Large Daily Dose Of Vitamin C Reduces Blood Pressure, But Not As Much As Medications

U.S. researchers who analyzed data from 29 published clinical studies find that taking an average of 500 mg of vitamin C every day reduces blood pressure by 3.84 mm of mercury in the short term. That amount of vitamin C – five times the recommended daily dosage and equivalent to six cups of orange juice  – reduces the blood pressure of people diagnosed with hypertension by 5 mm of mercury. By contrast, patients who take blood pressure medication such as ACE inhibitors or diuretics can expect a 10 mm of mercury drop in blood pressure.
