3 g of omega-3 fatty acids/day Helps in lowering blood pressure

According to a research review published in the Journal of the American Heart Association, about 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 are typically found in fatty fish, such as salmon, tuna, sardines, trout, herring and oysters. Some people also take combined docosahexaenoic acid and eicosapentaenoic acid in supplements. While some studies suggest that consumption of omega-3 fatty acids may lower blood pressure, the optimal dosage needed to lower blood pressure has not been clear. The National Institutes of Health has established an adequate intake of omega-3 fatty acids for healthy people at 1.1- 1.6 grams daily, depending on age and sex.

Researchers analyzed the results of 71 clinical trials and studies examined the relationship between blood pressure and the omega-3 fatty acids in people aged 18 and older with or without high blood pressure or cholesterol disorders. There were nearly 5,000 participants combined, ranging in age from 22 to 86 years. Participants took dietary and/or prescription supplement sources of fatty acids for an average of 10 weeks.
