Dialysis patients may benefit from common supplements, study finds
NCT ID NCT07303088
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether taking L-carnitine or Coenzyme Q10 supplements could lower oxidative stress (a type of cell damage) in adults with end-stage kidney disease who are on regular hemodialysis. Fifty-two participants took one of the supplements or a placebo for 12 weeks, followed by a 12-week washout period. Researchers measured blood markers of oxidative stress before, after treatment, and after the washout to see if the supplements helped.
