Is Nordic Naturals third-party tested?
Partly: 1 of the 6 we track, not all of them. NSF lists a specific package against each certificate, and a certificate is what NSF actually stands behind, so a package the listing does not name is treated as unconfirmed rather than certified. Every row below was read against NSF's own listing, and the listing ID is shown.
NSF Certified for Sport holds one listing here, for Ultimate Omega-D3 Sport, and it names the 60-softgel bottle. The five Ultimate Omega bottles are a different product line and no NSF listing names them. Nordic Naturals also appears in Nutrasource’s certified-products directory, the one that publishes IFOS results, with 172 entries; the Ultimate Omega entry there carries an IGEN non-GMO pass and no IFOS testing result, so it is recorded as not listed under IFOS. The brand publishes its own certificates of analysis for every lot, which this site does not count as independent because the brand commissions them.

What the listings say
Nordic Naturals holds 1 Certified for Sport listing covering the products in this table (1204292). NSF records some brands under more than one spelling, so a search on the brand name alone can miss a listing; ours are found from a full read of the directory, then opened one by one.
5 products here have no NSF listing at all. That is an absence in a database, not a failed test: most supplements have never been independently tested, and NSF Certified for Sport is one program among several.
What each product page shows
Where to buy: the fish oil shortlist
The pick is the cheapest certified product, at the exact package sold where the certifier names packages, with no adverse finding on record, a price its retailer let us read recently, and no more than a year’s supply at the label’s serving; per delivered dose where the retailer publishes a delivery rate. Where none does, it is the cheapest such product before delivery, and it says how far the order is from free delivery. It is the same pick the category page shows. Any answer shown beside it is the cheapest under a different rule and says so on its own line; answers that cost more than the pick fold under one line until you ask for them.
How these lines are chosen
Among 49 products and 49 retailer listings we track; Amazon and Walmart are not included. A month is thirty doses of the size in the heading, priced the same way as the per-dose figure beside it. “Delivery known” ranks only products whose retailer publishes a delivery rate; a cheaper product with an unpublished rate is on its own line, or in the full list below.

What this rests on: prices we last recorded at the retailer named on each product page, which go stale, and each page says when it was checked; the products we track, not every product sold, and Amazon and Walmart are not among the stores; listings and labels read at the source, each linked from the page.
