According to a recent research review published in the Journal of the American Heart Association, roughly “3 grams daily of omega-3 fatty acids, consumed in foods or supplements, appears to be the optimal daily dose to help lower blood pressure.” Omega-3 fatty acids can be found in fatty fish like salmon, tuna, or sardines. About “4-5 ounces of Atlantic salmon provide 3 grams of omega-3 fatty acids.” You can also take a high quality supplement to get your daily 3 gram dose. While the exact optimal dose is not known, “a review of dozens of studies suggests that the optimal amount of omega-3 fatty acids to consume to lower blood pressure is likely about 3 grams daily.”
