Is Nordic Naturals third-party tested?

Last reviewed October 2026.

Yes for its Sport omega-3s, through NSF; not through IFOS. NSF Certified for Sport's product list ↗ (checked 2026-10) includes Nordic Naturals Ultimate Omega 2X Sport and Ultimate Omega-D3 Sport (US listings, each with its lot numbers), not the regular Ultimate Omega. NSF Certified for Sport is an independent program that tests products for label accuracy and banned substances and lists the certified lot numbers.

Nordic Naturals is the biggest search-volume brand in fish oil, so the details matter. Its entries in Nutrasource's database (the home of IFOS) carry IGEN non-GMO certification, not IFOS lot reports with measured EPA and DHA: none of its 162 listed products showed an IFOS lot when we read them. Nordic itself says its products are third-party tested and that a Certificate of Analysis is available for any product; that is the maker's own paperwork, not a public registry. You can check the Nutrasource listing ↗ yourself.

The certified SKU on Amazon is Nordic Naturals Ultimate Omega-D3 Sport, 60 softgels: NSF United States listings 1204292 ↗ and 1400694 ↗ (read 2026-10-08), 30 servings of 2 softgels. On 2026-10-08 the listing was sold by Nordic Naturals.

Why it isn't in our ranking

Our main table ranks products on cost per gram of lab-measured EPA+DHA, so a product enters only once a public batch report gives the measured numbers. NSF's listing names the certified lots but does not publish measured EPA and DHA, and no current IFOS report for Nordic Naturals was in Nutrasource's database when we checked. This page will change if one appears.

If you want the products where the actual numbers are public, the ranking covers every fish oil whose batch report we've read, sorted by cost per gram of measured EPA+DHA. Background: what "third-party tested" really means.

Nordic Naturals vegan omega-3: is it third-party tested?

Nordic Naturals Algae Omega and Algae DHA have no NSF Certified for Sport or IFOS entry. Nutrasource lists both as IGEN certified, which is a non-GMO test, not a purity test.
