Intervention
What is the effect of zinc supplementation on homocysteine levels in adults with CKD 1-5D and post-transplant?
- Conclusion
  There was no effect of 50 mg per day zinc supplementation for six weeks on homocysteine levels, but results were limited.
- Grade: II
  - Grade I means there is Good/Strong evidence supporting the statement;
  - Grade II is Fair;
  - Grade III is Limited/Weak;
