DEAR DOCTOR K: I have iron deficiency anemia. What could have caused it? Also, my doctor wants me to take a daily 325 mg iron sulfate supplement. Is that dangerous? The recommended daily dose of iron is much lower.
DEAR READER: Most iron in the body is stored in red blood cells. If you don't have enough iron, it can lead to a low red blood cell count. Doctors call this iron-deficiency anemia, and it's more common in women.
