Yes: You can if your doctor prescribes it. If you have a condition requiring iron supplementation then by all means do so under the guidance of your physician.

NO!: I strongly advise everyone take a quality multivitamin as the vast majority of americans don't get adequate vitamins & minerals from their diet, but vitamins are not a substitute for a healthy diet.
