Fascinating. You can have an iron deficiency, even if your hemoglobin levels are normal, because iron does more than just carry oxygen in red blood cells: It's a cofactor for many enzymes. I'm curious if there's a third variable at play here; something preventing the iron from being accessible (since our bodies normally break down ferritin to access the iron), especially when hemoglobin levels are otherwise normal. I suspect there might be.
