Effect on blood pressure of potassium, calcium, and magnesium in women with low habitual intake.

What Was Tested

This randomized controlled trial looks at Magnesium and Calcium in the context of low blood pressure and orthostatic hypotension.

The researchers tested the hypothesis that normotensive persons who have low habitual intake of these minerals would be particularly responsive to supplementation.

Who Took Part

By PubMed's age tags, the people studied were adults, women only.

How the Study Was Run

The researchers set it up as a randomized, double-blind and placebo-controlled study.

Because people in this Magnesium study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

As a double-blind Magnesium study, the assignments were hidden from both participants and investigators until the end.

The comparison arm used a placebo, so changes seen with Magnesium could be set against what happens without it.

What Was Measured

The researchers tested the hypothesis that normotensive persons who have low habitual intake of these minerals would be particularly responsive to supplementation.
