Three different supplements will be used in the study (fruits and vegetable powders, whey
protein and calcium) for patients with hypertension. The null hypothesis was that the
supplements had no effects on participants' blood pressure.
Hypertensive participants will be randomly assigned into three groups. The first group of
participants will take the fruits and vegetable powders mixed with water. The second group
takes whey protein and the third group takes calcium pills. Blood pressure and heart rate
variability will be measured every two weeks for three months.
