Oral calcium supplementation and blood pressure: an overview of randomized controlled trials.
Over the past few years , several trials on the effect of oral calcium supplementation on blood pressure have been undertaken both in normal subjects and in patients with high blood pressure . Of these , 15 r and omized , controlled studies were review ed : 10 included patients with high blood pressure , three studied normal subjects , and two used a low-calcium diet for comparison . The 15 studies review ed investigated a total of nearly 400 peoples . No significant evidence for a supine blood pressure-lowering effect of oral calcium supplementation was found in the trials as a whole or in those trials carried out in hypertensives only . However , a small effect on st and ing blood pressure was detected . Our study indicates that the overall effect of oral calcium on blood pressure , if any , is very small and confined to st and ing blood pressure , it is , therefore , inappropriate to recommend oral calcium supplementation for the treatment of essential hypertension
