Value of Liquid Potassium Magnesium Citrate in Controlling Hypertension

Brief Overview


Liquid potassium-magnesium citrate (KMgCit) as a pharmaceutical formulation will lower blood
pressure among patients with pre- or Stage I hypertension on their customary diet.

Summary


In this protocol, the investigators want to explore whether KMgCit taken during a customary
dietary setting, might serve as a "surrogate" for the DASH diet to lower blood pressure.
This study has obvious biomedical importance. Lifestyle modifications are often recommended
for pre- or Stage I hypertension. The DASH diet is such a modification that has been shown
to be effective. However, this diet is costly and difficult to adhere to long-term. If
KMgCit were shown to be effective in lowering blood pressure, it would provide a safe and
convenient alternative to the DASH diet.
