Value of Liquid Potassium Magnesium Citrate in Controlling Hypertension

Summary

In the DASH (Dietary Approaches to Stop Hypertension) trials, a diet rich in fruits, vegetables, nuts and dairy products, and limited in fat content, was shown to be useful in controlling hypertension. Key components of such a diet are potassium, magnesium and alkali, each of which has been implicated in lowering blood pressure. Whether a liquid formulation of potassium-magnesium citrate will result in equivalent BP effect as the DASH diet is unknown.
