An analysis of 8 clinical trials investigating the association between vitamin C supplementation and essential hypertension showed that vitamin C supplementation led to a significant reduction in blood pressure. For daily supplementation above 500 mg of vitamin C, these results were even statistically significant (P = 0.005). What is particularly remarkable about this research is the fact that these trials were conducted with patients suffering from so-called “essential hypertension”. This is a form of hypertension whose cause is unknown and therefore difficult to treat. Further details can be found in the study.
