Wang L et al.
Hypertension. 2008;51:1073-9.
After examining the diets of 28,886 US women aged ≥45 years over a 10-year follow-up period, these researchers found that those women who consumed more low-fat milk and had higher intakes of calcium and vitamin D from foods, and not supplements, tended to have a lower risk for developing hypertension or high blood pressure.


Calcium plus linoleic acid therapy for pregnancy-induced hypertension.
Herrera JA et al.
Int J Gynaecol Obstet. 2005 Dec;91(3):221-7.
Dietary supplementation of daily elemental calcium (600 mg) plus conjugated linoleic acid (450 mg) from week 18 to 22 of pregnancy until delivery effectively reduced the incidence of vascular endothelial dysfunction in pregnant women at high risk of developing pregnancy-induced hypertension.

Mu JJ et al.
J Hum Hypertens. 2005;19:479-83.
In children with salt sensitivity, calcium and potassium supplementation promoted urinary sodium excretion and a lower increase in blood pressure by 4.3/4.8 mm Hg than that in the placebo group.
