What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether drinking beetroot juice before exercise can reduce inflammation and improve physical function in people with chronic kidney disease. Researchers will give 25 patients either beetroot juice or a placebo, then have them exercise. The goal is to see if this simple, natural approach can help manage complications of kidney disease.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
beetroot juice
What this could lead to
If it works, this could point toward a simple, non-drug way to help kidney disease patients feel better and move more easily.
What could go wrong
This is a very small, early-stage trial with only 25 people, so results may not apply widely. Beetroot juice is generally safe but may not provide meaningful benefits.
