste Not verified | We have not handled a bottle. |
What the labels mean
- Verified We opened an independent record that confirms it: a certifier’s listing, a regulator’s list or a lab report. It is linked under Sources.
- Maker’s claim The maker says so on its own page or label. We read it but found no independent record.
- Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.
Sources Where our facts come from
Where to buy Other stores and the prices we saw
- Vitacost approx. $41 to $45 for 90 gelcaps; approx. $80 for 180. Vitacost has two listings for the 90-count bottle at different prices. It says it buys from brands or authorized distributors.
Prices as we saw them on October 22, 2026. They change often. These links carry no tracking code and earn us nothing.
Alternatives Other options to compare
- Momentous Omega-3 Also NSF Certified for Sport, and also in IFOS, with an oxidation figure we could read. Higher dose: 1,600 mg per two softgels.
- Sports Research Alaskan Omega-3 Fish Oil Costs about half as much per 500 mg, with an IFOS lot report and a named source (Alaska pollock).
