Nordic Naturals and Carlson's have the best third-party lab test results.

I take the ones from nordic, a friend recommended it to me and it's been good for me so far, so I haven't tried any other brands yet

Nordic Naturals is high quality, so your dosing is good if well-tolerated.

Look for an IFOS certified product or Nordic Naturals.

You want triglyceride form (rTG), for better absorption not the free fatty acid form (EE) - try Sports Research, Nordic Naturals, Viva Naturals, Carlson.

What are you talking about? Sports Research is IFOS tested.
positive · u/F****2 · r/Supplements · comment · Dec 21, 2025 · open on Reddit ↗
For example, look up Sports Research, Carlson, or Viva Naturals (all sell IFOS cert oils on Amazon I think) and compare the TOTOX value, it's interesting to see.
