In an evaluation of 11 double-blind, placebo-controlled trials, the correlation between dietary supplementation with the natural amino acid arginine and changes in blood pressure was investigated. The analysis of these trials showed that arginine supplementation led to a highly significant reduction in both systolic and diastolic blood pressure. One particularly remarkable aspect of this study was that it was published in the American Heart Journal, an official body of the American Heart Association (AHA), thus gaining wide recognition, especially among cardiologists. More details can be found in the study.
