Is NOW third-party tested?

Last reviewed October 2026.

Not for the US bottle, as far as the public record shows. NOW has one product in the public IFOS certification database ↗: NOW Ultra 97% Omega-3 Fish Oil. Its listing gives now-global.tmall.hk (NOW's Tmall Global store for China) as the website, so it is a China-market product (checked 2026-10-08).

The IFOS product is NOW Ultra 97% Omega-3 Fish Oil: 1,230 mg omega-3 per serving of 2 mini softgels, in rTG form, with 18 lot reports listed. NOW's brand page in the same database lists no other product. The US NOW Ultra Omega-3 sold on Amazon and in US stores is a different product and has no IFOS listing. You can check NOW's brand page in Nutrasource's database ↗ yourself.

Why there is no buy link here

A link to the NOW bottle sold in the US would point to a product with no public IFOS report, so this page does not carry one. If you want a fish oil whose lot reports are public, the ranking covers every product whose IFOS report we have read. This page will change if the US product appears in the database.

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.

Protein powder from the same brand: is NOW Foods protein third-party tested?
