Can a common supplement help dialysis patients?
NCT ID NCT07249229
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether taking oral L-carnitine (a natural supplement) three times a week for three months could reduce inflammation and improve nutrition in 50 adults with advanced kidney failure on chronic hemodialysis. Participants were randomly assigned to receive either L-carnitine or a placebo. Researchers measured changes in blood markers of inflammation and nutrition to see if the supplement offers any benefit.

- L-carnitine
- What this could lead to
- If it works, this could point toward a simple supplement to help manage inflammation and nutrition in dialysis patients.
- What could go wrong
- This is a small, early-phase trial (50 people) testing only short-term effects. Results may not lead to a proven treatment.
