Carlson The Very Finest Fish Oil: what the IFOS report shows

Last reviewed July 2026.

This is what the paperwork behind The Very Finest Fish Oil, Natural Lemon (liquid), 500 ml actually says. The tested lot (60049101) carries an IFOS certificate — the public, per-lot consumer report, and the numbers below come from that report, not from the label.

The tested numbers

• Measured EPA: 800 mg per teaspoon (5 ml) serving
• Measured DHA: 500 mg per teaspoon (5 ml) serving
• Combined EPA+DHA: 1300 mg per teaspoon (5 ml) serving — 100% of the 1300 mg label claim (over-delivers)
• TOTOX (freshness): 9.34 — acceptable (what TOTOX means)
• Heavy metals: passed all CRN/GOED limits in the tested lot
• Form: TG (triglyceride — the form found in fish)
• IFOS rating: 5 out of 5 stars

What a gram of it costs

At $56.66 for 100 servings (current price on iHerb ↗), this works out to $0.44 per gram of measured EPA+DHA — #7 of 8 tested products we track. The sticker price and the per-gram price rank very differently; the full ranking shows exactly what beats it.
