Buy at Nature Made (direct)why this one

Partly: 1 of the 7 Thorne fish oil packages 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 holds one Super EPA listing, recorded against the 90-count bottle sold with the mark on the strength of the label the listing files, which prints one softgel a serving. The standard Super EPA bottles print one gelcap a serving, and no listing names them at either count.

What the listings say

The records here rest on 1 Certified for Sport listing (1237707). 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.

6 products here have no NSF Certified for Sport listing. That is an absence in a database, not a failed test: these programs certify what a company submits to them, and NSF Certified for Sport is one program among several. All 6 of their labels print NSF's Contents Certified mark, which belongs to a different NSF program, one this page does not read.

What each product page shows

Listing 1237707 prints Package Size 90 and Serving Size 1 Gelcap, and its filed label image prints the panel of this bottle (Serving Size: One Softgel, Other Ingredients: Softgel (Gelatin (bovine)...)), which is the wording of the bottle Thorne sells with the Certified for Sport mark, SP608, and not of the standard SP608NC bottle (One Gelcap). Read as naming this 90-count package on that label evidence; the typed word Gelcap is taken as NSF's data entry.

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.

No pick yet. These came closest

A pick has to be independently certified, at the exact package sold where the certifier names packages, with no recall or failed test, a price its retailer let us read recently, and no more than a year’s supply at the label’s serving. Where the retailer publishes no delivery rate, the pick is priced before delivery and says so. Nothing we track here clears all of those yet. Each of these misses at least one bar, and says which (the first clears the certification bar):

Sports Research Omega-3 Fish Oil Liquid, Lemon (8 oz) $0.446 per 1,000mg, delivered, its price is 10 days old and we cannot refresh it automatically. Free delivery starts at $50.00, so this order is $5.05 short.
