First seen Nov 01, 2025 · Last updated May 15, 2026 · Updated 34 times
Summary
This study looked at 135 adults who had heart bypass surgery to see if vitamin D levels before surgery affect how quickly their hemoglobin (a part of red blood cells) recovers afterward. Researchers also measured a protein called hepcidin, which controls iron in the body. The goal was to better understand why many heart surgery patients have low red blood cell counts and how vitamin D might help.
