High blood pressure (hypertension) is a leading cause of cardiovascular disease, with more than 1 billion people worldwide suffering from the condition.   Stephen P Juraschek, from Johns Hopkins School of Medicine (Maryland, USA), and colleagues completed a meta-analysis of 29 clinical trials, in which the median dose of vitamin C supplementation was 500 mg per day for a median duration of eight weeks. Across study subjects, the researchers found that vitamin C supplementation reduced systolic blood pressure by 3.84 mm Hg and diastolic blood pressure by 1.48 mm Hg. Further, when the team looked at hypertensive patients only, vitamin C supplementation exerted and even greater benefit – reducing systolic pressure by 4.85 mm Hg and diastolic pressure by 1.67 mm Hg. cap the study authors conclude that: "In short-term trials, vitamin C supplementation reduced [systolic blood pressure] and [diastolic blood pressure].
