What’s the difference between Nordic Naturals and Sports Research?
Both use the better-absorbed triglyceride form, so the differences are dose shape and serving size. Nordic Naturals delivers 1,280 mg of omega-3 across two softgels, balanced at 650 mg EPA and 450 mg DHA, with per-lot certificates of analysis and Friend of the Sea certification. Sports Research delivers a concentrated one-a-day softgel: 1,250 mg fish oil with ≥1,040 mg omega-3, EPA-weighted (about 690 mg EPA), with an IFOS 5-star rating and MSC sustainability certification.
Ingredient breakdown: Nordic Naturals vs Sports Research
Dose and ratio. Nordic offers a balanced EPA/DHA split over two softgels; Sports Research packs comparable omega-3 into one EPA-weighted softgel — convenient, and EPA-forward. Form. Both triglyceride, both well absorbed. Testing. Different but strong programs: Nordic publishes per-lot COAs you can look up; Sports Research carries an IFOS 5-star rating (an omega-3-specific third-party standard). Both address purity and freshness credibly.
Who should choose Nordic Naturals vs Sports Research?
Choose Nordic Naturals if you want a balanced EPA/DHA profile, value per-lot COA transparency, and don’t mind a two-softgel serving. Choose Sports Research if you prefer a concentrated one-a-day softgel, want IFOS 5-star verification, or lean toward an EPA-weighted formula.
Who should be careful: omega-3s can interact with blood thinners. If you take anticoagulants or have a bleeding disorder, talk to a healthcare professional first. This comparison is educational — not medical advice.

Nordic Naturals takes the win at 9.2/10 on its balanced dose and per-lot transparency, but Sports Research at 8.8/10 is an excellent one-a-day alternative — and the more convenient pill count.

How many softgels per serving?
