The truth is more nuanced: supplements clearly lower triglycerides, but evidence that they prevent heart attacks in the general population is mixed. Here are 7 facts based on the major trials.<\/p>\n<p>For the broader overview of omega-3 fats and food sources, see our <a href=\"https:\/\/nostylelike.net\/en\/jointace-omega-3-guide\/\">omega-3 guide<\/a>.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"1_Omega-3_for_heart_health_lowers_triglycerides\"><\/span>1. Omega-3 for heart health lowers triglycerides<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>This is the clearest proven effect. Doses of 2 to 4 g a day of EPA plus DHA can lower triglycerides by roughly 20 to 30 percent in people with high levels. When people use omega-3 for heart health this way, these are high doses taken under medical supervision, not the amount in a single capsule.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"2_Prevention_in_the_general_population_mixed_results\"><\/span>2. Prevention in the general population: mixed results<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In the VITAL trial, more than 25,000 adults took 1 g of omega-3 a day, and major cardiovascular events were not significantly reduced. In ASCEND, among people with diabetes, serious vascular events were not reduced either. So omega-3 for heart health is not a substitute for treatment or for controlling blood pressure and cholesterol.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"3_Prescription_omega-3_is_a_different_product\"><\/span>3. Prescription omega-3 is a different product<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The REDUCE-IT trial showed fewer cardiovascular events with icosapent ethyl at 4 g a day, a purified prescription form of EPA, in high-risk patients on statins with raised triglycerides. This does not mean ordinary fish oil supplements give the same result. To learn what each fat does, read <a href=\"https:\/\/nostylelike.net\/en\/epa-vs-dha\/\">EPA vs DHA<\/a>.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"4_Atrial_fibrillation_at_higher_doses\"><\/span>4. Atrial fibrillation at higher doses<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Pooled analyses of several trials found a small increase in the risk of atrial fibrillation with omega-3 supplements, more noticeable at doses above 1 g a day and up to 4 g. Anyone with a heart rhythm problem considering omega-3 for heart health should talk to their doctor before starting, and seek care promptly for palpitations or dizziness.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"5_Blood_thinners_and_surgery\"><\/span>5. Blood thinners and surgery<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Omega-3 may increase bleeding tendency when combined with warfarin or antiplatelet drugs such as aspirin and clopidogrel. Tell your doctor about the supplement and stop it before surgery as instructed.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"6_How_much_omega-3_for_heart_health_do_our_products_give\"><\/span>6.

The same applies before surgery or with liver disease. A healthy person who eats fish regularly usually does not need a supplement, and is better served by a balanced diet, physical activity and regular checks of blood pressure and blood fats.
