🐟 Why TOTOX Value In Fish Oil Is Crucial
Most fish oil brands tell you how much EPA and DHA they contain.
Few tell you how fresh those omega-3s actually are. That's where TOTOX comes in.
TOTOX is a measure of oxidation in an oil:
TOTOX = (2 × Peroxide Value) + Anisidine Value
In simple terms, it tells you how fresh and stable an oil is by measuring both early-stage and advanced oxidation.
Why does that matter?
Because oxidation damages omega-3s.
As fish oil oxidizes:
❌ EPA and DHA begin to break down
❌ Unpleasant flavors and odors develop
❌ The oil becomes less biologically active
When oxidation is kept very low:
✅ EPA and DHA remain intact
✅ The oil tastes cleaner and fresher
✅ The body can utilize omega-3s more effectively
✅ The nutritional value is preserved
Many experts consider a TOTOX below 10 to indicate a high-quality fish oil.
Omega Cure consistently tests at a TOTOX of approximately 3 — an exceptionally low level that reflects careful sourcing, handling, and bottling.
Freshness isn't just a quality metric.
It's what helps preserve the omega-3s you're taking the product for in the first place.
Because the best fish oil isn't simply the one with the most EPA and DHA on the label.
It's the one that keeps those omega-3s fresh enough to deliver their intended benefits.
