Can Fish Oil Lower Blood Pressure?
Yes It Can
The effect is not huge, but it's significant. Why it works is still being debated, but it seems that the effect is primarily due to its anti-inflammatory activity.
The Omega-3 fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are the major components in fish oil responsible for this effect. These omega-3 fatty acids make hormones that reduce inflammation
Most studies on fish oil supplementation suggest that higher amounts should be taken to lower blood pressure. Extreme amounts may also increase the risk of bleeding, however, so you should consult your doctor before taking fish oil - or indeed any supplements.
You should also keep a record or tellbeth about the supplements you're taking so that you and your doctor can review their effects.
