Blood pressure regulation is a key determinant of cardiovascular risk, and numerous studies have evaluated the relationship between omega-3 fatty acids and blood pressure control.
A dose-response meta-analysis examining omega-3 intake and blood pressure outcomes found that combined EPA and DHA intake was associated with measurable blood-pressure-lowering effects, with optimal intake levels estimated between 2 and 3 grams per day.

Vascular Mechanisms Supporting Blood Pressure Effects
Omega-3 fatty acids influence blood pressure regulation through:
-
Improved endothelial function
-
Reduced vascular resistance
-
Modulation of nitric oxide signaling
-
Anti-inflammatory vascular effects (PMC)
These physiological mechanisms contribute to the observed cardiovascular effects reported in clinical research.
Key Takeaway
Scientific meta-analysis data suggest that adequate intake of marine omega-3 fatty acids may contribute to modest improvements in blood pressure, particularly among individuals with elevated cardiovascular risk markers.
