Beetroot juice: the surprising sleep aid?
NCT ID NCT05864521
First seen Jun 27, 2026 · Last updated Sep 09, 2026 · Updated 2 times
Summary
This study looks at whether drinking beetroot juice, which is high in natural nitrate, before bed can change sleep patterns and how the brain controls blood flow. Researchers will give 60 healthy adults either active beetroot juice or a placebo and measure sleep stages, blood pressure, and nerve activity overnight. The goal is to understand the basic science, not to treat any disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

- Beetroot juice (inorganic nitrate)
- What this could lead to
- If it works, this could point toward a natural way to improve sleep quality and blood pressure regulation.
- What could go wrong
- This is a small, early-stage study in healthy people, so results may not apply to those with sleep or health issues. The effect may be minimal or absent.
