My doctor told me to take an iron supplement, but I've heard it can be harmful. Is this true?

It depends on the type of iron you are taking and how much. Generally speaking, supplements that contain iron in its ferrous form (the kind found in most multivitamins) are considered safe for healthy adults. However, if you have a condition such as anemia or chronic kidney disease, you should consult with your doctor before taking any iron supplements.
