Fish Oil (2012) & Hypertension

Learn more about hypertension.

The researchers wanted to evaluate the veracity of the belief that fish oil is helpful in reducing blood pressure.

They evaluated 17 studies involving more than 1500 hypertensive and normotensive subjects. They found, in 8 studies, a statistically significant reduction in systolic and diastolic blood pressure in hypertensive patients. They found, in 9 studies, a non-significant reduction in normal blood pressure subjects.

Their conclusion was that in high blood pressure patients there is a small but statistically significant benefit, but that it should not be recommended as an alternative to blood pressure lowering medication.
