Scientists found that adding a specific amount of a fish oil component called EPA to blood proteins in a test tube cut down their damage from rust-like oxidation by more than half in just two hours.

Assessment Explanation
The claim describes a precise, controlled in vitro experiment with a specific concentration, time point, and quantitative outcome (61% reduction). Such claims are standard in biochemical assays where conditions are tightly regulated and measurements are direct. The use of 'attenuated' and the exact percentage are appropriate for this context, as in vitro oxidation assays are designed to yield reproducible, quantitative results. No overstatement is present because the claim is limited to the experimental conditions and does not generalize to humans or in vivo effects.
More Accurate Statement
“In an in vitro experiment, 50 µM eicosapentaenoic acid (EPA) reduced the oxidation of lipoprotein(a) (Lp(a)) by 61% after 2 hours of copper-induced oxidation compared to vehicle-treated control samples.”

Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies
Supporting (1)
Scientists gave Lp(a) a fatty acid called EPA and found it stopped the Lp(a) from getting damaged by copper, just like the claim said—EPA cut the damage by 61%.
