Summary
This study looked at why many older adults (over 70) have anemia even when doctors can't find a reason. Researchers measured how long red blood cells live in younger and older adults by marking them with a vitamin called Biotin. The goal was to understand if faster red blood cell breakdown causes unexplained anemia. No treatments were tested.
