Beetroot juice: a surprising new hope for Alzheimer's?
NCT ID NCT07258004
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study explores whether drinking beetroot juice twice a day is practical and acceptable for people with mild-to-moderate Alzheimer's disease. Thirty participants will take the juice for one week, with help from a caregiver, to see if they can stick with it and if it causes any side effects. Researchers will also check for changes in oral bacteria and other health measures. The goal is to see if a larger trial on beetroot juice for Alzheimer's is worth doing.
