Could tweaking dialysis fluid improve mineral balance in kidney patients?
NCT ID NCT07663279
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding extra bicarbonate and magnesium to the fluid used during dialysis can improve how well the body handles minerals like calcium and phosphate. It involves adults with end-stage kidney disease who have been on dialysis for at least three months. Each participant will try four different dialysis fluid recipes to see which one works best for mineral balance.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bicarbonate and magnesium in dialysis fluid
- What this could lead to
- If it works, this could point toward a simple way to improve mineral balance and reduce heart-related risks in dialysis patients.
- What could go wrong
- This is a small, early-stage study testing a short-term change in dialysis fluid. It may not show a clear benefit or lead to long-term improvements.
