Do you have questions about
your blood pressure?

Help us find out if dietary potassium supplements improve blood pressure.

A research program of Tulane University Translational Science Institute and the National Institutes of Health

What is the PITCH study?

The PITCH Study is an important research study that will help us learn whether higher levels of potassium in the diet can help lower blood pressure. The goal is to create safe and effective options for protecting heart health.

If you qualify and agree to participate in the PITCH Study, you will be assigned to 1 of 3 groups taking potassium supplements or 1 group receiving a placebo.

You will have a greater chance of receiving a potassium supplement than placebo.

Dietary potassium supplements could help lower blood pressure – without needing to take medication or make big changes to your diet.

Did you know

Nearly half of adults in the United States (47%, or 116 million) have hypertension, defined as a systolic blood pressure greater than 130 mm Hg or a diastolic blood pressure greater than 80 mm Hg, or are taking medication for hypertension. In 2020, more than 670,000 deaths in the United States had hypertension as a primary or contributing cause. Having high blood pressure puts you at risk for heart disease and stroke, which are the leading causes of death in the United States.

What would I need to do?

All participants will complete five clinic visits over 12-weeks. Once in the study, you will receive gift cards for your participation, and a free personalized dietary counseling session with a Registered Dietitian at the end of the study.

Visits are held at our clinic at 1440 Canal Street in New Orleans and there is free parking.
