Summary

This study tests whether taking L-carnitine, a natural substance that helps turn fat into energy, can improve symptoms and quality of life in people with heart failure and kidney problems. About 20 adults will take the supplement for a short time while researchers monitor side effects, adherence, and symptom changes. The goal is to see if this approach is safe and worth studying further.
