Is NOW third-party tested?

Last reviewed July 2026.

Yes — and you can read the listing yourself. NOW appears in the public IFOS certification database ↗ — verified 2026-07 — covering Ultra 97% Omega-3 Fish Oil, with per-lot reports running through 2028 expiry dates. IFOS is the strictest kind of public record in this category: per-lot consumer reports with measured EPA/DHA, oxidation and contaminant results, not a one-time badge.

NOW's flagship concentrate is actively IFOS-listed — the public product page carries 15+ per-lot reports with recent lot numbers, which is the strongest kind of paper trail: not one golden batch, an ongoing record.

Why it isn't in our ranking (yet)

Our main table ranks products on cost per gram of lab-measured EPA+DHA — which means we only add a product once we've read its actual batch report and extracted the measured numbers. NOW's reports are in the database and this page will graduate into the ranking when we've pulled a current lot. The certification answer, though, doesn't need to wait — it's yes, and the listing is linked above.

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.

This page summarizes published third-party testing data and makes no health, benefit, or treatment claims. A certificate describes one tested batch, not a permanent grade.
