Thorne Super EPA vs Sports Research Omega-3

The short answer: Sports Research for value, Thorne for certification

Both are concentrated fish oils from established brands. They differ on price, form and the seal on the bottle.

• Sports Research Triple Strength is best for most buyers: one softgel a day, 950 mg EPA plus DHA, triglyceride form, IFOS 5-star, about $0.37 per 1,000 mg.
• Thorne Super EPA is best for drug-tested athletes and anyone who wants NSF Certified for Sport, at about $0.72 per 1,000 mg.
• Our pick for most buyers is Sports Research, because it delivers more EPA and DHA per capsule, in the more bioavailable form, for half the cost per milligram.
• The disclaimer: this comparison is built from both brands' pages and the NIH Office of Dietary Supplements fact sheet, read October 21, 2026. We do not test supplements ourselves.

Dose: Sports Research packs 37% more EPA plus DHA into each capsule

One Sports Research softgel lists 950 mg of EPA plus DHA. One Thorne gelcap lists 695 mg. That is 255 mg more, or about 37% more, per capsule by our arithmetic.

The split differs. Sports Research is heavier on EPA, 690 mg against Thorne's 425 mg. DHA is nearly level, 260 mg against 270 mg.

The labels also suggest different daily amounts. Sports Research says one softgel a day. Thorne says one softgel two to three times a day, so 1,390 to 2,085 mg of EPA plus DHA.

There is no official recommended intake for EPA and DHA in the US, per ODS. One capsule of either is a reasonable starting point for a low-fish diet; more is a question for a clinician.

Price: Sports Research costs about half as much per milligram

Thorne lists $45.00 for 90 gelcaps. Sports Research lists $31.63 for 90 softgels. Both checked October 21, 2026.

Per capsule, that is $0.50 against about $0.35. Per 1,000 mg of EPA plus DHA, it is about $0.72 against $0.37, so Thorne costs roughly twice as much for the same amount of omega-3.

At each label's suggested use, the daily cost gap widens. Sports Research at one softgel costs about $0.35 a day. Thorne at two to three gelcaps costs $1.00 to $1.50 a day.

Subscriptions narrow nothing: Thorne takes 10% off, to $40.50, and Sports Research takes 15%, to $26.89.

A year at each label's suggested use: about $128 against $365 to $548

Annual cost is where the per-capsule gap becomes hard to ignore. Every figure below is our arithmetic from list and subscription prices checked October 21, 2026.

• Sports Research, one softgel a day: about $128 a year at $31.63 per 90, or about $109 on subscription.
• Thorne, two gelcaps a day: $365 a year at $45.00 per 90, or about $329 on subscription.
• Thorne, three gelcaps a day: about $548 a year at list, or about $493 on subscription.
• Matched for EPA plus DHA: two Thorne gelcaps give 1,390 mg a day; Sports Research would need about one and a half softgels for the same amount, still well under $200 a year at list.

Form: triglycerides absorb somewhat better, but both work

Thorne uses ethyl esters. Sports Research uses re-esterified triglycerides.

ODS states that re-esterified triglycerides, natural triglycerides and free fatty acids have somewhat higher bioavailability than ethyl esters, citing Dyerberg and colleagues in 2010 (PMID 20638827). In the same passage, ODS says all forms significantly increase blood EPA and DHA.

That makes form a tie-breaker, not a deal-breaker. It nudges the comparison further toward Sports Research, which already wins on dose and price.

Both labels direct taking the capsules as suggested; Sports Research specifies with food. Taking any fish oil with a meal that contains fat is consistent with how fats are absorbed.

Certification: only Thorne screens for banned substances

This is the one category Thorne wins outright.

Thorne Super EPA carries NSF Certified for Sport. Thorne states each certified batch is tested for label claims and for nearly 300 substances banned by many major athletic organisations.

Sports Research lists IFOS 5-Star, an independent programme for fish oil purity, potency and freshness, plus MSC sustainability and IGEN non-GMO marks. None of those screen for banned substances.

For a recreational buyer, IFOS covers the questions that matter most in fish oil: contaminants, oxidation and whether the label dose is in the bottle. For a tested athlete, only NSF Certified for Sport or an equivalent will do.

Our explainer on what third-party supplement seals actually verify covers each mark. Read the full Thorne Super EPA review for Thorne's testing wording.

Convenience: one softgel a day beats two or three

Sports Research asks for one softgel a day. A 90-count bottle lasts three months.

Thorne's label asks for two or three a day. A 90-count bottle lasts 30 to 45 days, so you reorder two or three times as often.

Pill count matters for adherence, especially for people already taking other supplements such as Thorne Magnesium CitraMate or a creatine powder. Fewer capsules means fewer missed doses.

Ingredients and allergens: different shells, different fish

Thorne lists fish oil, vitamin E as mixed tocopherols, and a softgel of bovine gelatin, purified water and glycerin. It also lists Gluten Free, Dairy Free and Soy Free. The page does not name the fish species.

