Phase 2 — Testing in a bigger group (up to a few hundred people) to see if the treatment actually works and is still safe.
This trial is testing whether and D supplementation given before an allogeneic stem cell transplant can help prevent serious complications. Researchers believe these vitamins may help protect the healthy bacteria in your gut, which plays a surprising role in transplant recovery and reducing harmful side effects.
Stem cell transplants save lives but can damage the gut bacteria that normally protect us from infection and inflammation. This study aims to see if boosting these protective bacteria with vitamin supplementation before transplant can reduce complications like graft-versus-host disease and severe infections.

If you join this study, you will receive either the and D supplements or standard care. Those receiving the supplements will take them for one week (days 14 to 8 before your transplant), then proceed with your regular transplant procedure. You'll be followed closely during and after your transplant to monitor for complications and track your recovery.
