Vitamin C lowers blood pressure to help prevent stroke and heart disease
The researchers found that taking an average of 500 milligrams of vitamin C daily, about five times the recommended daily requirement, reduced blood pressure by 3.84 millimeters of mercury in the short term, they can be sufficient to dramatically lower cardiovascular and stroke risk for the millions of adults diagnosed with mild hypertension.
Vitamin C acts as a diuretic, helping the kidneys to remove more sodium and water from the body, which helps to relax the blood vessel walls, thereby lowering blood pressure.
Vitamin C is also known to improve essential endothelial function of delicate artery walls, effectively restoring elasticity and resolving micro-cracks in the vessels that lead to arterial plaque formation.
Dr. Miller concluded "Although our review found only a moderate impact on blood pressure, if the entire U.S. population lowered blood pressure by 3 milliliters of mercury, there would be a lot fewer strokes."
Most nutrition experts recommend up to three grams of vitamin C supplementation per day for optimal protection from hypertension, cardiovascular disease and stroke.
