Is Solgar third-party tested?

Last reviewed July 2026.

Not that we can verify. Solgar's omega-3 line is a repeat iHerb bestseller, but as of the last review we could not find a public IFOS, NSF, or USP certificate for it, and Solgar has described its testing data as proprietary rather than published.

Why that matters

"Third-party tested" only means something if you can read the test. When a brand doesn't publish a certificate, you're trusting the label's claim on potency, freshness, and purity with no independent check. That's not proof of a bad product — but it is a real gap next to brands whose IFOS or NSF certificates are one click away.

If you want products where the numbers are public and comparable, our ranking only includes fish oils with a verifiable third-party certificate, sorted by cost per gram of lab-measured EPA+DHA.

If Solgar begins publishing third-party certificates, we'll update this page — the source always wins.

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.
