Registry check · Flaxseed Oil
Does anyone independently verify Flaxseed Oil supplements?
1 of the 6 Flaxseed Oil products on this page is confirmed in USP Verified: Nature Made Flaxseed Oil 1000mg, Fish-Free Omega-3, 180 Softgels. Nature Made Flaxseed Oil 1000mg, Fish-Free Omega-3, 180 Softgels does not show the mark on the listing, so the table’s certification column, which repeats the listing, does not show it either. For the others, the listing may name a certification, but we did not find it in a public registry — that is not evidence against them, only an absence of independent confirmation.
Certification is not a dosing guarantee. Across the whole catalogue, certified products reach the clinically studied dose 57% of the time and uncertified ones 71% — a gap too small to mean anything (Fisher p = 0.185). Read the Flaxseed Oil dose column either way.
The 6 products on this page checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.
