NCT07258004 · NOT YET RECRUITING
An Investigation Into the Feasibility of Beetroot Juice Supplementation in People Living With Alzheimer's Disease.
This small study is testing whether people with mild or moderate Alzheimer's disease can realistically drink beetroot juice twice a day for one week. Researchers will track side effects, how acceptable it is, and any changes in health measures. It is a feasibility study with no phase, so it checks practicality, not whether it works.

- Mild or Moderate Alzheimer's disease
- Participants must be able to speak, read, and understand English to participate in this study.
- To support adherence, participants are asked to have a carer, partner, friend, or family member available to assist with reminders to take the shots twice daily.
