Low Blood Pressure
It is commonly known that fish oil can lower blood pressure. When compared to a placebo, consuming 3 grams of omega-3 fatty acids daily drastically decreased both systolic and diastolic blood pressure in one research involving 90 patients.
Similar to the above, a review of 31 research found that consuming fish oil can significantly lower blood pressure, particularly in people with high cholesterol or high blood pressure. While these effects can undoubtedly be beneficial for people with high blood pressure, people with low blood pressure may have big problems. If you're being treated for high blood pressure, it's crucial to discuss supplements with your doctor because fish oil may also interact with blood pressure-lowering medications.
