Iron Vs. Iron Sulfate as a Supplement

Iron supplements are taken to combat low blood iron, also known as anemia. Your doctor may prescribe iron supplements or suggest that you take an over-the-counter dietary supplement, depending on your condition.

Iron Sulfate

• People with certain health conditions should not take iron sulfate.

  Iron sulfate, also known as ferrous sulfate, is the most common form of iron supplement. It is most often used to treat iron deficiency anemia. Iron sulfate should be taken on an empty stomach at least one hour before or two hours after a meal. Avoid taking multivitamins or antacids with iron sulfate. This supplement is not appropriate for people who are alcoholics, pregnant women, those who receive regular blood transfusions, or those who suffer from a lack of red blood cells. The most common side effects of taking iron sulfate are constipation, black stools, nausea and a temporary staining of the teeth.

Iron

• Iron supplements are available both by prescription and over the counter.

  In cases of extremely low blood iron, nonsulfate forms of iron may be administered. These supplements can be taken orally, or, in some cases, administered intravenously. Oral iron supplements have many of the same side effects as iron sulfate, including stomach upset, constipation, dark or black stools and diarrhea. Some people tolerate nonsulfate iron supplements better than iron sulfate. Like iron sulfate, oral iron supplements should be taken on an empty stomach with a full glass of water.

Conclusion

• A doctor can best determine what type of iron supplementation you need.

  Which iron supplement is best for you depends on a number of factors: how low your blood iron is, what other medications and supplements you may be taking, other conditions you may have or are being treated for, and the reason for your anemia. A doctor can make the best recommendation. Consult your health care practitioner before beginning iron supplementation.
