The Dietary Guidelines for Americans recommend that people consume 8 ounces (approximately two servings) of fish per week, which is about 250 to 500 milligrams of marine omega-3s EPA plus DHA.
Unfortunately, evidence suggests that 90% of Americans6 are failing to meet this baseline benchmark of 500 milligrams of marine omega-3s per week.
While this dosage may be enough to provide foundational heart-health benefits, the American Heart Association7 suggests the general population up their intake to at least 1,000 milligrams (1 gram) of combined EPA and DHA per day (from fatty fish and/or high-potency omega-3 supplements) for more comprehensive cardiovascular support.*
The recent Frontiers review revisits the clinical recommendation, analyzing the dosage required to exceed the recommended omega-3 index level associated with cardiovascular benefits (i.e., above or equal to 8%). To achieve this goal, researchers determined the following suggestions for omega-3 supplementation:
