Vitamin C Lowers Blood Pressure

Am J Clin Nutr May 2012 vol. 95 no. 5 1079-1088


Background: In observational studies, increased vitamin C intake, vitamin C supplementation, and higher blood concentrations of vitamin C are associated with lower blood pressure (BP). However, evidence for blood pressure-lowering effects of vitamin C in clinical trials is inconsistent.

Results: Twenty-nine trials met eligibility criteria for the primary analysis. The median dose was 500 mg/d, the median duration was 8 wk.......

Conclusions: In short-term trials, vitamin C supplementation reduced SBP and DBP. Long-term trials on the effects of vitamin C supplementation on BP and clinical events are needed.

Dr. E comments:

Lead study author, Dr. Peter R. Miller commented "Our research suggests a modest blood pressure lowering effect with vitamin C supplementation," noting that vitamin C taken at higher doses than suggested by the recommended daily requirement (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. Among those diagnosed with hypertension, the drop was nearly 5 millimeters of mercury. While these results may not sound dramatic, they can be sufficient to dramatically lower cardiovascular and stroke risk for the millions of adults diagnosed with mild hypertension.

The team noted that the blood pressure lowering effect of vitamin C supplementation was likely due to the nutrient's biological and physiological effects. Vitamin C acts as a diuretic, causing the kidneys to remove more sodium and water from the body, which helps to relax the blood vessel walls, thereby lowering blood pressure.

I take and recommend at least 2 grams a day of Vitamin C. Our chewable ProC has 750mg of Vitamin C and Probiotics. Probiotics along with its other benefits has also been shown to lower blood pressure.
