Calcium supplementation for hypertensive disorders and related problems

Calcium supplementation offers some benefit in reducing blood pressure and the risk of developing pre-eclampsia for women at high risk of gestational hypertension living in communities with low dietary calcium intake. Optimum dosage requires further investigation.
RHL Commentary by Andres de Francisco

EVIDENCE SUMMARY

Calcium supplementation (>1 g per day) was found to be modestly beneficial overall in reducing blood pressure and pre-eclampsia. These effects, however, were greatest in women who were at high risk of gestational hypertension and who also had low dietary calcium intake. In addition, a reduction in preterm delivery was found in women at a high risk of hypertension.

The methodology employed in the review was sound, with all relevant studies having been included.
