Drink water to forward blood pressure research

If you have raised blood pressure, take part to support Oxford Brookes' research and earn Amazon vouchers


The Oxford Brookes Centre for Nutrition and Health is recruiting for a study investigating the effects of potassium-rich water on blood pressure.  

The aim of this study is find out whether drinking 1 Litre per day of water rich in potassium will reduce blood pressure in mild to moderately hypertensive adults and to assess whether this intervention has the potential to reduce blood pressure in the general population.

Who can take part? 
The study is open to men and women aged between 20 to 64 with mild to moderately raised blood pressure who are not taking medication. 

Mild to moderately raised blood pressure includes readings of 130-139mmHg for the top number (systolic) and 80-89mmHg for the bottom number (diastolic).

This is the first time Oxford Brookes Centre for Nutrition and Health has done a study where all visits are virtual and they’re able to send all necessary equipment to participants, meaning they are able to recruit people nationwide. 

What’s involved? 

If you take part, you will be asked to: 
•    drink the test product (potassium-rich water) daily for 4 weeks
•    attend 3 virtual sessions
•    take your own blood pressure at home
•    provide urine samples.
