This data has been known since 2000. It is not the fish-oil dose per se, but the reduction of the AA/EPA ratio in the blood that has the benefits. Ideally, the AA/EPA ratio should be about 1.5. For most Americans, it will take about 7.5 grams of EPA and DHA per day to reduce their AA/EPA ratio (currently the average is 18) to that level.