Sports Research lists wild Alaska pollock oil, tocopherols, and a softgel of tilapia-sourced fish gelatin, vegetable glycerin and purified water.

Pescatarians who avoid beef should choose Sports Research. Anyone with a specific fish allergy should check both labels with an allergist, since neither product is fish-free.

Evidence and safety: the same for both

The research applies to fish oil generally, not to either brand.

In VITAL (PMID 30415637), an omega-3 supplement did not significantly reduce major cardiovascular events over a median 5.3 years, though total heart attacks were 28% lower.

A 2020 Cochrane review of 86 trials (PMID 32114706) found triglycerides fell by about 15%, with no effect on all-cause mortality or stroke.

ODS lists common side effects as mild: unpleasant taste, bad breath, heartburn, nausea and stomach upset. It notes fish oil might prolong clotting with warfarin (PMID 14742793), and that 4 g a day for years slightly raised atrial fibrillation risk in people with heart disease.

Neither product is close to 4 g at its label dose. Talk to a clinician before starting either, especially if you take a blood thinner or have a heart rhythm condition.

What buyers report

Both brands showed a 4.7 average on their own sites on October 21, 2026: Thorne from 386 reviews and Sports Research from 1,927.

Both pages carry AI-generated summaries that highlight quality and the absence of fishy aftertaste. Seller-hosted reviews and seller-run summaries skew positive, so we give them no weight in the decision.

Sourcing: Sports Research names its fish, Thorne names its process

Sports Research states its oil is single-source wild Alaska pollock, MSC certified sustainable and traceable, and refined in a 10-step process to EPA and DHA concentrations of 80 to 85%.

Thorne states its oil comes from sustainably sourced cold-water fish under sustainable harvesting practices, and that molecular distillation removes contaminants including PCBs and heavy metals. Its page does not name the species.

For buyers who track fishery certification, Sports Research gives more to check. For buyers focused on contaminants, both describe a purification step, and IFOS on the Sports Research bottle adds independent contaminant testing.

What neither label tells you

Some useful figures are missing from both pages, as read October 21, 2026.

• Oxidation values: neither page prints peroxide, anisidine or TOTOX figures for the current lot, the numbers that show freshness
• A named baseline for marketing claims: Sports Research's three-times-the-strength claim does not say what it compares against
• Fish species for Thorne: the page says cold-water fish without naming them
• Total omega-3 for Thorne: the panel shown lists EPA and DHA but no total omega-3 line

Which one for which buyer

A few common situations, mapped to the documented differences.

• A runner or lifter in a tested sport: Thorne, for NSF Certified for Sport
• A budget-minded adult who eats little fish: Sports Research, at about $0.35 a day
• Someone already taking several pills: Sports Research, at one softgel a day
• A pescatarian who avoids beef: Sports Research, whose shell is fish gelatin
• Anyone on warfarin, pregnant, or with a heart rhythm condition: neither until a clinician has reviewed it
• A vegetarian or vegan: neither; both are fish products

How we compared them

We read each brand's product page and supplement facts on October 21, 2026, and the NIH Office of Dietary Supplements omega-3 fact sheet, updated August 22, 2025. Trials are cited by PubMed ID.

Per-capsule and per-milligram costs are our arithmetic from list prices, not discounted or subscription prices unless stated. Where one label prints a figure and the other does not, we report the gap rather than estimate.

We do not test supplements ourselves, and nothing here is medical advice.

Choose Thorne if, choose Sports Research if

For most buyers the decision is quick.

• Choose Sports Research Triple Strength if you want the most EPA and DHA per capsule and per dollar, in triglyceride form, at one softgel a day.
• Choose Sports Research if you avoid beef gelatin.
• Choose Thorne Super EPA if you are a drug-tested athlete or compete under a sports body that recognises NSF Certified for Sport.
• Choose Thorne if you already buy Thorne products, such as Thorne creatine, and value one trusted brand over cost.
• Consider a liquid instead if capsules are the problem; Carlson The Very Finest Fish Oil lists 1,300 mg EPA plus DHA per teaspoon. Read the Carlson review.
• Consider Nordic Naturals if you prefer a lemon-flavoured soft gel; read the Ultimate Omega review.

Where fish oil fits

Fish oil appears in our supplements with the best evidence guide, mainly for people who eat little oily fish. Two servings of fish a week remain the food-first alternative.

Our budget athlete's supplement stack applies a cost-per-effective-dose test, which is the test Sports Research wins here.

Bottom line

Sports Research Triple Strength wins this comparison for most people: 37% more EPA plus DHA per capsule, the more bioavailable triglyceride form, one softgel a day and about half the cost per milligram, as listed in October 2026.

Thorne Super EPA wins one category that matters a great deal to one group: NSF Certified for Sport. If you are tested, pay the premium. If you are not, the cheaper bottle is the better fish oil on every documented measure.
