Study summary

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.

Read the detailed description

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.
