Health Benefits Of Omega-3 Fatty Acid (Fish Oil) Supplementation Category: Diet & Weight Loss by - February 23, 2014 | Views: 77616 | Likes: 1 | Comment: 0  

High Blood Pressure

Many studies report that omega-3 fatty acids may help reduce blood pressure (BP) slightly, while others report no change at all. Effects may depend closely on the dose used, and may be greater in people who have high blood pressure.

In an analysis of 36 trials, fish oil supplementation (3.7 g/day, duration 8 weeks) among adults older than age 45 lowered systolic blood pressure (BP) by 3.5 mmHg and diastolic BP by 2.4 mmHg. In younger healthy adults (younger than age 45), the BP-lowering effects were less pronounced.

Secondary Prevention of Heart Disease

Fish oil has been studied for use in protecting people with previous heart problems from further complications such as heart attack or sudden death. Many studies report the reduction in risk of nonfatal and fatal heart attack, sudden death, and death in people with a history of a heart attack when omega-3 fatty acids are used for at least 3 months.

There is also evidence of a lower risk of heart failure with omega-3 fatty acid intake. In one large trial of 7046 patients with chronic heart failure, fewer patients treated with 1 gram daily omega-3 FA died (27% vs. 29% in placebo), and there were significant improvements in left ventricular ejection fraction.
