The recommended iron intake for a woman over 60 is 8 milligrams per day, according to the National Institutes of Health. However, depending on the woman's diet and the amount of exercise she gets, this amount may vary.
Iron supplements most often come in capsule or pill form. The body absorbs iron supplements best when taken on an empty stomach. An individual should not consume caffeine, milk, calcium or high-fiber foods when taking an iron supplement, notes MedlinePlus. Side effects of taking too much iron may include nausea and diarrhea. Consulting a doctor can help a woman over 60 determine the correct iron supplement dosage for her.
