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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| High potassium water | Experimental | All participants will be provided with bottled water for the duration of the 4 week intervention to consume 1L/day. The intervention group will receive high potassium water. Participants will be instructed to consume 1 bottle (500 mL) within 2 hours after waking up and 1 bottle (500 mL) within 2 hours before going to bed (total 1L/day). Participants will continue with the same diet and exercise patterns in their daily life similar to before participating in the study, for the whole length of the intervention. |

| Low potassium control water | Placebo Comparator | All participants will be provided with bottled water for the duration of the 4 week intervention to consume 1L/day. The control group will receive regular bottled mineral water. Participants will be instructed to consume 1 bottle (500 mL) within 2 hours after waking up and 1 bottle (500 mL) within 2 hours before going to bed (total 1L/day). Participants will continue with the same diet and exercise patterns in their daily life similar to before participating in the study, for the whole length of the intervention. |

| Qualitative semi-structured, part open ended survey of acceptability of trial and reported barriers | This survey will be designed by the researchers understand the participant experience of the intervention, in order to optimise any future study expansion. This will include things that worked well and those that did not work as well, during the trial (consumption of the water, convenience, appropriateness of outcome measures, burden on daily activities and lifestyle, etc.) | This survey will be administered on the final visit at week 4 of the trial. |
