The Claim

Higher concentrations of EPA and DHA in omega-3 supplements do not lead to increased oxidation levels in commercial products.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Description
1 study reviewed
In plain English

Omega-3 supplements with more EPA and DHA do not oxidize more than those with less EPA and DHA.

See the scientific wording

Omega-3 supplements with higher concentrations of EPA and DHA did not show increased oxidation levels, indicating that fatty acid concentration alone does not predict oxidative degradation in commercial products.

Why this might work

Omega-3 supplements contain natural antioxidants that protect EPA and DHA from breaking down, so even when there is more of these fatty acids, they don't oxidize faster because the protective molecules are already present in the product.

  1. Study: Oxidation levels of North American over-the-counter n-3 (omega-3) supplements and the influence of supplement formulation and delivery form on evaluating oxidative safety

    Scientists checked if omega-3 supplements with more EPA and DHA spoiled faster, and found no difference — high-potency pills weren’t more oxidized than low-potency ones. So, more omega-3 doesn’t mean it goes bad quicker.
