NCT ID: NCT05412654 Phase: NA Status: COMPLETED Enrollment: 40 Completion: 2023-12-01
Conditions
Prehypertension
Interventions
High potassium water, Control low potassium water
Summary
The aim of this study is to conduct a definitive trial to assess the efficacy of consuming 1L/day of water rich in potassium to reduce blood pressure in mild to moderately hypertensive adults. The objective is to assess the potential effect of the intervention on reducing systolic blood pressure. This study will comprise of a 4 week, double-blind, parallel randomised controlled trial. Participants will be adults with systolic blood pressure measurements of 130mmHg or greater. The intervention comprises advice to consume bottled water rich in potassium. The comparator will be regular bottled mineral water.This study will recruit 40 people with elevated systolic blood pressure (≥130mmHg) who are not regularly taking antihypertensive medication.
Primary Outcome
Seated home measured systolic blood pressure mm/Hg
